Sweating: What You Need to Know
Sweat is produced by sweat glands. There are two types: eccrine sweat glands and apocrine sweat glands. Essential for the proper functioning of the body, perspiration plays several roles:
It has a thermoregulation function, meaning it helps regulate body temperature. The production of sweat allows the expulsion of excess heat in cases of intense exertion.
It has a detoxifying function: perspiration allows for the elimination of toxins and organic waste.
It has a hydrating function: sweat contributes to the composition of the hydrolipidic film that protects and hydrates the skin. The hydrolipidic film forms a protective layer on the skin's surface to shield it from external aggressors (sun, pollution, etc.) and to prevent dehydration.
Sweat is odorless; it is the bacteria present on the skin's surface that are responsible for bad smells. Indeed, these bacteria feed on sweat and produce the unpleasant odor we are familiar with.
How does deodorant work?
Unlike antiperspirant, deodorant does not block perspiration. It contains several compounds that act at different levels.
Whether it's essential oils like palmarosa or less natural compounds such as triethyl citrate, these ingredients are crucial in deodorants because they act directly on the cause of bad odors: bacteria.
Thanks to their microporous structures, certain clays such as diatomaceous earth powder or white clay are drying agents that can absorb their weight in moisture. Their antibacterial action also acts on the bacteria present on the skin, thus limiting the appearance of bad odors. Among the absorbent powders, it is also possible to mention baking soda, common in natural deodorants as an alternative to aluminum salts.
Fragrance agents, incorporated into formulas to mask odors.
The use of deodorants is recommended for low to moderate sweat flow. Deodorants today come in several forms: roll-on, solid stick, spray, and cream.
What practices should be adopted to limit unpleasant odors?
The use of a deodorant is necessary to limit the emergence of unpleasant odors. However, it will remain ineffective without proper hygiene. There are a few practices to adopt in order to combat bad odors:
Take a shower daily to eliminate bacteria on the skin surface;
If you are truly bothered by odors, underarm hair removal may be a good option. Indeed, the presence of hair can intensify unpleasant smells. ;
Wear loose and light-colored clothing;
Avoid synthetic fabrics and favor natural materials such as cotton, linen, wool, and silk ;
Limit the consumption of certain foods: spices, coffee, alcohol, processed meats;
Drink plenty of water;
Thoroughly dry your skin after showering, as moisture promotes the proliferation of bacteria;
Learn to manage your emotions, as stress promotes perspiration.
What is the difference between a deodorant and an antiperspirant?
Both deodorant and antiperspirant are used to combat unpleasant odors. However, they differ in how they function.
Indeed, deodorant prevents bad odors by eliminating bacteria on the skin's surface. It also masks odors thanks to fragrances. It can absorb moisture due to the presence of certain porous powders like diatomaceous earth or white clay.
On the other hand, the antiperspirant combats sweat odors by blocking perspiration. It reduces sweating through ingredients such as aluminum salts. These tighten the pores and thus reduce perspiration. The antiperspirant also destroys bacteria found on the skin's surface.
