The amazing nature of breast milk, and why it might even help with the battle to sleep through the night! –
Breast milk changes dramatically over the course of the day. For example, levels of cortisol – a hormone that promotes alertness – are three times higher in morning milk than in evening milk.
Melatonin, which promotes sleep and digestion, can barely be detected in daytime milk, but rises in the evening and peaks around midnight.
Night milk also contains higher levels of certain DNA building blocks which help promote healthy sleep. Day milk, by contrast, has more activity-promoting amino acids than night milk.Iron in milk peaks at around noon; vitamin E peaks in the evening. Minerals like magnesium, zinc, potassium and sodium are all highest in the morning.
Daytime milk may pack a special immune punch. Among mothers who provided researchers with milk samples across the first month postpartum, immune components – including key antibodies and white blood cells – looked higher in day milk compared to night milk.
Another study found higher levels of a component important for immune system communication in day milk compared to night milk.While it’s clear that milk changes over the course of the day, scientists know little about what this means for infant health.
