Modern people, not only the elderly pay attention to health, but also young people, especially young women. People who know how to keep in good health are generally at the forefront of consciousness. People with high education pay more attention to health, so they pay more attention to health preservation. And how to keep fit? Can you make your body the best? This is a problem that many people are actively looking for and acting on. The ancients said: "Don't look for immortals, look for sleeping parties, have a deep sleep, and all diseases will disappear." Now that living conditions are getting better and better, people pay more and more attention to health. In order to live a long and healthy life, people adopt various methods such as exercise, nutrition and nourishing the whole body, but the first tonic for health preservation is nothing more than deep sleep. "Nothing is better than deep sleep." Deep sleep is the most familiar and fragrant stage in human sleep. During deep sleep, people's cerebral cortex cells are in a state of full rest, which can play a role in maintaining cortical cells, which is extremely important for stabilizing emotions, balancing mentality and restoring energy. During deep sleep, the secretion and release of pituitary growth hormone reach a peak, human metabolism is maintained at the lowest basic level, and energy consumption is reduced. At the same time, it strengthens the anabolism of related tissues and organs in the body, increases energy, restores the physical strength of people who have been tired for a day, and stores energy for later use. Sleep is the "charger" of the human body, the best "tonic", the "defense line" against diseases and the "beauty time" for deep sleep. First, how to ensure a good sleep: There are many reasons for insomnia, but its root lies in the imbalance between matter and body. In order to ensure a good sleep, you need to do "five noes": 1 before going to bed, and you are not full: Chinese medicine says that "stomach disharmony leads to restless sleep", because people need to rest at night and their spleen and stomach also need to rest. Eating too much will increase the burden on the spleen and stomach, disturb the yang of the spleen and stomach, and thus affect sleep. Therefore, dinner should be seven or eight minutes full, as light as possible, protect the spleen and stomach, and clear the yang. 2, but don't move: it is not appropriate to do strenuous exercise before going to bed and disturb the yang, including watching TV before going to bed, talking and chatting and other activities that disturb the yang. Moreover, the radiation of TV, audio and other electrical appliances will interfere with the autonomic nerves of the human body. Therefore, it is not advisable to do strenuous exercise, watch TV or chat half an hour before going to bed. 3, Dan Si: the spleen dominates thinking, thinking more hurts the spleen, and thinking more is easy to disturb the mind. Thinking is yang, sleeping is yin. Therefore, it is advisable to recuperate before going to bed, so as to "sleep first and then sleep" and help yang enter yin to facilitate sleep. 4, but not too late: 1 1 pm later, the gallbladder meridian opens yang and is pneumatic, which makes people easy to lose sleep, easily dissipates the qi of the liver and gallbladder, and makes foreign evils invade the body. So it's best to go to bed at 2 1, not later than 22: 30. 5, free from the wind: the wind is the beginning of all diseases, pervasive. Sleeping at night, opening the window and turning on the air conditioner will blow away the yang on the body surface of the guards. After being blown away, Yang will regenerate and be blown away by the wind after regeneration. This will dry people's yang overnight and make them more tired the next day. Therefore, close the doors and windows and air conditioning before going to bed to protect the yang on the body surface. Second, when is sleep beneficial to health: 9 pm to 3 am is an effective sleep time and the best sleep time. Sleep less than half an hour at night (2 1 -3), and sleep for more than three hours during the day can't make up for it. Therefore, it is suggested that you grasp the effective sleep time, and it is best to sleep at 9 pm, not later than 10: 30. 1, 2 1-23 o'clock every day is the time to go to sea, and the triple energizer meridian is the most prosperous, belonging to the triple energizer meridian of hand shaoyang, "the triple energizer connects the pulse"; At 23:00- 1:00, the gallbladder meridian is the most prosperous, belonging to the gallbladder meridian of foot shaoyang. One is that the hands are not yang, and the other is that the feet are not yang. What is shaoyang? Shaoyang is the rising sun! Only when people enter the actual sleep state before 23 o'clock can the sun of the human body rise and have a good physical and mental state. Most centenarians go to bed before 9 pm. 2, 65438+ 0-3 am ugly, the liver meridian is the most prosperous. Huangdi Neijing says that "blood belongs to the liver when people lie down", and the best time for nourishing blood and producing blood in the liver is 2 1- 3 am. If people stay up until 1 o every day, the liver can't get back blood, toxic blood can't be discharged, fresh blood can't be born, and human viscera can't be nourished by qi and blood, which is very easy to get out of balance and cause disease. Third, the role of sleep health care: 1, eliminate fatigue, restore physical strength: sleep is the main way to eliminate physical fatigue. Because of the function of gastrointestinal tract and its related organs in sleep, human energy substances are synthesized and manufactured for activities. In addition, due to the decrease of body temperature, heart rate, blood pressure, respiration and some endocrine, the basal metabolic rate is reduced, so that physical strength can be restored. 2, protect the brain, restore energy: lack of sleep, manifested as irritability, excitement or listlessness, inattention, memory loss and so on. Long-term lack of sleep can lead to hallucinations. People who get enough sleep are energetic, quick-thinking and efficient. This is because the oxygen consumption of the brain is greatly reduced during sleep, which is beneficial to the energy storage of brain cells. So sleep is good for protecting the brain and improving brain power. 3. Enhance immunity and restore the body: Under normal circumstances, the human body can produce antibodies against various invasive antigen substances and remove them through immune reaction to protect human health. Sleep can enhance the body's ability to produce antibodies, thus enhancing the body's resistance; At the same time, sleep can also accelerate the self-healing of various tissues and organs. In modern medicine, sleep is often used as a treatment to help patients through the most painful period, which is conducive to the rehabilitation of diseases. 4. Promote growth and development: Sleep is closely related to children's growth and development. The baby's brain continues to develop for a long time after birth, and it is inseparable from sleep; And children grow faster during sleep, because plasma growth hormone can maintain a high level for several hours during sleep. Therefore, it is necessary to ensure that children get enough sleep and ensure their growth and development. 5. Delaying aging and promoting longevity: In recent years, many survey data show that healthy and long-lived elderly people have good normal sleep. Human life is like a burning flame. Regular burning makes life last. If it burns up and down, it will shorten the time and make people die young. Sleep time is like minimal flame burning, so it can delay aging and ensure longevity. 6. Protecting people's mental health: Sleep is very important for protecting people's mental health and maintaining normal psychological activities. Because of poor sleep for a short time, there will be inattention, and after a long time, it will cause abnormal situations such as unreasonable thinking. 7, conducive to skin beauty: during sleep, skin capillary circulation increases, its secretion and clearance process is strengthened, and skin regeneration is accelerated, so sleep is conducive to skin beauty.
