In warm and humid places like Singapore, Malaysia, Thailand, and Vietnam, underwear care is not only about washing — it is also about drying, fabric freshness, and daily comfort. Humidity can make underwear take longer to dry, while frequent sweating and repeated washing can affect elasticity, softness, and breathability. Here are six common underwear washing mistakes to avoid, especially if you live in a humid climate.

You wash your underwear every day—but are you doing it wrong? Here are the mistakes that could be affecting your health.
Mistake 1: Using Hot Water
Boody advises using "cold water or lukewarm water" when washing underwear (Boody). Hot water can damage elastic fibers and cause shrinkage.
Mistake 2: Using Harsh Detergents
Many people use regular detergent loaded with fragrances. Columbia Pike Laundry recommends using "a gentle detergent" specifically for intimate wear (Columbia Pike Laundry).
Mistake 3: Not Using a Lingerie Bag
Toshiba warns against washing underwear with "socks and other clothes" (Toshiba). Use a mesh lingerie bag to prevent tangling and damage.
Mistake 4: Skipping the Rinse Cycle
Double rinse ensures all detergent residue is removed. Residue can cause skin irritation, especially for sensitive areas.
Mistake 5: Using Fabric Softener
Fabric softener coats fibers and reduces breathability. It can also irritate sensitive skin.
Mistake 6: Machine Drying
Air-dry whenever possible. Swag Boxers explains that "the use of hot water may lead to shrinkage or deterioration of elastic bands" (Swag Boxers).
