Sleep plays a vital role in good health and well-being throughout your life. During sleep, your body is working to support healthy brain functioning and maintain your physical health. The damage from sleep deprivation might not hurt you instantly but it’s a safe bet it will harm you over time if it continues for a long time. For example, ongoing sleep deprivation can raise your risk for chronic health problems such as depression, high blood pressure, obesity, diabetes, and various heart problems. The ancient Greeks were the first people to realize the importance of sleep in people’s lives and for that reason they worshiped Morpheus (god of sleep and dreams), to whom they prayed for a good night’s sleep and peaceful dreams. Today, however, since the rhythms of modern life are more demanding and stressful than ever before, many people tend to suffer from insomnia (mainly due to stress and anxiety) or intentional sleep deprivation in an attempt to achieve more than a normal human being should in a day. In case you’re one of those people who don’t fully realize the importance of sleep, take a look at these 25 Cool Facts About Sleep You Probably Didn’t Know and we can promise you that you will make a few changes in your life starting today.
