At the peak of the summer season, there are two things that save us from the high temperatures: the air conditioner for indoor environments and the water consumption when we are out. And we all agree at one point: we want the cold water as cold as possible, preferably with ice! But, if we are now rescued from the hot situation, the heat and sweat, we seem to have known something wrong so far. Cold water is not the best solution for the days of hot scorching heat. And the reasons, are as follows. Are you ready to learn with us? Here we go ...
1. When we drink cold water, we slow down the circulation of blood throughout the digestive tract, as it is known that in the cold environment, the blood veins are narrowed, thus doing what is known as vasocontraction.
2. The drinks we eat, while we drink cold water, do not serve us as a source of energy. Rather, the energy we provide from them does not go to cope with our daily activity, but to regulate our internal temperature.
3. Cold water reduces the amount of mucus secreted along the digestive tract, which makes it possible to weaken the immune system and make it easier to touch bacterial or viral infections in the gastrointestinal tract.
4. Drinking drinks, while drinking cold water, are metabolized more slowly to the body. This metabolic slowdown can easily lead you to your weight gain. 
5. Lightweight body temperature. The purpose of why we consume cold water in the summer is best achieved, but the collapse of our body temperature leads us very easily to the expense of internal energies that we can use for our daily activities
