In the short term, masks are indeed very important as a “shield” against the new pneumonia epidemic. But the epidemic will eventually pass, and in the long run, personal resistance is more important than masks. Therefore, maintaining a healthy lifestyle and good personal habits is the “hardcore” approach. Exercising, maintaining a good state of mind and ensuring hand hygiene are important measures to avoid the spread of germs and prevent medical infections, and moving prevention forward is the only way to beat the disease.
