What's the deal with red light therapy?

About this episode

Emily and Perry discuss red light therapy and its various claims, along with other health topics including polio and multivitamins.

This week, Emily and Perry shine a light on red light therapy: its origins, its heroic use of the mighty mitochondria, and the supposed countless benefits (better mood, wound healing, facial rejuvenation, hair regrowth?) of sitting in front of a hot red light that may or may not even be able to penetrate your skin. Plus: the disturbing return of polio, whether multivitamins have an effect on epigenetic aging, and if the pitch clock, while modestly good for Emily's enjoyment of baseball, is ruining pitchers' elbows.
