Will wearing a mask worsen a cold?
Generally, wearing a mask when you have a cold does not worsen the condition; on the contrary, it helps reduce virus transmission and protects the respiratory tract. However, attention should be paid to the choice of mask and proper wearing methods. Here's a detailed explanation:

Colds are mostly caused by viral infections. When patients cough or sneeze, they release virus-containing droplets. Wearing a mask prevents these droplets from spreading and infecting others. Meanwhile, after catching a cold, the respiratory mucosa becomes more sensitive. A mask can block external dust, cold air, and other pathogens, reducing irritation to the respiratory tract and alleviating symptoms such as coughing and sore throat. It is recommended to choose breathable surgical medical masks and avoid using overly thick or tightly sealed masks.
If a mask has poor breathability or is worn too tightly, it may cause breathing difficulties, stuffiness, and sweating. This discomfort is especially noticeable when nasal congestion accompanies the cold. In addition, masks should be replaced regularly. A mask worn for too long will accumulate moisture and bacteria, potentially increasing the risk of respiratory infection. It is generally recommended to replace the mask every four hours, or immediately if it becomes damp or contaminated.
Wearing a mask during a cold is an essential protective measure—the key lies in selecting the right mask and wearing it correctly. At the same time, drink plenty of warm water, ensure adequate rest, and support your body’s recovery, thereby protecting both yourself and others’ health.
