Does warm lactose free milk make you sleep?

Warm lactose-free milk can promote sleep due to its high tryptophan content, an amino acid that helps produce serotonin and melatonin, hormones involved in regulating sleep. The warmth of the milk may also have a calming effect, making it easier to relax before bedtime. However, individual responses can vary, and while it may help some people, others might not experience a noticeable effect.
