Sweat and odour for men

What it is

Men tend to sweat more than women, and more sweat in the underarms, groin and feet means more odour from bacteria.

How it works

Men often have more active sweat glands and more body hair, which traps moisture and bacteria.

Why it matters on darker skin

Heat, humidity, long hours in suits or uniforms, and exercise all increase sweating.

Causes and triggers

Exercise, heat, synthetic fabrics, stress.

What helps — and why it works

Shower daily and after exercise, using soap on underarms, groin and feet. Apply antiperspirant at night to dry skin and again in the morning if needed. Choose breathable fabrics, change socks daily and rotate shoes. Keep underarm hair trimmed. Daily wash and fresh clothes: cuts bacterial load. Expected timeline: immediate. Night-time antiperspirant: more effective than morning. Expected timeline: days. Trim underarm hair: less trapped sweat. Expected timeline: immediate.

More detail

Men tend to sweat more than women during exercise and in heat, and coarser body hair holds sweat against the skin for longer, giving bacteria more time to produce odour. Practical steps make a big difference: shower after exercise or work in the heat, wash the armpits, groin and feet with a gentle cleanser, and dry thoroughly. Trimming underarm hair reduces the surface where sweat and bacteria collect. Wear moisture-wicking or cotton fabrics, change socks daily and rotate shoes. Antiperspirants containing aluminium salts work best when applied at night to dry skin, because sweat glands are least active during sleep and the active ingredient has time to form plugs in the ducts. If sweating soaks clothes or interferes with work, consider clinical-strength aluminium chloride products or see a doctor. New night sweats, weight loss or fever with sweating need medical assessment.

What to avoid and why

Avoid covering odour with strong fragrance only, and wearing the same shirt two days running.

Common mistakes

• Layering fragrance over odour.
• Ignoring sudden changes in smell or sweat.

Body care basics in a hot climate

Heat and humidity mean the body sweats more, which feeds the bacteria and yeasts that cause odour, rashes and some types of body acne. A daily lukewarm shower with a gentle, soap-free or mild cleanser, thorough drying of skin folds and between toes, and fresh, breathable cotton clothing prevent many problems. Moisturise straight after bathing while skin is still damp so water is sealed in; this matters even in humid months because frequent washing strips natural oils, and it matters most during harmattan. Avoid sharing towels, razors and sponges, which spread fungal and bacterial infections. When shaving, use a sharp blade, shave with the grain and do not stretch the skin; for curly hair a guarded trimmer is often better. Be cautious with body-lightening, 'carrot' or 'toning' lotions: many contain undeclared steroids or mercury. If a rash spreads, keeps coming back, or appears with fever, see a doctor rather than trying more creams.

Choosing body products

For most people an unscented, gentle cleanser and a plain moisturiser are enough. Antiperspirants containing aluminium salts are the most effective way to reduce sweating and are best applied at night to dry skin. Fragranced body sprays and deodorants are a common cause of allergy; fragrance-free options are kinder to sensitive skin. Aerosol products are easy to over-apply and some have been recalled for benzene contamination, so roll-ons and creams are a sensible default. For fungal rashes, plain antifungal creams such as clotrimazole are better than combination creams containing strong steroids, which can make infections spread. Always check for a NAFDAC number and a full ingredient list.

Questions to ask your doctor or pharmacist

Useful questions include: What do you think is causing this? Is it likely to come back, and how can I prevent it? Which products should I stop? How long before I should expect improvement, and when should I come back if it isn't better? Are there side effects to watch for? Is this treatment safe if I am pregnant, breastfeeding or for my child? Writing your questions down, bringing your products (or photos of their labels) and taking dated photos of the problem make an appointment much more useful.
