What are the benefits of drinking milk at night?

Milk, along with other dairy products, emerges as a commendable source of tryptophan, an amino acid renowned for its sleep-promoting attributes. Tryptophan serves as a precursor for the synthesis of both melatonin and serotonin within the body. Melatonin, often referred to as the ‘sleep hormone,’ ensures that the sleep-wake cycle is in check, ensuring a harmonious transition into a restful sleep. Serotonin, on the other hand, functions as a multi-faceted neurotransmitter, contributing not only to mood regulation but also playing a pivotal role in appetite control, sleep modulation, and pain perception. This symphony of molecules collaborates to induce a sense of tranquillity, gently guiding you toward a peaceful night’s rest, explains Sharma.

While sipping warm milk may help you sleep better, it may not be suitable for everyone out there. Factors such as personal tolerance, dietary preferences, and overall health should all be taken into account when considering the timing and quantity of milk consumption before sleep, adds the expert.
