The sleep industry is booming, driven by high-tech gadgets, luxury mattresses, sleep trackers, and melatonin products. But is investing in these items genuinely beneficial for improving sleep quality?
In the final episode of season 8 of the Quartz Obsession podcast, host Rocio Fabbro speaks with renowned sleep expert Dr. Michael Breus. Together, they discuss several pressing questions regarding sleep, including the expansive market for sleep-related products, the effectiveness of these items, the fundamental need for sleep, and the biological processes occurring during sleep.
Dr. Breus, a double board-certified clinical psychologist and sleep specialist, provides insights into the complexities of insomnia, its evolution over time, and its relationship with modern stressors. He notes that insomnia has changed dramatically since the days when pre-industrial societies faced fewer sleep disorders. The invention of the light bulb, introduction of overtime work, and the societal shift towards longer work hours have all contributed to increased sleep-related issues.
The conversation highlights how stress, screen time, and other environmental factors have adversely affected sleep quality. Breus emphasizes that most insomnia cases stem from stress or depression, exacerbated by lifestyle choices, including increased alcohol consumption and late-night screen use.
Fabbro shares her own struggles with sleep, particularly her habit of scrolling through social media at night, which Dr. Breus warns against due to its disruptive nature. He argues that while light exposure from devices has some impact, the engagement with such platforms is more concerning. Instead, he suggests creating a calming bedtime environment that allows for a smoother transition to sleep.
Breus explains his unique perspective as a sleep expert with a clinical psychology background, highlighting the interplay between mental health and sleep quality. He underscores the significance of tailored treatments that consider both psychological and physiological factors affecting insomnia.
They also discuss the historical and cultural perspectives on sleep, such as the concept of biphasic sleep typical in agrarian societies, where individuals would wake in the middle of the night for various activities. Breus explains that modern biological processes still reflect this pattern; many people naturally experience brief awakenings during the night.
The episode concludes with Breus offering practical advice on improving sleep without relying solely on medication. His five-step plan includes maintaining a consistent wake-up time, moderating caffeine and alcohol intake, engaging in regular exercise, and other strategies aimed at enhancing sleep hygiene.
As research into sleep continues to evolve, Breus anticipates the development of new treatments that could better address individual sleep needs, including the integration of AI in sleep medicine.
The podcast episode serves as a valuable resource for those looking to understand the dynamics of sleep and find innovative ways to improve their sleep quality.
