Can you really catch up on lost sleep? Does melatonin actually help you sleep better? And is morning sunlight as important as everyone says? In this episode of The Dr. Plant Podcast, Dr. Joshua Plant sits down with sleep and circadian rhythm researcher Dr. Steve Lockley to challenge common beliefs about sleep and uncover what the science actually shows. They explore how sleep deprivation affects metabolism, immunity, cognition, and long-term health, why your internal clock matters, and how light, caffeine, exercise, and daily routines influence sleep quality. Dr. Lockley also breaks down the research behind popular sleep supplements, including magnesium and melatonin, and shares practical strategies for getting better rest. If you've ever wondered whether you're really getting the sleep your body needs, this conversation might change the way you think about your nights. Sponsored by The Science Standard.
