Matt and Dr. Eti Ben Simon return with another AMA episode where they answer such listener questions as how sleep loss amplifies tinnitus and how Seasonal Affective Disorder impacts circadian rhythm. They also reveal that sleep restriction slashes vaccine-induced antibody production by 50%, and highlight deep NREM sleep as the vital soil for immunological memory.

The hosts go on to analyze somniloquy, address long COVID’s inflammatory sleep fragmentation, and critique the fading efficacy of CBD/CBN. They also blueprint an optimal bedroom, and ultimately, emphasize that consistent regularity remains the primary architect of biological restoration.
