The sleep industry is thriving, with a plethora of products designed to help people improve their sleep, including sophisticated alarm clocks, high-end mattresses, wearable devices that track sleep cycles, and subscriptions for melatonin. However, the question remains: is it wise to invest so heavily in the pursuit of better sleep?
In the latest episode of the Quartz Obsession podcast, host Rocio Fabbro speaks with Dr. Michael Breus, a clinical psychologist and sleep expert, to discuss the complexities surrounding sleep and the growing insomnia epidemic affecting many people today. Dr. Breus provides insights into several crucial questions: Why is there such a robust market for sleep products? Do any of these items genuinely help improve sleep quality? What biological necessity drives our need for sleep, and what happens to our brains and bodies while we dream?
Dr. Breus notes that insomnia has evolved over time, largely influenced by modern technological advances, such as the invention of the light bulb by Thomas Edison and the rise of the industrial revolution, which led to shift work. He explains that stress is one of the primary contributing factors to insomnia today, affecting approximately 75% of those who struggle to sleep. The doctor also emphasizes the impact of environmental stressors, such as increased screen time and substance use, on sleep quality.
Listeners learn that the proximity of devices like smartphones is detrimental to sleep, as engaging with them when struggling to fall asleep can further stimulate the brain instead of calming it. Dr. Breus distinguishes between passive content consumption on television, which he considers acceptable as it allows for mental relaxation, and active engagement via smartphones, which often leads to heightened alertness.
The episode touches on the importance of understanding one’s natural sleep patterns, or chronotypes, and adapting sleep schedules accordingly. Dr. Breus explains how historical sleep practices, such as biphasic sleep common in agrarian societies, have changed with industrial advancements. He provides practical strategies that can improve sleep hygiene, including maintaining consistent wake-up times, limiting caffeine and alcohol intake, and engaging in regular physical activity.
Dr. Breus warns against misconceptions about sleep, such as the belief that everyone requires eight hours or that tossing and turning in bed is a natural part of the sleep process. He advocates for a tailored approach to sleep based on individual needs, which includes potentially seeking cognitive behavioral therapy for insomnia as an alternative or complement to medication.
Looking ahead, Dr. Breus discusses promising advancements in sleep science, including genetic research that may lead to more tailored treatments for insomnia and innovations like wearable technology designed to enhance relaxation and optimize the body’s natural rhythms.
For those seeking to improve their sleep, Dr. Breus encourages listeners to adopt a disciplined approach by implementing simple strategies that can yield significant improvements in sleep quality and overall health.
