In summer, because of the heat and intense sweating, you are especially thirsty. However, not all drinks are equally suitable for quenching thirst. It is important to choose that drink that refreshes best. Drink a sufficient amount of liquid - in the heat it's just necessary. If this is not done, then there is a risk of disturbance of the water-salt balance in the body. In addition, drinking helps to cool down and avoid a possible heat stroke, from which there is no protection even in the shade.
