Protecting Heart Patients from Cold Weather
As winter approaches, heart patients must be especially vigilant about the risks posed by cold temperatures. A recent study highlights that the sensation of cold is influenced more by physical characteristics, such as body fat percentage and size, rather than gender. This is particularly concerning for older adults, who may be at greater risk of hypothermia due to decreased subcutaneous fat and a diminished ability to sense temperature changes.
Individuals with coronary heart disease are particularly susceptible to cold weather, often experiencing angina, or chest pain, when temperatures drop. Joanne Whitmore, a nurse at the British Heart Foundation, emphasizes that cold weather can elevate the risk of heart attacks, strokes, and respiratory infections like the flu.
Julie Ward, another nurse at the British Heart Foundation, explains that cold temperatures cause blood vessels in the skin and extremities to narrow, which conserves heat but increases pressure in the circulatory system. This forces the heart to work harder, raising heart rate and blood pressure. Additionally, cold weather can thicken the blood, increasing the likelihood of clots, which can lead to heart attacks or strokes.
Tips for Heart Health During Winter
To safeguard heart health during the colder months, experts recommend several strategies:
- Dress Warmly: Layering clothing traps air for insulation, and wearing a hat can help retain body heat. A scarf can also warm the air before it reaches the lungs, reducing shock to the body.
- Eat Heart-Healthy Foods: Consuming warm meals rich in fiber and lean protein, such as soups, can be beneficial. Staying hydrated is equally important for maintaining smooth blood flow.
- Exercise Indoors: Gentle indoor exercises can promote blood circulation without straining the heart. Outdoor activities should be approached with caution, especially in freezing conditions.
- Consult Healthcare Providers: Those with existing medical conditions should seek advice before increasing physical activity in cold weather. Recognizing the signs of a heart attack—such as chest discomfort, shortness of breath, and fatigue—is crucial. Immediate medical attention is recommended if any abnormal symptoms occur.
- Learn CPR: Knowing CPR can significantly increase survival chances in cases of sudden cardiac arrest, making it a vital skill for everyone, especially those caring for heart patients.
