Go to bed! Getting less than six hours of sleep can have major effects on your health and appearance
Yahoo Health has created a handy infographic that explains reasons why getting enough sleep is VERY important. According to the infographic lack of sleep affects your looks, your mood, and generally your health. Read some of the effects broken down below:
Your Mental Capacities
“One of the most important things we have to remember is that sleep is a function of the brain,” Shalini Paruthi, MD, associate professor in the department of internal medicine and pediatrics at Saint Louis University, and spokesperson for the American Academy of Sleep Medicine, tells Yahoo Health. When you don’t get enough sleep, the mental effects are immediate. They range from having a harder time concentrating and making decisions to having headaches and struggling to remember things, which can impact your life both personally (forgetting a friend’s birthday) and professionally (blanking mid-presentation in front of your boss).
Your ability to react quickly also slows down when you’re exhausted — which results in making mistakes. “We first lose our speed, and then we lose the accuracy,” notes Paruthi. “There are multiple studies that show being deprived — even if it’s four hours of sleep — can make someone have the same reaction time as someone who is driving under the influence. Driving while sleep-deprived is the equivalent of driving drunk.”
Your Mood
And let’s not forget about mood. “Your ability to regulate and control your emotions, as well as [cope] with change, are affected,” she says. That’s a nice way of saying that you’re more likely to be grouchy and irritable when you’re short on sleep. Research shows that getting less than five hours of sleep at night can make you feel more stressed, sad, and angry.
Your Heart
One study involving 3,000 adults over the age of 45 found that those who slept under six hours each night were nearly twice as likely to have a stroke or heart attack compared to adults who logged six to eight hours per night, according to the National Sleep Foundation. They were also 1.6 times more likely to have congestive heart failure. Another smallstudy conducted by Mayo Clinic researchers found that not getting enough shut-eye significantly raises blood pressure at night.
Your Blood Sugar Levels
Blood sugar levels are affected, too. In one study, healthy men who were restricted to four hours of sleep six nights in a row showed impaired glucose tolerance — a prediabetic condition.

Your Immune System
Anyone who has ever gotten a cold shortly after pulling an all-nighter knows that sleepless nights can also weaken your immune system. A recent study found that people who slumber for six hours or less at night are four times more likely to catch a cold when exposed to the virus, compared to those who sleep more than seven hours each night. “People who are sleep deprived may not be able to mount the same type of immune response as someone fully replete on their sleep,” says Paruthi.
Your Metabolism
Missing out on sleep may also be the reason your skinny jeans are feeling a little tighter these days. Being just shy of two hours of your usual amount sleep at night can slow down your metabolism. And other research shows it can rev up your appetite: A study published in the Journal of Sleep Research found that just one night of not getting enough sleep raises ghrelin levels — the hormone that signals hunger to the brain.
Your Appearance
A lack of shut-eye also affects your appearance. There’s a reason they call it beauty sleep: A 2013 study in the appropriately named journal Sleepfound that people rated photos of sleep-deprived adults as looking less than their best — with redder eyes, darker under-eye circles, and more fine lines and wrinkles — compared to photos of the same adults when they were well-rested. The study participants even went on to say that the adults in the photos looked sadder when they were sleep-deprived, than after a good night’s sleep.
Your Love Life
As if that weren’t enough, sleep deprivation can even mess with your relationship. Couples have a harder time resolving conflicts and have more frequent and serious fights when they don’t get enough sleep, according to a 2013 studypublished in the journal Social Psychological and Personality Science.
