Least Toxic Yoga Mats

A reader wrote to me as a comment, asking about a yoga mat. Doing research on the response opened up the whole issue of materials used to make yoga mats. So I turned it into a post.

The issue with yoga mats is that in the past, most were made with polyvinyl chloride (PVC), which is made from and emits vinyl monomer (VCM), phthalates, and lead. Together, these materials release chemical gasses that can cause cancer, endocrine disruption, and all kinds of neurological problems.
