Why Do I Smell Different Now?
By the eva team · · 2 min read
A stronger body smell is a common puberty change. Puberty activates sweat glands more fully, including apocrine glands around areas such as the underarms and groin. Sweat itself is not usually the main source of odour—the smell develops when sweat and skin oils interact with bacteria naturally living on the skin. Regular washing, clean clothing and a suitable deodorant or antiperspirant can help you stay comfortable.
1. Why Do I Smell Different Now?
You might notice that your underarms, feet or clothes smell stronger than they used to, especially after school, exercise or a hot day. This does not mean you have suddenly become dirty. Increased sweating and body odour are normal changes that often begin during puberty.
2. Puberty Makes Your Sweat Glands More Active
You are born with millions of sweat glands, but they become more active during puberty. Hormone changes can make you sweat more, particularly during exercise, hot weather or emotional situations such as nervousness and stress. Sweating is also how your body helps regulate its temperature.
3. Sweat Is Not The Whole Smell
Fresh sweat is not usually what creates strong body odour. During puberty, apocrine glands release sweat and oils in areas such as the underarms. Bacteria that normally live on the skin break these substances down, producing the scent you notice. Hair can also hold moisture and odour in these areas.
4. Simple Hygiene Usually Helps
Wash areas that collect sweat, such as the underarms, feet and groin, using water and a gentle cleanser. Dry your skin well, change underwear and socks regularly and change out of damp sports clothes. Breathable fabrics can also help your skin stay cooler and drier.
5. You Can Use A Product For Extra Help
A deodorant helps reduce or cover body odour, while an antiperspirant reduces the amount of sweat reaching the skin. Some products combine both. Sensitive skin may do better with a fragrance-free or hypoallergenic option, especially if a product causes stinging, redness or a rash.
6. A New Smell Is Normal But You Can Ask For Help
Body odour is usually a manageable part of growing up. Talk to a trusted adult or healthcare professional if the smell changes suddenly, does not improve despite regular care, or if sweating becomes constant, excessive or begins affecting your confidence and daily life. Puberty-related body odour before age 8 should also be discussed with a clinician.
