Yoga (and several other exercises) is done on a mat, and because you sweat and also keep the mat on the floor, its important to understand the proper cleaning and maintenance of your mat.
When you visit a yoga studio, it is a must to provide your own yoga mat. A vast majority of dermatologists state that they have seen significant infections, rising from people who practice yoga while using public mats. In order to avoid contracting plantar warts or something more serious such as a staph infection, make sure to purchase a good quality yoga mat.
Yoga poses need regular practice. Therefore a quality mat that has a long lasting life is preferred. An inferior mat will wear out within a year. Pick a good mat with a high density, rather than buying a mat that feels “cushy and soft on the knees.”
Check your mat when you open it up for the first time. Look to see if there is a thin slippery film on it. Even a high quality mat like the Manduka black mat, may have a bit of film when first used.
You will need to clean this off before the first use, otherwise you may lose grip and possibly slide on the mat.
