Summer can be glorious but let’s be honest, it also brings sweat, body odor, and sticky discomfort. Whether you’re power-walking under the sun or just trying to survive a heatwave, your underwear, clothing, and deodorant choices matter more than you think. If you’ve ever wondered why you sweat more in summer, how to control body odor naturally, or what underwear keeps you cool, this comprehensive guide has you covered.
Here’s how to stay dry, fresh, and confident when temperatures rise.
What Type of Underwear Should You Wear in Summer?
Underwear is the first layer of defense between your skin and sweat. During hot weather, it should be:
- Breathable
- Moisture-wicking
- Soft and non-irritating
- Supportive without being tight
Top summer-friendly underwear fabrics:
- 100% Cotton – Natural, breathable, and moisture-absorbing
- Bamboo – Antibacterial, soft, and temperature-regulating
- Modal – Lightweight and breathable with a silky feel
- Micromodal or Tencel blends – Sustainable and quick-drying
- Mesh panel underwear – Improves airflow in high-sweat areas
Avoid polyester, nylon, or lace-based underwear for daily wear in summer. They tend to trap heat and increase the risk of odor, yeast infections, or skin irritation.
Tip: Change your underwear twice a day during extreme heat or after workouts.
Why Does Sweating Increase in Summer?
Sweating is your body’s natural cooling mechanism. When your internal temperature rises, your brain signals your sweat glands to release moisture onto your skin. As it evaporates, it cools you down.
In summer, sweat production increases due to:
- Higher ambient temperatures
- Increased physical activity
- Humidity that prevents sweat from evaporating
- Tight or synthetic clothing that traps heat
- Stress or anxiety, which activates apocrine glands
While sweat itself is odorless, it creates a breeding ground for bacteria, which break it down and cause body odor, particularly in the underarms, groin, and feet.
How to Reduce Body Odor in Summer
The goal is not to eliminate sweat altogether (that’s unhealthy), but to manage moisture and bacterial buildup effectively.
Top strategies to reduce odor:
- Shower regularly, especially after sweating
- Use antibacterial soap for underarms and groin area
- Dry thoroughly, as dampness encourages bacterial growth
- Wear breathable clothing and underwear
- Apply deodorant or natural alternatives
- Stay hydrated – sweat becomes more pungent when dehydrated
- Avoid spicy foods, garlic, and alcohol, which can intensify body odor
Laundry tip: Wash clothing with baking soda or white vinegar to remove trapped odor from synthetic fabrics.
Are There Alternatives to Deodorants?
Yes if you’re concerned about conventional antiperspirants, especially those containing aluminum, there are natural alternatives that can help control sweat and odor.
Popular natural sweat-control ingredients:
- Witch hazel – A natural astringent that tightens pores
- Baking soda – Neutralizes odor-causing bacteria
- Apple cider vinegar – Balances skin pH and reduces odor
- Aloe vera gel – Soothing and antibacterial
- Coconut oil + tea tree oil – Antifungal and odor-fighting blend
- Arrowroot powder or cornstarch – Absorbs moisture
You can find these ingredients in natural deodorant sticks or DIY sprays and pastes.
Are Aluminum-Based Deodorants Harmful?
Aluminum salts in antiperspirants work by blocking sweat glands, reducing underarm moisture. While effective, they’ve raised concerns due to:
- Potential skin irritation, especially when used after shaving
- Links (though unproven) to breast cancer and Alzheimer’s, which remain debated
- Disruption of natural detoxification, as sweat helps eliminate toxins
Current scientific consensus is that aluminum in deodorants is safe for most people when used correctly. However, those with sensitive skin or allergic reactions may prefer to avoid it.
Tip: Always read labels. “Aluminum-free” doesn’t mean that many natural options offer long-lasting odor control.
Which Clothes Help Reduce Sweat in Summer?
Choosing the right clothing is just as important as deodorant when it comes to managing sweat.
Best sweat-reducing summer fabrics:
- Linen – The king of airflow and breathability
- Cotton – Especially in loose weaves, for everyday wear
- Chambray – A lighter alternative to denim
- Tencel (Lyocell) – Soft, cooling, and sustainable
- Moisture-wicking athletic fabrics – Great for workouts and travel
Clothing tips to reduce summer sweat:
- Choose loose-fitting tops and bottoms that allow circulation
- Wear light colors to reflect the sun’s rays
- Avoid synthetic blends that trap heat
- Opt for sleeveless or short-sleeve tops
- Use anti-chafing shorts or powders in thigh and groin areas
For feet: Choose open-toed sandals or mesh sneakers and moisture-wicking socks to reduce foot odor and fungal growth.
Sweat-Savvy Habits for a Cooler, Fresher Summer
- Shower in lukewarm water, not cold it cools you more effectively
- Exfoliate underarms and groin area weekly to remove dead skin and reduce odor
- Keep body wipes in your bag for quick refreshes during the day
- Sleep in lightweight, breathable pajamas
- Sprinkle baking soda or talcum-free powder on sweaty areas before heading out
Remember: Sweating is natural, but managing it smartly makes summer living a lot more enjoyable.
