The mistake of bathing right after going to the sun

“When you come back from being outside in the sun, the body sweats and radiates heat, the body is wet with sweat from the skin, seeping into clothes, creating a feeling of wet and viscous discomfort and frustration. If you take a bath right now, clogging pores. Sweat cannot escape, reducing body temperature, easily causing colds, “doctor Vu shared.

Accordingly, you should wait at least 20 minutes for the sweat to dry before bathing. The body has an automatic thermoregulation mechanism, the average body temperature is about 37 degrees Celsius, when temperature If it is too high, the sweat secretion is activated, the pores expand to secrete sweat, causing the body temperature to drop.

Similarly, after training sport Also, do not take a cold shower right away, the capillaries are dilating to radiate heat, the body encounters cold water, the external blood vessels automatically constrict, causing blood pressure to rise, leading to the risk of stroke.

What to do to be more comfortable after going to the sun?

During sports practice or when going outside in the hot sun and returning home, it is necessary to add water for the body continuously, drink in sips and divide the drinking time evenly, do not drink too much water at one time.

Sit at home to rest, drink a glass of cool water (filtered water, smoothie …) or eat fruit. Do not use a lot of ice because long-term effects on the pharynx mucosa, gastrointestinal tract, can cause heat shock. Take a cool towel to wipe your sweat, about 30 minutes then take a shower. Do not let fans or air conditioners blow directly on the body (avoid sudden temperature changes). When taking a shower, do not pour water from the top of the head, should wet the feet and hands first.

After going out in the sun, you should take a break to wipe your sweat, only shower after 30 minutes and don’t shower from the top down SHUTTERSTOCK

After bathing, do not go to the wind or enter the air-conditioned room with the temperature too low, which is also a way to avoid sudden temperature changes that the body cannot adapt.

In addition, the temperature should not be too low, changing the body’s state from high temperature to low temperature environment, causing dizziness for the body. When in the room air conditioning, the temperature is not high enough for the sweat to evaporate, so the sweat is easily absorbed back and causes a cold. Blood vessels can suddenly constrict, leading to increased blood pressure and increased risk of stroke.
