Scientific studies have shown that the heart rate and blood pressure of healthy men in their 30s who shoveled wet snow for several minutes increased to levels equal to or higher than the maximum level achieved on the treadmill. After just a few minutes, the frequency of contractions in humans became the same as during intense aerobic exercise.
This type of physical activity can be especially dangerous for people who often sit a lot and do not exercise regularly.
Heart attacks due to winter rowing mostly occur in people aged 45 and over with heart disease. Those at increased risk include people who have had a heart attack, had angioplasty or bypass surgery, or experienced chest discomfort during exercise. Other factors that increase your chance of having a heart attack are high blood pressure, high cholesterol, diabetes, obesity and smoking.
Here are some tips on how to handle snow removal to avoid a heart attack or cardiac arrest.
If you need to clear snow, take your time. Take things step by step and don’t try to do too much at once.
Learn common symptoms of heart problems. These include pain or pressure in the chest, dizziness, fast heartbeat, or irregular heart rhythm.
Make someone look at you. This way, if you lose consciousness while clearing snow, this person can quickly call an ambulance.
Cover your nose and mouth. This will help you avoid breathing cold air. Also wear layers of clothing, a hat and gloves.
Push or “sweep” snow. It will require less effort.
Be especially careful in windy weather. It increases the effects of cold on your body.
Use an automatic snow blower. Research shows that it increases heart rate up to 120 beats per minute, and rowing up to 170 beats per minute.
Be active in general.. Walk or do aerobic exercise for 30 minutes several days a week.
If you have or suspect heart disease, ask someone to clear the snow for you. This is especially true for older people.
