What will happen if you wear new unwashed underwear?

Wearing new, unwashed underwear may cause skin irritation or allergic reactions and may increase the risk of infection. New underwear may have residual chemical agents, dust or microorganisms during production and transportation. Direct contact with the skin may lead to contact dermatitis, perineal itching and other problems. People with sensitive constitutions are at higher risk.

New underwear often contains chemical residues such as formaldehyde, which is used to prevent wrinkles and hold the shape. These substances may irritate the skin, causing redness, itching, or burning. Some dyes may also cause allergic reactions, manifesting as local rashes or eczema-like changes. New underwear made of chemical fiber can easily generate static electricity when rubbed, which may aggravate skin discomfort.

Warehousing and transportation may cause underwear to be contaminated with dust, mites or pathogenic bacteria. Women wearing new unwashed underwear may disrupt the balance of perineal flora and increase the risk of fungal vaginitis or urinary tract infection. Men may develop jock itch or scrotal eczema due to friction in the crotch area. Children's skin barrier function is weak and they are more prone to allergies or infections.

It is recommended that all new underwear be washed and dried with neutral detergent before being worn for the first time. Pure cotton material is more conducive to breathability and moisture absorption. If you have persistent itching, rash or abnormal discharge, you should seek medical advice promptly and avoid scratching or self-medication. On a daily basis, you should choose underwear products that comply with national textile safety standards. People with allergies should pay extra attention to cleaning procedures.
