When you have a cold, you should never exercise too much, as it is very physically demanding. It is better to take more rest and replenish nutrients to promote recovery from the cold. Exercise is not conducive to recovery from a cold because the pores are open when you sweat a lot and it is easy to catch a cold. If you get cold during the cold, it is likely to aggravate the cold, and you should not exercise when you have a cold. You should rest more, drink more water, and eat more fresh fruits and vegetables rich in vitamin C. If the symptoms are serious, you should also use cold medicine for treatment to avoid aggravation of the cold. You can use aminophenol pseudo-lax dispersible tablets, aminophenol xanthamine granules or cold and fever granules for treatment.
