Many women believe that investing in workout-specific clothing will spare them from discomfort. However, as physical activity intensifies or goes on longer, the persistent friction between fabric and skin often leads to irritation.
When it comes to sports bras, chafing can be especially problematic, affecting not just comfort but also overall performance. Join us as we take a closer look at this common issue and explore solutions.
What Causes Sports Bra Chafing?
Constant Rubbing During Physical Activity
The constant rubbing of fabric against the skin frequently leads to irritation and, over time, painful abrasions. Specific areas, such as the underbust, around the straps, and along the band, are especially vulnerable due to the combined effects of pressure and repetitive motion concentrated in these zones.
When sweat softens the skin and blends with friction, the chances of chafing increase significantly. This combination not only intensifies irritation but also raises the risk of skin breakdown.
Synthetic Materials That Lack Breathability
Fabrics that fail to provide proper ventilation tend to trap heat and moisture against the skin. This problem is intensified by perspiration and body heat. Materials like untreated polyesters or nylons, when not designed for breathability, stick to the skin and prevent sweat from evaporating effectively. Athletes should pay attention to their choice of sports bras and select those made with moisture-wicking and breathable materials to reduce the risk of chafing.
Improper Fit (Either Too Tight or Too Loose)
While a bra that is too tight can press into the skin and cause discomfort, one that is too loose allows excessive movement, leading to friction against the skin. A well-fitted sports bra should provide support without being restrictive, reducing motion and preventing irritation.
Accumulation of Sweat That Increases Friction
When sweat accumulates, it saturates both the skin and the fabric, creating a damp environment that increases friction. This often occurs during high-impact or endurance activities, where continuous movement intensifies rubbing between the bra and sensitive areas like the underbust, shoulders, and back.
Unlike dry skin, which has a natural resistance to friction, damp skin becomes fragile and prone to irritation. As sweat dries, its salt content crystallizes, introducing an abrasive element that exacerbates the problem. Over time, this can result in severe chafing or even open sores.

How To Prevent Sports Bra Chafing
Select the Right Sports Bra Size
Sports bras follow the same sizing system as regular bras, combining a numerical band size with an alphabetical cup size. To determine the band size, wrap a soft measuring tape snugly around your ribcage just below the bust. Ensure the tape is level and not tight. Round the measurement to the nearest whole number, as this serves as the foundation for the bra’s support.
To find the cup size, measure around the fullest part of your bust, keeping the tape parallel to the ground. Subtract your band size from this measurement. Each inch of difference corresponds to a cup size (e.g., one inch equals an A cup, two inches a B cup, and so on).
A well-fitted sports bra should provide support without being restrictive. The band should rest firmly against the ribcage without digging into the skin or riding up during movement. The cups should fully cover the breasts, preventing spillage or gaps. Straps must offer support without placing excess pressure on the shoulders.
It’s important to check your bra size regularly, as factors like weight changes, hormonal fluctuations, and variations in training can affect the fit over time.
Wear a High-Impact Sports Bra When Needed
High-impact sports bras are designed with features such as wide, adjustable straps, firm bands, and encapsulated cups to distribute weight evenly and keep the breasts supported during intense activities.
The materials are breathable and moisture-wicking, managing sweat to keep the skin dry and reduce the risk of irritation or chafing. Selecting a sports bra that matches your activity level and body type helps protect your skin and enhance performance during workouts.
Apply Anti-Chafe Products
Anti-chafe products, including balms, creams, or sticks, are formulated to create a protective barrier over areas prone to friction. By forming a smooth layer, these products reduce rubbing and help protect the skin from irritation or breakdown during physical activity.
Solutions like ‘a body block to fight friction’ developed by the Avanza Skin team demonstrate the effectiveness of these formulations in preserving skin health.
How to Treat Sports Bra Chafing
- Cleanse the irritated area: Gently wash the affected skin with lukewarm water and a mild, fragrance-free soap to remove sweat, bacteria, and debris. Avoid hot water, as it can worsen irritation. Pat the area dry with a soft towel, ensuring all moisture is removed since dampness can slow healing.
- Apply a soothing moisturizer: After cleansing, use a hydrating moisturizer to calm the skin and support its natural barrier. Look for formulas containing aloe vera or chamomile, which are known for their soothing effects.
- Use anti-chafe solutions: To prevent further friction, apply a balm or an anti-friction stick that forms a protective barrier, allowing the skin to heal while avoiding additional irritation. Choose options designed for athletes, like those in Avanza Skin catalog, developed by dermatologists with experience in active lifestyles
- Let the skin breathe: Whenever possible, avoid wearing tight clothing or bras until the chafed area heals. Opt for loose, breathable garments to reduce friction and improve airflow, promoting faster recovery.
- Watch for signs of infection: Check the area for signs of infection, including increased redness, swelling, warmth, or pus. If these symptoms appear, consult a healthcare professional promptly.
Takeaway
Whether you’re preparing for a marathon, working out at the gym, or taking on a weekend hike, addressing the causes of chafing can greatly improve your experience. While it may seem like a minor inconvenience, chafing underscores the importance of using proper gear, adopting practical strategies, and understanding how our bodies interact with athletic equipment.
Remember, every workout is an opportunity to push boundaries and achieve new milestones.
