The main cause of oral ulcer after exercise is lack of water. Exercise itself will not cause excessive internal heat. The fire was caused by not replenishing water in time. During exercise, you must consume a lot of water, including sweat and urine. Be sure to drink some salt water after exercise to avoid getting angry.

Sweating will take away a lot of salt in the body, so it is necessary to replenish salt. If you lack salt, it will cause cramps, muscle aches and other symptoms. Hang in there. Physical health is the capital of work, which can be divided into two types: insufficient and surplus. Deficiency fire is characterized by low fever, night sweats, upset and dry mouth. Excess fire is characterized by repeated oral ulcers, dry mouth, short and red urine, and irritability.
