In today’s world, there is a booming market focused on improving sleep, with products ranging from high-tech gadgets and luxurious mattresses to sleep trackers and melatonin supplements. But the essential question arises: Is it worth investing so much in the quest for better sleep?
In the final episode of season 8 of the Quartz Obsession podcast, sleep expert Dr. Michael Breus lends his insights on various aspects of sleep that often keep people up at night. He discusses the growing sleep industry, the reasons behind our need for sleep, and what occurs in our bodies during the dreaming phase.
Dr. Breus, a double board-certified clinical psychologist and sleep specialist, reveals that the understanding of insomnia has drastically evolved over time. Historically, before technological advancements such as the light bulb and the cultural shift toward longer working hours, sleep disorders were hardly recognized. He emphasizes that modern society is facing unprecedented stress levels, which he estimates accounts for about 75% of insomnia cases. Factors like increased screen time, lifestyle changes, and medications also contribute to sleep disturbances.
The discussion delves into the impacts of nighttime habits like scrolling social media on sleep quality. According to Dr. Breus, while the light from screens may not be as harmful as commonly thought, the engagement from notifications and social media can hinder the winding down process needed before sleep.
Listeners are encouraged to consider their own sleep patterns, especially in relation to chronotypes, which refer to the natural preference for sleep times. Dr. Breus explains that understanding one’s chronotype can inform better sleep habits and timing for activities throughout the day.
The podcast further explores historical sleeping patterns, noting how in medieval times, it was common for people to have a biphasic sleep schedule, waking up in the middle of the night to work or socialize. Dr. Breus points out that while modern lifestyles tend to favor a single block of sleep, some individuals still experience natural awakenings during the night, which can be addressed with practical techniques.
Listeners eager for practical advice are presented with a five-step plan to enhance sleep quality, including maintaining a consistent wake-up time, avoiding caffeine and alcohol before bed, and incorporating daily exercise. The advice is designed to help individuals reset their circadian rhythms and promote restorative sleep.
As advancements in sleep medicine continue, Dr. Breus anticipates developments in both pharmaceutical treatments and cognitive behavioral therapy approaches, including AI tools that may assist individuals in managing their sleep better. He urges that success in achieving good sleep not only relies on medications but, more importantly, on individuals taking responsibility for their sleep hygiene.
Ultimately, the discussion serves as an enlightening resource for listeners looking to improve their sleep quality, illustrating the intricate relationship between sleep and overall health.
