Sleep Habits

Sleep/wake schedule

The UK population goes to sleep around 11:15PM and wakes up around 7:00 AM. The population sleeps on average 6 hours 50 minutes. On week ends or days off, they sleep about 68 minutes more than on week days. The bedtime and wake up times are varying for more than one on five individuals.

Naps

About one on seven individuals are regularly napping. 1% of the population is napping at least two times in the same day.

Insomnia

  • One on eight individuals has difficulty falling asleep
  • One on five individuals has a disrupted sleep
  • One on seven individuals wake up too early in the morning
  • One on six 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.
