When selecting the perfect underwear, comfort, fit, and material should be your top concerns. Organic cotton is a popular growing choice, if you’re looking for a sustainable and comfy option, great for your health and the planet’s well-being.
To understand the reason behind this choice, let’s see the impact of conventional cotton production on the planet, what we mean by organic cotton, the advantages of transitioning to fabrics like organic cotton, and which brands offer the best organic cotton undies.
Not All Cotton Undies are Sustainable Underwear: Conventional Cotton is Not Organic Cotton
Cotton is one of the most widely used natural fibers in the world. We sleep on it, dry ourselves with it, and wear it almost daily. Even though it is so common and useful, how it is grown, harvested, and produced has significant environmental and social impacts.
Non-organic cotton farming relies heavily on synthetic pesticides and fertilizers, which pollute soil and water sources, harm wildlife, and contribute to biodiversity loss. Its agriculture is estimated to account for 16.1% of the world’s insecticide sales and 5.7% of global pesticide consumption. Every year, thousands of cotton farmers and their families endure the devastating effects of pesticide poisoning. Nearly 500 die from acute pesticide poisoning and many more suffer from chronic ill health, such as cancers and leukaemia, neurological diseases and reproductive problems, including infertility and miscarriages.
In addition, cotton farming is barely profitable for many small farmers. Some earn less than two dollars daily from their cotton due to a lack of support and training, often resulting in low yields and economic hardship. For example, just one bad harvest can plunge a farmer into debt, threatening their livelihoods and potentially causing serious mental health issues associated with the stressful lifestyle related to this environmentally degrading way of farming, often leading to tragic outcomes such as suicide.
If this is not sufficient, its impact on the planet is catastrophic. We’ll name just one example: water. It takes approximately 10,000 liters of water to produce one kilogram of cotton. In many cotton-growing regions, this water is sourced from rivers and lakes, leading to the depletion of vital water resources.
The Aral Sea, the world’s fourth largest lake in 1960, has shrunk to half its former size due to cotton irrigation practices started less than 40 years ago. In addition, the dyeing and finishing of cotton textiles involve toxic chemicals, which can pollute waterways and pose risks to workers and communities.
Made from Organic Cotton: Yes, Please!
Organic cotton is a natural fiber grown using methods and materials with a low environmental impact.
The aim is to build biologically diverse agriculture while replenishing and maintaining soil fertility, reducing toxic and persistent pesticides and fertilizers through methods with minimal environmental impact, such as crop rotation, hand-weeding, and natural pest control, and using less water than regular cotton farming.
Organic cotton certification is a rigorous process governed by international standards, such as the Global Organic Textile Standard (GOTS). This certification ensures that the cotton is grown, processed, and manufactured following sustainable and ethical practices, from the field to the final product, giving you the confidence that you’re making a responsible choice for your health and the environment.
Is Organic Cotton Sustainable Fashion?
Yes, it is! If you switch to organic cotton, you’ll reduce your environmental footprint and support more sustainable and ethical practices.
However, be sure to seek certifications and look at our brand guide for more information on organic cotton farming and the brand you’re shopping from. It is important to remember that organic cotton is a more sustainable solution than non-organic cotton, but it still doesn’t remove all environmental damage connected to carbon emission, transportation methods, and packaging along the supply chain, to name a few.
Choosing organic cotton is not just a sustainable choice but also a health-conscious one. Regular cotton textiles can retain pesticides and chemical dye residues, which may cause skin irritation and allergies. Data suggest that textile dye sensitivity is more common than previously believed. This is particularly concerning when it comes to undergarments, as they are in constant contact with some of the most sensitive areas of our body. Organic cotton, on the other hand, is free from these harmful chemicals, making it a safer option for people with sensitive skin or those prone to allergies.
Moreover, organic cotton is naturally breathable and moisture-wicking, crucial for maintaining all-day comfort and hygiene in underwear. The fabric allows for better air circulation, reducing the likelihood of bacterial growth, which can lead to infections, especially in warm and humid conditions. Its softness and breathability ensure comfort, while its hypoallergenic nature makes it safe for people with sensitive skin or allergies.
