Did you know it’s estimated that a woman will use approximately 11,400 pads throughout her lifetime? Each of these pads are disposable, which means they end up in a landfill.

Pads are typically made from plastics, cotton, wood pulp and synthetic fibers. Since some of these components are synthetic, the entire pad will not break down. That means the pad you wore when you were a teen is probably still around today, sitting in a landfill.

How to Use Period Underwear: The Ultimate Guide to Period Panties

Some disposable pads also include artificial fragrances and synthetic chemicals into the mix, which may cause allergic reactions.

Tampons aren’t much better: During the average 40-year span that a person typically spends menstruating, an individual uses more than 9,000 tampons.

That’s why I co-founded Kayaness, a sustainable period company, with Shleby Orme, a sustainable lifestyle YouTuber who happens to be one of my best friends.

Period underwear is a reusable alternative to pads and tampons, but not all period undies are created equal.

Kayaness is committed to creating high-quality reusable items with ethical manufacturing, recycled and reclaimed materials that undergo rigorous testing for safety, and building products that are made to last.

If you’re considering switching over to period underwear but don’t know where to start, here’s a guide to period panties and how to use period underwear.

How to Use Period Underwear: The Ultimate Guide to Period Panties

what is period underwear?

Period underwear are undergarments you wear during your menstrual cycle to take the place of disposable pads and tampons. They are constructed to look and feel like regular underwear.

Period panties have extra layers and specific fabrics that line the crotch area. This enables them to absorb menstrual blood.

Period panties can be washed and then re-wore on repeat. They are a reusable option that can be worn all throughout your period, varying from heavy to light days.

why switch to period underwear?

There are two main reasons to switch to period underwear: Reducing waste and saving money. Let’s look at each a little more in-depth.

period underwear helps the environment

It’s estimated menstruating women will go through more than 11,000 pads in their lifetimes. Disposable period pads may contain up to 90% plastic, which means when they’re discarded and sent to a landfill, they take hundreds of years to break down into tiny pieces, aka microplastics.

Period products also have excessive plastic packaging: A 12 pack of pads is wrapped in plastic film, and each pad is individually wrapped in plastic (for sanitary purposes). Plastic film cannot be recycled via curbside recycling in most areas.

Additionally, pads are made in factories, which are often powered by fossil fuels. It takes a lot of energy to transform raw materials like cotton and crude oil into useable products. Not to mention both conventional cotton and plastic have negative impacts on the environment.

Conventional cotton, not organic cotton, is frequently used in most period products. It is a water-hungry plant and heavily sprayed with pesticides that can pollute groundwater.

Each of these materials has their own carbon footprint individually (you can learn more about cotton’s carbon footprint here). But plastic must be transformed from crude oil into moldable plastic which takes up a lot of energy, water and resources.

A year’s worth of disposable pads and tampons for one person produces 8.9kg of CO2 emissions, the same as charging a mobile phone more than 1000 times.

That’s why Kayaness period panties are made from organic cotton and recycled polyester. This, paired with the fact they’re reusable, dramatically cuts down on their carbon footprint.

period underwear save money

Using disposables adds up over time. Let’s assume a person menstruates for 40 years and buys a $8 pack of disposable pads every month (excluding tax). That adds up to $3,840 over a lifetime, $96 a year.

This is likely an underestimate as the cost of menstrual pads, the taxes, and frequency of purchase can vary. For example, if you have a heavy flow, you may find yourself purchasing two packs instead of one per month.

That said, let’s look and see how much period panties will save you. Upfront, period underwear will cost more: For 5 pairs of Kayaness’ high waist briefs, it would cost $160 without tax.

However, if you use and take care of them for 2 years, that’s $192 saved based on the prior example above. At that point, the period underwear would’ve already paid for themselves and then some.

If you use them for five years, that’s $480 saved: Think of all the matcha lattes that could go towards instead!

how to use period underwear: a simple step-by-step break down

If you’re interested in trying out period panties but feel intimidated, here’s how to use them. Hint: It’s really simple!

