why sleep is important?
Most teens need about 8½ to more than 9 hours of sleep each night. The right amount of sleep is essential for anyone who wants to do well on a test or play sports without tripping over their feet. Unfortunately, though, many teens don't get enough sleep. I am the one that have this problem because at night I didn’t sleep because I often spent my time with TV, talk to my friends, games computer, etc. I found the research in my mom’s book, it said….
Why Is Sleep Important?
This sleep deficit impacts everything from a person's ability to pay attention in class to his or her mood. Research shows that more than 20% of University students fall asleep in class, and experts have been able to tie lost sleep to poorer grades. Lack of sleep also damages teens' ability to do their best in athletics. Slowed responses and concentration from lack of sleep don't just affect school or sports performance, though. The fact that sleep deprivation slows reaction times can be life threatening for people who drive. The National Highway Safety Traffic Administration estimates that 1,500 people are killed every year in crashes caused by drivers between the ages of 15 and 24 who are simply tired. (More than half of the people who cause crashes because they fall asleep at the wheel are under the age of 26.) Lack of sleep has also been linked to emotional troubles, such as feelings of sadness and depression. Sleep helps keep us physically healthy, too, by slowing our body's systems enough to re-energize us after everyday activities.
I think, it is easy to know that you are getting enough sleep. Even if you think you're getting enough sleep, you may not be difficulty waking up in the morning, falling asleep during classes, etc. And if you have this problem, I think you need more sleep.
So, I think, get enough sleep is important thing because if we don’t get enough sleep, it will effect to our health and then our education and our works. So, we must get enough sleep for ourselves.
