How often do you change your period underwear?

A Practical Guide to Staying Fresh, Dry & Leak-Free

Period underwear is a game-changer for many people who want comfort, leak protection, and sustainability during their menstrual cycle.
But one of the most common questions is:

👉 "How often should I change my period underwear?"

The answer depends on several factors — like your flow, the absorbency level of the underwear, and your daily routine.

⏱️ General Rule of Thumb:

Flow Level Recommended Change Frequency
Light Every 10–12 hours
Medium Every 6–8 hours
Heavy Every 4–6 hours
Overnight Up to 12 hours (only with heavy-absorbency underwear)

If you notice any wetness, discomfort, or smell, it’s a clear sign it’s time to change — even if it hasn’t been long.

🩲 What Affects How Often You Should Change?

1. Your Menstrual Flow
Everyone’s period is different. On heavier days, your underwear may reach capacity faster.

2. The Absorbency Level of Your Underwear
Some period underwear (like NYX Collection's 4-layer designs) can hold up to 3–4 tampons’ worth of blood. Others are designed only for spotting or backup for tampons/cups.

3. Activity Level
If you’re moving a lot or sweating, you may want to change more often to stay fresh.

4. Type of Day
At home, you may feel more comfortable wearing longer. At work or school, you may want to change to feel cleaner.

🧺 Should You Change Period Underwear More Than Once a Day?

Yes — many people change once in the morning and once before bed, especially on moderate to heavy flow days.
It’s totally normal to go through 2–3 pairs per day depending on how absorbent your pair is.

🧼 Don’t Forget: Proper Washing Is Key

To keep your underwear safe and reusable:

  • Rinse after use with cold water

  • Machine wash or hand wash using mild detergent

  • Air dry (avoid fabric softeners and dryers)

Most high-quality pairs last 2–3 years with good care!

✅ Final Thoughts

Changing your period underwear every 4 to 12 hours depending on your flow and activity level helps you stay:

  • Leak-free

  • Odor-free

  • Comfortable and dry

Invest in 2–5 pairs so you can rotate throughout your period.
