How to fully protect your body outdoors

Nowadays, winter tourism is becoming a fashion. However, if you do not pay attention to weather changes during your trip, especially the impact of cold weather on the human body, you may be attacked by certain diseases. Among the tourists, some are traveling from the south to the north, some do a lot of outdoor activities, and some are elderly and infirm. These people especially need to protect themselves from the cold and frostbite.

Cold and frost protection:

When traveling outdoors in winter, the skin on exposed parts of the human body or extremities (such as fingers, toes, and cheeks) is exposed to cold and humidity for a long time, which may cause erythema on the skin accompanied by abnormal sensations, and in severe cases may develop into blisters and 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, influenza, frostbite, and arthritis will increase significantly. When traveling in winter, low temperature and humidity, high air pressure and high wind speed are common. When the temperature drops from above zero to below zero, the number of people catching colds will increase sharply in a short period of time, including many young people. Chronic bronchitis may also recur in cold, dry climates.

To prevent frostbite, it is important to wear warm clothing. The outermost layer of clothing should be windproof, and can be made of woolen, fur or leather. Down jackets can form a relatively stagnant air layer inside, which has good warmth retention and is the preferred clothing for winter travel.

Underwear should be soft, moisture-absorbent and breathable to facilitate moisturizing and drying. Try to minimize exposed skin areas, and for areas prone to frostbite, it is necessary to move or massage them frequently.

In order to avoid being harmed by the cold climate when traveling in winter, it is essential to enhance your own ability to resist the cold. Adjusting diet and increasing body metabolism is an effective way to improve the body's ability to produce heat. In fact, in order to maintain body temperature in a cold environment, the human body must increase metabolism. In addition, traveling consumes a lot of physical energy. Only by increasing the intake of nutrients can the body's needs be met.

In the winter tourists' diet, the intake of the three major nutrients, protein, carbohydrates and fat, as well as minerals and vitamins should be higher than usual. As usual, we should not overemphasize limiting the intake of fat and carbohydrates. Lean meat, eggs, fresh fish, soy products, and animal liver are very good for replenishing human body calories and can be eaten more appropriately. In addition, we need to correct the misconception that drinking alcohol can keep you warm. Alcohol and water cannot produce heat. On the contrary, alcohol can stimulate the blood vessels on the surface of the body, increasing blood circulation on the surface of the body, making people feel "fever", but in fact the body is losing heat.
