The myth that period underwear smells
Short answer: Period underwear does not smell on its own when it is worn and washed correctly. Odour usually appears if it is worn too long, not rinsed before washing or not dried completely.
Why the myth exists
Many people worry about smell when they first consider period underwear. The idea is that blood collects in the underwear instead of being removed with a pad or tampon. But menstrual blood smells very little when it is fresh. Odour only develops when it has been left for a while in warmth and moisture, where bacteria can get to work. The same is true of pads that are worn for too long, so the concern is not unique to period underwear.
Change at the right time
How long you can wear a pair of period underwear depends on how heavy your flow is and how absorbent the underwear is. On light days one pair can last a long time, while on heavy days it may be necessary to change during the day. Follow the maker's guidance and pay attention to how they feel. If they feel damp or heavy, it is time to change. See period underwear.
Rinse before washing
The most important step is to rinse the underwear in cold water as soon as you take it off. Cold water loosens the blood, while hot water can set it into the fabric. Rinse until the water runs fairly clear, then wash them in the machine with other clothes at the temperature on the care label. Do not use fabric softener, as it can leave a film on the fabric and reduce absorbency over time.
Drying
Period underwear has several layers in the gusset and takes longer to dry than ordinary briefs. Hang them with the gusset free so air can reach it. Avoid the tumble dryer unless the care label says otherwise, as heat can damage the layers. Underwear that is not completely dry can develop a musty smell, so make sure it is fully dry before it goes back in the drawer.
Everyday underwear
Outside your period, the same principles apply to ordinary briefs. Change them every day, wash them at the right temperature and let them dry properly. A fabric that absorbs moisture and lets it evaporate can feel fresher through the day than dense synthetics. See bamboo panties and bamboo underwear for women for everyday styles that suit different outfits.
When the smell changes
A faint smell during your period is normal. If you notice a new, strong or unusual smell, or if there is itching, stinging or discharge that is different from usual, it may be caused by an infection. That has nothing to do with the underwear. Talk to your doctor if you are unsure. It is a common question that doctors hear often, so there is no reason to hold back.
