A Time to Look at Some Myths and Facts About Sleep
There are many common myths about sleep. As National Sleep Awareness Week approaches, the National Sleep Foundation takes a look at six common myths and the facts that dispel them.
Myth #1: Sleep is not important. I can just get by on a few hours.

But when its time for them to sleep, their irregular schedule works against their body clock, and they may find it difficult to get a full 7-9 hours of sleep. Despite the challenges, shift workers need just as much sleep as those who work traditional hours, though they are at an increased risk for sleepiness as well as the common health risks that come with insufficient sleep such as high blood pressure and heart problems.

Fact: Insomnia can be a serious medical condition characterized by difficulty falling asleep, difficulty staying asleep (waking up often during the night and having trouble going back to sleep), waking up too early in the morning or feeling tired upon waking. Several consequences of insomnia
