Why You Should Consider Period Underwear as an Alternative to Pads and Tampons

If you hate the waste or the cost of buying disposable menstrual products, you’re definitely not alone. No one likes spending all those pink tax dollars every month just to literally roll them up and throw them in the trash.

If you’re ready to make the switch to a reusable alternative, it’s time to consider period underwear. Here are all the reasons they might be a more comfortable, reliable, less wasteful option for your period. 

The Problem With Disposables

First things first, there’s absolutely nothing wrong with using pads and tampons during your period if you choose to. For many people, for instance folks with disabilities, disposable period products might be the best or most accessible or available option. 

That said, pads and tampons do have a number of downsides compared to reusables. Here are some of the big ones to consider if you’re thinking about making the switch.

Extra Waste

You probably already know that pads and tampons are pretty lousy for the environment. Every year in the U.S. alone, around 12 billion pads and 7 billion tampons end up in landfills. 

That’s not including all the boxes, wrappers, applicators, and instruction manuals that add to the load. And, let’s be real: those stats don’t begin to factor in the wads of toilet paper we hide our used pads and tampons in.

Risky Business

Besides environmental concerns, tampons are also famous for posing a risk of Toxic Shock Syndrome (TSS). You know, that rare but potentially fatal bacterial infection you’ve read about in all the instruction manuals. 

Your chances of getting TSS are pretty low, but it’s still worth considering—especially for longer-wear use. Tampons can also make you more prone to yeast and fungal infections, and they can also just generally be a little uncomfortable.

Frequent Changes

Disposable pads are safer, but they can still increase the risk of yeast infections or cause irritation and itchy rashes (contact dermatitis). Even if they’re not causing a reaction, you still know that uncomfy feeling when they migrate to the wrong place in your underwear. 

To prevent leakage and itching, some people report changing pads as often as every hour—far from the eight hours recommended on the package. The all-day guarantee of most disposable period products is pretty far from how they’re actually used.

Bad-for-You Chemicals

Finally, many pads also contain plastics and other harmful chemicals that could impact reproductive health, and tampons have been found to contain arsenic and lead. Scientists are still working to understand the long-term impacts of these findings, but you may feel more comfortable going with another period solution.

Think of your favorite pair of everyday underwear – that's exactly how Leakproof underwear feels. They're so comfortable that you might forget you're even wearing them.

Simple, Stress-Free Care

No complicated washing routines here. Just toss them in with your regular laundry (cold wash and lay flat to dry), and they're ready to use again. Start with just a couple of pairs to try it out and go from there. Plus, think about how much simpler your bathroom cabinet will be without all those boxes of disposable products.

Always On Hand

Imagine never having to stuff your purse with emergency supplies or ask a friend for a spare tampon. No more midnight runs to the drugstore or moments of panic when you realize you're out of pads. Period underwear gives you one less thing to worry about – they're already in your drawer, ready whenever you need them.

With period underwear, you're always prepared and always comfortable.
