90% of people get it wrong! Doctor reveals the correct way to eliminate body odor

A common misconception about combating body odor is how antiperspirants are applied, with experts noting that about 90% of people get it wrong. Dr. Huang Xuan, a thoracic and critical care physician, explained that antiperspirants containing aluminum salts need time to absorb moisture and block sweat ducts. Therefore, the most effective time to apply them is the night before, when the skin is completely dry and sweat glands are less active.

Antiperspirant must be used 'the night before, when the skin is completely dry.'

Sweat itself is largely odorless. The unpleasant smell arises from bacteria on the skin's surface breaking down proteins and fatty acids in sweat, producing volatile compounds. This process is exacerbated in the warm, humid conditions of summer. Dr. Huang emphasized that the core of odor control involves both inhibiting sweat and reducing bacteria.

Pure sweat is actually odorless. The embarrassing sour smell is the 'metabolic product' (bacterial excrement) after bacteria on the skin surface break down the protein and fatty acids secreted by the apocrine glands.

For immediate relief after sweating, it is advised to first dry off with a wet wipe or towel to cool the skin. Only then should one apply a deodorant or antiperspirant, preferably one with antibacterial properties, rather than attempting to mask the odor with strong perfumes. Mixing strong perfume with body odor can create a more offensive smell, especially in enclosed spaces.

When you feel sweaty and have an odor, do not try to cover it up with perfume or deodorant. High-end perfume mixed with body odor will only evolve into a more destructive biochemical weapon in a sealed air-conditioned car.

Clothing also plays a role, as synthetic fabrics like polyester can trap oils and bacteria, leading to persistent odors even after washing. The article suggests adding baking soda or a sterilizing agent to laundry and opting for breathable materials like cotton or linen for daily wear. For intense exercise, performance fabrics remain beneficial. If persistent sweating or odor issues remain despite these measures, consulting a doctor for medical treatments is recommended.

Sometimes it's really not you who smells, it's your clothes!
