Winter's Approach: A Guide to Protecting Elderly Health During the Cold Season Remember the "3 Prevent, 2 Avoid" Principles for Safety

The cold, dry climate of winter not only brings discomfort but also poses a significant threat to the health of the elderly, acting as a leading cause of health issues. Data show a surge in cardiovascular diseases, respiratory infections, and acute exacerbations of chronic illnesses during winter, with individuals over 50 facing particularly high risks. Many elderly individuals, lacking proper winter protection knowledge such as exercising too early in the morning or consuming overly rich diets exacerbate their health problems. Therefore, doctors advise the elderly to remember the "3 Prevent, 2 Avoid" principles: preventing cold exposure and keeping warm, preventing infections, and preventing emergencies; and avoiding exercising on an empty stomach and avoiding greasy food. Through scientific prevention and health management, they can safely navigate the cold winter months. This article will use specific examples and measures to help readers comprehensively understand how to better protect the winter health of the elderly.

I. A Warning from Winter: Lessons from a True Case

Mr. Wang, 55, was a well-known "fitness enthusiast" in his community. He was physically robust and active, exercising almost every morning without fail. Even during the biting cold of winter, he would put on his sportswear and embark on his "health journey" as the sun rose. He firmly believed that morning exercise boosted immunity, a habit he had maintained for many years.

However, one cold winter morning, Mr. Wang's persistence nearly cost him his life. That day, as usual, he woke up at 5:30 AM, dressed in thick sportswear and a woolen hat, and went to the park near his apartment for his morning workout. After jogging three laps around the park, he felt a sharp pain in his chest, as if something were pressing down on him. The pain quickly spread to his left arm. He tried to reach the park exit but his legs gave way, and he collapsed.

Fortunately, a young man passing by promptly called 120 (the emergency number in China) and provided Mr. Wang with basic warmth and first aid. The community doctor who arrived soon after initially diagnosed Mr. Wang with a possible cardiovascular disease.

The ambulance rushed Mr. Wang to the hospital. After emergency interventional surgery to clear his blocked artery, he finally escaped death. Post-surgery, the doctor warned his family that the winter cold significantly impacts the cardiovascular system, and elderly people who exercise outdoors early in the morning are particularly susceptible to such problems. They emphasized the need for warmth and avoiding early morning exercise.

Lying in his hospital bed, Mr. Wang couldn't understand: he had always exercised regularly and eaten a light diet. Why did this happen? Was it simply due to the cold? This case serves as a warning: the impact of winter cold on the health of the elderly cannot be ignored, and scientific protective measures are crucial.

II. The Serious Threats of Winter to Elderly Health

Winter is a high-incidence season for many health problems among the elderly. This is closely related to several factors, including sudden drops in temperature, cold stimulation, and the spread of seasonal viruses. Studies show that people over 50 face a significantly increased risk of cardiovascular diseases, respiratory infections, and acute exacerbations of other chronic illnesses during winter.

1. High Incidence of Cardiovascular Diseases: The Deadly Blow of Cold

Cold is one of the biggest threats to the cardiovascular system of the elderly in winter. In low-temperature environments, the sympathetic nervous system is excited, causing vasoconstriction and increased blood pressure. The elderly have less elastic blood vessel walls and reduced regulatory capacity. Vasoconstriction is more likely to cause blood pressure fluctuations. In winter's low temperatures, the body's metabolic rate increases, but blood flow decreases, making blood clots more likely. If a blood clot blocks a blood vessel, it can lead to serious consequences such as heart attacks and strokes, which explains the high incidence of these events during winter. Furthermore, the elderly often have chronic diseases such as hypertension and hyperlipidemia, which are more easily exacerbated by cold stimulation in winter, further increasing the risk of cardiovascular diseases.

2. Rampant Respiratory Diseases: The Winter Frenzy of Viruses

Winter is a high-incidence season for respiratory diseases. The cold, dry air provides ideal conditions for the spread of viruses. Influenza viruses, coronaviruses, etc., are more active and infectious in low-temperature environments. The elderly have weaker immune systems, significantly increasing their risk of infection. Cold air weakens the barrier function of the respiratory mucosa, making it easier for viruses and bacteria to invade, leading to colds, bronchitis, pneumonia, and other respiratory diseases. Patients with chronic obstructive pulmonary disease (COPD) and asthma should be particularly vigilant in winter, as cold air may trigger acute exacerbations, worsening symptoms and increasing the risk of hospitalization.

