2024 Winter Health Protection Guide: Five Bad Habits Secretly Weakening Your Immunity

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 high-incidence season for respiratory diseases, yet many people overlook the potential threats to their health posed by some daily habits. These seemingly insignificant actions may be subtly weakening your immunity, even leading to serious health problems. This article will delve into five common bad winter habits and their health hazards, and provide corresponding improvement suggestions to help you better protect your winter health.

I. Neglecting Handwashing: A Silent Accomplice in Disease Transmission

Data released by the National Health Commission shows that the transmission rate of infectious diseases in winter is 30% higher than in other seasons. Hands are a major medium for the transmission of germs; people often unknowingly introduce germs into their bodies by touching their faces or rubbing their eyes. A 26-year-old office worker, Xiao Wang, was hospitalized with influenza; the doctor discovered that his infection source was actually from touching his nose without washing his hands. Data shows that the proportion of influenza virus transmission through contact in winter is as high as 40%, while simple handwashing can effectively reduce the risk of transmission.

Neglecting handwashing undoubtedly opens the door for viruses. The dry and cold environment in winter also easily leads to skin cracking, providing an opportunity for bacterial invasion. Therefore, developing good handwashing habits is crucial.

Solutions:

• Thoroughly wash your hands with running water and soap for at least 30 seconds, especially after eating, coughing, or sneezing. Pay particular attention to cleaning the spaces between fingers and under fingernails, areas where dirt and germs easily accumulate.

• Carry hand sanitizer when going out to ensure that you can clean your hands at any time, especially after touching public facilities. Choose hand sanitizers containing alcohol and pay attention to the amount and method of use.

II. Reluctance to Ventilate: Indoor Air Becomes a Health Threat

In the cold winter weather, many people habitually close windows and doors for heating, but they ignore the health hazards of indoor air pollution. Studies have shown that staying in enclosed spaces for long periods of time can lead to an increase in the concentration of viruses in the air, significantly increasing the risk of infection. A recent outbreak of influenza at a school in Hebei province affected nearly 50 students who presented with fever and coughing; the investigation revealed that the classrooms had been kept closed for extended periods, exacerbating virus transmission.

A confined indoor environment not only breeds bacteria and viruses but also leads to increased carbon dioxide concentration and reduced oxygen content, affecting respiratory health. In addition, allergens such as dust and pet dander in the indoor air can worsen allergic symptoms.

Solutions:

• Open windows for ventilation at least twice a day for 10-15 minutes each time. Persist in this even during the cold winter months. Choose times with good air quality to open windows for ventilation, avoiding hazy weather.

• Use an air purifier to help improve indoor air quality. Choose an air purifier with a HEPA filter and replace the filter regularly.

III. Overdressing: "Incorrect Warmth" Becomes a Health Enemy

Cold weather makes people instinctively put on heavy clothing, but excessive warmth can actually backfire. Experts point out that overly heavy clothing can lead to overheating, excessive sweating, and reduced adaptability to cold environments. 42-year-old Ms. Li dressed herself and her child in three layers of down jackets to keep warm; as a result, her child developed eczema from the heat, and Ms. Li caught a cold from sweating and then getting chilled.

Excessive warmth inhibits the normal secretion of sweat glands, reduces the body's immunity, and makes it easier to contract colds and other respiratory diseases. In addition, excessively thick clothing can also affect blood circulation, making the body feel uncomfortable.

Solutions:

• Choose appropriate clothing according to weather changes, following the principle of "keeping warm but not overheating." Choose clothing with good breathability to avoid stuffiness.

• Choose breathable clothing when exercising outdoors to prevent catching a chill after sweating. Change clothes promptly after exercise to keep your body dry.

IV. Preference for Heavy Flavors: High-Salt Diet Damages Immunity

• During the winter season of tonic, many people like to eat pickled foods and heavily flavored dishes. However, a high-salt diet increases blood pressure burden, and long-term intake can also inhibit the function of immune cells, increasing the risk of infection. The 2024 China Resident Nutrition Report points out that the average daily salt intake of residents in winter exceeds the recommended daily amount by 1.5 times; long-term high-salt diets are directly related to an increased risk of colds and chronic diseases.

A high-salt diet increases the burden on the kidneys, affects the body's normal metabolic functions, lowers immunity, and makes the body more susceptible to viral attack. In addition, a high-salt diet also increases the risk of hypertension and cardiovascular disease.

Solutions:

• Control your daily salt intake to no more than 5 grams. Low-sodium salt can be used to replace ordinary table salt, but intake still needs to be controlled.

• Use natural seasonings such as lemon juice and herbs to replace some of the salt, reducing the burden on taste buds while increasing the deliciousness of food.

V. Failure to Prioritize Vaccination: Weak Preventive Awareness

Influenza and pneumonia vaccines are important means of preventing respiratory diseases in winter, but many people ignore vaccination due to lack of awareness or misconceptions, increasing the risk of infection. A survey conducted in winter 2024 showed that about 60% of the elderly did not receive the influenza vaccine, with nearly half believing that the vaccine was "useless." In fact, vaccination can effectively reduce the infection rate and the risk of severe illness.

Vaccination is one of the most effective ways to prevent respiratory diseases such as influenza and pneumonia, effectively reducing the risk of infection and the severity of illness. Vaccination is particularly important for the elderly, children, and patients with chronic diseases.

Solutions:

• Get vaccinated against influenza or pneumonia according to your individual circumstances, especially for the elderly and those with chronic diseases. Pay attention to vaccination information and choose a regular vaccination institution for vaccination.

• Understand vaccination information through formal channels, avoid listening to rumors, and rationally view vaccination.

Conclusion: Health Starts with Changing Small Habits

The health threats of winter come not only from the sharp drop in temperature but are also hidden in our daily habits. From handwashing and ventilation to dressing appropriately and controlling diet, every seemingly small behavioral change can bring significant health benefits. The reminder from the National Health Commission is not only a winter health guide but also a profound reflection on our individual lifestyles. Let's protect our health this winter 2024 by starting with changing these small habits.
