After catching a cold, it is appropriate to engage in some mild exercise, such as walking or slow-paced walking. It is crucial not to partake in intense physical activities as they can lead to fatigue and a decrease in immunity, potentially worsening bacterial infections. Moreover, intense exercise can cause the sweat pores to expand, further aggravating cold symptoms. After a cold, the body tends to be weaker, so it is advisable to drink more ginger sugar water, rest adequately, and avoid spicy, greasy, and irritating foods. Drinking plenty of water is also important. If there are symptoms of fever, physical methods should be used to reduce the fever.
