Dr. Merijn van de Laar, a sleep therapist and author of "How to Sleep Like a Caveman," explores sleep based on ancestral practices. He argues that modern sleep troubles stem from societal expectations rather than biology. Van de Laar reveals that hunter-gatherers sleep less yet remain well-rested, sharing insights on sleep cycles, light exposure, and temperature management. He challenges the eight-hour sleep myth, suggests intentional sleep deprivation for better rest, and emphasizes that a relaxed mindset can improve overall sleep quality.
