Having a cold once a month is considered to be a more frequent cold, mostly caused by the body’s lower immune system. Adults have an average of 2-4 colds per year, and preschoolers have an average of 4-8 colds per year. For older and frailer people who have frequent colds, a pneumococcal vaccine or flu vaccine can be given in the fall to ward off influenza, which can reduce symptoms. In daily life, we should pay attention to increase nutrition, strengthen physical fitness, appropriate outdoor exercise, pay attention to drink more water, eat more vegetables and supplement vitamins, which can improve the body’s ability to resist diseases.
