Inhaltsangabe

For many of us, sleep is one of life's greatest pleasures. For others, sleep represents a nightly struggle to fall asleep, stay asleep, rest comfortably, and
even remain safe until morning. But what is sleep exactly, and why must we do it every night?

Despite the fact that we spend about one-third of our lives in slumber, scientists still aren't completely certain. Finding the function of sleep is one of the biggest-and most intriguing-challenges facing biologists today.

What is clear: Sleep is as essential to life as food and water. It impacts virtually every aspect of our lives, from our mood to the functioning of our organs, and it contributes to learning and memory, better performance at work, and a more healthy and productive wakeful life overall.

A lack of sleep impairs your cognitive abilities, exacerbates or leads to psychological problems, and leaves you vulnerable to a long list of chronic medical issues. And the consequences of too little sleep extend beyond the personal. From causing auto accidents to factoring into major disasters such as the Exxon Valdez oil spill, sleep deprivation imposes a heavy toll on society.

Clearly, there's tremendous value in studying sleep that goes far beyond mere fascination. Educating yourself on the subject may, without exaggeration, save your life or the life of someone you love. The frightening reality is that dire consequences can develop after only a few days of inadequate sleep.
