Recommended Sleep Duration for Three-Year-Old Children
Sleep Duration Guidelines for Preschoolers
- The World Health Organization (WHO) and Canadian Guidelines recommend that children aged 3-4 years should have 10-13 hours of quality sleep in a 24-hour period, which includes both nighttime sleep and daytime naps 1, 2
- Regular sleep patterns with consistent bedtime and wake-up times are essential components of healthy sleep habits for three-year-olds 2
Benefits of Adequate Sleep for Three-Year-Olds
- Sufficient sleep duration in early childhood is associated with improved health outcomes, including lower energy intake and reduced risk of obesity 1
- The risk of overweight/obesity is significantly increased when short sleep duration is coupled with a late bedtime 1
Consequences of Insufficient Sleep
- Sleeping less than the recommended amount has been linked to lower quality-of-life later in childhood 1
- Increased risk of excessive weight gain is associated with sleeping less than the recommended amount 2
Sleep Timing Considerations
- Later sleep onset and later sleep midpoint have been associated with higher nighttime energy intake 1
- Later sleep onset and later sleep midpoint have been associated with lower morning energy intake 1
- Later sleep onset and later sleep midpoint have been associated with delayed timing of both first and last meals of the day 2
- Later sleep onset and later sleep midpoint have been associated with greater adiposity gain in follow-up studies 2
