About This Product
Coyuchi Organic Cotton Sheet Set is made from GOTS-certified (Global Organic Textile Standard) organic cotton, ensuring the cotton was grown without synthetic pesticides or fertilizers and processed without harmful chemicals at every stage. The sheets are free from formaldehyde, synthetic dyes, and chemical treatments commonly applied to conventional bedding. Available in multiple weaves (percale for crisp coolness, sateen for silky warmth), the sheets are beautifully soft, durable, and become softer with each wash. Coyuchi is a certified B Corporation committed to sustainable and ethical manufacturing, and all products are OEKO-TEX Standard 100 certified for safety.
Why This Is Great for Thyroid Patients
You spend roughly a third of your life in bed, making your sheets one of your most significant chemical exposure surfaces. Conventional cotton bedding is treated with formaldehyde-based wrinkle resistance, synthetic dyes, and flame retardants — all of which are endocrine disruptors that off-gas while you sleep. Organic cotton sheets eliminate this exposure entirely. For thyroid patients, nighttime is critical — it's when the TSH surge occurs, when immune repair happens, and when melatonin does its protective antioxidant work. Sleeping in a chemical-free bed supports these processes rather than undermining them with low-level toxin exposure.
