Winter respiratory tract infection hotspots
With the onset of winter, the risk of respiratory infections gradually increases. Cold weather, dry air, and people congregating indoors all make it easier for the virus to spread. As a family doctor, I'm going to share some simple and easy ways to help you and your family prevent respiratory infections during the winter months.
Handwashing is the first line of defense against infection. During the winter months, influenza viruses and other respiratory pathogens are more active in the air. Be sure to get into the Xi of washing your hands frequently, especially after touching public places and transportation, and use alcohol-based hand sanitizer or soap to wash them adequately.
The air is dry in winter, which makes the mucous membranes of the respiratory tract more susceptible to viruses. By using a humidifier, especially when heating indoors, proper humidity can be maintained, reducing the risk of infection. Clean your humidifier regularly to prevent bacteria from growing.
Cold weather makes people more susceptible to colds. Choose appropriate clothing, especially for the head, neck and feet, to reduce heat loss. Avoid prolonged exposure to cold climates and wear hats, scarves, and warm shoes and socks to keep your whole body warm.
A nutritious and balanced diet helps to strengthen the immune system and improve resistance to viruses. Eat foods rich in vitamin C, vitamin D, and zinc, such as citrus fruits, fish, nuts, etc. Maintaining proper water intake is also beneficial for the health of the mucous membranes of the respiratory tract.
Moderate exercise can help improve the function of the immune system and reduce the risk of infection. Choose outdoor activities and get some fresh air, but make sure you do it at the right temperature. If the weather is inclementary, you can also choose to do moderate exercise indoors.
Despite being cold outside, regular ventilation is an important means of keeping indoor air fresh. Open windows to let fresh air into your home and remove potential airborne viruses and bacteria.
If you are close to someone with an infectious disease, try to avoid close contact, use a mask and wash your hands frequently to reduce the risk of transmission. Especially in public places, try to avoid being too close to people with significant respiratory symptoms.
Regular vaccinations against some common respiratory infections, such as the flu, are a very effective way to prevent them. Talk to your GP about the vaccine schedule that's right for you and your family.
By taking a series of simple and practical precautions, we can reduce the risk of respiratory infections during the winter months. Maintaining good hygiene Xi, keeping indoor and outdoor air fresh, keeping warm and eating a healthy diet are all key to maintaining respiratory health. When it comes to preventing infection, every small effort can be a powerful protective barrier during the cold season.
