Children's Sleep Cycles
Unlike adults, children complete one sleep cycle approximately every 60 minutes. Each cycle consists of 5 stages.
Sleep Stages
Stages 1-2 (Light Sleep)
The beginning of sleep. Children can easily wake to small noises.
Stages 3-4 (Deep Sleep)
Deep, restful sleep. Breathing slows and the body completely relaxes.
Stage 5 (REM Sleep)
The brain becomes active and dreams occur. This is when eyes move rapidly.
Differences by Age
- • 3-year-old: 33% of sleep is light sleep
- • 13-year-old: Only 20% of sleep is light sleep
As children age, deep sleep increases, making them less likely to wake to small noises.
Why Is Kids Sleep Calculation Important?
Adequate sleep is essential for a child's growth and development.
Physical Growth
Growth hormones are primarily secreted during deep sleep.
Brain Development
Sleep helps improve memory, attention, and learning abilities.
Emotional Development
Adequate sleep is important for emotional regulation and behavioral development.
Immune System Boost
The immune system strengthens during sleep, increasing resistance to illness.
