In the heat of summer, you may be confused by excessive sweating or suffer from a pungent odor! Part of the population belongs to the sweaty body, the slightest movement on the sweating, sweating too much on the one hand, leading to the loss of fluid electrolytes caused by fatigue, on the other hand, will also cause armpit odor and other skin disorders. Sweat glands secretion of smelly substances or cause bacterial growth and lead to armpit odor and other skin diseases, is a beautiful face of the crowd’s hidden, so the deodorant antiperspirant products have become a lot of women’s portable must-have things, but in the use of such products to achieve deodorant antiperspirant at the same time, behind the scenes, also hides a number of unfavorable factors also need to be vigilant. Medical research shows that the skin sweat glands are divided into small sweat glands and top secretion sweat glands, the whole body skin sweat glands have 2 to 5 million, per square centimeter has 143 to 339. Environmental temperature exceeds 31 ℃ will be dominant sweating, sweating is the body’s main way of heat dissipation, play an important role in regulating body temperature, in addition to sweat through the role of keratin softening, to keep the skin soft, smooth, moist, and the formation of a lipid film to protect the skin from damage, but also to make the body urea, lactic acid and other metabolic wastes from the body to participate in the metabolic process. Commonly used antiperspirant is through the product contains compounds that make the sweat gland duct blockage, secretion cell atrophy, so as to achieve the purpose of reducing sweat secretion. If too much frequent large-scale use of antiperspirant, artificial inhibition of sweating, it will be because of the blockage of sweat gland ducts, metabolic waste can not be normally discharged, the lack of lipid film on the skin’s protective effect, the excreta of the skin continued to stimulate the emergence of sweating, rash, itching and other symptoms, or triggered by hair follicle infections. If the use of antiperspirant containing formaldehyde, tannic acid, flavors, additives and other antiperspirants, may lead to sensitized people induced different degrees of allergic diseases, such as allergic rhinitis, contact dermatitis and so on. If used for a long period of time, due to the accumulation of compounds in the skin or systematic absorption, may cause poisoning phenomenon occurs, or even carcinogenic risk. In very high temperatures or sports, if a large area of the body coated with antiperspirant products to force stop sweating, will inevitably lead to high body temperature, more prone to heatstroke, and in serious cases, may appear heat shock. Therefore, in the use of antiperspirant products must be careful, we recommend: 1, in the choice of antiperspirant must choose the regular manufacturers, with a qualified batch number, and identify the full composition of the product. 2, in the formal use of the former, should first be in the inner upper arm or the skin behind the ear in a small area of low-intensity trial, such as red skin rash or itching and burning phenomenon, that is, should not be used. 3, should not be used on a large area or the whole body, so as to avoid too much antiperspirant and systematic absorption triggered by poisoning or allergic reactions. 4, we can use antiperspirant instead of other antiperspirant methods, such as diligent bathing, hygiene, keep the environment cool, wear sweat-absorbing and breathable clothing, eat less spicy and stimulating food, maintain a relaxed mood and emotional stability.
