On World Sleep Day, sleeping too much can be as dangerous to heart health as sleeping too little. Sleeping poorly is painful, but the fear and anxiety of not sleeping well can make insomnia even worse. Too much sleep is not enough. People with physical illnesses tend to have poor sleep quality, and in turn, chronic sleep disorders are an important cause of chronic fatigue syndrome, hypertension, coronary heart disease, diabetes, and cerebrovascular disease. The impact of sleep on coronary heart disease in particular needs to be taken seriously. Statistics show that the number of people who die from various coronary heart diseases in China is more than 1 million every year, of which, 30% died suddenly in the middle of sleep. Studies have shown that the length of sleep is closely related to the mortality rate of cardiovascular diseases. People with poor heart function are often advised to “get enough rest”, but sleeping too long may not be a good thing. Zhang Jinbei pointed out that too much sleep, a person’s sympathetic nerves are inhibited, parasympathetic nerves are active, along with the body’s hormone secretion changes, which affects the heart function. “Sleep state, a person’s heart rate will slow down, if you sleep too long, for people with a slow heartbeat, may lead to insufficient blood oxygen supply.” He said that sleeping too little is more likely to result in accidents due to the higher energy consumption of the person’s activities in the waking state and the high load on the heart. Overhyped “insomnia phobia” In recent years, the problem of insomnia has been overhyped and turned into “insomnia phobia”. This is related to the over-hyped advertising of sleeping pills and sleep-aid related products. Advertisements tend to interpret the consequences of insomnia as catastrophic, such as wrinkles, dark circles under the eyes and premature aging in women, thus causing fear and anxiety. It is normal to have a few days of poor sleep due to various factors and can be adjusted. However, this anxiety and fear of “not sleeping well” may have a reinforcing effect, making the quality of sleep worse and worse. Many people with insomnia start out with a few days of poor sleep, then they start to worry about the quality of sleep, and under the effect of anticipatory anxiety, they get excited every time they go to sleep, and they toss and turn, but they can’t sleep, and as a result, they really become insomniacs. The dusk exercise is more helpful than the bedtime exercise. There are various ways to help you sleep, which one works better? Counting sheep is a long-rumored method of associating sleep aid, but some users pointed out that it does not meet the habits of Chinese people, because sheep (English sheep) and sleep (English sleep) sound similar, for the Chinese people, should count dumplings (harmonic “dumpling”). In this regard, regardless of whether it is counting sheep or dumplings, in fact, there is no effect, but because of the increased activity of the cerebral cortex, the more people count the more mental. The principle of hypnosis is to let yourself relax before going to bed. When you are busy at work or in a bad mood, there are times when you can’t sleep well, but as long as you adjust properly, you won’t have insomnia continuously. He contributed his own sleep secrets: 1, the bed is only used to sleep, and only when there is a sleepy feeling to go to bed. Instead of lying in bed and tossing and turning, why not get up and do some activities. 2, really can not sleep, may wish to look at boring books, English, medical and legal books have a fairly good hypnotic effect. 3, to improve the quality of sleep, dusk is more suitable than before going to bed to do exercise. Climbing, walking, jogging, tai chi, swimming, etc., moderate activity, sleep-aiding effect is better.
