1.Avoid chemical fiber blends:Although materials such as polyester fiber are cheap, they are easy to breed bacteria in hot weather. Xiaohongshu reviews show that the odor of these underwear is more obvious after sweating.

2.Choose dark colors carefully:Weibo polls show that 73% of users believe that light-colored underwear (especially white and nude colors) feel cooler than dark-colored underwear because dark colors absorb heat better.
3.Pay attention to the crotch structure:Zhihu's highly praised answer emphasized that the crotch of three-dimensional tailoring + honeycomb mesh design (such as some sports brands) is 40% more breathable than the flat design.
| Usage scenarios | Recommended material combinations | Washing frequency |
|---|---|---|
| Sitting for a long time in the office | Modal + crotch silk lining | Changed daily |
| gym training | Coolmax+ antibacterial treatment | single use |
| outdoor hiking | Bamboo fiber + seamless design | Replace every 4 hours |
1.Medical opinion:Dermatologist Dr. Wang suggested on Douyin that those who sweat a lot should choose materials with a neutral pH value (such as some bamboo fiber models) to avoid damaging the acid-base balance of the private parts.
2.New technological products:Recently, graphene underwear has appeared on Taobao crowdfunding. Laboratory data shows that its thermal conductivity is 200% higher than cotton, but the current price is on the high side (unit price ¥150+).
3.Eco-friendly options:Weibo's hot search #sustainablewear# mentions that biodegradable eucalyptus fiber underwear has become a new favorite in Europe and the United States, and niche brands have been introduced in China.
Summary:When choosing underwear, you need to consider the amount of sweat, activity scene and budget, giving priority to breathability and antibacterial properties. Regular replacement (3-6 months recommended) and correct washing (avoiding softeners) are equally important. If skin discomfort persists, seek medical attention promptly to check for allergens.
