Running is a good activity for health, but overtraining can have the opposite effect. When the amount of exercise exceeds the safe threshold, even people with good physical condition may face increased cardiovascular and cerebral blood vessel risk.
In addition, excessive exertion also causes the body to accumulate many fatigue-causing substances in blood vessels. If overloaded for a long time, blood vessel walls can be damaged and gradually accumulate plaques. These minor lesions accumulate over the years and when facing factors such as high blood pressure, strong emotions or sudden temperature changes, they can form blood clots, leading to heart attacks or strokes. The danger is that this process often has no obvious signs.
Therefore, some high-risk groups need to be especially careful when exercising. People with a history of heart disease, high blood pressure, families with cardiovascular disease, or over 65 years old should closely monitor their health and exercise at an appropriate level. If symptoms such as palpitations, chest tightness or abnormal fatigue appear, stop exercising immediately and go to a medical facility for cardiovascular check-up.
