Seniors Beware: Risk Of Heart Attack Increases In Winter
Risk Of Heart Attack Increases In Winter:
53% more heart attacks in winter than summer
As if winter weather wasn’t dangerous enough already, with its slippery and frigid conditions, there’s another reason to be concerned when the mercury in the thermometer drops: winter is the most common season for heart attacks.
Research shows there are up to 53 percent more heart attacks in winter than summer, and twice as many heart attacks a day in January compared to July. And winter heart attacks in winter tend to be more serious with a 9% fatality rate. Research also suggests that winter heart attacks produce more damage to cardiac muscle than those in any other season. But why?
In the cold, blood vessels constrict to help conserve body heat. Narrowed vessels mean higher blood pressure and reduced oxygen supply to the heart, which puts additional strain on the heart. Studies also show that cholesterol levels peak in the winter months. The greatest risk of heart attack is within two weeks of cold-weather exposure, and those who are aged 75-84, along with those with coronary heart disease, are most vulnerable to the temperature changes.
In colder climates, people also tend to exercise less when temperatures dip and where snow and ice are common. Another weather related problem: snow shoveling. Snow shoveling is heavy exercise that can tax the heart of those who aren’t normally active.
There’s also the issue of hypothermia, which occurs when the body temperature falls below normal. Heart failure is the leading cause of death in hypothermia cases, which is why it’s very important to dress appropriately for the weather if you plan to be outdoors in the cold.
Besides cold temperatures, high winds, snow and rain also can steal body heat. Wind is especially dangerous, because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 30-mile per hour wind, the cooling effect is equal to 15 degrees Fahrenheit. Similarly, dampness causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear layers of clothing. This traps air between layers, forming a protective insulation. Also, wear a hat or head scarf. Heat can be lost through your head. And ears are especially prone to frostbite. Keep your hands and feet warm, too, as they tend to lose heat rapidly. Most importantly, remember your heart. It may not feel cold, so you may not think about it, but it is affected just as much by winter weather as the rest of your body.
