One of the earliest signs of puberty in many children is the development of new or stronger body odor. Parents may notice this after physical activity, such as sports, or simply through changes in clothing and laundry habits.
This is a normal part of development as hormone changes begin to affect the body. While it can be a noticeable transition, it is expected and simply reflects your child growing and moving into a new stage of development.
When is it normal for body odor to start?
It’s very common for children to begin developing body odor as an early sign of puberty. This can start as early as 8 or 9 years of age and is a normal part of physical development. These changes are related to normal hormone shifts in the body and simply indicate that a child is entering a new stage of growth.
What causes it?
As children enter puberty, changes in sweat glands can lead to increased body odor. The apocrine glands become more active and release sweat that contains oils. When this interacts with normal bacteria on the skin, it can create a stronger odor.
Areas of the body where hair is growing may also trap sweat and bacteria more easily, which can contribute to odor changes during this stage of development.
If you notice increased body odor in your pre-teen or teen, it can be a good opportunity to talk with them about healthy hygiene habits and ways to care for their changing bodies.
7 Body Odor Prevention Tips:
- Don’t forget the soap. Regular bathing with soap and water helps remove sweat, oil, and bacteria that can contribute to body odor. Most standard body washes are effective for daily use, and there is typically no need for special antibacterial soaps. Be sure to focus on areas where sweat and odor tend to build up, such as the underarms, feet, and groin. The scalp can also produce sweat and oil, so regular shampooing is important as well.
- Shower regularly. Once body odor begins to develop, it’s generally helpful for children and teens to shower daily or every other day. Those who are especially active or participate in sports may benefit from more frequent bathing. If your child has sensitive skin conditions such as eczema or other dermatologic concerns, it’s a good idea to check with their pediatrician for individualized recommendations on bathing routines and appropriate skin care products.
- Use deodorant, with or without antiperspirant. Deodorants help reduce or mask body odor, while antiperspirants are designed to decrease sweating. Many products combine both, often using ingredients such as aluminum-based compounds to help reduce sweat from the glands. Deodorant ingredients, such as fragrances and other odor-neutralizing components, help minimize or cover body odor. Together, these products can be helpful tools as children and teens navigate the normal changes that come with puberty.
- Consider fragrance- or aluminum-free options for sensitive skin. Some children and teens may experience skin irritation from fragrances or certain antiperspirant ingredients. If this occurs, switching to a gentler product can be helpful. Look for labels such as “fragrance-free,” “hypoallergenic,” or “for sensitive skin.” There are also many aluminum-free deodorant options available that may be better tolerated for those with sensitive skin.
- Wear socks with shoes. Wearing clean socks with shoes helps reduce moisture buildup and can minimize foot odor. Cotton socks or moisture-wicking materials are especially helpful, particularly for active children and teens. Changing socks regularly—especially after sports or long periods of activity—can also make a noticeable difference in keeping feet dry and reducing odor.
- Choose breathable fabrics when sweating. Clothing made from breathable materials such as cotton, linen, or wool can help keep the body cooler and reduce moisture buildup during the day. It’s also helpful for children and teens to change out of sweaty clothes after exercise or sports. This can help reduce odor and keep skin more comfortable as the body goes through normal puberty-related changes.
When to see your pediatrician:
Remember that body odor is a normal part of growing up, and the strategies above can help children and teens manage it effectively. However, if these approaches don’t seem to be working, it may be helpful to explore whether there are other factors contributing to the issue.
Talk to your doctor:
- if your child is experiencing frequent or excessive sweating
- if sweating or body odor is beginning to affect their confidence, mental health, or social interactions.
In some cases, the pediatrician may recommend evaluation or testing to rule out underlying medical conditions that can contribute to increased sweating or body odor. They can also discuss treatment options if needed, including conditions such as hyperhidrosis, which involves episodes of excessive sweating.
You should also check in with your child’s pediatrician if you notice signs of puberty, including body odor, beginning earlier than age 8.
