Everybody yawns -- Even unborn babies in the womb -- and yet researchers aren't quite sure why we do it. -- Although humans yawn more often when we're tired or bored, scientists have ruled out sleepiness or lack of oxygen(which would cause sleepiness) as causes. Instead, they suspected yawing might help us keep a cool head. As with a supercomputer, the brain needs to stay cool to function properly. Each yawn pumps air into sinus cavities in the head, cooling the brain in the process. And because the brain and body are slightly warmer just before bed, we tend to yawn when we're tired.
WHY do we need to SLEEP???
Video games, track meets, chemistry class -- your waking hours are crammed with activities and tasks that give your noggin a real workout. All that processing causes chemicals to clutter your brain. A good nights sleep cleaned your head -- literally. While you snooze, your brain goes into housekeeping mode, flushing the toxins and preparing itself for a busy day of math classes, socializing, and beating your brother in basketball.
How much sleep do I need???
That depends on your age, kids between 5 and 12 need about 11 hours of sleep. Older kids and adults can get by with 7 or 8 hours.
Why is Yawning contagious????
Yawns don't catch on among children younger than five or among people with emotionally dampening disorders. That leads researchers to believe contagious yawning Is just another way humans reinforce social bonds between people, humans are social and emotional animals. We tend to understand and feel the emotions of friends and even strangers. Yawning falls into that category, when we see someone, we yawn.
Is Yawning contagious for other animals besides humans????
You bet, at least among higher parameters such as chimpanzees and bonobos (for the same reason as for humans, researchers suspect). Even more surprising show that dogs catch yawns from watching people!!
What happens if I don't get enough sleep???
Doctors believe that a good night's sleep come with many benefits, including improve creativity and mental sharpness. Avoid going to bed and you will soon suffer the consequences crankiness, clumsiness --- even hallucinations if you miss a few days. Your brain will go on strike, and easy tasks will become supremely difficult until you turn in and switch off.
Why do I get sleepy? ??
Whenever you try to defeat drowsiness to finish one more Harry Potter chapter, you are actually locked in a losing battle over bedtime with your brain stem. This chunk of gray matter at the base of your brain regulates your sleep, along with other automatic bodily functions such as breathing and the ticking of your heart..
