1. What are the disadvantages of winter?
1: Trembling all over
When the cold wind blows, the muscles of the whole body will tighten. The cold receptor is stimulated and introduced into the thermoregulatory center, which will cause involuntary rhythmic contraction of skeletal muscle, with the aim of transforming mechanical energy into heat energy and relieving cold. This is medically called "chill fever". Stamping your feet in the cold wind is also an instinctive reaction based on this principle.
2. Cold body ends
When the outside temperature is too low, more blood will flow to the center of the body, providing oxygen and nutrition for important organs, and peripheral parts such as fingers, toes and ears will feel cold because of reduced blood flow. So wear earmuffs when you go out, or cover your ears and nose with a wide hat scarf; Wear thick socks, warm shoes and gloves; Wearing warm clothes on the chest and back helps to make the blood flow evenly distributed and ensure the blood supply in the peripheral parts of the body. Old people, children and other weak people should pay special attention to keeping their limbs warm. Enter the warm room from the outside, rub your hands first, and then rub your ears to warm them up quickly. Not suitable for direct application with hot water or hot objects.
Step 3 clean your nose
Normal people secrete hundreds of milliliters of nasal mucus every day, which will flow along the direction of nasal mucosa cilia movement, to the back nostril and then to the pharynx, and some of them will evaporate or dry up, so there will be no nasal mucus flowing down at ordinary times. However, when cold air enters the nasal cavity, the capillaries contract and the cilia movement is weakened, and there will be a phenomenon of clearing nose or nose. This is a self-protection reflex that the nose is sensitive to cold air. Wearing a mask when going out in cold weather can reduce the chance of cold air entering the nasal cavity. Washing your face with cold water once a day can enhance your adaptability to the cold. When you have a runny nose, you can wash your nose with warm salt water and massage your nose. If there is a little cold air, your nose will run, and it will last for a long time, and it will not get better indoors. If it is suspected that it is caused by rhinitis, it is recommended to go to the hospital.
4. Increase the burden on the heart
In cold weather, in order to supply energy to the body, the heart rate will increase, and the oxygen consumption and workload of the heart will also increase. At low temperature, the blood is thicker and the flow rate is slower, which further increases the burden on the heart. Once stimulated by cold, coronary artery tends to contract and spasm, and blood pressure rises. Patients with original cardiovascular diseases may have acute myocardial ischemia, induce angina pectoris and even myocardial infarction.
In order to reduce the risk, the suggestions are as follows: First, raise the temperature of the bathroom before bathing to avoid cold stimulation; Soak your feet with hot water before going to bed to promote blood circulation. Second, drink more water, eat more fruits and vegetables, eat less big fish and meat, reduce blood viscosity and avoid thrombosis. Third, pay attention to the details of life, such as slow down when the position changes, not get up quickly. Fourth, pay attention to the warning signs of "cold" heart. If you suddenly feel pain or oppression in your left chest when you are tired; Suddenly I feel flustered, my eyes are black, and I feel like I'm going to fall; Shortness of breath, prolonged breathing or inability to breathe; Wake up suddenly when sleeping, chest tightness, poor breathing, etc.
5: Shortness of breath
Walking against the cold wind sometimes leads to panting, coughing and nausea. Ni Dongmei said that this is because cold and dry air can dry the nose, stimulate the throat, contract the small trachea, and produce respiratory pressure. When you go out in winter, you should protect your mouth and pharynx and try to breathe through your nose to avoid cold air. Usually pay attention to hydration, not less than seven or eight cups a day, honey water has the effect of moistening dryness; Eat more lungs-moistening foods such as pears, tremella and lilies; You can use a humidifier at home to keep the humidity constant.
6. Frequent urination and excessive urine output
Everyone's water consumption does not change much in the four seasons. In winter, sweat evaporation decreases, and urine output will increase accordingly. Cold can also stimulate the nerve center, cause the adjustment and change of endocrine system, and increase the amount of urination. In order to keep out the cold, most organs, including the bladder, will contract, making it easier to urinate frequently. Avoid getting cold in the waist and abdomen in winter; Ensure adequate drinking water, increase during the day and decrease at night, to prevent frequent getting up at night from affecting sleep. Don't hold your urine at ordinary times, so as not to damage organs such as bladder and prostate.
7: The stomach shrinks into a ball.
When you catch a cold, the muscles and blood vessels in your stomach will contract, and there will be stomach cramps, just like cramps. If you eat raw and cold food or big fish and meat that are difficult to digest at this time, it is more likely to bring a burden to the stomach. Therefore, we must keep the stomach warm in winter. Wear less short clothes, especially clothes that don't show the navel; Eat more warm and digestible foods, such as hot porridge, hot soup, stew, etc. , but meat should not be eaten more; Regularly quantify three meals to keep the stomach in a regular gastric acid secretion cycle. Need to be reminded that although eating hot pot and mala Tang in winter can warm up, it is not advisable to eat more, otherwise it will induce digestive tract ulcers.
