Nowadays, winter tourism is becoming fashionable. However, if you do not pay attention to the changes in the weather during the journey, especially the impact of cold weather on the human body, you may be affected by certain diseases. Among the tourists, some are from the south to the north, some outdoor activities are more, and some are old and infirm, these people especially need cold and antifreeze.
When traveling outdoors in winter, the skin of exposed parts or distal parts of the human body (such as fingers, toes, auricles, cheeks) is prolonged by cold and moisture, and erythema may appear on the skin with abnormal feeling, which may develop severely. Blisters, ulcers. If you stay in a cold environment for too long, not only will skin damage occur, but it may also cause systemic diseases. In cold environments, the incidence of diseases such as heart disease, stroke, flu, frostbite, and arthritis will increase significantly. In winter tourism, weather with low temperature and humidity, high air pressure and high wind speed are common. The data show that sudden drop in temperature or sudden arrival in a cold environment often induces cardiovascular and cerebrovascular diseases such as coronary heart disease and stroke. When the temperature drops from zero to below zero, the number of people catching a cold will increase sharply in the short term, including young people. Chronic bronchitis may also recur in a cold, dry climate.
In order to prevent frostbite, it is important to pay attention to the warmth of the clothing. The outermost clothes should be windproof. Choose clothes made of velvet, fur or leather. The down jacket can form a relatively non-flowing air layer. It is very warm and is the clothing of choice for winter travel. Underwear should be soft, hygroscopic and breathable to help moisturize and dry. To minimize the exposed parts of the skin, it is necessary to have regular activities or massage for areas prone to frostbite.
In order to avoid winter weather damage from cold weather, it is essential to enhance your cold resistance. Adjusting diet and increasing body metabolism are an effective way to improve the body’s ability to produce heat. In fact, if the human body needs to maintain body temperature in a cold environment, it must increase metabolism. In addition, it requires a lot of physical strength in tourism. Only by increasing the intake of nutrients can it meet the needs of the human body. In the diet of winter tourists, the intake of three major nutrients, minerals and vitamins of protein, carbohydrate and fat are more than normal, and it is not possible to over-emphasize the restriction of fat and carbohydrate intake as usual. Lean meat, eggs, fresh fish, soy products, and animal liver are good for supplementing human body heat and can be eaten appropriately. In addition, it is necessary to correct the misconception of drinking and heating. Alcohol and water can’t produce heat. On the contrary, alcohol can stimulate blood vessels on the body surface, increase blood circulation on the body surface, and people feel “heat”. In fact, the human body is losing heat.
People with coronary heart disease, arteriosclerosis, hypertension, and chronic bronchitis should not travel in the cold winter season due to health factors. In case of bad weather such as strong winds, heavy fog, heavy snow, etc., the infirm should not go out to travel, otherwise they will not be able to pay for it. .
In a sub-zero temperature environment, the battery of electronic devices such as mobile phones and cameras will be powered down quickly. It is recommended to buy a winter camera cover to keep warm, or carry the phone, camera and spare battery around, and keep warm with body temperature. In many scenic spots in winter, there will be snow and ice on the ground. In addition to wearing non-slip shoes, there is a skill that every time you get off the bus, you must first pay attention to whether there is water or ice under your feet. When you step out, your knees are slightly bent. Keeping the center of gravity forward will greatly reduce the chance of falling. If you want to go to the north to see the snow, don’t be too excited. The snow in the northern part of the country or the snowy weather in some mountains must pay attention to the protection of the eyes. The snow has strong UV reflection, when strong ultraviolet rays enter the snow. After the eyes, photochemical effects occur, which is very harmful to the eyes.
Exercise should be done suitably. Choose the right snow sports and rides based on your physical condition and skill level. Exercise under the guidance of a professional and take protective measures. It is recommended to purchase the corresponding personal accident insurance. Minors must carry out sports corresponding to their age and ability under the care of their guardians. Older people should not experience intense sports such as ice competition and snow sports, especially those with cardiovascular and respiratory diseases should pay attention to the impact of cold weather on the body. In case of physical discomfort, you should seek medical advice promptly.
Take effective measures to prevent slipping. Self-driving tourists should check the vehicle battery, antifreeze, tires, lights and other conditions before the trip, prepare the snow chains, keep the distance during driving, do not brake, turn sharply. Tourists should wear anti-slip shoes during walking, and move forward steadily. When walking on the ice and snow, the knees should be slightly bent and the center of gravity should be tilted forward to prevent falling.
