Study Finds Sleep-Deprived People Can’t Read Facial Expressions

Study Finds Sleep-Deprived People Can’t Read Facial Expressions

A recent study shows that the lack of sleep can affect the way you perceive people’s emotions, so if you’re starting to feel like the world is against you, it may be time to clock in some zzz’s.

It’s time to stop stretching your waking hours to accommodate too many things in your career and social calendar. Adding to the many reasons why you shouldn’t scrimp on sleep, a recent study published in the Journal of Neuroscience shows that the lack of sleep curtails our ability to read facial expressions. This means that without proper sleep, our brain is not able to properly decipher the moods of people around us, making interaction and decisions based on our impressions more difficult.

Researcher Matthew Walker, a professor of psychology and neuroscience at UC Berkeley, explains:

“The better the quality of dream sleep, the more accurate the brain and body was at differentiating between facial expressions”.

The Brain – Heart Disconnect

The experiment comprised of 18 healthy young adults who were asked to viewed 70 facial expressions that ranged from friendly to threatening. The test showed that there was a huge difference in the way their brain reacted to seeing the facial reactions after a full night of sleep, and then later after 24 hours of being awake.

The researchers monitored the brain activity and heart rate of the participants in both scenarios. The results show that without sleep, the brain is less able to stimulate the anterior insula and the anterior cingulate cortex, its emotion-sensing regions. They also found that when sleep deprived, the brain is unable to send distress signals to the heart, creating a different physical response to what would normally be experienced during emotional situations. Participants who weren’t able to get a full night’s rest were interpreting most facial reactions, including friendly and neutral ones, as threatening and negative emotions instead.

    Work Hazards

    Walker finds this as a major cause of concern as he relays:

    “Two-thirds of people in the developed nations fail to get sufficient sleep”.

    This is an alarming finding since sleep deprivation is a common phenomenon, and it is not uncommon for people to consider sleep as a lesser priority to their deadlines and social commitments. Consider how this affects you on a daily basis. The less sleep you get, the less able you will be to properly interact and communicate with the people around you. Our ability to read expressions properly allows us to form our impressions and judgement of people, which in turn results to how we react in various situations. This over estimation of threat caused by the lack of sleep can cause you to react to the most neutral of situations as a cause of emotional concern and stress. Next time you’re sleep deprived and feeling paranoid that people are giving you a stink eye, it might actually all just be in your head.

    This poses a more significant level of threat to individuals with jobs that require quick response to highly stressful situations but are prone to sleep-deprivation. These are the people who are expected to make important decisions based on first impressions and intuition. The study lead author Andrea Goldstein-Piekarski, a postdoctoral fellow at Stanford University (who has been working on the study since he was a Ph.D. student at UC Berkeley), notes:

    “Consider the implications for students pulling all-nighters, emergency-room medical staff, military fighters in war zones and police officers on graveyard shifts”.

    We have been told time and again that sleep is an important factor to attain complete physical, mental, and emotional wellness. Understand that the harm of sleep deprivation is a very real thing. If you or your loved ones have been getting less sleep than recommended, it is time to make a change. Save yourself from awkward situations and poorly calculated decisions. Turn off the lights, pry your eyes away from your phone, and tuck yourself in. A conscious effort to snooze off as scheduled can help your mind and body function like a well-oiled machine.

    7 Ways To Make Exercise Fun For Everyone

    7 Ways To Make Exercise Fun For Everyone

    From Atkins to Paleo to eating gluten-free despite not being one of the rare few people afflicted with celiac disease, fad diets are everywhere. It drives me crazy because I believe these diets do more harm than good. Your body is made up of a variety of vitamins, nutrients, and minerals, and losing weight healthily isn’t possible when you fill your body with unnecessary synthetic plastics, sugars, and powders. There’s no easy button in life.

    What you need to do is exercise, which isn’t very appealing to many people. Workouts take work, so there’s already a stigma involved in going to the gym. Starting a healthy workout regimen becomes easier when you make it fun. If you want to live long and prosper, get off the couch and try these methods to turn your workout into a playout.

    1. Take the scenic route.

    Walking is an easy way to transition to a healthy lifestyle, and it’s free. Not only do you burn calories (check out this calculator for how many calories you burn based on your weight), but you see the world in a different way. Hiking in nature is great if you have access to it, but don’t let living in an urban area deter you from walking.

    Whenever I’m creatively stuck I get my head straight by walking a couple of miles. It’s also how I discover new paths, meet new people, and stumble upon hole-in-the-wall spots I never would have found otherwise. You could drive past the same place every day and never appreciate the beauty, nor even notice it’s there.

    2. Distract yourself.

    No matter what exercise routine you choose, use the time to meditate. You may wonder how marathon runners are able to put so many miles on their bodies. It’s because the pain from running that you avoid is something they’ve learned to harness to enter a transcendental state. If you’re aware of the benefits of meditation and exercise but don’t have time to do both, you can combine them, killing two birds with one healthy stone.

    3. Listen to music or podcasts.

    There are few experiences in life more pleasurable than turning up the music and drowning out the world around you. With so many podcasts and music apps available on your smartphone, you can easily find entertainment options perfectly suited to your personal tastes. Never worry what people may think of you when working out;instead, crank up the volume and get lost in your own world. You’ll be in shape before you know it.

    4. Bring a friend.

    Some people can’t go anywhere alone. While I highly recommend dining out and seeing a movie in a theater alone, having company while exercising is very helpful. It allows you to pace yourself with someone else, and gives you a coach to motivate and push harder than you may have on your own.

    Many exercises are safer when done with a friend, and some sports can only be played with another person. Involving others in your goals can mean the difference between success and failure. Just remember to continue exercising if the other person flakes, or they’ll be in control of your health.

    5. Accessorize.

    There are accessories that can make exercise easier, and sometimes buying a new toy can add some much-needed fun to your routine. With apps like RunKeeper and Nike+, your smartphone is capable of tracking your vitals and progress. Wrist weights can add a new dimension to your workout, and, if you exercise at night, a headlamp can help you see what’s in front of you so you don’t trip.

    For urban runners and power-walkers, one of the biggest obstacles is other people. It’s difficult to get in your meditative zone and enjoy your music when you constantly have to dodge people. To resolve this vexing issue, Runbell, a startup in Tokyo, has developed the runner’s version of the bicycle bell. With this lightweight brass bell warning people you’re approaching from behind, you’re free to maintain your transcendental state while continuing your workout. Head to their Kickstarter campaign to pledge your support.

    6. Compete.

    A little healthy competition can motivate you to push yourself further in your workout regimen. There are apps like Zombies, Run! which turns your run into a video game, and MyFitnessPal which allows you to connect with others in the exercise community. Whether you’re directly competing with a friend, an online community, or against your previous self, setting goals is the key to reaching them. Running with no destination can feel like an impossible task, and it’s easy to get distracted.

    7. Relax.

    The best part about exercising is how much you enjoy the downtime. If you think laying on your couch all day is enjoyable, it has nothing on that hour you spend as a couch potato after a rigorous workout. Jay-Z said it best, “in order to experience joy, you need pain.” The harder you push yourself while exercising, the better you’ll feel when you’re relaxing.

    With that said, don’t relax too much, or it loses the effect. It’s okay to indulge every so often. Treat yourself to some junk food you’re craving, imbibe a drink here and there, and spend a day vegging out on your couch. Staying healthy doesn’t have to be torture. Just turn down when you can and dedicate some time to better the health of your body. You only get one.
