It is a common question as to what is the optimum sleep duration?
- The two most common sleep disturbances are insomnia, likely present in 5-15% of the population, and obstructive sleep apnea (OSA), estimated in 10% of men and 3% of women <50 years of age.
- Based on both short sleep duration (<7 hours per night) and long sleep duration (>9 hours per night) disorders as well as OSA and insomnia are associated with poor health risk and outcomes.
- In general, compared to patients with normal sleep duration, sleep restriction studies report increased caloric intake.
- Sleep behaviour deserves attention
