How long can I wear a mask in summer?

Once the mask is soaked with sweat, it should be replaced immediately

Otherwise, COVID-19 -19 can not be effectively prevented.

It is recommended to replace the mask every 1 to 2 hours in summer

It is not only wet, but also should be replaced in time when the mask is found to be damaged, dirty, smelly, unable to fit closely with the face or in and out of high-risk places. Even without the above, the mask cannot be used indefinitely.

Although wearing a mask will be muggy, wearing a mask correctly is not only a necessary measure to protect yourself, but also a civilized expression of respect for others. For the health of yourself and others, please continue to wear masks and change them frequently.
