The human being is more adapted to heat, by which hormones that control the thirst and the volume of water in the body will secrete less in winter. The aim of hydrate or rehydrate focuses on the own need to restore water imbalances that occur in the body as a result of the intervention of different factors and situations. One of the most characteristic and important is thermoregulation or maintenance of body heat balance. And it is precisely here where lies the main difference between hydrate in summer and winter. In summer we are subjected to higher temperatures throughout the day and especially in some geographical areas, which implies that even at rest our body temperature increase considerably and various mechanisms in our body aimed to lower them to initial levels being the most prominent to be raised sweating (skin vasodilation, increased breathing). This mechanism allows us to cool down with a good efficiency, but with water cost for our body, and specifically for our blood, which loses large amounts of plasma becoming denser.

Obviously, if we add to this circumstance the realization of physical activity we increase both the losses and the need to moisturize well. Therefore, it is in summer when we can most often find needs a good hydration or rehydration and with greater urgency in situations and sectors of the population of special weakness. In winter, though with one lower initial risk that in summer, we can also find a set of situations that trigger a water imbalance harmful to health and performance of people, and especially of any athlete. That is why we should be considered equally important to follow proper guidelines of hydration in winter and especially when sports are made in environments cold on height and intensity, adds Dr. David Jimenez Pavon. Proper hydration is convenient to drink water before exercise to prevent dehydration and changes in the balance of electrolytes.
