Summer heat can be brutal, and one of the most common problems people face during scorching weather is underarm sweat and odor. Excessive sweating combined with bacteria can cause unpleasant smells, making us feel uncomfortable and self-conscious.

But don’t worry—keeping your underarms fresh and odor-free during hot days is easier than you think.

In this blog, we’ll explore the best ways to maintain clean, fresh underarms, focusing on practical tips and proven remedies that work even in the hottest weather.

Why do underarms sweat and smell?

Before we dive into solutions, it’s important to understand why underarms sweat and develop odor:

Sweat glands: Your body has two types of sweat glands — eccrine and apocrine. The apocrine glands, located in your underarms, produce sweat that contains proteins and fats. When bacteria on your skin break down this sweat, it causes odor.

Heat and humidity: High temperatures increase sweat production, creating a moist environment where bacteria thrive.

Poor hygiene: Not cleaning or drying your underarms properly can lead to bacterial buildup and foul smell.

Best Ways to Keep Underarms Clean and Odourless in Heat

1. Maintain Proper Hygiene

Daily washing: Wash your underarms thoroughly with a gentle antibacterial soap or body wash at least once daily, preferably twice in hot weather.

Exfoliate weekly: Dead skin cells can trap sweat and bacteria. Use a mild scrub or exfoliating cloth once a week to remove dead skin gently.

2. Use an Effective Antiperspirant or Deodorant

Antiperspirants: These reduce sweat production by temporarily blocking sweat glands. Choose one with ingredients like aluminum chloride for better sweat control.

Deodorants: These mask odor by killing bacteria or neutralizing smell. Some products combine both antiperspirant and deodorant functions.

Apply correctly: Apply on clean, dry skin, preferably at night, to allow better absorption.

3. Wear Breathable Clothing

Choose natural fabrics: Cotton, linen, and bamboo allow your skin to breathe, reducing sweat and bacterial growth.

Loose-fitting clothes: Tight clothes trap sweat and heat, increasing odor risk.

4. Keep Underarms Dry

After washing or sweating, dry your underarms completely before putting on clothes or deodorant.

Use absorbent wipes or talcum powder during the day if needed.

5. Try Natural Remedies

Lemon juice: Its natural antibacterial properties help kill odor-causing bacteria. Dab fresh lemon juice under your arms, leave for 10 minutes, then rinse.

Baking soda: Acts as a natural deodorizer by neutralizing pH and absorbing moisture. Mix with water into a paste and apply.

Apple cider vinegar: Helps balance skin pH and reduce bacteria. Dilute with water and apply gently.

6. Stay Hydrated and Eat Smart

Drinking plenty of water helps regulate your body temperature and reduces excess sweating.

Avoid spicy foods, caffeine, and alcohol, which can increase sweat production and body odor.

7. Shave or Trim Underarm Hair

Hair traps sweat and bacteria, making odor worse. Keeping your underarms shaved or trimmed can improve cleanliness and reduce smell.

8. Seek Medical Help for Excessive Sweating

If you experience excessive sweating (hyperhidrosis) that doesn’t improve with home remedies, consult a dermatologist. Treatments like prescription antiperspirants, Botox injections, or other therapies may help.

Final thoughts

Keeping your underarms clean and odor-free in scorching heat isn’t just about comfort—it boosts confidence and hygiene. By following the above tips, you can stay fresh all day long even during the hottest weather.

Remember, consistency is key. Simple daily habits like washing properly, using the right products, and choosing breathable fabrics can make a huge difference. If natural remedies appeal to you, try incorporating lemon juice or baking soda into your routine for an extra fresh boost.
