Winter Storm Precautions: Heart Health and Snow Shoveling Risks
As a significant winter storm approaches this weekend, health experts are urging caution, especially for older individuals, regarding the risks associated with shoveling snow.
A recent review from the Mayo Clinic highlighted that a mere 10 minutes of vigorous snow shoveling can elevate heart rates to approximately 97% of their maximum. Furthermore, cold air can raise blood pressure and restrict blood flow to the heart.
While there isn’t a specific age defined as “too old” for shoveling, many doctors advise those over 45 to be extra careful to prevent heart-related incidents.
Who Should Be Careful
Dr. Navjot Kaur Sobti, a cardiologist in New York, states that people in their mid-40s and older should tread lightly, especially if they do not regularly exercise. “For those over 65 or with conditions like high blood pressure, diabetes, or obesity, we recommend being particularly cautious,” she advised.
Dr. John Osborne, a cardiologist in Texas, echoed this sentiment, especially for men over 65. He emphasized that if someone isn’t in good cardiovascular shape, it might be wise to seek assistance instead of shoveling alone.
The Dangers of Shoveling
Cardiovascular episodes can occur, particularly among those who lead mostly sedentary lifestyles. Dr. Osborne noted a common pattern: individuals who spend most of their day sitting might attempt heavy shoveling after a fresh snowfall, leading to potential pitfalls.
Dr. Sobti explained that shoveling snow can stress the heart similarly to a cardiac stress test, potentially even exceeding it. The cold can further constrict blood vessels and heighten blood pressure, making shoveling even riskier.
Recent studies reveal that exposure to cold can lead to almost double the number of cardiovascular-related deaths compared to heat. Older adults are particularly vulnerable to this risk.
Tips for Safer Shoveling
To minimize risks if shoveling is necessary, it’s best to ask for help. If you decide to shovel, be sure to pace yourself and employ a sweeping motion rather than heavy lifting. Cover your mouth and nose, wear appropriate clothing, and exercise extra caution in windy conditions.
Automated snow blowers can also elevate heart rates, although they usually raise them to about 120 beats per minute, compared to 170 for traditional shoveling, according to the American Heart Association.
Watch for Warning Signs
Dr. Sobti emphasizes the importance of being alert to symptoms while shoveling. If anyone experiences chest pain, shortness of breath, or a racing heart, they should stop immediately. Even if such symptoms fade away quickly, it’s vital to seek medical attention. “It’s better to be safe than sorry,” she advises.
As the storm looms, taking these precautions can help keep everyone safe while navigating the tasks of winter.
