In the bustling sleep industry, which encompasses everything from high-tech sleep gadgets to melatonin delivery services, a growing question arises: should investors be betting on this sector in the hopes of improving sleep quality?
In the latest episode of Quartz Obsession, host Rocio Fabbro interviews Dr. Michael Breus, a distinguished clinical psychologist and sleep specialist. During their discussion, they delve into several pressing questions about sleep that keep many up at night. Why has the market for sleep-related products thrived? Do any of these products genuinely aid in achieving quality rest? What physiological processes occur while we sleep, and why is it essential for us to do so?
Dr. Breus emphasizes that the landscape of insomnia has evolved significantly. Historically, insomnia wasn’t widely recognized before innovations like the light bulb extended working hours, altering our natural sleep patterns. Today, he argues that stress is the predominant factor disrupting sleep for many, citing that three-quarters of insomnia cases stem from stress and some form of depression. Environmental influences, such as increased screen time and alcohol consumption, contribute to a declining sleep quality.
In the conversation, Breus addresses the commonly held belief that one should keep their phone near while trying to sleep. He labels this a “cardinal sin,” explaining that while some light exposure from devices might not have a major impact, the engagement from using these devices—whether gaming or scrolling through social media—keeps the brain active and alert, contrary to the relaxation needed for sleep.
Rocio and Dr. Breus also explore various cultural approaches to sleep, highlighting how historical practices have led to contemporary misunderstandings about sleep requirements. For instance, the notion that everyone needs eight hours of sleep is a misconception; instead, Breus encourages individuals to focus on how they feel after waking up rather than a specific number of hours.
The episode wraps up with Dr. Breus offering practical tips for enhancing sleep quality. His five-step plan includes maintaining a consistent wake-up time, restricting caffeine intake by 2 PM, minimizing alcohol consumption before bed, engaging in regular exercise, and implementing a morning routine that helps adjust the body’s natural rhythms.
As the conversation unfolds, listeners gain insights into the complexities of sleep and how advancements in both pharmaceuticals and therapies—like cognitive behavioral therapy for insomnia—can help improve sleep health. Dr. Breus also highlights the potential of upcoming innovations, including AI-driven sleep studies and improved sleep technology, paving the way for more effective and personalized sleep solutions.
