How Cold Hurts the Heart
With winter on its way, it’s important to know how cold weather can affect your health—in particular your heart. A 16-year study of more than 280,000 patients, reported on ScienceDaily, found that heart attack incidence peaks in winter, which may be due to colder temperatures or changes in behaviour. According to the American Heart Association, keeping warm can help protect your heart. Cold weather steals body heat, which means the body has to fight harder to keep its core temperature warm enough. This is particularly important for the elderly, who may have less body fat and a diminished ability to sense temperature, and people with cardiovascular disease. Here are the potential risks of cold weather, and what you can do to reduce their impact on your heart.
