When you are young, your mother tells you several things about your health that may cause you to question whether she is telling you the truth. Rules such as no swimming for at least 15 minutes after eating, no playing in the rain or you’ll catch a cold, and no going outside during winter without gloves and a hat or you’ll catch pneumonia may have given you pause when you were a kid because the consequences of not listening could have been dire. As you get older, you take your chances and sometimes wish you would not have done that cannonball right after eating hot dogs at the Labor Day picnic.
While she may not have known exactly why a lack of sleep could make you sick, your mother definitely was right in telling you to get enough sleep or you would get sick. Of course, we all know that sleep deprivation makes us feel sluggish, makes it difficult to concentrate, and makes us cranky, but we may not realize the very real toll that a lack of sleep takes on our health. People who do not get enough sleep are at a greater risk of developing serious health issues like heart disease, heart attack, heart failure, irregular heartbeat, high blood pressure, stroke, and diabetes. By some accounts, 90% of people with insomnia also have another health condition.
Lack of sleep also contributes to symptoms of depression; in fact, in the U.S., people who are diagnosed with depression or anxiety are likely to sleep fewer than six hours a night. Sleep deprivation and depression often exacerbate one another, becuase lack of sleep aggravates depression symptoms, and depression often makes it more difficult to fall asleeep.
Lack of sleep has been linked to weight gain as well. According to researchers, people who get less sleep than they should are more overweight than people who get enough sleep. This associateion between sleep deprivation and obesity affects both children and adults. Poeple who stay awake longer have more opportunities to eat, and lack of sleep affects key hormones that control appetite, so sleep-deprived people may be hungrier than individuals who get enough sleep.
