誇張了點，哈哈。西方人也注意到了我提出的向著東方飛造成的時差反應問題

Jet lag is a temporary sleep disorder that can be worse when flying east than west. This is because traveling east goes against your body's circadian rhythm, or body clock, which is usually slightly longer than 24 hours. Symptoms usually appear within a day or two after crossing at least two time zones, and can last longer the farther you travel. For example, if you cross three time zones, you might be jet lagged for about three days.
