WHY SOME PEOPLE ARE ALWAYS LATE

Confession: I am a late person. At least, one in recovery. In fact, I’ve repeatedly, and embarrassingly, missed the deadline for this article. I’d love to pretend this is some journalistic form of ‘method’ acting. It is not.
I know I’m not alone. We all know that person: there’s the child minder who is always late, the colleague who misses every deadline, even if just by a few hours, the friend you must tell to arrive 30 minutes earlier than she needs to for your lunch reservation.
Despite what may be running through your mind as you’re kept waiting, it’s unlikely your friends and colleagues are just being selfish
There are few habits as infuriating as someone making us wait. But, despite what may be running through your mind as you’re kept waiting again, it’s unlikely your friends and colleagues are just being selfish. A look into the psychology of lateness offers a glimpse into a mind that that may be malfunctioning. But there’s also more than one fix.

No, late people aren’t rude and lazy
Perceptions of unpunctual people are almost always negative — even if misguided.
“It is easy to perceive them as disorganised, chaotic, rude and lacking in consideration for others,” says Harriet Mellotte, a cognitive behavioural therapist and a clinical psychologist in training in London. “Outside of my clinical practice, others being late is something that can particularly get under my skin!”
The punctually-challenged are often excruciatingly aware and ashamed of the damage their lateness could do
But, many late people are at least somewhat organised and want to keep friends, family and bosses happy. The punctually-challenged are often excruciatingly aware and ashamed of the damage their lateness could do to their relationships, reputations, careers and finances.
“While there are those who get a charge out of keeping others waiting, if you’re typical, you dislike being late,” Diana DeLonzor writes in her book Never Be Late Again. “Yet tardiness remains your nemesis.”

Excuses, excuses
Some excuses, particularly for acute lateness, are fairly universally accepted —an accident or illness, for example. But others aren’t so easy to swallow. Some late people will pass it off as a symptom of being big-thinking and concerned with loftier matters than time-keeping, as an endearing quirk, a mark of doing one’s best work under pressure, or having the body clock of a night owl rather than a lark.
Joanna, a teacher in London who didn’t want her surname used, says her reputation for being unpunctual can sometimes be attributed to a difference in opinion. “A friend will ask me to come over, and they’ll say ‘come any time from seven,’” she says. “But if I do turn up at eight or later, they’re annoyed.”
Being consistently late might not be your fault. It could be your type. The punctually-challenged often share personality characteristics such as optimism, low levels of self-control, anxiety, or a penchant for thrill-seeking, experts say. Personality differences could also dictate how we experience the passing of time.
In 2001, Jeff Conte, a psychology professor at San Diego State University ran a study in which he separated participants into Type A people (ambitious, competitive) and Type B (creative, reflective, explorative). He asked them to judge, without clocks, how long it took for one minute to elapse. Type A people felt a minute had gone by when roughly 58 seconds had passed. Type B participants felt a minute had gone by after 77 seconds.

You are your own worst enemy
Late people often have a “bizarre compulsion to defeat themselves,” wrote self-proclaimed late person and TED speaker Tim Urban in 2015. He gave these poor souls a name: CLIPs, Chronically Late Insane People.
Of course, there are other reasons for lateness, but many remain self-inflicted. For starters, there’s the anticipation of being late, or even too much attention to detail.
For Joanna, the most distressing example is writing school reports. “I never make the deadline, which looks like I don’t care,” she explains. “I think about [the reports] for weeks, and put so much angst into really assessing each child. But the fact that they are late undermines that.”

