Do you often forget things that you’re sure you know? Is it hard to concentrate on complex assignments? Do you get less than six hours of sleep a night?
If so, you’re probably not getting enough sleep. That’s right; lack of sleep can hinder you from thinking clearly and keeping your emotions at an even keel. Studies show that excessive sleepiness can hurt work performance, wreak havoc on relationships, and lead to mood problems like anger and depression.
Are you and your partner compatible in bed -- when it's time to sleep, we mean? You like to turn in early, snuggled under a pile of blankets in the pitch dark. He's a night owl, watching TV or reading into the wee hours of the night. When he finally does doze off -- oftentimes with the light still glaring -- he hardly falls into a restful slumber. Tossing and turning, he balls up the sheets and sometimes kicks them off the bed entirely. Then comes the chain-saw like snoring and sputtering, interspersed...
Many people think of sleep simply as a luxury -- a little downtime. They know they feel better when they get a good night’s sleep and worse when they don’t. But sleep actually improves learning, memory, and insight.
“You’re putting energy in the bank when you go to sleep,” says Barry Krakow, MD, medical director of Maimonides Sleep Arts and Sciences, Ltd. in Albuquerque, N.M., and author of Sound Sleep, Sound Mind: 7 Keys to Sleeping Through the Night. “On a cellular level, the body is literally repairing and restoring itself. Without it, you can’t do what you want -- physically or mentally.”
And catching up on your sleep is a bigger job than many people realize. If you get less than six hours of sleep a night for a week, for example, you’ll rack up a full night’s sleep debt -- too much to make up for with a few hours extra sleep on the weekend.
The Impact of Chronic Sleepiness
People who are sleep deprived often say they feel “foggy.” Here are three reasons.
1. Sleepiness slows down your thought processes. Scientists measuring sleepiness have found that sleep deprivation leads to lower alertness and concentration. It’s more difficult to focus and pay attention, so you’re more easily confused. This hampers your ability to perform tasks that require logical reasoning or complex thought.
Sleepiness also impairs judgment. Making decisions is more difficult because you can’t assess situations as well and pick the right behavior.
