Why is the sleeping time of the elderly getting shorter and shorter?

There are a lot of problems in life that bother us, such as why people are particularly tired when sleeping will be very heavy, such as why the more sleepy in the summer, and then for example, when people get older, why the sleep time will be shorter and shorter.

Everything has a rule to follow, but this old man sleep time, not by themselves can decide, sometimes they especially want to sleep, but just can not sleep, favor to be especially tired and sleepy time to fall asleep. At first I did not understand why this is, and then my mother-in-law told me that people are old and not used, the body can not help, oh, so it is.

1. Biological clock has become a law, it is difficult to change

I said the law of the biological clock, that is, the old man's habits have been set, when they are young, for the home, for the child, in order to make a living, often early morning and late at night, day in and day out, year in and year out, never a good rest, the child grows up, and worry about the child's problem of becoming a family, the child has become a family and worry about the child's problem of life. In short, in their marriage with children to the old, there is no day without worry.

Because of the worry, they can not sleep well, because before the life of labor, sleep time is very short, has become a habit, a day to sleep time, probably in the brain is particularly sleepy especially tired to fall asleep, fall asleep, the brain rested, rested enough for a period of time, the brain was awakened, the work up.

2. Older restlessness, difficult to sleep

When the person's age is getting older, there should be nothing to worry about, it is time to enjoy the blessings, but most of the elderly, because of the previous life is very bitter, the accumulation of disease in the old age of the problem, either because of the blood is not good or the heart is not good, so the heart does not rest in peace, want to sleep during the day is not able to sleep, and to be in the night after how many points before you can sleep. The first thing you need to know is how many points in the evening before you can sleep, and after you fall asleep, you wake up again at five o'clock in the morning.

My mother-in-law said, if I reach a certain age will also be like her, sleep time will be very short, not want to sleep on the sleep, although I did not reach that age, but it is true, the old man is old, but also worry about, the body is not as good as the young, of course, the sleep time will be shorter and shorter.
