Question

why we feel sleepy after 1:00 to 2:00 a.m ?​

Answer 1

Answer:

Post-lunch sleepiness can stem from a dip in your core body temperature that naturally happens between 2:00pm and 4:00pm. It's a dip that triggers the release of a snooze-inducing hormone called melatonin. It's a normal part of your body's circadian rhythm.

It is our body clock. Our body clock feels us when we are hungry, sleepy etc. It is not compulsory that everyone gets sleepy at one or two a.m. Everyone has different body clock alarm.