  1. Order your period panties (we’ll talk about finding the right fit for you below).
  1. Wash them before your first wear. This can be in the washing machine (done on delicate) or handwashing, but always let it air dry. More instructions on how to wash your period panties are given below.
  1. When your period starts, just slip on your period underwear like normal panties. Depending on your flow, you can wear these for several hours. You may even be able to wear them all day, if your period is light enough. However, you should make it a point to change after 24 hours into a fresh pair.
  1. Change into a fresh pair of period undies and remove/clean the soiled ones. Repeat this process until your period is over!

how to wash period underwear

To clean your period underwear, there are a few steps you must take:

  • After you remove your period underwear, soak or rinse them in cold water. Do this until the water runs clear.
  • If using a washing machine, wash them on a delicate or gentle cycle with a mild detergent. To make your underwear last, consider handwashing in the sink.  
  • Don’t put them in the dryer, let them air dry by laying the underwear flat or hang drying them. You can even improvise and use coat hangers to hang them up to dry. 

finding the right fit

At Kayaness, we offer two styles of period underwear: High waisted briefs and boyshorts. Both these styles provide ample coverage, all while prioritizing comfort. We also offer sizing from XS to 4XL, so there’s something for everyone.

faqs

do you wear a pad with period underwear?

You don’t have to wear a pad with period underwear, unless you want to. It also depends on your flow: If you’re a heavy bleeder, you may prefer a little extra protection.

However, Kayaness underwear offers heavy absorbency and can hold up to 3-4 regular tampons worth of flow. This will last for hours.

Can you use period panties for postpartum bleeding?

Yes, you can use period underwear for postpartum bleeding. However, during the beginning of it, you may want to pair them with pads for fuller coverage.

Can you swim in period panties?

There are specific period swimwear brands out there for this purpose. Generally speaking, a reusable menstrual cup or organic tampon is recommended for swimming on your period. 

how often should you change your period underwear?

On average days, it’s good to change your period underwear at least once every 8-12 hours. However, it will entirely depend on your flow: If you have a heavy flow, you may need to change your pads more frequently.

how many pairs of period underwear do you need?

How many pairs of period underwear you need will depend on your unique flow.

If you’re new to period underwear, consider investing in at least two pairs to wear on your average-to-lighter days. This will let you try them out and get a feel for what works for your body.

You could also use period underwear only at night to have comfortable, fuller coverage.

If you’re committed to fully transitioning to period underwear, having about 8-10 pairs of period undies should be enough.

So, will you be making the switch to period underwear? Let me know in the comments!

Outdoor Projects You Can DIY for Almost Nothing

Published

on

It always strikes us as amusing how many DIY projects you see online that seem to require more time and more money than it would take to simply buy the thing they’re trying to DIY in the first place. Are we missing the point?

We think that doing things ourselves and taking back the power to create instead of simply consuming is absolutely vital to the green movement. But if you don’t already have the materials and spend a lot of money purchasing craft supplies, does it really make sense to DIY?

These eight projects are true do-it-yourself masterpieces. One-of-a-kind outdoor projects you can make for almost nothing, with supplies you most likely already have or can easily pick up second hand for a song. Roll up your sleeves and let’s get started!

1. Teapot/Teacup Bird Feeder

Do you have one of Grandma’s old tea sets lying around that doesn’t quite fit into the sleek modern aesthetic you’ve been cultivating? Put it to great use by feeding the birds in your area — in style.

Thrift stores are always awash in old china, so if you don’t already have the old tea set, consider going wild and spending a few bucks for this DIY delight. You’ll find blogger Dinah Wulf’s instructions for the teacup bird feeder at DIY Inspired.

Safety note: Use sturdy twine or cord — not chain — to hang the feeder. Birds can catch their toes in chain links, which causes serious injury. The National Audubon Society also recommends cleaning seed feeders every two weeks (more often in hot, humid weather) by scrubbing with soap and water and soaking in a 50-50 vinegar-water solution to prevent the spread of avian disease.

