Nowadays, winter travel is becoming fashionable. However, if you do not pay attention to the change of weather during the journey, especially the impact of cold climate on the human body, you may be affected by some diseases. Among the tourists, some are from the south to the north, some are more outdoor activities, and some are the elderly and infirmities, who especially need protection from cold and cold.
Winter in the outdoor travel, the human body exposed parts or terminal parts such as fingers, toes, ears, cheeks of the skin for a long time by cold and damp stimulation, may appear on the skin erythema and accompanied by abnormal feeling, serious can develop into blisters, ulcers. If you stay in a cold environment for too long, not only can skin damage occur, but also may cause systemic disease. In a cold environment, the incidence of heart disease, stroke, flu, chilblain, arthritis and other diseases will increase significantly. In winter tourism, low temperature and humidity, high pressure, wind speed is very common weather. Data show that a sudden drop in temperature or sudden arrival in a cold environment often induces coronary heart disease, stroke and other cardiovascular and cerebrovascular diseases. When the temperature drops from above zero to below zero, there will be a sudden increase in the number of colds in the short term, including many young people. Chronic bronchitis may also recur in cold, dry climates.
To prevent frostbite, it's important to keep your clothes warm. The outermost layer of clothing should be windproof, optional wool, fur or leather clothing; A relatively non-flowing air layer can be formed inside the down jacket, which has good warmth retention and is the preferred clothing for winter tourism. Underwear to soft, moisture absorption, breathable, in order to protect moisture, dry. To minimize skin exposure, it is necessary to regularly exercise or massage the parts prone to chilblain.
If you want to travel in winter without being hurt by the cold climate, it is essential to enhance their ability to prevent cold. Adjust diet, increase body metabolism, is an effective way to improve body heat production capacity. In fact, in order to maintain the body temperature in a cold environment, it is necessary to increase metabolism, and travel consumes a lot of physical strength. Only by increasing the intake of nutrients can the human body meet its needs. In the diet of winter tourists, the intake of three major nutrients, including protein, carbohydrate and fat, as well as minerals and vitamins, should be more than usual, and the intake of fat and carbohydrate should not be overemphasized as usual. Lean meat, eggs, fresh fish, soy products, animal liver to supplement the body heat is very good, can be appropriate to eat more. In addition, we should correct the wrong idea of drinking to keep warm. Alcohol and water cannot produce heat, contrary, alcohol can stimulate the blood vessel of body surface, make body surface blood circulation increases, the person feels "calorific", actually the human body is losing heat.
People suffering from coronary heart disease, arteriosclerosis, hypertension, chronic bronchitis, from health factors, should not travel in the cold winter season, encountered wind, fog, snow and other bad weather, the weak should not go out to travel, otherwise the loss outweighs the gain.
