1, how to achieve deep sleep “deep sleep” is the most sleepy and fragrant stage of the body, when the body’s metabolic rate will increase significantly, the body’s immune function, damaged cells and the nervous system for normal repair, and accelerate the synthesis of brain tissue protein and the replenishment of consumable substances. Adequate “deep sleep” is the guarantee of physical and intellectual development for children, energy for adults, and a long and healthy life for the elderly. The proportion of sleep stages is more important than the duration in terms of sleep quality. If you sleep for 6~8 hours, you should get 13%~23% of “deep sleep”, that is, 1-2 hours of “deep sleep” in a night, to be considered a good sleep. This wake up, you will feel refreshed, fatigue all gone. 2, a short nap to relax the mood after lunch visceral activity, the brain is relatively calm, the brain can easily enter a resting state when napping, the proportion of deep sleep is high. Napping can help us relax, sort out the morning to receive a variety of stress, is the heart in the work of the day pause button. Take a nap at noon, more than coffee or tea to help recover from fatigue. A healthy nap should be 15 to 30 minutes most appropriate. If more than 30 minutes, the inhibition process of the brain deepens, many capillary network in the brain tissue temporarily closed, the brain blood flow is relatively reduced. Wake up at this stage, the inhibited brain and closed capillaries have not yet opened, so that the brain appears to be temporarily undersupplied with blood, feeling “sleepier and sleepier”, the purpose of the nap decompression will not be achieved. 3, can’t sleep don’t rush to eat sleeping pills poor sleep quality, dreamy people, can use short-acting or medium-acting drugs, the half-life of these drugs is slightly longer, 6 ~ 8 hours, can deepen the slow-wave sleep and shorten its time; early awakening insomnia, should use medium-acting or long-acting drugs, the half-life of these drugs is long, 12 ~ 15 hours, can extend the total sleep time. Some people have chronic poor sleep and live on sleeping pills at night. Doctors advise such people to ask themselves the question: Why can’t I sleep? Is it because of the coffee or the joint pain? Figuring out the cause of insomnia can solve the problem fundamentally. For insomnia caused by anxiety and depression, sleeping pills can’t help. So some long-term insomnia, the effect of medication is not good, you need to refer to a psychologist to see if you have psychological problems. 4, the principle of sleep “sleep at night and get up early” The normal sleep after spring, should be “sleep at night and get up early”. The plan of the day lies in the morning, as early as the “Yellow Emperor’s Classic of Internal Medicine” has a brilliant assertion, “sleep at night and get up early, walk widely in the court, be hair to walk slowly, in order to make the will to be born”. It means that people should adapt to the changes in nature, sleep late and get up early, go for a walk outdoors, stretch their limbs leisurely and look forward to the spiritual activities in nature. After meals, before bedtime leisurely stroll, not only can eliminate food and gas, but also thoughtless, mind and body to recuperate, refreshing. In addition, it should also be noted that the spring wood when the order, hyperactive temperament of the people appropriate old disease recurrence. As the saying goes: yellow flowers yellow, crazy busy. However, this condition can be prevented or alleviated by properly increasing sleep, meditation and recuperation, and examining the causes and identifying the treatment, which can prevent or alleviate the development of the disease. In the spring flowering season, which is also a period of high prevalence of pollen allergy sufferers, staying away from pollen zones appropriately can play a preventive role. There are four seasons in heaven, spring, summer, autumn and winter, and people grow old and strong. By following the natural and human nature, conforming to the laws and characteristics of climate change throughout the year, and reasonably adjusting sleep and health in all seasons, we can strengthen the body’s ability to adapt to nature and avoid diseases.
