Traditional Chinese medicine believes that cold is yin evil and often hurts yang. Huangdi Neijing said: "Yang is like the sun in the sky, giving light and warmth to nature. Without it, nothing can survive. " If there is no yang in the human body, the body will lose the vitality of metabolism, unable to supply energy and heat, and life will stop. In winter, some old and weak people often feel that their hands and feet are not warm, they are afraid of cold and prefer warmth. This situation is usually called "insufficient firepower", which is called "yang deficiency" by Chinese medicine. It is very important for myasthenia gravis patients to maintain health in winter: tonifying kidney and preventing colds.
(1) mental conditioning
In the cold winter, the north wind is cold, the sun hides, the cathode, the vegetation withers, and the natural stinging insects are hidden, so that they can recharge their batteries in hibernation and prepare for the coming spring. The metabolism of yin and yang in human body is also at a relatively slow level, and transformation is better than qi transformation. Therefore, winter health should be based on "hiding". Specific to the mental activities of the human body, especially how to hide it? Huangdi Neijing has already clearly pointed out: "In winter and March, this is to hide ... to hide one's ambition, to have private interests and to do something", which means that people should keep quiet in winter, try their best to control their mental activities, and it is best to hide them, just like keeping personal secrets, especially as satisfying as getting the treasures they desire. Its central idea is: people should hide God inside in winter, and don't expose it outside, which is just the opposite of the method of adjusting God in summer.
Prolonging the light time: Because the light time is short in winter, it is an important reason for depression. Studies have found that when night comes, the secretion of melatonin in the pineal gland of the human brain is enhanced, which can affect people's mood, and light can inhibit the secretion of this hormone.
Appropriate physical activity, because physical activity can regulate the autonomic nerve function of the body, inhibit the overly excited sympathetic nerve, and relieve the tension, anger, anxiety, depression and other emotions caused by autonomic nerve dysfunction.
Eat more fresh vegetables and fruits rich in vitamin C, as well as beans, milk, peanuts and animal offal rich in vitamins B 1 and B2. If vitamin C and B vitamins are lacking, it will affect the function and mood of the brain.
(2) Diet aftercare
In the severe winter, the cold is pressing, and the physiological activities of the human body need more heat energy to maintain. Chinese medicine believes that winter should be the time when the human body's yang is hidden, that is to say, the physiological activities of the human body will converge due to the influence of winter climate characteristics, and a certain amount of energy will be stored in the body to prepare for the "spring comes and summer grows" in the coming year. At the same time, there should be enough energy to maintain more expenditure of heat energy in winter and improve the body's disease resistance.
The nutritional characteristics of winter meals are as follows.
① Increase heat: ensure sufficient heat energy suitable for catching cold and activity intensity. The supply of protein is limited to the required level at room temperature, and the increase of calories should be ensured by increasing the supply of carbohydrates and fats. The supply of inorganic salts should be kept slightly higher at room temperature.
② Adequate vitamin supply: Special attention should be paid to increasing the demand for vitamin C. Take enough animal food and soybeans to ensure the supply of high-quality protein, appropriately increase oil, of which vegetable oil should reach more than half, and ensure the adequate supply of vegetables, fruits and milk. If you can meet the above requirements, you can resist the cold in winter; Ensure good health. If the patient's carbohydrate-based diet with starch as the main food often fails to meet the body's needs for various nutrients intake, leading to the decline of the body, low disease resistance and easy to catch a cold.
In addition, patients with myasthenia gravis should eat less salty and bitter food.
Avoid sticky cold food in winter diet, because this kind of food belongs to yin, which is easy to damage the spleen and stomach yang. In addition, for normal people, the winter diet should follow the principle of "nourishing Yang in autumn and winter, not disturbing Yang", that is, eating some diets with high calories, such as lotus root, fungus and flax, which are all beneficial foods. In order to avoid vitamin deficiency, we should eat more fresh vegetables, such as spinach and rape.
