In the United States, temperatures have already reached record-breaking levels in which some cities have already reported being colder than parts of the Antarctic. In the Midwest, at least nine people died due to the extreme weather, which shows the dangers brought by the polar vortex.
To stay safe and warm, here are some tips to do during cold weather, according to Medical Daily.
Avoid doing too much physical activity
Reports have already stated the number of heart attack cases increase during the holiday season. Although there are several factors that contribute to this, doing strenuous activities such as shoveling snow can be the major source of sudden stress which could place a lot of stress on the heart in colder weather.
Cold air can be really drying, so you tend to be dehydrated while doing any physical activities on very low temperatures. Remember to drink enough fluid and avoid doing outdoor activities for a while. Additionally, those who have respiratory issues, diabetes, as well as heart failure should speak to their doctors for additional precautions.
Avoid cigarettes and alcohol
Smokers are reportedly prone to frostbite because their blood vessels don't expand quickly enough to provide warmth to different parts of the body. A study conducted by the researchers from Yale University suggested nicotine could slow down the body's normal response to cold.
Meanwhile, drinking alcohol amid cold weather isn't a good idea as well. While you feel warm after a drink, alcohol can actually lower the core temperature and could affect healthy reflexes like the ability to shiver.
Deal with possible frostbite
Frostbite is a condition wherein the skin and other tissues freeze due to extremely low temperatures. The condition usually starts with numbness and then the skin will eventually turn white or blue. So, if you think you're having possible frostbite, deal with it and keep that particular area covered.
Dr. Randall Wexler, a professor at Ohio State University, noted do not rub your hands if you have frostbite because it might cause tissue damage.
Wear the right kind of clothing
When temperatures are extremely low, don't opt for one thick coat. Rather, wear multiple layers to help preserve your core. But, make sure these layers are loose since tight clothing reduces circulation. As for the materials of the clothing, choose wool or synthetics like polypropylene, microfiber, polyethylene, and polyester. For footwear, opt for insulated shoes that are slip-proof to be safe while walking on icy and slippery surfaces.
