why sleep is important?

Students who have trouble grasping new information or learning
new skills are often advised to “sleep on it,” and that advice seems
well founded. Recent studies reveal that people can learn a task better
if they are well rested. They also can remember better what they
learned if they get a good night’s sleep after learning the task than if
they are sleep deprived.

Sleep gives your heart and vascular system a much-needed rest.
During non-REM sleep, your heart rate and blood pressure progressively
slow as you enter deeper sleep. During REM sleep, your heart
rate and blood pressure have boosted spikes of activity. Overall,
however, sleep reduces your heart rate and blood pressure by about
10 percent.

Deep sleep triggers more release of growth hormone,
which fuels growth in children and boosts muscle mass and the
repair of cells and tissues in children and adults. Sleep’s effect on
the release of sex hormones also encourages puberty and fertility.

Lack of sleep can reduce
the ability to fight off common infections. Research also reveals
that a lack of sleep can reduce the body’s response to the flu vaccine.

During sleep, the body’s production
of the appetite suppressor leptin increases, and the appetite stimulant
grehlin decreases. Studies find that the less people sleep, the
more likely they are to be overweight or obese and prefer eating
foods that are higher in calories and carbohydrates. People who
report an average total sleep time of 5 hours a night, for example,
are much more likely to become obese compared to people who
sleep 7–8 hours a night.
