Sleep, as we know, is important to us because it helps restore tired organs and tissues in Our body. But how much sleep do we actually need? For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep, and sonic who may even use more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our & when we awaken.
They’re actually different levels of sleep. There is deep sleep and shallow sleep. In a shallow sleep, our body does not get the same kind of £eBt it gets a deep sleep so that after eight hours of a shallow sleep we still feel tired. But a short, deep sleep can be very restful.
Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give the command to attack!
Normally when we go to sleep, our “sleep center” blocks off nerves so that both our brain and our body go to sleep. Ono prevents us from wanting to do anything, and the other makes our internal organs and limbs go to sleep. But sometimes only one goes to sleep and the other does not. A very tired soldier can sometimes fall asleep (brain sleep) and keep on marching because his body is not asleep!
Why Do I Always Wake Up At 3am?
wake up at 3 a.m. or another time and can’t fall right back asleep, it may be for several reasons. These include lighter sleep cycles, stress, or underlying health conditions.
