When Cold Weather Strikes: Remember These 4 Tips to Protect Your Heart

Recently, temperatures have dropped significantly, and the widening gap between daytime and nighttime temperatures has increased the strain on the cardiovascular system. Sudden temperature drops or cold and damp weather can cause blood vessels to constrict and blood pressure to rise, increasing the risk of acute myocardial infarction and stroke. The Health Promotion Administration reminds the public that people with the “three highs” (high blood pressure, high blood sugar, and high cholesterol), those with cardiovascular diseases, and older adults should be especially vigilant about staying warm during winter. Adopting proper preventive measures is key to reducing health risks associated with low temperatures.

Staying Warm When Going Out: Four Tips to Protect the Heart and Brain

According to the Ministry of Health and Welfare’s 2024 (Year 113) statistics on causes of death in Taiwan, heart disease and cerebrovascular disease ranked second and fourth respectively, claiming approximately 36,000 lives each year. In response to cold weather, the Health Promotion Administration advises the public to follow the four measures below to reduce the risk of myocardial infarction and stroke:

1. Avoid Going Out During the Coldest Hours:

Early morning and evening are typically the coldest times of the day. It is recommended to avoid going out during periods of low temperatures or large temperature fluctuations. If you must go out, travel with family or friends so you can look after one another.

2. Dress Properly to Stay Warm:

Adjust your clothing according to the temperature. Pay special attention to keeping your head, neck, and extremities warm, while ensuring your clothing allows for ease of movement.

3. Do Not Overlook Hydration with Warm Water:

Even in cold weather, the body continues to lose fluids. Insufficient hydration can cause blood to become more viscous, increasing cardiovascular strain. When going out or exercising, it is recommended to drink 200–300 milliliters of warm water every 15 minutes, and to avoid sugary drinks, caffeinated beverages, or alcohol.

4. Watch for Warning Signs of Heart Attack or Stroke:

Seek immediate medical attention if symptoms such as chest tightness or pain, palpitations, shortness of breath, nausea, cold sweats, dizziness, or fainting occur. In addition, stroke warning signs include difficulty performing any of the following actions: smiling, raising both arms, or clearly saying “hello.” Prompt medical care during the golden treatment window is critical.

The general public should remain alert to cold weather warnings, while high-risk groups must be especially vigilant and not underestimate the impact of low temperatures on cardiovascular health. The Health Promotion Administration reminds individuals with the “three highs” (high blood pressure, high blood sugar, and high cholesterol) and those at high risk of cardiovascular and cerebrovascular disease to take medications regularly, avoid stopping medication without medical advice, closely monitor temperature changes, and consistently follow these four protective measures—staying warm and practicing self-monitoring during periods of low temperatures and large temperature fluctuations—to reduce the risk of cardiovascular and cerebrovascular events.
