Maintaining proper personal hygiene starts with small daily habits, and one of the most important—yet often overlooked—is changing underwear regularly. Many men search online asking: How often should men change their underwear? The answer is simple, but the reasons behind it are important for health, comfort, and confidence.

In this guide, we’ll explain how often men should change underwear, what happens if they don’t, and expert tips to maintain intimate hygiene.

How Often Should Men Change Their Underwear?

Men should change their underwear at least once every day.

This is the minimum recommendation from health and hygiene experts. Underwear is worn closest to the skin and is exposed to sweat, bacteria, dead skin cells, and body oils throughout the day. Wearing a fresh pair daily helps keep the intimate area clean, dry, and odor-free.

When Should Men Change Underwear More Than Once a Day?

While once a day is enough for most people, there are situations where men should change underwear twice or more in a day:

✔ After Exercise or Sports

Sweat accumulation during workouts creates a breeding ground for bacteria and fungi. Always change underwear immediately after gym sessions, running, or sports.

✔ In Hot & Humid Weather

In climates like India, excessive sweating is common. Changing underwear more than once helps prevent rashes and infections.

✔ Heavy Sweating or Body Odor

Men who sweat excessively should change underwear whenever it becomes damp.

✔ Skin Sensitivity or Infections

If you experience itching, redness, or fungal infections, doctors recommend changing underwear more frequently and keeping the area dry.

Why Is Changing Underwear Daily Important?

Not changing underwear regularly can lead to several hygiene and health issues:

• Bad odor
• Skin irritation and rashes
• Fungal infections (jock itch)
• Bacterial growth
• Discomfort throughout the day

Daily change reduces moisture and friction, keeping the intimate area healthy.
