Sleep Disorders Cost Germany €106 Billion Annually; Time Change Impacts Pain Sensitivity, While Spring Fatigue is Debunked
Nearly one in three Europeans experiences sleep disturbances, with significant health and economic consequences. New data released on World Sleep Day highlights the scale of the problem, while simultaneously debunking the widely held belief in “spring fatigue.”
The Underestimated Economic Impact of Sleep Loss
The financial toll of inadequate sleep is substantial. A recent analysis by the German Society for Neurology (DGN) reveals that the five most common sleep disorders – obstructive sleep apnea, chronic insomnia, restless legs syndrome, narcolepsy, and REM sleep behavior disorder – cost Germany approximately €106 billion annually.

These costs encompass both direct medical expenses and indirect losses stemming from reduced work productivity. The most prevalent issues are sleep apnea (affecting 18 percent of the population) and chronic insomnia (10 percent). While less common, restless legs syndrome and narcolepsy also contribute significantly to the overall burden.
“Early diagnosis is crucial,” emphasizes Dr. Michael Westhoff, a specialist at the Hemer Lung Clinic’s sleep medicine center. Tagesspiegel. Prompt identification and treatment can prevent secondary health problems and sustainably improve the quality of life for those affected.
Time Change and Pain Sensitivity
The German Society for Pain Medicine (DGS) cautions about the upcoming daylight saving time change at the complete of March. Losing even one hour of sleep can disrupt the body’s internal clock, creating a “mini jet lag” effect that lasts up to 14 days.
Alarmingly, insufficient sleep – less than six hours – can increase pain sensitivity by as much as 32 percent. This is because the brain utilizes the glymphatic system during deep sleep to eliminate toxins that contribute to inflammation. Experts recommend gradually adjusting bedtime in the days leading up to the time change to mitigate these effects.
Debunking the Myth of Spring Fatigue
Despite widespread belief, chronobiologists in Basel have found no biological basis for “spring fatigue.” A year-long study involving 418 participants revealed no objective evidence of a seasonal dip in energy levels. Researchers conclude that the feeling of exhaustion in spring is more likely a cultural expectation than a genuine physiological syndrome.
Sleep Hygiene: An Increasingly Crucial Economic Factor
The latest data underscores the vital link between sleep, health, and productivity. World Sleep Day’s motto, “Sleep Well, Live Better,” emphasizes the importance of practices like reducing blue light exposure in the evening, maintaining consistent bedtimes, and creating a quiet sleep environment.
Given that sleep deprivation impairs cognitive function and increases the risk of accidents, employers are increasingly recognizing the need to prioritize sleep health. The substantial financial losses resulting from reduced work hours are likely to drive further investment in employee education programs in the coming months. Well-rested employees are demonstrably healthier and more productive.
On March 13, 2026, Beate Klofat, a psychotherapist and clinical psychologist in Bavaria, participated in World Sleep Day activities by conducting a video interview with a local newspaper, emphasizing the benefits of good sleep and the need for greater societal awareness of sleep health.
