Most people sleep at night.Some countries have traditionally had nap times, such as Espanyah and Latin America.But the entire time spent sleeping is similar to people who don't take a nap.A newborn sleeps several times during the day or at night.I take a nap when I am two to three months old, but I learn how to sleep at night.Almost all children don't take a nap at the age of six.I sleep 10 to 14 hours a day on average at the age of four.The average adult needs eight and a half hours of sleep.Many older adults suffer from sleep disorders such as insomnia and sleep apnea.All activities are reduced, muscles are relaxed, and heart rate and breathing are slowed down. And as you fall asleep, you slowly become unconscious of what's happening around you. A person changes posture at least 12 times while sleeping, and the head, arms and legs move much more often.The deeper you fall asleep, the slower your brain becomes.People who can't sleep are not energetic and get angry easily.If you don't sleep for two days, it's hard to concentrate for a day.These people make simple decisions and are good at long hours of work, but they make a lot of mistakes because they are easily distracted and sometimes they areIf I don't sleep more than three days, I have a lot of trouble thinking, seeing, and listening. A person can stay up to 11 days without sleep.But a person who hasn't slept for so long loses his sense of reality and doubts and fears others. Sleep plays an important role in rejuvenating the brain and nervous system.
