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.
Rough night last night? Everyone has a bad night of sleep now and then.
Your life won't wait until you're rested, so you'll need all the energy you can to get through today. Some of the nation's leading sleep doctors offer tips on how to power through the day after a bad night's rest.
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.
