Sleep Habits

Sleep/wake schedule

The German population goes to sleep around 10:50PM and wakes up around 6:20 AM. They sleep on average 7 hours 8 minutes. On week ends or days off, they sleep about 85 minutes more than on week days. The bedtime is varying for more than one on three individuals while the wake up time is varying for one on six individuals

Naps

About one on five individuals are regularly napping. Nearly 4% of the population is napping at least two times in the same day.

Insomnia

  • One on six individuals has difficulty falling asleep
  • One on four individuals has a disrupted sleep
  • One on seven individuals wake up too early in the morning
  • One on seven individuals feels sleep is not refreshing

One individual on ten complained about the quality or quantity of his or her sleep. This does not mean that all these individuals are insomniacs: only one on 16 individuals has a diagnosis of insomnia.
