Sleeping is the most important thing for the elderly. The American Cancer Society found that people who sleep for a short time have an 80% chance of short life. The elderly should fall asleep before 12 every day, and ensure seven hours of sleep every day.
Alzheimer's Association research found that for the elderly who sleep about seven hours a day, brain aging can be delayed by two years. However, sleeping for more than seven hours or not enough will make the attention of the elderly worse, increase the probability of suffering from Alzheimer's disease, and increase the risk of premature death.
Because the secretion of melatonin, which determines the sleep amount of the elderly, decreases, the elderly will suffer from insomnia, while dreaminess is due to the gradual deterioration of brain function as the elderly grow older, so the sleep time of the elderly is extremely precious. If the elderly don't get enough sleep at night, they can take a nap at noon to ensure enough sleep time every day and let the brain get enough rest time. If you can, you can take a proper walk every day to ensure that your body can move, breathe fresh air, speed up metabolism and make your body and mind more enjoyable.
