10 minutes of morning sunlight — it sets your child's circadian clock for the whole day.
Why it matters
Circadian rhythm controls hormones, appetite, mood, and learning.
Morning sunlight triggers the suprachiasmatic nucleus, resetting the entire hormonal cascade for the day
Growth hormone is released in the first 2 hours of deep sleep — disrupted rhythms stunt growth
Irregular meal times confuse insulin signaling, leading to energy crashes and poor focus
Children with consistent routines score higher on executive function tests
