Researchers warn that healthy sleep depends on more than personal habits.
BRUSSELS
Rising nighttime temperatures, demanding work schedules and the growing obsession with tracking sleep are creating new challenges for Europeans seeking adequate rest. Researchers are warning that poor sleep cannot be addressed through individual lifestyle changes alone, calling for coordinated public policies that recognize its environmental, technological and socioeconomic dimensions.
A paper published in the Journal of Sleep Research identifies five major areas of concern: climate change and urban environments, unequal access to sleep healthcare, digital health technologies, online misinformation and an increasingly connected work culture.
Fran Pilkington-Cheney, a sleep researcher at Nottingham Trent University and co-lead author, argues that these pressures interact in ways that make healthy sleep harder to achieve.
Climate change is becoming particularly important. Hotter nights can interfere with the body’s natural cooling process, delaying sleep and increasing nighttime awakenings. The problem is especially relevant in Europe, where temperatures are rising rapidly.
Previous research published in One Earth analyzed more than seven million sleep records from approximately 47,600 people across 68 countries. It found that unusually warm nights were associated with shorter sleep duration, with particularly pronounced effects among older adults, women and people living in lower-income countries.
Environmental inequality compounds the problem. Residents of poorly insulated homes, overcrowded housing or neighborhoods affected by noise and artificial lighting may have fewer opportunities to maintain comfortable sleeping conditions.
Technology introduces a different contradiction. Smartwatches and sleep-monitoring applications can help users identify patterns, but their measurements are not necessarily reliable enough to diagnose medical conditions.
Researchers have also highlighted orthosomnia, a term describing excessive concern about achieving ideal sleep measurements. Constantly monitoring sleep scores may generate anxiety rather than improve rest.
This concern intersects with sleepmaxxing, a social media trend that promotes elaborate routines, specialized products and methods intended to optimize sleep.
Some recommendations associated with the trend overlap with established sleep-health practices. Others lack convincing scientific evidence, making it important to distinguish clinical guidance from commercial promotion.
Workplace conditions represent another structural obstacle. The researchers cite estimates indicating that approximately 21% of European workers participate in shift work, potentially disrupting the body’s natural sleep-wake cycle.
Healthcare employees, transport workers and others with irregular schedules may experience particular difficulties. After-hours messages and expectations of constant availability can further reduce opportunities for recovery.
The study’s authors advocate policies involving predictable working hours, improved access to sleep medicine, better urban planning and stronger standards for digital health information.
Their recommendations do not imply that personal habits are irrelevant. Consistent sleep schedules and appropriate sleeping environments remain useful, but individual behavior cannot fully compensate for excessive nighttime heat, insecure employment or limited healthcare access.
The wider implication concerns how governments define public health. Sleep is often treated as a private responsibility, even though the conditions supporting it are shaped by housing, infrastructure and labor arrangements.
Europe’s emerging sleep challenge may therefore require changes extending far beyond the bedroom.