8: Stiff joints
Cold can lead to muscle contraction, reduced blood supply and synovial fluid secretion, and poor compliance of tissues around joints (including muscles and ligaments), so many people will feel muscle pain, joint stiffness and arthritis pain. When the temperature drops suddenly, everyone must add clothes to keep warm in time and avoid staying outdoors for a long time. Mountaineering, climbing stairs and other sports will increase joint load and are not suitable for winter. If you want to exercise, you must warm up well to avoid stiff limbs injury after strenuous exercise. Pay attention to calcium supplementation, vitamins and protein in diet. And eat more milk, bean products, shrimp skin, kelp, walnuts and so on.
9. feel depressed
Some people will be depressed, have no energy and get angry easily in winter, which is called "seasonal emotional disorder". In winter, the short sunshine time and the disorder of melatonin (a hormone that controls the rhythm of sleep and waking) make the serotonin content that can produce "pleasure" change. In cold weather, people's activities and social activities are reduced, which will also bring depression. When the sun is shining in winter, go out to bask in the sun; When it is not too cold, strengthening outdoor exercise is very helpful to drive away depression. If the lights at home are changed to warm colors, it will help to improve your mood.
2. How to maintain health in winter?
1. Keep warm: In winter health knowledge, keeping warm is the key to ensuring health. First of all, we should pay attention to dressing, increase clothes in time, and pay attention to keeping warm. Secondly, we should pay attention to the warmth of the feet, because the cold comes from the soles of the feet, and most of the cold outside invades the body from the feet with rich acupoints. It is very important to keep your feet warm.
2. Abstinence: winter corresponds to kidney water. Kidney storing essence is the foundation of storing essence. Kidney essence is related to the whole process of human life growth, development and reproduction. Kidney governs bone, produces marrow, and the marrow is connected with the brain, which is related to the function of the human brain. Keeping in good health in winter should conform to nature, and the most important thing is to store essence. The preservation of kidney essence is mainly abstinence, reducing sexual intercourse and avoiding excessive sexual intercourse. In addition, proper qigong guidance can tonify kidney and store essence, so you may wish to practice more.
3. Get more sunshine: In winter, the yang is restrained, and the outside yang is not prosperous. More sunshine is a natural therapy to regulate seven emotions and overcome bad emotions. Sunlight can dispel the haze, bathed in warm sunshine, the mood will naturally be cheerful, and the bad mood will be eliminated. Seeking a quiet state of mind in winter can make you feel refreshed. The results of modern medical research prove that more sun exposure can promote the absorption of calcium, thus strengthening bones, which is also the only way to store essence.
4. Go to bed early and get up late: according to the health care points to be hidden in winter, it is most suitable to live in a secret room, keep warm clothes, adjust diet and adapt to the cold temperature. Go to bed early and get up late to avoid frost. Going to bed early and getting up late, one can avoid more contact with the outside world, thus avoiding the invasion of the cold outside, and the other can preserve sperm. This way of working and sleeping reduces a lot of activities and consumption. In addition, food and clothing are well maintained, just in line with the requirements of hiding in winter.
5. It is not advisable to take a bath frequently: when the yang is restrained, if you are forced by soup and fire, you will definitely sweat. Chinese medicine believes that sweat is the fluid of the heart, which belongs to the vaginal fluid in the human body and cannot be damaged at will. Sweating too much or too much is easy to damage vaginal fluid, which is not in line with the key points of winter health preservation. Yang will be dissipated with vaginal fluid, leading to the decline of human immune function, thinning of flesh and blood, easy injury, and many diseases caused by exogenous factors.
3, winter health precautions
1 Pay attention to drink plenty of water.
It is necessary to replenish the water lost in summer, and it is very dry in autumn and winter, and a lot of water evaporates through the skin every day, so it is essential to replenish water. I suggest you drink water according to your daily activity. In general, drink at least 8~ 10 glasses of water every day, and don't drink too much water to avoid adverse effects.
Step 2 eat healthily
Diet is mainly nourishing yin and moistening lung. Old people and people with relatively weak stomachs can drink porridge for breakfast, such as lily lotus seed porridge, tremella rock sugar glutinous rice porridge, almond fritillary bulb glutinous rice porridge, black sesame porridge and so on. In addition, we should eat more sour fruits and vegetables and less spicy food, which is of great benefit to protecting the liver and benefiting the lungs.
3, pay attention to keep warm
The climate in autumn and winter is cold, so we should pay attention to keep warm, and we must not be elegant or warm, so as not to catch a cold and get sick. The best way is to do some physical exercises, such as morning exercises and jogging, to improve the resistance to diseases.
