What Effect Does Light Have on My Newborn's Sleep?
How does light affect your newborn's sleep? Light, especially sunlight, blue or white light cause the brain to produce Serotonin. The Serotonin hormone is converted to Melatonin when it's dark. Melatonin makes us drowsy but it is inhibited by light. This is why as adults we find it difficult to fall asleep after using our mobile devices at bed time. Build up plenty of stores of Serotonin in their system during the day with time outdoors and they'll be set for a nice, snoozy evening.
