with high Temperaturesbegins another suffering with sweatingwhose effects are multiplied by exceeding the standard scores to the heat of the sunAnd knowing the following seven facts spotted by NPR, may help you enjoy the salt-rich sweat drops that help your body stay cool.

• How does sweating cool the body?

Millions of glands in human skin secrete sweat, which is mostly water and salt. These glands look like coiled rings that move some of the fluid flowing in the spaces between cells, bones, and organs, up and out through the skin.
As the sweat drops reach the skin, the process of evaporation begins, as the liquid sweat beads turn into a gas that evaporates in the air, taking with it some of the heat of the blood located directly under the skin. It monitors the temperature of the internal parts of the body so that it can perform its functions.

• Does sweat smell bad?

The sweat is mostly odorless, which is especially true for the sweat of the forehead and arms, but the sweat of the armpits and thighs looks different, as the sweat glands in those places are exocrine glands that release a rich type of protein on which bacteria feed, and as a by-product of these bacteria an odor is generated the body.

• Is it necessary to eliminate the bacteria that cause the smell of sweat?

Some may turn to antibacterial soaps to eliminate bad odor, but reports from NPR science workers advise that you wait, as microbes that emit body odor help protect the skin from dangerous pathogens and prevent eczema.
Scientists advise that a normal, gentle suds is enough to get rid of the bad odor, at least temporarily, without killing bacteria.

• Who sweats more, human or animal?

Humans sweat more than animals, and most animals don’t, but they do resort to other ways to guard once morest overheating — by panting, for example — if you can’t find shade, a river, or a pool, according to NPR’s Rebecca Hercher, in her exploration. For the ways in which different objects keep their cool.

• Which is better on hot nights, a warm or a cold bath?

The answer may not make sense, but researchers tell NPR that a warm or lukewarm evening bath an hour before bed draws heat from your body and cools you down before bed, as a result of water evaporating from your body, helping you sleep better and deeper.

• Does sweat attract insects?

Unfortunately, human sweat attracts mosquitoes and many other insects. Insects need sodium just as much as we do, which is abundant in our salty sweat.

• Do astronauts sweat?

Sweating can be a big problem for people in a low-gravity environment like space, where it’s hard to sweat even following a great deal of effort, so astronauts wear special underwear filled with cooling tubes while they spacewalk; The equipment that accompanies them with their ventilation system absorbs any excess moisture from the sweat in the air and recycles it into fresh water for the astronauts to drink.
