Caution for joggers
fotosearch.com
Joggers, and especially marathon runners, in a hot, humid-climate such as is found in many areas of the Far East, face additional risks. Circulation of blood to internal organs, having been diverted to the muscles, becomes very deficient. Because of lack of blood flow to the kidneys, the blood pressure can go dangerously high. Deficient blood flow to the liver results in insufficient nutrition to the liver cells. The blood may clot too easily, thus occasionally contributing to a heart attack, and even death.
A more frequent complication, especially in hot, humid countries, is hyperthermia (over-heating). The body becomes so hot that even brain damage may result.