2. Gardening Tool Storage

What on earth do you do with those rusty-as-heck, old-school garden rakes hanging around your garage? Well, if you’re any sort of DIY genius, you press them into service as a gardening tool holder.

The original inspiration for this project came from Beth Logan at Artstuff Ltd., whose blog has since gone offline. For a current walkthrough, see the Repurposed Rake Tool Rack tutorial at DIY n Crafts (project #14 in their roundup of 25 ways to reuse old garden tools). The concept is embarrassingly simple — remove the rake handle, mount the head tines-out on a fence or garage wall, and use the tines themselves as hooks for trowels, gloves, and pruners — but eye-catching enough to make you look like a DIY pro.

3. Bottle Tree

Do you like wine? No, I mean do you really like wine? Do you want a reason to drink more of it? And does your garden need a cute border? This sustainable, upcycled garden border may be just the project for you. You might have to expand your drinking list to include bottles of various shapes, sizes, and colors — but variety is the spice of life.

When friends ask how you managed to collect so many bottles, just laugh gaily and then distract them with your dainty teacup bird feeder. The bottle tree tradition itself runs deep — Mississippi garden writer Felder Rushing traces the practice back through African American Southern folk art and, by his own research, as far as ancient Egypt and Mesopotamia. See his bottle tree gallery and history for inspiration, or jump straight to his how-to guide for building one out of a cedar snag, rebar, or just about anything else.

4. Colorful Outdoor “Tiles”

If your backyard isn’t perfectly landscaped and manicured, with an impeccably tiled “outdoor living space,” don’t despair. You can use up all those half-empty paint cans and create a Pinterest-worthy colorful backdrop for evenings spent clustered around a fire or barbecue.

Pop a few coats of paint on cement tiles and you have a one-of-a-kind flooring solution. If you rent, the same effect could be achieved on a more temporary basis by letting the kids go wild with sidewalk chalk and create a mosaic masterpiece. Check out Elsie’s Painted Patio Tiles at A Beautiful Mess for the back story on this DIY idea. (Heads up: the original author noted she had to touch up the paint each spring in Missouri winters — a porch and patio floor enamel will hold up better than wall paint.)

5. Home Sweet Gnome

Okay, this one might be the least practical idea of the bunch, but that may be why I love it oh so much. If you have a stump in your backyard and you’re not willing or able to pay the truly insane amount it costs to have it ground down and removed, how about making it into a little gnome home? This is the perfect outdoor project if you have small children in your life.

Construct the trappings of a little house — door, windows, winding garden path — from found objects or natural materials, and affix them to the stump. Bonus points if you don’t tell the kids about this particular DIY project and allow them to simply stumble upon it one day in the garden. My mind would have been blown if I had come across one of these as a seven-year-old. For a step-by-step build, see this Gnome Tree Stump Home tutorial on Instructables.

Safety note: Don’t use an angle grinder to gouge windows or doors into a stump. Use a chisel and mallet for shallow detail work, or attach decorative pieces (driftwood, bark, polymer clay) to the outside instead.

6. Mosaic Stepping Stones from Broken China

Every household eventually accumulates a small graveyard of chipped mugs, a single survivor from a four-piece dinner set, or a beloved teapot with a hairline crack. Rather than tossing them — broken ceramics generally aren’t accepted in curbside recycling — embed them in concrete stepping stones for a garden path that’s genuinely one of a kind.

This pairs beautifully with the teacup project above: any teacups that don’t make it past Project #1 (you will break a few) can come back as paving. The DIY mosaic stepping stones tutorial at Gardening.org walks through the full process — breaking ceramics safely inside a drop cloth, sizing pieces to half-inch to one-inch fragments, pressing them into wet concrete, and sealing the surface so sharp edges don’t cause injury underfoot. Basic mold options include an old cake pan, a plastic plant saucer, or a purpose-built stepping stone form from a craft store.

