While milk has been associated with sleep for a long time, the evidence is mixed. It's often thought that the warmth and familiar taste of milk, particularly warm milk, can be soothing and promote relaxation, which might help with sleep.
Milk contains the amino acid tryptophan, which plays a role in producing serotonin and melatonin, hormones associated with sleep regulation. However, the amount of tryptophan in milk is relatively low, and it's unlikely to have a significant impact on sleep.
Some studies suggest that consuming milk and other dairy products can be part of a healthy diet that supports good sleep quality. However, there is no definitive scientific evidence that milk itself directly makes you sleepy.
In conclusion, while drinking warm milk before bed might offer a comforting ritual and contribute to a relaxing bedtime routine, it's unlikely to have a significant direct effect on sleep quality.
