On a hot summer day, there's nothing more than a good glass of ice water to help fight heat and humidity. But beware! If you are used to drinking water at this temperature you should be aware of some of its consequences, because, like iced tea, frozen or very cold water hides a lot of dangers for your health.
Loss of energy: Cold water produces a significant loss of energy in the body, which manifests itself in a generalized exhaustion. Many people drink cold water in order to wake up and reactivate, but what they do not know is that this stimulating effect is momentary and not very helpful.
It irritates the throat: when you drink very cold water you also run a great risk to health. When such cold water is ingested, it destroys a large quantity of the mucus produced and accumulated in the nasal passages to protect the lungs and also causes an unpleasant sore throat.
Slow down the heart rate: It is true that before a sudden change in temperature, the body will strive to work fast and balance the overall temperature as soon as possible, but it is inevitable that these low temperatures affect the circulation system, including the vagus nerve , responsible for controlling, among other things, the heart rate.
Hinders hydration: As we mentioned above, the body tends to heat the cold liquid that comes before being put to work in the bloodstream and digestive tract, so drinking cold water simply slows down the body's rehydration process .
Blocks intestinal transit: For some people, it can produce terrible diarrhea, because in the effort to maintain body temperature, the body is too exhausted to digest efficiently and simply chooses to expel most of the water and nutrients. food that you have eaten.
For others, the opposite occurs. The cold causes the food to solidify and harden, so the waste remains accumulated in the intestine and can not be expelled.
