In December 2024, the National Health Commission issued the latest winter health protection tips, reminding the public to pay attention to the prevention of respiratory diseases such as influenza and pneumonia. Winter is a time of high incidence of respiratory diseases, but most people ignore the potential health threats of some small daily habits. These seemingly trivial actions may be quietly weakening your immunity and even causing serious health problems.
1. Neglecting to wash your hands: an invisible accomplice in the spread of disease
According to data released by the National Health Commission, the transmission rate of infectious diseases in winter is 30% higher than in other seasons. Among them, the hand is an important medium for the spread of germs. You may inadvertently send germs into your body by touching your face or rubbing your eyes.
Case
A 26-year-old office worker, Xiao Wang, was hospitalized with the flu. Doctors found that the source of his infection turned out to be touching his nose without washing his hands. Data shows that up to 40% of winter influenza viruses are transmitted through contact, and simple handwashing can effectively reduce the risk of transmission.
Solution(s):
- Wash your hands thoroughly with running water and soap, especially after eating, coughing, or sneezing.
- Carry hand sanitizer with you when you go out and make sure your hands are always clean.
2. Lazy ventilation: Indoor air is a health threat
In winter, when the weather is cold, many people are accustomed to closing doors and windows to keep warm, but ignore the health hazards of indoor air pollution. Studies have shown that prolonged exposure to confined spaces can lead to increased concentrations of viruses in the air, significantly increasing the risk of infection.
Case
A school in Hebei Province recently broke out of a group of influenza, and nearly 50 students developed fever, cough and other symptoms. The investigation found that the doors and windows of classrooms were closed for long periods of time, which exacerbated the spread of the virus.
Solution(s):
- Open windows for ventilation at least twice a day for 10-15 minutes each time to maintain air circulation.
- Use an air purifier to help improve indoor air quality.
3. Wearing too much: "Keeping warm by mistake" becomes a health enemy
Cold weather makes people involuntarily wear heavy clothing, but overheating can backfire. Experts point out that heavy clothing can lead to hyperthermia, excessive sweating, and reduce the body's ability to adapt to cold environments.
Case
42-year-old Ms. Li wore a three-layer down jacket for herself and her child to keep warm, but the child caused eczema due to covering the heat, and Ms. Li caught a cold due to excessive sweating.
Solution(s):
- Choose the right clothing for the weather, following the principle of "warm but not too hot".
- Choose breathable clothing when exercising outside to prevent you from getting cold after sweating.
4. Preference for heavy flavors: A high-salt diet harms immunity
During the winter tonic season, many people like to eat pickled foods and heavy dishes. However, a high-salt diet can increase the burden on blood pressure, and long-term intake can also suppress the function of immune cells and increase the risk of infection.
Case
According to the 2024 China Nutrition Report, the average salt intake of residents in winter exceeds 1.5 times the recommended daily amount, and a long-term high-salt diet is directly related to an increased risk of colds and chronic diseases.
Solution(s):
- Control your daily salt intake to no more than 5 grams.
- Natural flavors such as lemon juice and vanilla are used instead of some of the salt to reduce the burden on the palate.
5. Lack of attention to vaccination: Weak awareness of prevention
Influenza and pneumonia vaccines are important means of preventing respiratory diseases in winter, but many people neglect to get vaccinated due to lack of awareness or misconceptions, which increases the risk of infection.
Case
A survey for the winter of 2024 shows that about 60% of older adults are not vaccinated against the flu, and nearly half of them think the vaccine is "useless." In fact, vaccination can be effective in reducing infection rates and the risk of severe disease.
Solution(s):
- Get vaccinated against influenza or pneumonia depending on your personal situation, especially in the elderly and people with chronic diseases.
- Get vaccinated information through formal channels and avoid listening to rumors.
Conclusion: Health starts with changing small habits
The health threat of winter comes not only from the sudden drop in temperature, but also from the small habits of our daily lives. From handwashing and ventilation to dressing properly and controlling your diet, every seemingly small change in behavior can lead to significant health gains.
The National Health Commission's reminder is not only a winter health guide, but also a profound reflection on the lifestyle of each of us. What actions will you take to protect your health in the winter of 2024? Feel free to share your winter protection tips in the comments section!
