The sleep industry is booming, driven by an increasing demand for products like advanced alarm clocks, luxury mattresses, sleep-tracking devices, and melatonin supplements. But as the market grows, so does the confusion surrounding how much sleep we actually need.
In the latest episode of the Quartz Obsession podcast, host Rocio Fabbro consults sleep expert Dr. Michael Breus, a clinical psychologist and sleep specialist, to unpack the complexities of achieving restful sleep. The discussion covers the expansive market for sleep aids, whether these products truly help, the biological necessity of sleep, and the mental and physical changes that happen while we dream.
Dr. Breus sheds light on the evolution of insomnia, attributing its rise partially to societal changes initiated during the industrial revolution. He notes that technological innovations like the light bulb and changes in work patterns, such as overtime compensation, profoundly altered sleep quality and habits. Stress, particularly in today’s fast-paced world, is highlighted as a primary factor affecting sleep disorders, with lifestyle changes contributing to increasing insomnia cases.
The episode also delves into the influence of screen time on sleep quality. Dr. Breus explains the effects of engaging with smartphones in bed, emphasizing the impact of mental stimulation and the need to establish a “runway” to facilitate better sleep.
Dr. Breus shares his unique background, combining psychology and sleep medicine, which helps him approach insomnia holistically. He stresses the importance of addressing both the psychological and physiological aspects of sleep, offering a range of practical strategies to improve sleep quality, such as maintaining a consistent wake-up time, regulating caffeine and alcohol intake, and ensuring regular exercise.
Additionally, listeners discover that misconceptions about sleep, like the belief that everyone needs eight hours, can hinder their understanding of their personal sleep needs. The podcast encourages individuals to be proactive in seeking what their bodies require for optimal rest, while also tackling myths that contribute to sleep anxiety.
As the conversation progresses, Dr. Breus shares insights from his research on chronotypes—genetic predispositions that influence sleep preferences—and how understanding one’s chronotype can guide better sleep practices.
Ultimately, this episode emphasizes the significance of personal responsibility in managing one’s sleep health, underscoring that while advancements in sleep medicine are promising, individual discipline is key to achieving lasting improvements in sleep quality.
