Why does it feel uncomfortable to wear tighter underwear?

Uncomfortable wearing tight underwear is usually related to local compression, poor breathability or skin sensitivity. Underwear that is too tight may affect blood circulation, cause friction on the skin, or breed bacteria, causing discomfort.

Underwear that is too tight can cause constant pressure on the perineum and affect blood circulation in the area. In men, compression may cause the temperature of the testicles to rise, interfering with sperm production. In women, friction may irritate the vulvar mucosa, causing itching or redness. Underwear made of chemical fiber has poor breathability, and accumulation of sweat can easily breed bacteria or fungi, increasing the risk of infection. Some people are allergic to dyes or materials and may develop contact dermatitis after contact, manifesting as erythema or papules.

In a few cases, pathological factors need to be considered. Men who wear tight underwear for a long time may induce varicocele and a swollen feeling in the scrotum. Women may develop Bartholin gland cysts due to friction from tight underwear, accompanied by local swelling and pain. Diabetic patients wearing tight underwear may aggravate perineal discomfort due to peripheral circulation disorders. When you have skin conditions such as jock itch or eczema, the friction of tight underwear can aggravate the existing symptoms.

It is recommended to choose loose underwear made of pure cotton or modal. The waist and trouser legs should be moderately elastic to avoid pinch marks. Change underwear daily and wash with mild detergent to avoid using softener residue that may irritate the skin. Newly purchased underwear should be washed before wearing to reduce exposure to chemicals. Change wet underwear promptly after exercise to keep the perineum dry. If the discomfort lasts for more than 3 days after adjusting the underwear or if abnormal secretions, skin damage, etc. occur, you need to go to a dermatology or urology department to investigate the disease factors.
