Why Does Body Odor Get Stronger During Puberty?

An age-appropriate guide to sweat, deodorant, showering, clothes and when sudden odor changes need attention.

Reviewed for clarity · Updated 13 Aug 2026

Why this answer makes sense

Separate the possibilities before you act.

Odor and sweating are related but not identical. Deodorant targets odor; antiperspirant reduces sweating. Clothing can also hold odor even after the skin is clean.

Real-life scenario

What this can look like in everyday life

You shower, put on clean clothes and still notice odor later. That does not automatically mean you are unclean — sweat, bacteria on skin, clothing fibers, heat, hormones and product buildup can all change the result.

Questions that change the answerIs the odor on skin, hair or clothing?Did sweating change suddenly?Is there a new product, medication, life-stage change or illness context?

Useful facts

Keep these points in mind

Whole-body deodorants can reduce odor but are not the same as treatments for excessive sweating.

Strong or deodorant soaps can irritate sensitive skin.

Sudden major changes in sweating, especially with other symptoms, should not be dismissed as hygiene.

01

The body is changing, not failing

Puberty changes sweat-gland activity, skin oil and body hair. Bacteria on the skin break down sweat and create odor, especially in warm areas such as underarms and feet.

02

Build a simple routine

Shower or wash sweaty areas regularly, dry well, wear clean underwear/socks and change a shirt after heavy exercise. Deodorant targets odor; antiperspirant reduces sweat.

03

Clothes can hold smell

Sports uniforms, bras, polyester tops and socks can retain odor even after the body is clean. Wash sweaty garments and let shoes dry between wears.

04

Ask for help if the change is extreme

If sweating or odor is suddenly very different, drenching, accompanied by illness or causing major distress despite a reasonable routine, talk to a parent/caregiver and clinician.

Growing Up & PubertyFirst Period: What to Expect and What You Actually Need

A first period may be light or heavier, red or brown, and irregular at first. You need a menstrual product that feels manageable, clean underwear, a simple hygiene routine and someone you can ask for help. You do not need special intimate cleansers.

Read answer Personal Care & HygieneHow Often Should You Wash a Bra?

Wash a bra when it is sweaty, visibly soiled, smells, has absorbed body products or feels uncomfortable. Everyday bras may tolerate more than one wear if they are dry and clean; sports bras usually need washing after sweaty workouts. Follow the care label and rotate bras so they dry fully.

Read answer Sweat, Odor & MoistureWhy Do My Armpits Smell Soon After Showering?

Underarm odor can return quickly if you start sweating again, if odor is held in clothing, or if deodorant is not controlling the problem you actually have. Deodorant targets odor; antiperspirant reduces sweat. A sudden major change in body odor or sweating deserves medical discussion if it persists.
