During the Spring Festival holiday, ice and snow tourism has become the best choice for many people to spend their holidays and leisure. How to protect yourself from freezing when doing outdoor activities in cold regions? What should I do if I have frostbite and hypothermia? Here's a list of "antifreeze tips".
Chen Lixia, director of the medical department of Beijing, said that in cold weather, in order to maintain the internal temperature of the body (that is, the core body temperature), the human body will reduce the blood circulation of the face and limbs, and the ** and tissues in these areas are therefore at risk of frostbite. If hypothermia occurs for a long time, the core body temperature drops, and the brain and vital organs cannot work properly, and life may be threatened.
How to dress to better combat the cold? Chen Lixia said that the inner layer of clothing is best made of lightweight wool, polyester fiber, polypropylene and other fabrics, which are conducive to sweat discharge; Middle-layer clothing is mainly heat preservation, polar down, wool, polyester, down, microfiber, etc. are all good choices; It's best to keep the outer layer of clothing breathable and protected from wind and rain, as non-breathable materials can accumulate sweat and feel colder. In addition, hats, wool socks, and boots can be used to protect the face, hands and feet.
People need food and fluids to fuel their bodies and maintain their body temperature, which is especially important in cold environments. Chen Lixia said that when skiing, hiking and other activities, you should bring foods rich in protein and fat, pay attention to hydration, but control the intake of alcohol, because alcoholic beverages will dilate blood vessels and accelerate body temperature loss.
What to do when frostbite and hypothermia occur? According to experts, you should stay away from the cold environment as soon as possible, take off wet clothes and increase warm clothing, put your hands under your armpits or pat your nose, ears and face with warm palms, and supplement foods with high carbohydrate content and hot water.
Be careful not to rub the frostbitten area, which can cause more serious problems. Chen Lixia said that it is more important to maintain core body temperature, such as the temperature of the chest, neck, heart area and groin area, "If this effect is not good, or the body temperature is lower than 35, you should call ** for help in time." ”
Experts warn that the elderly and children are more likely to suffer from hypothermia and should be better prepared before going out. Some medications, such as cold medicines and receptor blockers, can also affect body temperature, so you should talk to your doctor before starting to take them if you are about to cool down or have plans to go to a cold place.
