The importance of Sleep

The importance of Sleep

Most of us don’t sleep enough or without problems and aren’t fully aware of the importance of sleep and if that’s your case too than I recommend you read this 3 part series on sleep which just appeared in The New Yorker written by Maria Konnikova.

Here’s the introduction of the first article and below you will find the links for the original articles:

Why Can’t We Fall Asleep?

Here’s what’s supposed to happen when you fall asleep. Your body temperature falls, even as your feet and hands warm up—the temperature changes likely help the circadian clocks throughout your body to synchronize. Melatonin courses through your system—that tells your brain it’s time to quiet down. Your blood pressure falls and your heart rate slows. Your breathing evens out. You drift off to sleep.

That, at least, is the ideal. But going to sleep isn’t always a simple process, and it seems to have grown more problematic in recent years, as I learned through a series of conversations this May, when some of the world’s leading sleep experts met with me to share their ongoing research into the nature of sleeping. (The meetings were facilitated by a Harvard Medical School Media Fellowship.) According to Charles Czeisler, the chief of the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital, over the past five decades our average sleep duration on work nights has decreased by an hour and a half, down from eight and a half to just under seven. Thirty-one per cent of us sleep fewer than six hours a night, and sixty-nine per cent report insufficient sleep. When Lisa Matricciani, a sleep researcher at the University of South Australia, looked at available sleep data for children from 1905 to 2008, she found that they’d lost nearly a minute of sleep a year. It’s not just a trend for the adult world. We are, as a population, sleeping less now than we ever have.

 

 

 

 

The problem, on the whole, isn’t that we’re waking up earlier. Much of the change has to do with when we choose to go to bed—and with how we decide to do so. Elizabeth Klerman is the head of the Analytic and Modeling Unit, also in the Sleep and Circadian Disorders division at Brigham and Women’s Hospital. Her research tracks how multiple individual differences in our environment affect our circadian rhythms and our ability to fall asleep easily and soundly. “When you go to bed affects how long you can sleep, no matter how tired you are,” she told me..
