Night Milk: Natural Sleep Aid or Scientific Curiosity?
Night milk might help you sleep a little better because it has more sleepy hormones than milk collected during the day.
But scientists aren't sure if it works well in people yet.
It's like a natural, gentle sleep aid, not a strong medicine.
Night milk contains higher levels of melatonin and serotonin-related compounds
Animal studies show mice slept faster and longer after consuming night milk
Human studies are limited, but suggest mild sleep benefits
Factors like lighting, cow breed, and season affect melatonin content in milk
Night milk is safe but not a strong sleep medicine or insomnia treatment

Practicality
Proponents of night milk
Night milk could be a natural, gentle sleep aid

- Melatonin in night milk
- Up to 5 times higher than in daytime milk
- Serotonin in night milk
- Also higher, which converts to melatonin
- Human studies
- Limited and small, no large-scale clinical trials yet
- Animal studies
- Show mice slept faster and longer after consuming night milk
- Factors affecting melatonin content
- Lighting, cow breed, season, stress, etc.
