You may not be able to see it, but your sheets absorb a lot of perspiration and skin and hair oils. Regular washing is enough to remove any unseen bacteria, but if your allergies are severe, or if you don’t have time to wash your bedding as often as you’d like, consider investing in bamboo sheets. Bamboo has naturally occurring antimicrobial and antifungal properties, and also wicks away moisture. This means bacteria can’t survive on the fabric for very long, and it is harder for mildew to grow. For more information about bamboo fabric, see our “Sustainable Fashion” section.
