At the same time, cold can increase blood viscosity and fragility of tiny blood vessels, and it is also the high incidence and recurrence period of cardiovascular and cerebrovascular diseases, such as hypertension and coronary heart disease.
Dr. Xu Fuping from the Center for Preventive Treatment of Diseases of Guangdong Provincial Hospital of Traditional Chinese Medicine reminded that it is particularly necessary to prevent cold and strengthen yang in winter in order to adapt to the changes of seasons after winter.
Keep warm: never let your feet and back get cold.
As the saying goes, "cold starts from the feet", the feet are far away from the heart, the subcutaneous fat is weak, the heat preservation ability is weak, and it is easy to catch cold. Although the overall surface area of the sole is small, the blood vessels and nerves of the sole are very sensitive, which can easily spread to the brain center, stimulate the cerebral cortex, and cause the decline of immune defense function. Chinese medicine believes that the foot is the foundation of the human body, and the five internal organs of the human body have corresponding projections on the foot. Foot is also the beginning of foot Sanyin Meridian, and the end of foot Sanyang Meridian. Many acupoints distributed on foot correspond to five zang-fu organs through meridians.
Xu Fuping said that "foot massage" can relieve fatigue, prevent diseases and preserve health. The temperature of foot bath water should be around 40 degrees Celsius, not too hot, and the amount of water should be submerged in the ankle joint. You can even add some angelica, cinnamon, Morinda officinalis, Eucommia ulmoides and Achyranthes bidentata to soak your feet with traditional Chinese medicine to promote blood circulation and smooth qi and blood.
It is necessary to keep your back warm. From the meridian of traditional Chinese medicine, the back is the du meridian of the sun and the circulating part of the bladder meridian. Du meridian always leads to the yang of the whole body, and the sun passes through the surface of the whole body, so the wind and cold hit the back and the back bears the brunt. If the back is not well kept warm, the pathogenic wind-cold can easily damage the yang through the exterior, leading to diseases. He said that for chronic debilitating diseases, the elderly or children, it is particularly necessary to keep your back warm. The way to keep warm can be to wear an extra vest, sweater vest, thermal underwear or scarf around your shoulders and neck.
Protecting Yang: Sunbathing Yang Qi.
"The sun shines on people. If the sun is in the sky, it will lose its life if it does not show its strength." Sunlight is one of the most important conditions for human survival. It can not only promote the absorption of calcium, but also relieve depression and relax. At the same time, it can also promote the synthesis of melatonin, which is conducive to improving the quality of sleep. Lao Heng-yan pointed out that "sit with your back to the sun" and Liezi called it "the mystery of negative sun". The slight warmth of the spine can make the whole body harmonious. The sun is the essence of the sun, and its light makes people yang. Of course, you can't be exposed to the sun too much, so as to avoid skin aging or damage caused by excessive ultraviolet radiation.
Food supplement: medicated diet is edible.
People have more and more mental activities, more and more consumption, less and less time to raise, and more need to be nursed back to health regularly to facilitate hair growth. As the saying goes, "If you don't store sperm in winter, you will get sick in spring."
Winter tonic needs targeted tonic according to physical fitness and human state, and is suitable for people with sub-health and chronic weakness syndrome such as long-term fatigue, physical decline, forgetfulness, inattention, insomnia and anxiety, and skin relaxation. Not all people need supplements. Xu Fuping explained that people with weak gastrointestinal function at ordinary times can't make supplements by force. They should adjust their stomachs first and then make supplements step by step. The strength of tonic is different, such as clearing tonic, warming tonic and re-tonic, and the way of tonic is also different from food tonic and medicine tonic.
Warm tonic is mainly sweet, such as chicken, duck and fish. Warm supplements include beef and mutton, and fruits and vegetables should be eaten as little as possible.
There are three kinds of drugs for invigorating qi and blood, nourishing yin and strengthening yang: Radix Codonopsis, Radix Astragali, Rhizoma Dioscoreae, Atractylodis Macrocephalae, Radix Rehmanniae Preparata, Radix Angelicae Sinensis, Fructus Lycii, Mori Fructus, Corni Fructus, Lily, Radix Ophiopogonis, Ganoderma, Eucommiae Cortex, Morinda Officinalis, Cortex Cinnamomi and Semen Cuscutae. You can also cook some soups and medicated diets, such as yam Gordon Euryale porridge, duck stewed with Radix Adenophorae and Yuzhu, and hawthorn lipid-lowering drink.
Reminder: There are some details to know about the post-beginning of winter movement.
Moderate exercise in winter can enhance physical fitness, prevent diseases and preserve health. But exercise should also pay attention to the following three points:
First, winter exercise should be carried out after the sun comes out, go to bed early and get up late, walk with the sun and coordinate with the natural biological clock. Especially for the elderly, don't get up too early in winter exercise. In winter morning, the temperature is low, the climate is cold, the endocrine metabolism is slow, the small blood vessels in the whole body have protective contraction, the blood is sticky, and the blood resistance increases, which is prone to cardiovascular and cerebrovascular diseases.
Second, morning exercises should try to avoid smog weather, which is very harmful to human body. The core substance of smog is smog, dust and other substances suspended in the air. Gas can directly enter and attach to the lower respiratory tract and lungs of human body, which is harmful to human health. In addition to wearing masks and other protective measures, you should wait until the sun rises and the smog clears before exercising.
Third, it is not appropriate to engage in fatigue war in sports, and it is not appropriate to measure it by how much you sweat. It is cold in winter, and many people often evaluate their exercise by sweating. Everyone's physique is different, and the degree of sweating is also different. Wet clothes are more likely to cause colds after sweating a lot. Exercise is suitable for personal comfort, and some people who don't exercise often have no time to exercise. Once they start exercising, it's hard to stop. Excessive exercise will wear out joints and destroy the balance of exercise, which requires an adaptation process. Therefore, exercise should choose the appropriate winter exercise prescription according to age, physical condition and climate characteristics.
