Milk has long been associated with promoting sleep, and there's some scientific evidence to back this up. Milk contains tryptophan, an amino acid that helps the body produce serotonin and melatonin. Serotonin is a mood-regulating neurotransmitter, while melatonin is a hormone that plays a crucial role in regulating sleep cycles.
However, the effect of milk on sleep is not solely due to tryptophan. Warm milk may also have a calming effect due to its association with bedtime routines and a sense of comfort. The warmth itself could also contribute to relaxation, promoting sleepiness.
While milk may not be a miracle sleep solution, it can be a part of a healthy sleep routine. Incorporating a glass of warm milk before bed can contribute to a sense of calm and relaxation, potentially helping you drift off to sleep easier.
