The sleep industry is thriving, with many products ranging from sunrise alarm clocks to high-end mattresses and sleep trackers. But is our financial investment in sleep solutions justified? As insomnia rates climb, understanding the science of sleep has become increasingly important.
In the latest episode of the Quartz Obsession podcast, host Rocio Fabbro speaks with Dr. Michael Breus, a dual board-certified Clinical Psychologist and Clinical Sleep Specialist. Together, they explore the burgeoning sleep market and address several pressing questions.
Why is there such a high demand for sleep-related products? Are they effective? What role does sleep play in our overall health? And what actually occurs in our bodies while we dream?
Dr. Breus highlights how society’s relationship with sleep has changed over time. The introduction of electricity and the demand for longer work hours have thrust many into sleep disorders that were previously uncommon. He attributes a significant portion of insomnia—about 75%—to stress and mental health issues, with the remaining percentage linked to environmental factors and medical conditions that disrupt sleep patterns.
The conversation also touches on the common habit of using smartphones late at night. Dr. Breus cautions against this, advocating for a more peaceful bedtime routine away from screens. He discusses the importance of allowing the brain to unwind before sleep, contrasting the effects of passive television viewing with engaging activities on smartphones.
For those struggling with sleep, Dr. Breus emphasizes the importance of understanding one’s own sleep patterns and genetic predispositions. He discusses the concept of chronotypes—distinct sleep preferences that can affect how and when people sleep. He explains that people can optimize their sleep by aligning their sleep schedule with their natural body rhythms.
Additionally, the podcast addresses the historical context of sleep habits, noting how past societies engaged in biphasic sleep—an arrangement where people would wake up in the middle of the night for various activities. Modern life, with its reliance on clock time and artificial light, has complicated these natural cycles.
The conversation also digs into potential future advancements in sleep medicine, from new treatments for insomnia to technological innovations that could track and improve sleep quality. Dr. Breus suggests that a return to understanding and working with the body’s natural rhythms, along with emerging therapies, can lead to better sleep for all.
For those seeking immediate solutions, Dr. Breus provides actionable advice, including consistent wake-up times, limiting caffeine and alcohol intake, and engaging in daily exercise, emphasizing the importance of quality over quantity in sleep.
The episode serves as a thorough exploration of sleep from both a personal and cultural perspective, offering valuable insights for anyone looking to improve their rest.
