A winter wonderland may be beautiful, but snow, ice and frigid temperatures can be dangerous. Here are our top four tips to protect yourself when you venture outdoors.
- Bundle up in warm layers (it provides better insulation) and cover everything. Your fingers and toes are at risk for frostbite in extreme cold due to the shunting of body heat to your core to protect your main organs. It is very important to wear waterproof mittens (they keep your fingers warmer than gloves) and layered socks.
- Wear waterproof boots to keep your feet warm and dry. Make sure you have room to wiggle your toes and keep the circulation moving in your feet. If you step in a pile of snow and it seeps into your boot, get inside and dry off as soon as possible. Remaining outside to, say, shovel snow and clear out your driveway can put you at risk for frostbite.
- Wear a warm hat that covers your forehead and ears. We lose at least 10% of our body heat from our head and face. The tip of the nose and the ears are particularly vulnerable to frostbite. Wear a protective, warm facemask.
- Stay hydrated and avoid overexertion. The body uses lots of energy to stay warm. Overexertion will cause the body to sweat and lose more heat.
Can shoveling snow cause a heart attack?
Unfortunately, shoveling snow can cause cardiac arrest or a heart attack due to complicated factors like undiagnosed cardiovascular disease. People who are most vulnerable to the cold include the elderly and those with chronic diseases such as diabetes and heart disease. Additionally, those who abuse alcohol and drugs are less able to handle the cold and may show poor judgment when it comes to staying warm outside.
What is frostbite?
Frostbite, a freezing of the skin tissue, starts with stinging or tingling of the area affected. This is followed by numbness. Body parts that develop frostbite will turn white and appear waxy. Frostbite is not something to be ignored. It can lead to permanent damage to the blood vessels, muscles, tendons and nerves.
When the body temperature drops shivering occurs. If the body temperature continues to fall confusion will set in and is often accompanied by drowsiness.
What do you do about frostbite and hypothermia?
If you think that you or someone you know may be suffering from problems related to cold such as frostbite or hypothermia (a dangerous drop in body temperature as a result of prolonged exposure to cold temperatures), seek medical help immediately. If you are unable to get to a medical facility get into a warm area as soon as possible. Avoid walking on frostbitten feet. Soak the affected areas in warm, not hot water. You can also use body heat (from somewhere like an armpit) to warm fingers. It is important not to massage or rub the frostbitten area since it will cause further damage.
