As an item of clothing that lays closest to our bodies that we wear daily, we owe it to ourselves to invest in underwear that is good not only for our body but also for the environment.

One of the best options that ticks both boxes are organic cotton underwear.

Benefits of using cotton underwear

Although the market is now flooded with synthetic fabrics like rayon, viscose, and spandex, cotton is undoubtedly the best material for underwear.

The high absorbency of cotton prevents yeast infections by not allowing moisture to accumulate.

Synthetic materials can be restrictive and often chafes, breaking your skin around sensitive areas.

By being breathable, cotton underwear also prevents odor build-up.

Moisture trapping leads to the build-up of bacteria which can lead to some smelly conditions down there.

There is a certain comfort that you seek from underwear which cotton can provide.

However, just using cotton underwear is not enough.

Conventional cotton is grown and processed just as unsustainably as synthetic fabrics, which makes non-organically grown cotton, not the best option. 

What harmful chemicals in underwear should consumers be careful of?

Unfortunately today a lot of fabrics are usually heavily doused with chemicals for processing.

These chemicals can still linger in the finished product.

The first place these chemicals transfer would be to your skin in the most sensitive areas of your body.

These chemicals can easily enter your body when in intimate clothing like underwear.

Carcinogenic chemicals are often used to bleach fabric and add other properties like making the fabric wrinkle-free, pest and stain-resistant, or water repellent.

Some of these chemicals include petrochemicals which cause skin suffocation, headaches, and respiratory problems, perfluorocarbon which causes kidney failure and formaldehyde which causes lung cancer and dermatitis.

Some of the chemicals can also affect your reproductive cycle.

To avoid all these problems, why not opt for a greener, cleaner, more comfortable choice that has less of an environmental impact?

Why is organic cotton a better choice for underwear?

By choosing organic cotton underwear instead of synthetic materials or even conventional cotton, you are protecting the planet as well as your skin.

Pure organic cotton is hypoallergenic. Organic cotton is less processed than conventional cotton which also means less dangerous chemicals along the way.

As it is completely free from chemicals that can cause rashes, it feels much better on the body and prevents you from catching anything down there.

With organic fabric, the breathability of the fabric does not allow heat to be trapped close to your body and your sensitive parts stay fresh and dry. 

Environmental benefits of organic cotton

Apart from the benefits that organic cotton has for our bodies, it is also a much better choice for the environment.

Normal cotton is a crop that is highly intensive in terms of its water requirement, pesticide, and fertilizer use. Since growing organic cotton is much less intensive (organic cotton uses 91% less water, 46% less carbon dioxide, and 61% less energy than conventional cotton), it emits 94% less greenhouse gas emission compared to conventional cotton. 

Only organic or composted manure is used as fertilizer for growing organic cotton.

By eliminating toxic chemicals, organic cotton growing also increases soil health as well as promotes more biodiversity in the system.

In this way, you buying organic underwear encourages the healthy cultivation of the soil, saves gallons of water, and avoids harsh chemicals!