For some, lateness is a “consequence of deeply distressing common mental health or neurological conditions,” says Mellotte.
“People with anxiety diagnoses often avoid certain situations,” for instance, says Mellotte. “Individuals with low self-esteem are likely to be critical about their abilities which may cause them to take more time to check their work.” And depression often comes with low energy, making mustering the motivation to get a move on all the harder.
Fix your brain, be on time? 
Dr Linda Sapadin, a psychologist in private practice in New York and author of How to Beat Procrastination in the Digital Age says, says some persistent lateness comes from “an obsessive thinking problem.”
Change the word ‘but’ to ‘and’ the task becomes less daunting
In short, she says, the procrastinator focuses on a fear attached to the event or deadline for which they are running late. Rather than figuring out how to get beyond the fear, the fear becomes the excuse – usually expressed with a ‘but’ statement. For instance, you might tell yourself, “I wanted to be on time for that event but I couldn't decide what to wear; I started to write an article but I was afraid my colleagues would find it not good enough,” she explains.
“Whatever comes after the 'but' is what counts,” says Sapadin. She tells people to change the word ‘but’ to ‘and’. ‘But’ denotes opposition and blockage; ‘And’ denotes connection and resolution, she explains, so “the task becomes less daunting, the fear less of an obstacle.”

If you’re sick of being left waiting by tardy friends, set boundaries and consequences for missing appointments (Credit: Getty Images)
DeLonzor started on her path to punctuality by identifying, and adapting the very thing that seemed to always make her late. That was only after she failed over and over again to improve her timeliness, she says. And then she realised it was the thrill of being rushed that she craved. Changing what she craved was the only way to improve.
“As I worked towards the goal of being more timely, I began to see the importance of being a reliable person,” DeLonzor says, “Developing that side of myself soon became a priority.”
Then there are the friends and loved ones who simply can’t take it anymore. Some of Sapadin’s clients arrive after a frustrated loved one has bought them a session or course with her.
Instead of getting angry or upset, you can take a stand and set boundaries
For those left waiting, there is hope. You, too, can dictate what you’re willing to put up with.
“Instead of getting angry or upset, you can take a stand and set boundaries,” she says. “Talk about what you will do if the other person isn’t on time.” For instance, tell your late friend you’ll go into the movie without them if they’re more than ten minutes late. Tell that colleague who never turns his part of the project in on time that it just won’t be included next time — and the boss will know about it.
For me, a turning point came when a good friend drew her line in the sand. I was an hour late for a run in our local park. That was it, she said. She wasn’t going to make any more plans with me. And so she set in motion the best thing for me: accountability and identifying and addressing underlying problems that led to my perpetual lateness.
As the adage goes, old habits die hard, and the agonising over this article is a deft illustration of that. But the next time I find myself keeping someone waiting, I’ll be looking at my thinking, and I’ll try to change it, even just a little.

THE SCIENCE OF BEING CHARMING

Most of us have come across them at some point - the kind of people who can walk into a room full of strangers but then leave with 10 new friends, a lunch date for the next day, and the promise of an introduction to an industry insider.   
Charmers. What makes these lucky individuals so effortlessly likeable when many of us have to work so hard at it? While many would have you believe social grace or winning people over is something of an artform, there is a surprising amount of science behind it too.
The factors that determine our success with other people, and the impressions we make upon them, can start even before we meet them. Research has proven the people we meet often make judgements about us based purely on the way we look. Alexander Todorov, a professor of psychology at Princeton, has shown that people can make judgements about someone’s likeability, trustworthiness and competence after seeing their face for less than a tenth of a second.

“While some things, like dominance, are highly related to morphological features, there are things like trustworthiness and even attractiveness which are highly dependent on facial expressions,” says Todorov, whose book Face Value: The Irresistible Influence of First Impressions explores this phenomenon.
Making a snap judgement on something so superficial might seem rash, but we do it all the time without even realising. And it can have serious implications. For example, it might influnce who you vote for. One study showed that facial appearance can be used to predict the outcome of elections to the US Senate. Similarly, facial characteristics associated with competence have also been successful in predicting the outcomes of elections involving BulgarianFrenchMexican and Brazilian politicians.
The judgements we make about someone’s face can influence our financial decisions too. In one experiment, borrowers who were perceived as looking less trustworthy were less likely to get loans on a peer-to-peer lending site. Lenders were making these judgements based on appearance in spite of having information about the borrowers employment status and credit history at their fingertips.
Put on a happy face
Of course, while you may not be able to control the physical features of your face, it is possible to alter your expressions and smile. Todorov has used data-driven statistical models to build algorithms that can manipulate faces to look more or less trustworthy, allowing him to tease out the features that we trust the most.
According to his work, as a face becomes happier, it also becomes more trustworthy.
  People will perceive a smiling face as more trustworthy, warmer and sociable
“People will perceive a smiling face as more trustworthy, warmer and sociable,” explains Todorov. “One of the major inputs to these impressions is emotional expression. If you look at our models and and manipulate the faces to become more trustworthy or extroverted, you see the emotional expression emerge—the face becomes happy.”

