We roughly sleep through the third of our life - it must be important, isn't it? There is a multitude of biological processes going on, from restoring the immune system to the clearing of toxins.
Don't sleep in nylon or polyester, where the body cannot cool and it might have negative reaction to plastic. Organic and natural nightwear is what we recommend. Bamboo garments are not only very soft and pleasant but also stay cool through the night. Try it for yourself!
