Underwear Hygiene: How Often Should You Change Your Underwear?
The Hygiene Rule: Most experts recommend changing underwear at least once every 24 hours. However, if you exercise or live in a humid climate, you should change immediately after sweating. Bacteria thrives in damp environments, so switching from moisture-retaining cotton to moisture-wicking Micro Modal Air is the single best upgrade for hygiene.
Underwear hygiene plays an important role in comfort, skin health, and overall cleanliness. Because underwear sits closest to the body, choosing the right fabric and changing it regularly helps reduce moisture buildup, odor, and irritation.
Why Underwear Hygiene Matters
Throughout the day, underwear absorbs sweat, oils, and dead skin cells. Poor hygiene habits can lead to discomfort, "jock itch," and skin irritation. Clean, breathable underwear helps maintain a healthier environment.
- Reduces moisture and odor buildup.
- Helps prevent fungal infections and rashes.
- Improves daily confidence and comfort.
The Fabric Hygiene Scale
Fabric plays a major role in how underwear handles bacteria. Some fabrics trap it; others repel it.
| Fabric | Moisture Control | Hygiene Rating |
|---|---|---|
| Polyester | Traps Heat | Low (Retains Odor) |
| Cotton | Absorbs & Stays Wet | Moderate |
| Micro Modal Air® | Instantly Wicks | Very High (Stay Fresh) |
Best Hygiene Habits for Men
Keep your routine fresh with these simple rules:
- The "Sweat Rule": Change underwear immediately after workouts. Do not sit in damp gym shorts.
- The Wash Rule: Wash underwear after every single wear. Use mild detergent and avoid fabric softeners, which can clog the breathable fibers.
- The Rotation Rule: Replace underwear every 6 to 12 months. If the elastic is frayed or the fabric is permanently stained, throw it out.