For those situations where our first impression has not been as good as we might have hoped, there is also hope – we can still win people over so they forget that initial snap judgement.
“The good news is that we can very quickly override our first impression made based on appearance,” says Todorov. “If you have the opportunity to meet someone, the moment you have good information about them, you will change the way you perceive them.” If you can impress someone, they will often forget about what they thought when they first saw us, even if it was negative.
Channel your charm
This is where charm can come in. Olivia Fox Cabane, an executive coach and author of The Charisma Myth, defines charm as likability and “how delightful it is to interact with someone.”
Contrary to popular depictions, being likeable can have its benefits in business. Entrepreneurs with better social skills are more likely to be successful and workers who are well liked are better at getting their way at work. A study by the University of Massachusetts, for example, found that internal auditors who were well liked and provided an organised argument were more likely to have managers agree with their proposals, even if manager would otherwise tend to disagree with the auditors position if they had not met them.
Suzanne de Janasz, an affiliated professor of management at Seattle University, says interpersonal skills are becoming increasingly important in the workplace as organisations have done away with older, hierarchical structures in recent years.
“It’s become more germane, more critical, to have the ability to work in teams and influence with or without an actual title,” she says.

Best of all, it’s possible to train yourself to be charming. Jack Schafer, a psychologist and retired FBI special agent who is a likeability coach and author of The Like Switch, points to Johnny Carson as a quintessential example of someone who preferred being alone, but who learned how to be extremely sociable for the camera. The late host of The Tonight Show would go years without giving interviews and once told the LA Times that 98% of the time he went home after the show rather than choosing to socialise with the glitterati.
“Carson was an extreme introvert who trained himself to be an extrovert,” says Schafer. “As soon as the show was over he curled up and went home, but on TV he was famous for smiling and laughing and making jokes.”
Raising eyebrows
So what can the rest of us do to be more charming? Schafer says charm starts with a simple flash of the eyebrows.
The three major things we do when we approach somebody that signals we are not a threat is an eyebrow flash a slight head tilt, and a smile
“Our brains are always surveying the environment for friend or foe signals,” he says. “The three major things we do when we approach somebody that signal we are not a threat are: an eyebrow flash - a quick up and down movement of the eyebrow that lasts about a sixthof a second - a slight head tilt, and a smile.”
So now you have made your entrance – hopefully without gurning like a maniac – experts agree that the next key to likability is to make your interaction about the other person. That means not talking about yourself.
“The golden rule of friendship is if you make people feel good about themselves, they’re going to like you,” says Schafer. Cabane agrees, but says it can only work if you show a geninue interest in what they are saying.
“Imagine the other person is a character in an indie flick,” she suggests. “Those characters become more fascinating the more you learn about them. You’ll find yourself observing and showing genuine interest in their mannerisms and personality.”
Focus on the different colours in their irises. By maintaining that level of eye contact, it will give the impression of interest
If that fails, she says interest can also be faked. “Focus on the different colors in their irises,” she says. “By maintaining that level of eye contact, it will give the impression of interest.”
Schafer suggests making empathic statements that might reflect some of what the other person is feeling.
“I once saw a student in an elevator who looked pleased with himself,” he explains. “I said ‘It looks like you’re having a good day.’ He went on to tell me about how he just aced a test he had spent weeks studying for. That entire exchange made him feel good about himself.”
If you know more about the person you’re speaking with, you can be even more effective.
“Instead of direct flattery, you want to allow people to flatter themselves,” he says. “Once I find out your age I can say something like, ‘you’re in your 30s and write for the BBC? Not many people can do that so young’. Now you’re giving yourself a psychological pat on the back.”
In a networking situation – something many people dread - you may have heard something about the person you’re speaking with, allowing you to bring up specific topics that are relevant to them. “You can say, ‘I heard that this great thing happened for you, I’d love to hear the story,’” suggests de Janasz.
Find common ground
De Janasz also suggests emphasising common ground, even when your opinions diverge. Charming people are often skilled at finding common ground with the people they interact with, even when there’s not much to go on.

