It often takes a few days for your biological clock to align with a new time zone. Adjusting after “gaining” time may be slightly easier than after “losing” time because the brain adjusts differently in the two situations.
What is light dark cycle?
The light-dark cycle is the major synchronizer of human circadian rhythms. Without this time cue, many blind persons, especially those with no light perception at all, cannot remain on a 24-hour circadian clock.
Can you have a negative pregnancy test and no period?
