Proper hydration is essential at all times, but especially when carrying out physical activity, since sweating causes the human body to lose more water. It is important to note that Dehydration increases the feeling of heaviness and fatigue and makes it difficult to practice sports.
But more than to improve physical performance, hydration should be kept in mind for health reasons. By burning calories, the body increases body temperature and to regulate it appears sweating, through which not only water but also minerals are lost. If these liquids and minerals are not replaced, the lack of hydration it will have negative consequences: increased heart rate, hyperthermia, cramps, headache.
Our body needs maintain a stable temperature so that all our physiological processes develop normally. The realization of some sport activity makes our body temperature rise and our sweat glands begin to produce sweat so that, with its evaporation, our body will cool and lower body temperature.
This process natural it allows us to balance our temperature.We must bear in mind that with perspiration we lose very important mineral salts for our body.
The composition of sweat in normal conditions it is quite stable although It may vary depending on our diet and health status. It is basically composed of water where salts containing sodium, chlorides and small amounts of potassium, magnesium, zinc, iron, calcium, some nitrogenous organic compounds and vitamins are dissolved.
Maintaining a balanced diet and a sufficient supply of water our body is prepared for this loss of salts.