Safety note: Wear safety glasses and heavy gloves when breaking ceramics. Once cured, run a finger over the surface to check for protruding edges and file or sand any down before placing the stone where bare feet might land.

7. Vertical Pallet Herb Garden

Shipping pallets are one of the world’s most abundant near-free materials. Small businesses, garden centers, and feed stores often have stacks of them out back, and asking politely beats the alternative of seeing them landfilled. Mounted vertically against a sunny wall or fence, a pallet becomes a stacked planter that holds enough herbs to keep a kitchen in basil, thyme, parsley, and chives all season.

Grit Magazine published a clear how-to for a vertical pallet planter — line the back and sides with landscape fabric or heavy plastic to hold soil, fill through the slats, and plant each gap as its own row. The gaps act as natural divisions, so different herbs don’t fight for the same root space.

Safety note: Use only heat-treated pallets for anything edible. Look for the IPPC stamp with the letters HT (heat treated) and avoid any stamped MB (methyl bromide — a fumigant restricted under the Montreal Protocol). Unstamped pallets are unknowns; skip them for food crops. The same heat-treated pallets are fine for ornamental flowers either way.

8. Punched Tin Can Lanterns

Steel food cans — soup, tomato, coffee — are one of the most recyclable materials on Earth, but the recycling-then-buying-something-decorative loop has plenty of slack in it. With nothing more than a hammer, a few nails of varying sizes, and the freezer, an empty can becomes an outdoor lantern that throws constellation patterns across a patio at dusk.

HGTV’s tin can lantern tutorial covers the trick that makes this project work: fill the can with water and freeze it solid before punching, so the ice supports the can wall and prevents denting. Sketch your pattern on paper, tape it to the frozen can, punch through with a nail at each marked dot, and let the ice thaw. Drop in a battery tealight (much safer outdoors than a real flame) and group them along a walkway or down the center of an outdoor table.

The Point of All This

None of these projects requires you to buy more than a tube of waterproof adhesive, a bag of concrete, or maybe a stepping stone mold. The materials — chipped china, leftover wine bottles, empty cans, a forgotten pallet, an old rake — are already in your house or someone else’s. That’s the point. The greenest project is the one that uses what already exists, and the best part is that yours will look like nobody else’s.

Best of Sustainability In Your Ear: Author Nadina Galle on The Nature of Our Cities

Published

on


More than half the world’s population—4.4 billion people—live in cities today. That number is expected to rise to 80% by 2050. Our guest, Nadina Galle, is a trailblazing ecological engineer and author of The Nature of Our Cities. She is an ecological engineer who studies the intersection of nature and technology in urban environments. Nadina developed the concept of an Internet of Nature (IoN) that uses tools like artificial intelligence, automation, and sensors to support and enhance ecosystems within cities. Nadina’s book offers a transformative perspective on how urban spaces can be reimagined in the face of climate change and sprawling development. She shares the inspiring story of the Groene Loper project in Maastricht, Netherlands, where soil sensors were deployed to monitor tree health. The results were remarkable, with trees supported by this technology growing up to three times larger than those without it. This is a powerful example of how technology can not only protect trees but also transform urban spaces into healthier, greener environments.

Nadina Galle, an ecological engineer and author of The Nature of Our Cities, is our guest on .

From fire and the wheel to the reinforced concrete frames that define modern buildings, we are surrounded by technology. We tend to forget that technology emerged in response to nature — too often, we treated nature as the enemy, the chaos to be contained instead of recognizing that nature’s cycles and changes are the harmony we need to join to sustain society. The loss of any semblance of natural patterns, which ultimately leads to the depletion of the resources necessary for life, has inevitably led to the collapse of previous major civilizations. Modern society has more runway than previous societies because we have created a global economy, but that risks an even greater fall for our species when the ecological underpinnings of our prosperity collapse. The Nature of Our Cities, is a powerful, straightforward, and emotionally resonant book to help you think through your role and choices in the restoration of nature. You can find it on Amazon or Powell’s Books.
