Body Odour in Men: Causes and Care

Underarm, foot, groin, and scalp hair can hold moisture and bacteria close to the skin. Exercise, heat, stress, and a physically demanding job may increase sweating. Tight or synthetic clothing can trap moisture, while shoes may retain smell between washes. Shaving is not required for hygiene, but trimming hair may make cleansing and drying easier for some people.

A new strong smell is not proof of a serious condition. However, odour with scaling, itching, pain, drainage, fever, or a major change in sweating should prompt an assessment.

Wash sweaty areas, dry them thoroughly, and change underwear, socks, and sportswear after sweating. Clean or air footwear and avoid putting damp clothes back on. Deodorant can mask odour; antiperspirant reduces sweat and should be applied to dry skin as directed. If shop products are inadequate, ask about [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/). [Botox For Sweating](/treatments/injectables/botulinum-toxin-for-hyperhidrosis/) may be discussed for persistent underarm sweating.

See a clinician if the smell continues despite good skin and clothing care, interferes with work or relationships, or comes with a rash or recurrent dampness. Seek prompt care for fever, pus, painful swelling, skin breakdown, or a sudden widespread change in odour or sweating.

Could this be excessive sweating or a skin condition? Which product is appropriate for my underarms or feet? Could any medicine, supplement, or recent health change be contributing?
