Sleep problems have escalated into a pervasive challenge affecting millions across the globe. In her recently released popular science book and an insightful interview with ETH News, Caroline Lustenberger, an esteemed sleep researcher at ETH, elaborates on effective strategies and pitfalls to avoid when grappling with sleepless nights.
Ask anyone, and you’ll discover that sleep disturbances are a common struggle for most. But is the prevalence of these issues truly alarming, or do we simply relish in expressing our grievances?
“If I viewed sleep issues as mere complaints, this interview wouldn’t be taking place,” Lustenberger chuckles. “It’s a significant concern, as sleep disorders are linked to profound suffering. Sleep is a fundamental human need, yet over one-third of individuals in Switzerland report experiencing moderate to severe sleep issues.”
The rise in sleep problems has been striking, especially over recent years, with self-reported sleep issues surging significantly since 2012. The Swiss government conducts extensive data collection every five years through surveys, and the latest findings indicate the highest percentages of sleep troubles recorded since the inception of these surveys in 1997. Notably, since 2017, instances of sleep difficulties have escalated, particularly among younger demographics and women.
Common sleep disorders prevalent in Switzerland encompass insomnia, sleep apnea, and restless legs syndrome. Insomnia manifests as difficulty in initiating or maintaining sleep and is frequently triggered by everyday stressors. Sleep apnea, identified by recurrent interruptions in breathing during sleep, is often related to lifestyle choices and worsened by conditions such as obesity. Restless legs syndrome, characterized by an irresistible urge to move one’s legs, deeply impacts the ability to relax and rest comfortably.
Each of these disorders necessitates tailored treatments. For individuals suffering from sleep apnea, specialized breathing machines are widely employed, alongside beneficial lifestyle modifications like weight management. Insomnia, on the other hand, often responds well to cognitive behavioral therapy, which is typically the primary treatment approach. Comfortingly, those who seek assistance frequently experience significant enhancements in their overall quality of life.
The escalating incidents of sleep disorders can be attributed to a myriad of influences. Prominent factors that have emerged in recent decades include relentless performance pressure, unclear boundaries between work and home life, and the pervasive impact of digitization. As a result, many individuals find their professional responsibilities leaking into their personal time, complicating their attempts to unwind after a taxing day.
Stress and anxiety are regarded as the foremost barriers to achieving restful sleep. Turbulent events—such as conflicts, the global pandemic, and economic uncertainties—heighten this constant state of stress.
Upon lying down, many people’s minds race, making it challenging to relax and let go of thoughts. This state of hyperarousal leaves individuals feeling perpetually tense and stressed. Additionally, the rising rates of obesity and sedentary lifestyles are further contributing to the growing prevalence of sleep disorders.
Lustenberger and her colleague Salome Kurth from the University of Freiburg have co-authored a popular guide to sleep, motivated by a dual aim of dispelling prevalent myths surrounding sleep and consolidating the latest scientific research. “We sought to demystify sleep and alleviate the excessive pressure individuals feel to achieve perfect slumber to avoid illness,” she explains. The research conducted for the book revealed a significant emphasis in the public discourse on the critical nature of sleep and the health implications of inadequate rest. While these claims hold validity over time, they also propagate immense pressure, where the fear of not sleeping ‘perfectly’ ironically exacerbates sleep issues.
In response, Lustenberger’s book presents a counter-narrative. “We illustrate the individuality of sleep experiences. Aging itself influences sleep patterns; older individuals typically experience less deep sleep and a higher frequency of awakenings during the night. Some sleep factors are outside our control—they are intrinsic to our biology.”
Lustenberger emphasizes fostering a sense of calm. “Short-term sleep issues are common and typically not a cause for concern. Our bodies exhibit an astonishing capacity for self-regulation.” The authors aim to instill acceptance in readers and encourage relaxation while also outlining actionable steps individuals can take to enhance their sleep quality.
Factors that contribute to improved sleep are multifaceted. A balanced mindset and the ability to release stress are often pivotal in overcoming milder sleep difficulties. For those facing persistent and severe challenges, seeking expert help is strongly advised.
Generally, exposure to bright light during the day and upon waking serves to reset our internal clock effectively. In contrast, incorporating dim, warm lighting in the evening while avoiding harsh screens can promote a restful environment, signaling the body to prepare for sleep.
The book delves into exciting new findings from sleep science. One significant area of discussion is the perception of personal sleep. Emerging research indicates that our outlook on sleep greatly affects our experiences of it. Moreover, the role of technology and sleep tracking comes under scrutiny; while these devices may provide some reassurance for anxious sleepers by indicating they may be getting more rest than they realize, the reliability of their data is variable.
These sleep trackers can inadvertently create more stress and obsession regarding obtaining ‘perfect’ sleep, leading to a phenomenon termed orthosomnia. Recognizing this, Lustenberger underscores the importance of approaching the outcomes from these tools with skepticism, ensuring that they do not dictate one’s self-worth or sleep quality.
Despite the advancements made, several aspects of sleep remain under-researched. Many unanswered queries linger regarding the multitude of functions sleep performs and which specific areas support particular bodily functions.
Exciting discoveries suggest that different regions of the brain undergo varying levels of sleep. Consequently, our brains do not uniformly experience sleep. Research is actively investigating why certain brain areas achieve deeper slumber than others. Each new revelation brings us closer to developing effective interventions to normalize sleep patterns and enhance long-term well-being.
When reflecting on the tips and tricks shared in her book, Lustenberger identifies her daily habits as foundational for fostering restorative sleep. “Establishing a structured routine filled with exercise, ensuring ample daylight exposure, and allowing time to unwind in the evening are essential practices.” She notes the critical role of regulating body temperature in the sleep initiation process, emphasizing the significance of warm extremities and a cool core body temperature.
In instances of worry following a poor night’s sleep, Lustenberger recommends employing mental techniques to release anxious thoughts. “I visualize placing each thought into a balloon and watching it drift away. Alternatively, jotting down concerns before bed often yields peace of mind, enabling me to postpone thinking about them until tomorrow.”
Furthermore, she advocates for focusing on gratitude by recognizing positive aspects of the day, suggesting that those struggling with sleep should redirect their mental focus towards reinforcing positive emotions. To calm turbulent thoughts, practicing simple breathing exercises might provide relief. Importantly, Lustenberger maintains trust in her body’s natural capacity to self-regulate sleep patterns; should she experience a restless night, she looks forward to a more restorative rest the subsequent evening, knowing that her sleep pressure will be heightened.
