Why it is not good to shower with cold water in heat wave

When the heat squeeze, many people turn to a ice water shower As a quick solution to cool off. However, that feeling of relief can be a mirage. The pharmacist and disseminator Álvaro Fernández has warned in networks that showering with very cold water is not the best idea, and that can even end up causing the opposite effect to which it is sought.

“At first, you cooled your body with the water and you have 10 minutes of taste, but later, Safocón. You will be even worse,” he explains. According to him, when exposing the body at such a low temperature, it reacts by activating its defense mechanisms, including the Heat production To compensate for cooling.

Why the body reacts generating more heat

Although we do not perceive it with the naked eye, when we show us with very cold water Skin blood vessels contract. This phenomenon, known as vasoconstriction, reduces heat loss through the surface of the body. As a result, the body retains heat instead of releasing it.

In addition, when deceiving the body making him believe that the outer temperature is very low, two natural refrigeration mechanisms are blocked: sweating and blood flow to the skin. That is, although when leaving the shower we feel immediate relief, soon the body is more easily reheated and the feeling of embarrassment can be even greater.

What is the best way to shower with extreme heat?

The most effective solution, according to experts consulted by the magazine Know how to liveis to opt for a Tempered or warm shower. This temperature helps to regulate body heat without causing a thermal shock that deactivates natural cooling mechanisms.

Another practical recommendation is to progressively reduce the temperature of the water towards the end of the shower, leaving a few seconds of transition between each change, so that the body is acclimated without stress. And at the end, avoid rubbing vigorously with the towel, since friction can also increase body temperature.

In short, showering with very cold water can be tempting when it’s hot, but it is not always the best option. Although the initial freshness is pleasant, the rebound effect can play against. A temperate shower, on the other hand, helps the body to cool off more sustained and efficiently.
