Clearing up doubts How often should you replace your underwear? Also, check the harms of wearing worn-out underwear, which becomes a reservoir for fungi and bacteria—a silent threat to intimate health.
Intimate health is a close-to-home matter that should not be overlooked, especially items worn in close contact with the body all day, such as "underwear." Many people tend to keep wearing their favorite underwear repeatedly until it tears or becomes too loose to wear. However, in reality, degraded fabric hides more serious dangers than meet the eye. Let's find out how often underwear should be replaced and what harms continuing to wear old underwear can cause to the body.
Medical studies and gynecological experts recommend replacing underwear every 3 to 6 months, or at the very latest within 1 year. Even though we wash underwear regularly with detergent or disinfectants after each use, some bacteria and microorganisms can still embed themselves in the fabric fibers, especially underwear that has been washed and worn for a long time until the fabric starts to degrade.
Wearing underwear past its usable life causes more than just discomfort; it can lead to chronic health problems such as:
1. A breeding ground for bacteria and fungi
Repeated washing and friction cause the fabric fibers to deteriorate and create tiny gaps, allowing bacteria, fungi, and protein stains from secretions to embed deeply. Normal washing may not completely eliminate these microbes.
2. Increased risk of infections in intimate areas
Wearing underwear that accumulates germs over time raises the risk of bacterial vaginosis in women or infections in the groin area in men, which can escalate to sexually transmitted diseases or fungal infections in the groin.
3. Irritation and skin diseases
Degraded underwear often has stretched elastic bands that no longer fit snugly or stiffened fabric. Wearing such underwear causes friction against sensitive skin areas, leading to redness, itchy rashes, and dermatitis.
4. Persistent musty odor
Even after washing and drying in sunlight, old underwear with degraded fibers tends to retain moisture and unpleasant odors, making it prone to mustiness during the day, especially in Thailand's hot and humid climate with heavy sweating.
If you're unsure whether your underwear is over 6 months old, look for these signs of deterioration:
Replacing underwear every 3-6 months is not a waste but an investment in good intimate hygiene. Persisting with worn-out underwear can lead to rashes, bad odors, and dermatitis, costing more time and money in treatment than the price of new underwear.
