Sunlight or fake light? We explore how light timing and intensity shape the circadian clock, mood, hormones, fertility, and sleep—and why amplitude is the missing key. Sean Kane shares new research on individual light sensitivity, depression and bipolar patterns, and practical fixes that work.
Sean Cain, PhD is a Matthew Flinders professor of circadian biology at Flinders University, Australia. He has more than 25 year of research into human circadian system and how light affects health.
