Back in the 1950s, about 7.5 hours of sleep a night was the norm for most Americans, according to a USA Today article. These days, the average American sleeps for around 6.5 hours a day, and if you’re a full time student chances are you get even less. So how DO we all function with so much less sleep? That’s a whole night of sleep, missing from our lives each week. Unfortunately, cutting back on sleep seems to have become the norm in our society.
Studies have shown, however, that we need 7-8 hours of sleep a night to be high-functioning during the day. It is a common belief that sleeping in on week-ends will somehow balance out the sleep debt incurred during the week. However, once one starts cutting sleep during the week again, there is a significant effect on alertness, mood, and performance. A study in 1995 found that there is significant sleep loss in 1/3 of American adults. This state of perennial sleepiness has been estimated to cause about 2-56 billion dollars in sleep-related accidents on the road each year, and even more in lost productivity, medical illness, or shortened lifespan secondary to sleepiness or sleep pathology.
Because of both the normal aging process and modern societal pressures to succeed, our hours in the sack are continually sacrificed.
