For some odd reason it NEVER affects me in terms of my sleeping timetable or any tiredness. When I go to Pak, I land during the morning and I’ll be active like normal all day and sleep at night like normally.
When I came to Pakistan, I mean arrived in Lahore, I slept the whole day the next day. When I woke up had weird headaches. Adjusted after 2 days. Oddly enough, whenever I go back to Dubai, I don't feel jet lag at all but I am super excited :/
jet lag occurs when you go across multiple time zones and accumulates significant amount of time difference b/w your starting point and final destination in a short interval of actual passage of time. Hence your body continues to operate in a “time lag” till it catches up with your current geographical presence.
