Around four p.m.
Around four o'clock in the afternoon is also the best time to drink milk.
An hour before going to bed
Drinking milk an hour before going to bed at night may help you sleep, and you can lock the nutrition of milk as much as possible so as not to lose it.
Avoid boiling
If you have the habit of drinking hot milk, you must avoid boiling milk, because it will cause evaporation of nutrients.
