Are you too old to shovel snow? Experts reveal the hidden heart risks
After 25 years as a heart surgeon in Georgia, Dr. Jeremy London breaks down the specific things people should avoid to prevent cardiovascular disease
TL;DR
- Shoveling snow can push the heart to about 97% of its maximum rate after just 10 minutes.
- Cold air exposure increases blood pressure and reduces coronary blood flow.
- Individuals over 45, especially those with heart disease risk factors, should exercise caution.
- People over 65 with risk factors like high blood pressure, high cholesterol, diabetes, or a sedentary lifestyle are advised to be very cautious.
- Those with a history of heart attack or stroke, or who have undergone bypass surgery or angioplasty, should avoid shoveling snow.
- The exertion of shoveling snow can be similar to or exceed a cardiac stress test.
- Cold temperatures cause blood vessels to constrict, spiking blood pressure and taxing the heart.
- Cold exposure accounts for nearly twice as many cardiovascular deaths as heat exposure.
- Recommendations for shoveling include pacing oneself and using a pushing or sweeping motion.
- Covering extremities, wearing a hat and gloves, and using caution in windy conditions are advised for cold protection.
- Using a snow blower can still raise heart rate, though less than shoveling.
- Warning signs of a potential cardiac issue include chest pain, shortness of breath, racing heart, or palpitations.
