Because the more they run, the more they produce saliva. And, in order not to have excess in the mouth, they end up spitting. High saliva production occurs when we practice intense physical exercises, which require more forced breathing. As the nostrils do not have enough space for the entry and exit of air that the body demands, we breathe more through the mouth, which becomes dry. When this happens, it’s common to drink liters of water to quench your thirst. In the case of players, it is difficult to drink water all the time and, to avoid dehydration, the central nervous system stimulates the salivary glands, which produce more saliva to moisten the oral region. “From the point of view of thermoregulation and hydration, the right thing to do would be to swallow saliva”, explains Raul Santos de Oliveira, sports physiologist at Unifesp. According to him, spitting is nothing more than a habit of the players, and this attitude only increases the dehydration of the body.
– The body produces, on average, one liter of saliva per day. During physical activity, this production increases
– Factors such as air humidity, pollution and training conditions also influence the volume of saliva produced
