Can’t focus? It’s hard to do when you haven’t slept. You’ll also have trouble learning new stuff. And when you do, you’ll need some shut-eye to remember it. Doctors call this consolidation -- sleep strengthens the links between brain cells that form memories. That’s what makes learning stick.
Sleepy drivers cause at least 100,000 highway crashes a year. Nodding off at the wheel isn’t the only problem. A lack of rest can lead to a drop in what doctors call mental performance. You’re less motivated, focused, and happy. And you don’t think as clearly. This doesn’t just apply to road warriors. One study showed hospitals could cut mistakes by more than a third if they gave doctors more time to sleep.
Do you get a little snippy when you’re short on sleep? That’s normal. Just one bad night can make you sad, stressed, angry, and tired. If the trouble lasts, you may start to feel worse about your life. You might not want to hang out with friends and family. Over time this can lead to mood disorders like depression or anxiety. A better sleep routine is the answer. Talk to your doctor if it doesn’t help or if your symptoms get in the way of your life.
It’s a triple whammy. If you haven’t slept, it’s harder to recall things. You also need sleep to create bonds between brain cells that strengthen your long-term memory. Finally, if your mind’s all over the place due to lack of rest, it’s harder for it to file away the things you want to remember.
Not as many rolls in the hay? Maybe you and your partner need a little more shut-eye. Lack of sleep can zap your testosterone levels. That can make both women and men feel less frisky. If you're a woman, just 1 extra hour of sleep makes it more likely that you'll get your groove on the next day.
With these reasons ,I hope you find it very essential to sleep adequately and most importantly for us humans,to live longer
