This sponsor segment covers two products. Huberman explains that a 2020 Environmental Working Group study found over 200 million Americans are exposed to PFAS 'forever chemicals' via tap water, linked to hormone disruption, gut microbiome damage, and fertility issues; Rorra's countertop filtration system addresses this without installation. The ROKA segment promotes a newly co-designed red-lens glasses product, distinguishing them from traditional blue-blockers: they filter the full range of short wavelengths that suppress melatonin and raise cortisol in the evening, supporting healthy sleep onset.