“When you disagree, try to really listen to the other person rather than setting up your response, which research shows smart people tend to do,” she says. “It might seem like you totally disagree but on closer examination you might agree on a few things, at least in principle.”
She adds that it’s always a good idea to keep up with current events, and industry news, since those are the things most people have in common. Schafer also advises looking for common ground contemporaneously (You’re from California? I’m from California), temporally (I’m hoping to visit California next year) or vicariously (My daughter works for a firm in Silicon Valley).
Watch their body
Another key to likeability is to mirror the body language of the other person. When people are conversing and they begin to mirror one another, it is a signal that have a good rapport, says Schafer.
“So you can use that and mirror them so you can signal to them that you have good rapport,” he says. It is also a good way to test how the conversation is going – if you change your own position and the other person copies you, it is probably going well. Anyone working in sales might want to use that moment to start their pitch.
Schafer recommends revealing details about yourself little by little – like bread crumbs - so each new piece of information acts as “curiosity hooks” to keep their interest going
If you are looking to give your relationship with your new best friend some longevity, it might also be worth using something Schafer refers to as the Hansel and Gretel technique. A common mistake that many of us make is to overwhelm new people with too much information about ourselves, which can put them off. Instead, Schafer recommends revealing details about yourself little by little – like bread crumbs - so each new piece of information acts as “curiosity hooks” to keep their interest going.
“You gradually release information about yourself to keep the relationship alive,” he explains.

There will be, however, situations where you will need to get someone to like you unnaturally fast. If that’s the case, Schafer, whose 20 years at the FBI included getting people to divulge secret information, has strategies for getting people to answer personal questions.
Presumptive statements like “You sound as if you’re 25 to 30”, will often lead the other person to respond with a confirmation like, “Yes, I’m 30”, or a correction, “I’m 35”. Another approach might be to use quid pro quo, where offering personal details of your own life usually results in reciprocation.
Research has found that the quicker I can get someone to answer personal questions, the quicker that relationship is going to advance
“Research has found that the quicker I can get someone to answer personal questions, the quicker that relationship is going to advance,” says Schafer. “So if I’m selling something, the more quickly I develop rapport and get you to say all sorts of intimate details about your life, the faster you will treat me as a friend and the faster I can get to my sell.”
If all else fails, simply spending time near someone can make him or her like you, even in extreme circumstances. Schafer opens his book with an anecdote from the FBI about a foreign spy who was in American custody. Everyday Schafer sat in his cell quietly reading the newspaper until eventually fear gave way to curiosity and the spy wanted to start a conversation.
“So initially it was proximity and duration,” says Schafer. “And then I gradually introduced intensity, leaning toward him, increasing eye contact, et cetera.” It took months, but Schafer ultimately got what he wanted.
So next time you walk into a room filled with new faces, with a bit of effort it might be you that everybody wants to get to know.

On New Year’s day, a team of pranksters changed the famous hillside sign that looms over Hollywood to ‘Hollyweed’, celebrating a new law that makes recreational use of marijuana legal. It was a timely intervention, argued Kelly Grovier, noting that John Berger died the following day: the British art critic was “responsible for helping make audiences aware of how vulnerable cultural icons are to manipulation,” said Grovier, “changing the way popular audiences responded to the use of works of art by those with the power to reproduce them.” (Credit: Gene Blevins/AFP/Getty Images)

An extraordinary photo, taken in the battle-ravaged Syrian city of Aleppo, was shared widely in March. Shot in the ruined, bomb-rattled home of Mohammed Mohiedin Anis (also known as Abu Omar), and showing the 70-year old collector of vintage cars smoking a pipe while listening to music on a record player, the image was “a mute dirge to the savage devastations of war”, according to Grovier.

