Having a good sleepNothing feels worse than hearing your alarm clock ring in the morning when your body is screaming for a few extra hours of rest.Given the opportunity, who wouldn’t get more sleep?If I had a choice between a year of unlimited Easter candy and a year of unlimited sleep, I'd say “Bye-bye Cadbury” and “Hello, bed!”Many people don't get as much sleep as they should.Since the invention of the light bulb，people sleep about 500 hours per year less than they used to.Whether we，re kept awake by our partner's snoring or we stay up too late watching TV, we wake up tired, groggy, and cranky.No wonder the coffee industry does so well.Unfortunately, sleep deprivation has some side effects and they can't all be remedied with a little extra caffeine.Sleep deprivation doesn't just cause mental deficits; our physical abilities are diminished too.Studies have demonstrated that not sleeping can reduce glucose metabolism by as much as 40 percent.We use stored glucose for energy and sleep deprivation can interfere with how the body stores and processes itSleep-deprived athletes also experience high levels of cortisol, a stress hormone, as well as lower levels of human growth hormone, which is important for muscle repair.The Immune system is also thought to be maintained while asleep; people who don't get enough sleep tend to be more susceptible to infections and have slower healing times.
