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.

    How to Get out of a Rut: 12 Useful Ways to Get Unstuck

    How to Get out of a Rut: 12 Useful Ways to Get Unstuck

    Have you gotten into a rut before? Or are you in a rut right now?

    You know you’re in a rut when you run out of ideas and inspiration. I personally see a rut as a productivity vacuum. It might very well be a reason why you aren’t getting results. Even as you spend more time on your work, you can’t seem to get anything constructive done. While I’m normally productive, I get into occasional ruts (especially when I’ve been working back-to-back without rest). During those times, I can spend an entire day in front of the computer and get nothing done. It can be quite frustrating.

    Over time, I have tried and found several methods that are helpful to pull me out of a rut. If you experience ruts too, whether as a working professional, a writer, a blogger, a student or other work, you will find these useful. Here are 12 of my personal tips to get out of ruts:

    1. Work on the small tasks.

    When you are in a rut, tackle it by starting small. Clear away your smaller tasks which have been piling up. Reply to your emails, organize your documents, declutter your work space, and reply to private messages.

    Whenever I finish doing that, I generate a positive momentum which I bring forward to my work.

    2. Take a break from your work desk.

    Get yourself away from your desk and go take a walk. Go to the washroom, walk around the office, go out and get a snack.

    Your mind is too bogged down and needs some airing. Sometimes I get new ideas right after I walk away from my computer.

    3. Upgrade yourself

    Take the down time to upgrade yourself. Go to a seminar. Read up on new materials (#7). Pick up a new language. Or any of the 42 ways here to improve yourself.

    The modern computer uses different typefaces because Steve Jobs dropped in on a calligraphy class back in college. How’s that for inspiration?

    4. Talk to a friend.

    Talk to someone and get your mind off work for a while.

    Talk about anything, from casual chatting to a deep conversation about something you really care about. You will be surprised at how the short encounter can be rejuvenating in its own way.

    5. Forget about trying to be perfect.

    If you are in a rut, the last thing you want to do is step on your own toes with perfectionist tendencies.

    Just start small. Do what you can, at your own pace. Let yourself make mistakes.

    Soon, a little trickle of inspiration will come. And then it’ll build up with more trickles. Before you know it, you have a whole stream of ideas.

    6. Paint a vision to work towards.

    If you are continuously getting in a rut with your work, maybe there’s no vision inspiring you to move forward.

    Think about why you are doing this, and what you are doing it for. What is the end vision in mind?

    Make it as vivid as possible. Make sure it’s a vision that inspires you and use that to trigger you to action.

    7. Read a book (or blog).

    The things we read are like food to our brain. If you are out of ideas, it’s time to feed your brain with great materials.

    Here’s a list of 40 books you can start off with. Stock your browser with only the feeds of high quality blogs, such as Lifehack.org, DumbLittleMan, Seth Godin’s Blog, Tim Ferris’ Blog, Zen Habits or The Personal Excellence Blog.

    Check out the best selling books; those are generally packed with great wisdom.

    8. Have a quick nap.

    If you are at home, take a quick nap for about 20-30 minutes. This clears up your mind and gives you a quick boost. Nothing quite like starting off on a fresh start after catching up on sleep.

    9. Remember why you are doing this.

    Sometimes we lose sight of why we do what we do, and after a while we become jaded. A quick refresher on why you even started on this project will help.

    What were you thinking when you thought of doing this? Retrace your thoughts back to that moment. Recall why you are doing this. Then reconnect with your muse.

    10. Find some competition.

    Nothing quite like healthy competition to spur us forward. If you are out of ideas, then check up on what people are doing in your space.

    Colleagues at work, competitors in the industry, competitors’ products and websites, networking conventions.. you get the drill.

    11. Go exercise.

    Since you are not making headway at work, might as well spend the time shaping yourself up.

    Sometimes we work so much that we neglect our health and fitness. Go jog, swim, cycle, whichever exercise you prefer.

    As you improve your physical health, your mental health will improve, too. The different facets of ourselves are all interlinked.

    Here’re 15 Tips to Restart the Exercise Habit (and How to Keep It).

    12. Take a good break.

    Ruts are usually signs that you have been working too long and too hard. It’s time to get a break.

    Beyond the quick tips above, arrange for a 1-day or 2-days of break from your work. Don’t check your (work) emails or do anything work-related. Relax and do your favorite activities. You will return to your work recharged and ready to start.

    Contrary to popular belief, the world will not end from taking a break from your work. In fact, you will be much more ready to make an impact after proper rest. My best ideas and inspiration always hit me whenever I’m away from my work.
