Journal Club with Dr. Peter Attia | Effects of Light & Dark on Mental Health & Treatments for Cancer

In this journal club episode, my guest is Dr. Peter Attia, M.D., a Stanford and Johns Hopkins-trained physician focusing on healthspan and lifespan and the host of The Drive podcast. We each present a peer-reviewed scientific paper chosen because it contains novel, interesting, and actionable data. First, we discuss a paper on how bright light exposure at sunrise and throughout the day and dark exposure at night independently improve mental health and can offset some of the major symptoms of mental health disorders such as depression and anxiety. Then, we discuss an article that explores a novel class of immunotherapy treatments to combat cancer. We also discuss some of the new data on low-calorie sweeteners and if they are safe. This episode should be of interest to listeners curious about maximizing their vitality and longevity and to anyone seeking science-supported ways to improve mental health and lifespan.

EPISODE SUMMARY

In this episode of Huberman Lab, featuring Andrew Huberman and Peter Attia, Journal Club with Dr. Peter Attia | Effects of Light & Dark on Mental Health & Treatments for Cancer explores light, Darkness, and Immunity: Rethinking Mood Disorders and Cancer Therapies Andrew Huberman and Peter Attia co‑host a journal club focused on two major themes: how light and dark exposure shape mental health, and how modern immunotherapies are changing cancer treatment. Huberman reviews a large UK Biobank study (~86,000 people) showing that bright daytime light and dark nights independently and additively reduce risk and severity of multiple psychiatric disorders. He explains the underlying circadian and retinal mechanisms, and translates them into concrete daily light/dark practices.
