The American Heart Association offers winter weather tips to keep people safe this winter from cold weather dangers like hypothermia and heart attacks that may occur as you exert more energy while shoveling snow.
The American Heart Association says that for most people, shoveling snow may not lead to any health problems. However, the association warns that the risk of a heart attack during snow shoveling may increase for some, stating that the combination of colder temperatures and physical exertion increases the workload on the heart.
People who are outdoors in cold weather should avoid sudden exertion, like lifting a heavy shovel full of snow. Even walking through heavy, wet snow or snow drifts can strain a person’s heart. It’s important to know how cold weather can affect your heart, especially if you have cardiovascular disease.
To help make snow removal safer, the American Heart Association has compiled a list of practical tips:
1. Give yourself a break.
Take frequent rest breaks during shoveling so you don’t overstress your heart. Pay attention to how your body feels during those breaks.
2. Be aware of the dangers of hypothermia.
Heart failure causes most deaths in hypothermia. To prevent hypothermia, dress in layers of warm clothing, which traps air between layers forming a protective insulation. Wear a hat because much of your body’s heat can be lost through your head.
Many people aren't conditioned to the physical stress of outdoor activities and don't know the dangers of being outdoors in cold weather. Hypothermia means the body temperature has fallen below 95 degrees Fahrenheit. It occurs when your body can't produce enough energy to keep the internal body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia. Symptoms include lack of coordination, mental confusion, slowed reactions, shivering and sleepiness.
3. Don’t eat a heavy meal prior or soon after shoveling.
Eating a large meal can put an extra load on your heart.
4. Use a small shovel or consider a snow thrower.
The act of lifting heavy snow can raise blood pressure acutely during the lift. It is safer to lift smaller amounts more times, than to lug a few huge shovelfuls of snow. When possible, simply push the snow.
5. Learn the heart attack warning signs and listen to your body, but remember this:
Even if you’re not sure it’s a heart attack, have it checked out (tell a doctor about your symptoms). Minutes matter! Fast action can save lives — maybe your own. Don’t wait more than five minutes to call 9-1-1.
6. Don’t drink alcoholic beverages before or immediately after shoveling.
Alcohol may increase a person’s sensation of warmth and may cause them to underestimate the extra strain their body is under in the cold.
7. Consult a doctor.
If you have a medical condition, don’t exercise on a regular basis or are middle aged or older, meet with your doctor prior to the first anticipated snowfall.
Heart Attack Warning Signs
Some heart attacks are sudden and intense — the “movie heart attack,” where no one doubts what’s happening. But most heart attacks start slowly, with mild pain or discomfort. Often people affected aren’t sure what’s wrong and wait too long before getting help. Here are signs that can mean a heart attack is happening:
- Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.
- Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.
- Shortness of breath with or without chest discomfort.
- Other signs may include breaking out in a cold sweat, nausea or lightheadedness.
As with men, women’s most common heart attack symptom is chest pain or discomfort. But women are somewhat more likely than men to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting, and back or jaw pain.
Calling 9-1-1 is almost always the fastest way to get lifesaving treatment. Emergency medical services staff can begin treatment when they arrive — up to an hour sooner than if someone gets to the hospital by car. EMS staff is also trained to revive someone whose heart has stopped. Patients with chest pain who arrive by ambulance usually receive faster treatment at the hospital, too. It is best to call EMS for rapid transport to the emergency room. If you can’t access EMS, have someone drive you to the hospital right away. If you’re the one having symptoms, don’t drive yourself, unless you have absolutely no other option.
