Question

why we are sleeping in travel

Answer 1

Answer:

We gets cool air while travelling and we fall asleep

Answer 2

When traveling to a new time zone, our circadian rhythms are slow to adjust and remain on their original biological schedule for several days. This results in our bodies telling us it is time to sleep, when it's actually the middle of the afternoon, or it makes us want to stay awake when it is late at night.
