Kangbeijing Insight: Why Are People More Prone To Colds And Illness in Frigid Weather?

1. Impairing the physical barrier: The warm mucus and moving cilia lining the respiratory tract act as a natural defense to trap pathogens. Extremely cold, dry air dries out the mucus and slows ciliary movement, disabling this line of defense and letting viruses invade cells easily.

2. Reducing immune surveillance: To preserve core body temperature in the cold, the body temporarily redirects resources, lowering the activity and response speed of peripheral immune cells like macrophages and natural killer cells—weakening the body’s "immune patrol".

3. Altering behaviors and raising exposure risk: People tend to gather for long hours in enclosed, poorly ventilated indoor spaces in bitter cold, which boosts viral transmission via droplets and aerosols. Viruses linger longer in the air, infecting more people.

How to Protect Yourself Scientifically?

• Timed ventilation: Open windows briefly for quick air exchange during the warm noon hours.

• Humidity control: Use a humidifier to keep indoor humidity at 40%-60% to protect the respiratory mucous membrane.

• Active purification: For spaces with high foot traffic or families with vulnerable groups (the elderly, children), use air purifiers with active disinfection functions as an extra defense.

For example, devices with "human-machine coexistence" active disinfection technology (e.g., Kangbeijing’s DBD plasma technology) release plasma clusters nonstop even when people are in the room. They actively capture and destroy airborne viruses and bacteria, effectively reducing aerosol transmission risks in enclosed spaces. It’s like having a 24/7 invisible air guardian for your home, offering an extra layer of protection for your family’s respiratory health in the flu-prone winter.
