Sweaty armpits can be more than just an annoyance—they can cause discomfort, embarrassment, and even impact your clothing choices. Whether you’re dealing with mild underarm perspiration or excessive sweating (hyperhidrosis), there are plenty of natural and effective strategies you can try to stay dry and fresh throughout the day.
Here are 12 lifestyle-friendly tips to help stop sweaty armpits and manage underarm perspiration.
Wear Breathable, Natural Fabrics
Synthetic fabrics can trap heat and moisture, worsening sweat. Instead, opt for breathable materials like organic cotton, bamboo, or linen, which allow your underarms to stay cooler and drier. Choosing looser cuts can also improve airflow and comfort. If you do sweat, dark colours hide sweat stains better than light pastels or greys.
Apply Deodorant at Night
Most people apply deodorant in the morning, but it can be more effective at night. Your sweat glands are less active during sleep, allowing active ingredients to absorb more deeply and work more effectively. If you’re using a natural deodorant, nighttime application helps it form a better protective layer for the day ahead.
Use Apple Cider Vinegar
Apple cider vinegar is known for its astringent and antibacterial properties. Applying it to clean underarms at night can help balance pH and shrink sweat glands, reducing wetness over time. Simply dab diluted apple cider vinegar (1:1 with water) onto underarms before bed, and rinse off in the morning.
Stay Hydrated
Believe it or not, dehydration can actually cause more sweating, as your body works harder to regulate internal temperature. Drinking plenty of water helps cool you from the inside out and may reduce the intensity of underarm perspiration during stressful or hot situations.
Limit Spicy Foods and Caffeine
Both spicy foods and caffeine stimulate your nervous system and can activate your sweat glands. If you notice a connection between your diet and sweaty armpits, consider tracking what you eat and scaling back on triggers.
Practice Stress-Reduction Techniques
Sweating isn’t always caused by heat—emotional sweating is triggered by anxiety, nerves, or stress. Deep breathing, meditation, yoga, or even a short walk outside can calm your nervous system and reduce stress-related underarm perspiration. Find out how stress affects sweating from Harvard Health.
Shave or Trim Underarm Hair
Excess hair under the arms can trap sweat and bacteria, making odour and moisture worse. Shaving or trimming can help reduce build-up, keep you feeling cleaner, and allow deodorants to absorb more effectively.
Change Clothes Regularly
Sometimes, preventing sweat buildup is as simple as keeping fresh clothes on hand. Changing out of a sweat-drenched top after a workout or humid commute can help you stay dry and odor-free for the rest of the day. Consider packing an extra shirt or set of clothes if your days are particularly active.
Balance Your Diet with Magnesium and B-Vitamins
These nutrients support your adrenal and sweat gland function. Low magnesium levels, in particular, have been linked to excessive sweating in some people. Foods to try include leafy greens, avocados, nuts, seeds, bananas, and whole grains.

Try Underarm Sweat Pads
Underarm sweat pads can absorb moisture before it reaches your clothes. They have been suggested by some experts as an effective temporary solution, especially if you’re transitioning away from antiperspirants. You can choose between disposable sweat pads (suitable for events) or reusable fabric pads for daily use.
Switch to a Natural Deodorant
While traditional antiperspirants block sweat glands using aluminium salts, they may interfere with your body’s natural detox process. Natural deodorants don’t stop sweat entirely but can help neutralize odour and reduce bacteria buildup that makes sweat smell worse.

Consult a Doctor for Persistent Sweating
If your sweaty armpits are interfering with daily life and home remedies aren’t helping, you might be dealing with axillary hyperhidrosis—a medical condition that causes excessive underarm perspiration. Your doctor may recommend prescription-strength antiperspirants (without fragrance), Iontophoresis (a mild electrical treatment), botox injections (which block sweat signals), or miraDry (a non-invasive, permanent sweat gland treatment).
These are aggressive solutions but can be life-changing for those with chronic sweating issues.
Create a Hygiene Routine That Works for You
At the end of the day, managing sweaty armpits is about finding a combination of lifestyle habits, natural remedies, and personal care products that fit your needs. Start with the small changes—better fabrics, diet tweaks, and natural deodorant—and layer in solutions like sweat pads or stress reduction if needed.
