With the invention of the light bulb people can now stay awake past their recommended bedtimes and do things such as watch movies, text, or do a late night project. This results in sleep deprived citizens.
The effects of sleep deprivation are serious, an increased risk of high blood pressure, heart attack, stroke, obesity and diabetes. But why do we need sleep? Sleep is a way of recharging the brain, sleep gives the brain an opportunity to process newly learned information and organize and archive memories. During sleep, the body has a chance to replace chemicals and repair muscles, other tissues and aging or dead cells. In children and young adults, growth hormones are released during deep sleep. Not only do we use sleep to recharge our body and brain but "beauty sleep" isn't a myth either sleep because it does lessen the severity of wrinkles in the face and neck, What happens if you don't get your beauty sleep? Poor sleep quality helps to negate the bad effects of cortisol, a hormone released when stressed, which can reduce immune responses.
Lack of sleep affects our thinking, our sense of humor, and personalities. I always make sure to manage my homework time to get the most sleep I can during the school week. If I don't, then my mood is affected and my mind isn't totally focused on school. I also don't feel too confident because I didn't get my "beauty sleep."