“The shape of the world is hanging by a thread – or rather, according to experts, by a 110 mile-long (177km) rift,” wrote Grovier in response to a photo showing a rapidly expanding crack in the Larsen C ice shelf in Antarctica. The aerial image, taken in November 2016 by Nasa scientist John Sonntag, was back in the news in May with the announcement that a second rift had been detected. In July, a large portion was reported to have broken from the shelf, creating one of the largest ice bergs ever to break off Antarctica, and a new crack appeared to be extending northwards.

A photo of a man in Alberta, Canada mowing his lawn while a tornado loomed behind him went viral in June. It was “a masterclass in nonchalance”, argued Kelly Grovier, who compared it with a painting of a twister made in 1939 – the same year Judy Garland, playing the character Dorothy Gale, was swept up by a tornado in the film The Wizard of Oz.

“If you really want to understand a people, don’t study the statues they erect. Look at the ones they’ve pulled down,” wrote Grovier after images of protestors toppling a statue of a Confederate soldier circulated in the news in August. Photos of the demonstrators in Durham, North Carolina “had the aesthetic power of the climax of cultural overthrow – those slo-mo moments when the statues of Felix Dzerzhinsky, the founder of the Soviet secret police force, the Cheka, was toppled in Moscow’s Lubyanka Square in 1991, when Libyan rebels attacked Colonel Muammar Gaddafi’s statue in Tripoli in 2011, and when the saluting effigy of Saddam Hussein in Firdos Square, Baghdad, was dramatically toppled in 2003.” (Credit: Reuters/ Kate Medley)

A striking image of golfers putting calmly against an apocalyptic backdrop was shared widely in September. Showing a group playing a round at the Beacon Rock Golf Course in North Bonneville, Washington, while a wildfire raged in the tree-lined hills behind them, the photo prompted a doubletake in viewers amazed at the putters’ poise. It also reminded Grovier of other images containing “the friction of exterior menace and interior self-possession”. (Credit: Beacon Rock Golf Course/Facebook)

More apocalyptic images emerged in October, when Hurricane Ophelia left a strange haziness in parts of the UK. Looking “more like a cinematic special effect than an actual atmospheric phenomenon”, the skies above Britain were filled with Saharan dust swept up by the storm. Grovier said that “silhouetted against a sepia sunset, worldly objects suddenly darkened into something smoky and strange, surreal as solid shadows”. He compared it to The Scream by Edvard Munch, a painting that also relied for its eeriness on an atmospheric event: in that case, the eruption of Krakatoa in August 1883.

A photo that won an award in November – showing a sculpture at a 14th-Century Buddhist temple in central Thailand – was praised by Grovier for “the sense of gradual erasure that seems to deepen before us – of nature slowly eradicating every trace left by the ancient sculptor who created the ruined statue of Buddha almost 700 years ago”. With its “jigsaw of geometric joints and elbowing shadows”, revealing the Buddha’s face “as if on the verge of dissolving into the dense shatter of shapes that surround it”, the image reminded Grovier of Cubist paintings by Picasso and Cézanne.

December: How a balloon can be an emblem of hope
To mark International Human Rights Day on 10 December, an event organised by the Border Network for Human Rights allowed families that have been kept apart by the US-Mexico border to reunite for three minutes. One of the photos that emerged – showing a young girl clutching a balloon as she waited by the barrier in Ciudad Juárez, just south of El Paso, Texas – captured a tension “between the buoyancy of the lifted spirit and the reality of restricted bodies”, according to Grovier. He likened it to an image stencilled by the street artist Banksy onto Israel’s West Bank barrier in 2005, arguing that both “are pinpoints on the map of an imagined elsewhere – an ethereal hinterland of hope where all the walls dissolve”.

