We all need sleep, that's something our body needs to rest and revitalize our minds. One of sleep's original function is to save energy. Animals for example may be efficient at certain times of the day, some are more efficient at night while for others would be during the day. So sleep conserves energy during the inefficient time.
People who don't get enough sleep have trouble concentrating and become more vulnerable to illness, especially mental illnesses, for example stress and depression.We decrease the amount of sleep we get as we get older, so we should learn to manage our sleep time correctly. Infants usually get 16-17 hours of sleep as babies, children get 11-13 hours, as adolescents we get about 9 hours of sleep and as adults the average is about 8 hours although some people can go through the day with just 3 hours of sleep.
Sleep also plays an important role for memory. One way for sleep to strengthen memory is by wedding out the less successful connections. That means that by weakening synapses during sleep emphasizes the ones that were strengthened during wakefulness. With new knowledge and information we need to store this information, but if we had stored all the information we've ever learned our brain wouldn't be able to sustain much new information, so that's why some of that information needs to be removed and new one processed in.
Our health is a major importance when we are talking about the amount of sleep we get. The less sleep we get the more prone we are to getting sick. Depression and stress are some of the main health risks that one can face. We react to sleep deprivation as if we were ill. With more prolonged sleep deprivation,people report dizziness, tremors, and hallucinations.
clearly, we need to sleep, not only for our health, but so that we can be able to function properly.
So true! If I slept 3 hours or less in consecutive days I would instantly get sick. I have learned to listen to my body and try to avoid ever having to sleep 3 or less hours. It always starts with an headache or migraine and ends up as a cold. Now these days people are in such a hurry to get so much done and we sacrifice our health to get it done. I agree with you, we need to be aware of how sleep is vital for physical and mental health and wellness.
ReplyDeleteyes sleep its very necessary to function well through out the day. It is very important to sleep the needed hours to recover energy, and be able to do our regular rutines with out complaining all day because of lack of sleep.
ReplyDeleteI find that I require about 7 hours of sleep to feel well-rested during the week. Even if I don't set an alarm, I tend to wake up after about seven hours. When I was in high school, I used to be able to pull all-nighters and function pretty well the next day. Now? Not so much. Even if I try to stay up all night, I'll end up falling asleep somehow. Getting older kind of sucks. :(
ReplyDeleteEven if I do manage to stay up all night, throughout the next day, I don't really feel sick, per se. However, I DO get a little dizzy and my surroundings feel very surreal. Almost like I'm in a dream, but not quite the same. I remember having to drive to class and take a test on no sleep a couple of years ago. I'm pretty sure I went right to bed when I got home. Needless to say, it's not a pleasant feeling.
