Sweat in the process of discharge not only takes away the heat brought by the high temperature of the environment, but also takes away the excess heat generated by the human body’s own movement. At the same time, it contains a large amount of metabolic waste, which is also discharged from the body with its own loss. Sweat contains a substance called “lactic acid”, which combines with fatty acids secreted by sebaceous glands to form a natural bactericide, prevent bacterial invasion and protect the skin. Frequent use of antiperspirants will inhibit the normal perspiration of the human body, make the heat in the body unable to be discharged, lead to increased body temperature, dizziness, chest tightness and other discomfort, which is harmful but not beneficial to the human body.
At present, the common antiperspirant products on the market mainly block the sweat gland ducts that produce sweat, so that the secretory cells therein shrink, thereby achieving the goal of reducing sweat secretion. Some antiperspirants are irritating to the skin, especially when artificial fragrances and other ingredients are added, which may cause skin allergy. People with allergies should be more cautious. Before use, it should be tried in a small area on the inner side of the upper arm. If there is no erythema, pruritus and other symptoms, it can be safely used. Avoid antiperspirants when skin is damaged. This is because the chemical components in antiperspirants can enter the blood circulation through wounds, which not only irritates skin wounds, but also causes other adverse reactions. Antiperspirants are suitable for areas prone to perspiration or with heavy body odor, such as armpits, necks, soles of feet, armpits, etc. generally, they are not applied on the face, let alone on a large area of the whole body. Otherwise, sweat cannot be discharged, which will cause difficulty in radiating heat and body temperature disorder. In severe cases, it can lead to heat shock. If you sweat due to heavy exercise, you should clean your skin first, or wipe off the sweat with paper towels, and then use antiperspirant. Use antiperspirant products with caution in summer. It’s best to let sweat come out naturally, take away excess heat from the body, and reduce body temperature.