HOW FLYING SERIOUSLY MESSES WITH YOUR MIND

With the tiny screen bouncing around in front of us, tinny sound quality and frequent interruptions, watching a movie during a flight is hardly an immersive experience.
Yet, frequent fliers may have found themselves – or at least witnessed others – welling up at the most innocuous of films while on a long airline journey. Even lighthearted comedies such as Bee MovieBridesmaids and The Simpsons can trigger the water works in passengers who would normally remain dry-eyed if watching these on the ground.
Physicist and television presenter Brian Cox and musician Ed Sheeran have both admitted they can get a bit over-emotional when watching movies on aircraft. A new survey by Gatwick Airport in London found 15% of men and 6% of women said they were more likely to cry when watching a film on a flight than they would if seeing it at home.
One major airline has gone as far as issuing “emotional health warnings” before inflight entertainment that might upset its customers.
There are many theories about why flying might leave passengers more vulnerable to crying – sadness at leaving loved ones, excitement about the trip ahead, homesickness. But there is also some evidence that flying itself may also be responsible.
An emerging body of research is suggesting that soaring 35,000ft (10km) above the ground inside a sealed metal tube can do strange things to our minds, altering our mood, changing how our senses work and even making us itch more.

“There hasn’t been much research done on this in the past as for healthy people these do not pose much of a problem,” says Jochen Hinkelbein, president of the German Society of Aerospace Medicine and assistant medical director for emergency medicine at the University of Cologne. “But as air travel has become cheaper and more popular, older and less fit people are travelling by air. This is leading to more interest in the field.”
Hinkelbein is one of a handful of researchers who are now examining how the conditions we experience on flights can affect the human body and mind.
The humidity is lower than in some of the world's driest deserts
There can be no doubt that aircraft cabins are peculiar places for humans to be. They are a weird environment where the air pressure is similar to that atop an 8,000ft-high (2.4km) mountain. The humidity is lower than in some of the world's driest deserts while the air pumped into the cabin is cooled as low as 10°C (50F) to whisk away the excess heat generated by all the bodies and electronics onboard.
The reduced air pressure on airline flights can reduce the amount of oxygen in passengers’ blood between 6 and 25%, a drop that in hospital would lead many doctors to administer supplementary oxygen. For healthy passengers, this shouldn’t pose many issues, although in the elderly and people with breathing difficulties, the impact can be higher.

There are some studies, however, that show even relatively mild levels of hypoxia (deficiency in oxygen) can alter our ability to think clearly. At oxygen levels equivalent to altitudes above 12,000ft (3.6km), healthy adults can start to show measurable changes in their memory, their ability to perform calculations and make decisions. This is why the aviation regulations insist that pilots must wear supplementary oxygen masks if the cabin air pressure is equivalent to heights greater than 12,500ft.
Strangely, the air pressure at altitudes of over 7,000ft (2.1km) has been found to actually increase reaction times – bad news for those who like to play computer games during their flight.
But there is some research that shows there can also be small decreases in cognitive performance and reasoning at oxygen levels found at 8,000ft (2.4km) – the same as those found in airline cabins. For most of us, this is unlikely to cloud our thinking much though.
Flying also plays havoc with our other senses too
“A healthy person like a pilot or passenger should not have cognitive problems at this altitude,” says Hinkelbein. “When you have unfit people, or someone with the flu or pre-existing problems, then hypoxia can decrease oxygen saturation further so cognitive deficits become noticeable.
But Hinkelbein says the mild hypoxia we experience during flights can have other, more easily recognised effects on our brains – it makes us tired. Studies in hypobaric chambersand on non-acclimatised military personnel arriving in mountainous regions have shown short-term exposure to altitudes of at least 10,000ft (3km) can increase fatigue, but the effects could start at lower altitudes in some people.
“Whenever I am sitting in a plane after take-off, I become tired and find it easy to fall asleep,” explains Hinkelbein. “This is not the lack of oxygen causing me to lose conciousness, but the hypoxia is a contributing factor.”
Should you manage to keep your eyes open for long enough to see the crew dim the cabin, however, then you may experience another effect of the lower air pressure. Human night vision can deteriorate by 5-10% at altitudes of just 5,000ft (1.5km). This is because the photoreceptor cells in the retina needed to see in the dark are extremely oxygen-hungry and can struggle to get all they need at a high altitude, causing them to work less effectively.
Flying also plays havoc with our other senses too. The combination of low air pressure and humidity can reduce the sensitivity of our taste buds to salt and sweet by up to 30%. A study commissioned by airline Lufthansa also showed that the savoury flavours in tomato juice taste better during a flight.
The dry air can also rob us of much of our sense of smell, leaving food tasting bland. It is why many airlines add extra seasoning to the food they serve to make it palatable during a flight. It is perhaps fortunate that our sense of smell is diminished during flights, however, as the change in air pressure can also lead to passengers breaking wind more often.
And if the prospect of breathing in the bodily gases of your fellow passengers doesn’t make you feel awkward enough, it seems reductions in air pressure can also make passengers feel less comfortable. A study in 2007 showed that after about three hours at the altitudes found in airline cabins, people start to complain about feeling uncomfortable.
Combine this with the low humidity and it is little wonder we find it hard to sit still for long periods on flights. A study by Austrian researchers has shown that a long-distance flight can dry out our skin by up to 37%, and may lead to increased itchiness.
For those who are already nervous fliers, there is perhaps some more bad news.
Low levels of air pressure and humidity can also amplify the effects of alcohol and the hangover it produces the next day.

