Not everyone has to sleep for seven hours.Ensuring effective sleep is very important for everyone’s normal life. For the elderly, because of age, it is enough to sleep for 5~6 hours every day. But these 5~6 hours must be an effective sleep time, that is, the time of deep sleep.Those who seem to be sleeping, in fact, are in a state of “like sleeping but not sleeping” or “hazy”, which is not effective sleep. Four hours of effective sleep is far better than eight hours of sleep waiting for the morning. Therefore, the sleep quality of the elderly can not be simply measured by how much time is guaranteed. In addition, if the elderly are suffering from diabetes, hyperlipidemia and severe arteriosclerosis, too much sleep time may be harmful to their health. Because people have slow blood flow, slow heart rate and low blood pressure in deep sleep, this situation may not be dangerous for some elderly people who have no basic diseases, but for those who have the above diseases, it is easy to cause small thrombus attached to the wall. Once this happens in brain blood vessels, cerebral infarction may occur. This is the reason why clinically common cerebral infarction often occurs at night.

Cardiovascular and cerebrovascular diseases don’t go backwards for fitness.SCMany elderly people like walking backwards to keep fit, but walking backwards is not suitable for the elderly suffering from cardiovascular and cerebrovascular diseases such as hypertension, hyperlipidemia and coronary heart disease.When walking backwards, you need to straighten your waist or lean back slightly, so that your spine and lumbodorsal muscles will bear more strength than usual. However, because of the deterioration of your body function, the elderly can’t keep your body in balance effectively, and it is easy for them to suffer from dizziness, falling and other risks due to cerebral or myocardial ischemia. In addition, when you walk backwards, you will turn your head or twist your waist from time to time, which will easily cause the carotid artery to be compressed, resulting in narrowing of the lumen, which will lead to insufficient blood supply to the brain and lack of oxygen.Therefore, the elderly with cardiovascular and cerebrovascular diseases had better choose jogging, walking, Tai Ji Chuan and other sports step by step, so as not to induce myocardial infarction and cerebral infarction.
