Keep exercising every day to enhance your immunity. Old people's physical function is in a state of decline and weakness, and their physical immunity is obviously not as good as that of young people, so they can exercise indoors. Reasonable diet, regular work and rest, and good mental state. If the elderly suffer from long-term chronic diseases, they should not only take medicine on time, but also listen to some doctors' suggestions and do something to strengthen their personal health.

If the elderly need to go out, they must wear masks. Masks should be bought in regular pharmacies, preferably medical surgical masks. After returning home, the mask should be thrown into the trash can for scrap. But if it is not necessary, the elderly should try not to choose to go out, so as not to increase some hidden risks.

As the family members of the elderly, in addition to paying attention to the health of the elderly, we should also do some protection when going out, because we are in the same space with the elderly after returning home. Individuals should try not to go to high-risk or medium-risk areas. If necessary, they can choose to have a nucleic acid test once a week or half a month. Old people often need more ventilation in the windows when they are at home. They should open the windows for at least two hours every day, and often clean their rooms to prevent dust or other bacteria and viruses from falling down.

If the elderly feel unwell during epidemic prevention, they must actively communicate with the property management personnel in the community and get in touch with the doctors in the hospital as soon as possible. We should not delay the illness of the elderly because of the epidemic prevention policy. There have been cases in the past, because the epidemic policy did not allow the elderly to leave the community, which led to the aggravation of their illness and eventually death. In view of this, relevant administrative departments should also introduce some flexible and safe protective measures.