Anxiety levels can increase with hypoxia,” explains Valerie Martindale, president of the Aerospace Medical Association at King’s College London. Anxiety is not the only aspect of mood that can be affected by flying. A number of studies has shown spending time at altitude can increase negative emotions like tension, make people less friendlydecrease their energy levels and affect their ability to deal with stress.
"We have shown that some aspects of mood can be altered by exposure to cabin pressures equivalent to altitudes of 6,000-8000ft," says Stephen Legg, professor of ergonomics at Massey Univeristy in New Zealand, who is studying the impact of mild hypoxia on people. This may go some way towards explaining why passengers often find themselves crying at films more mid-flight, but most effects in scientific studies seem to only occur at altitudes above those that commercial airline cabins are set to. Recently Legg also showed the mild dehydration that might be expected on a flight can also influence mood.
"We know very little about the effect of exposure to multiple mild stressors on complex cognition and mood," he adds. "But we do know that there is a general ‘fatigue’ associated with long distance air travel, so I guess it is probably the combined effects of these concurrent multiple mild exposures that give rise to ‘flight fatigue’.
Then there is also research showing altitude can also make people feel happier.
But Stephen Groening, a professor of cinema and media at the University of Washington, believes this happiness may also manifest itself as tears. The boredom on a flight and relief given by an inflight movie, combined with the privacy of the small screen and headphones used to watch one, could lead to tears of joy, not sadness, he says.

“The configuration of inflight entertainment apparatus produce an affect of intimacy that might lead to heightened emotional responses,” says Groening. “Crying on airplanes actually consists of tears of relief, not tears of sadness.”
But Hinkelbein has uncovered another strange change in the human body that could also be messing the way our bodies normally work. A new study he conducted with colleagues at the University of Cologne, but yet to be published, has shown even 30 minutes in similar conditions to those experienced on a commercial airliner can alter the balance of molecules associated with the immune system in the blood of volunteers. It suggests the lower air pressure may cause a change in the way our immune systems work.
If flights do alter our immune systems it could not only leave us more vulnerable to picking up infections, but it could alter our mood too
“People used to think they got a cold or flu when travelling due to changes in the climate,” says Hinkelbein. “But it could be because their immune response changes while on a flight. It is something we need to research in more detail.”
If flights do alter our immune systems it could not only leave us more vulnerable to picking up infections, but it could alter our mood too. Increases in inflammation triggered by the immune system are thought to be linked to depression.
“A one off inflammatory challenge from a vaccine can produce a mood dip that resolves in about 48 hours,” says Ed Bullmore, head of psychiatry at the University of Cambridge and who studies how the immune system influences mood disorders. “It would be interesting if a 12-hour flight to the other side of the world caused something similar.”