3. Exacerbation of Underlying Diseases: The Winter Test for Chronic Illnesses

The third major threat to the health of the elderly in winter is the impact on underlying diseases. Hypertension and diabetes, etc., are more prone to fluctuations in cold environments. Low temperatures can raise blood pressure, and individuals with hypertension, with their weaker regulatory capacity, are more susceptible to cardiovascular diseases. Diabetics may experience blood sugar fluctuations due to metabolic abnormalities and dietary changes in winter, increasing the risk of related complications. In addition, the elderly tend to be less active in winter, yet their diet may shift towards high-calorie, high-fat foods. Increased caloric intake coupled with a lack of exercise easily leads to weight gain, exacerbating obesity and hyperlipidemia, placing a greater burden on existing atherosclerosis and coronary artery disease, and even leading to acute changes.

III. "3 Prevent, 2 Avoid" for Elderly Winter Health Protection

People over 50 should remember the "3 Prevent, 2 Avoid" principles in winter to reduce seasonal health risks:

"3 Prevent": Prevent Cold, Prevent Illness, Prevent Emergencies

• Prevent Cold: Wear multiple layers of breathable clothing, protecting the head, neck, hands, and feet, which are prone to heat loss; maintain an indoor temperature of 18-22, and use a humidifier; reduce outdoor activities in extremely low temperatures, especially in the morning and evening; wear a mask and earmuffs when going out.

• Prevent Infection: Get flu and pneumonia vaccines; wash hands frequently and avoid touching the mouth and nose; wear masks in public places; consume foods rich in vitamins C and D; monitor body temperature and seek medical attention if any abnormalities occur.

• Prevent Emergencies: High-risk individuals for cardiovascular diseases should be vigilant for symptoms such as chest tightness and dizziness; regularly measure blood pressure and blood sugar; take medication on time; avoid strenuous exercise; patients with chronic diseases should strictly follow medical advice; keep emergency medications at home and understand how to use them.

"2 Avoid": Avoid Exercising on an Empty Stomach, Avoid Greasy Food

• Avoid Exercising on an Empty Stomach: In the cold winter mornings, exercising on an empty stomach can lead to hypoglycemia or blood pressure fluctuations, causing dizziness and fainting; exercise should be scheduled for the sunny midday or afternoon, preferably indoors; avoid strenuous exercise and opt for low-intensity activities.

• Avoid Greasy Food: Winter tonics should be balanced, avoiding high-fat, high-cholesterol foods; eat a light diet, consuming plenty of fiber-rich foods and supplementing with adequate amounts of high-quality protein.

IV. Common Winter Health Misconceptions and Precautions

• Hot Baths Are Not Suitable for Everyone: Elderly individuals with unstable blood pressure may experience dizziness or vasodilation from prolonged hot baths; keep the water temperature between 37-40, and limit the duration to no more than 20 minutes; avoid sudden changes in temperature.

• Frozen Air Is Not Necessarily Fresh: Although the air is cool in the winter mornings, cold stimulation increases the burden on the respiratory system; open windows for ventilation should be done during windless, sunny midday periods.

• Staying Up Late Watching TV Leads to Hidden Fatigue: Winter days are short and nights are long; avoid watching TV or using electronic devices for extended periods; maintain a regular sleep schedule to boost immunity.

• Wearing Many Thick Clothes Does Not Equal Scientific Warmth: Elderly individuals should focus on layering in winter, with breathable inner layers and windproof and waterproof outer layers.

V. Comprehensive Recommendations for Winter Health Management

• Regular Check-ups: People over 50 should undergo a comprehensive annual physical examination, monitoring blood pressure, blood sugar, blood lipids, and cardiopulmonary function.

• Establish a Health Record: Create a health record for the elderly, documenting daily health data to respond promptly to abnormalities.

• Psychological Adjustment: Reduced activity in winter can lead to low moods; increase indoor recreational activities to maintain a cheerful disposition.

VI. Conclusion

Winter is a concentrated period of health risks for the elderly. However, by implementing the scientific "3 Prevent, 2 Avoid" measures, they can effectively reduce the risk of illness and safely navigate the cold season. The elderly and their families should be constantly aware of seasonal health risks and take meticulous preventive measures in all aspects of their lives. Only by paying attention to detail and preventing illness can the elderly enjoy a healthy and peaceful winter.
