• Most tampons and pads usually remain safe for about five years when stored properly, but humid environments can significantly shorten that.
• The bathroom is one of the worst places to store tampons because steam and humidity create conditions for mold and bacterial growth.
• Cool, dry locations away from moisture and direct sunlight will keep period products in their best condition.

Most people grab a box of tampons, shove it under the bathroom sink, and don't think twice. Fair enough. The thing is, where and how you store period products affects whether they stay safe and effective until you use them.

At Cora, we want our products to actually work the way they're meant to when you reach for them, which makes storage worth a quick conversation.

Unopened tampons and pads generally have a shelf life of about five years, assuming they're stored in ideal conditions.

Menstrual cups can last up to a decade with proper care. Pads tend to hold up similarly to tampons, though the adhesives can degrade faster in heat.

The catch: that five-year window assumes the packaging stays sealed and the environment stays dry. Both of those assumptions break down for many people.

When it comes to storing your period products, keep the following tips in mind.

Linen closets, bedroom drawers, and cabinets away from the bathroom are ideal, as these are dry environments.

Keep tampons in their wrappers and pads in their individual sleeves until you use them. The packaging protects against dust, perfume, and other contaminants.

If you have to keep some in the bathroom for convenience, store them in a sealed plastic or glass container to limit exposure to steam and humidity.

Here’s a quick list of locations that might work against you when it comes to keeping your period products in good condition:

• Bathrooms with showers: Steam and humidity speed up mold growth.
• Cars: Heat and temperature swings break down adhesives and fibers.
• The bottom of your bag: Loose tampons get crushed wrappers, dust exposure, and friction damage.
• Direct sunlight: UV can break down materials over time.

If you spot any of these signs on your period products, it’s probably best to toss them: visible mold or discoloration, a damp or musty smell, a torn or compromised wrapper, or any visible debris on the product itself. When in doubt, throw it out.

• Unopened tampons and pads stay safe for about five years, but only if the packaging remains sealed and storage conditions stay dry.
• Cool, dry locations like linen closets or bedroom drawers — and keeping products in their original packaging — are the best ways to preserve period products.
