Crossing time zones decouples our biological rhythms from the natural cycle of light and dark we're used to. We perceive light cues through retinal photoreceptors that relay signals to the suprachiasmatic nucleus (SCN) in the brain. "Phase adjustments" in peripheral tissues ensure that each clock follows the same schedule. These can be set indirectly through SCN-dependent biological rhythms, such as feeding cycles or body temperature. How synchronizing cues operate at the molecular level, however, remains obscure...

It's a physiological condition which is a consequence of alterations to the circadian rhythm - when traveling across a number of time zones, the body clock goes out of sync with the destination time, and so it experiences daylight and darkness contrary to the rhythms to which it has grown accustomed. The body's natural pattern therefore becomes upset as the rhythms that dictate times for eating and sleeping no longer correspond to the environment of the destination.
Jet lag occurs because the body cannot automatically realign these rhythms. The speed at which the body readjusts itself to new daylight, darkness hours, and eating and sleeping patterns is entirely dependent upon the individual. Thus, while it may take a few days for some people to readjust to a new time zone, others seem to experience little disruption to their body's natural sleeping pattern.

Actually, the only reason this would affect your body is because different time zones will see the sun at a different position. So yes, it most definately affects you, but it doesn't affect you drastically from zone to zone- you have to go several zones away before your body REALLY needs to adapt. Though if you don't traverse time zones very far, it will affect you considerably, if only because your favorite show is on at a different time than the one you're used to! Even this will affect the body in the most miniscule way, because, without experience in the matter, your body is confused. It takes several times of traversing to a different time zones to get your body used to it, and you need to do it every several months to maintain the body's response to it. For example, my grandmother lives in Dickinson, ND, in the mountain time zone, while I live in Sioux Falls, in the central time zone. I travel there every two-three years, but my body is not used to it, so it gets disoriented when it fails to recognize that my position on the Earth has changed (your internal organs need to have the time to adjust to this, since the rest of your body cannot simply get a message from your brain that it is at a different place on the earth, and since the daily rhythms are out of tune, your body simply cannot instantly adapt to the psychology created by the sun rising and setting at different times). This is also true at night, as long as a person's body is not used to the current position of our sole celistial body, the moon. Even the position of the stars are said to have a direct effect on our system! And yes, I could give you a shorter answer, but it wouldn't have been as easy to understand!

You really mean "crossing" the the time zones, right?
Well if you cross only one or two time zones maybe you would feel nothing. But if you travel almost half the globe then your sleeping pattern is affected! You will get at least a little headache - the sickness is called jet lag.

Certainly it should affect a normal human being of normal sleep-wakeup routine and the ability to perform physical tasks and energy spent.
It is a medical phenomenon, that our body requires certain amount of light exposure and some amount of sleep rest to keep itself fit. Medical scientists are advising people to expose their bodies to natural light for better health than spending inside closed doors in offices with lamps on. If such a small thing for a prolonged time can affect the physiological clock cycles, it is certain that time zone changes affects our clock cycles and thereby routine life pattern.

No, it doesn't really affect your body directly. If time zones weren't invented, then this question couldn't even be asked. Time zones are a man-made concept, so it really can't do anything. The thing that might affect you would be seeing the sun earlier than usual or later than usual. You just have to adjust.

How do you travel to different time zones at the same time? Meaning, how are you in two or more places at once? :)

nicely first of all, it is the acceptable classification, besides the shown fact that a number of your questions approached the subject in a greater philosophical tone. first of all, you will desire to alter your know-how of time. Time is a length, in simple terms like the three spacial dimensions. there isn't any quantum of time (different than in some quantum concept; and it relatively is lots smaller than the nanosecond then), so asserting that there would desire to be countless worlds in each and every nanosecond is incorrect. on the belief of no count if or not traveling returned in time can impression activities sooner or later, it relatively is a count of opinion. in case you have faith that there is in ordinary terms one universe in which you progression forward or backward in time, than particular, the flaws you do in the previous can impression the destiny. yet this of direction consequences in the "grandfather paradox" you pronounced, in which you kill your self or an ancestor of yours, making it so as which you have been by no ability born. yet of direction, in case you have been by no ability born than you will desire to not have killed them in the 1st place. One answer to this paradox is that whenever you circulate returned and adjust time, you create yet another universe. as a consequence you may kill your mum and dad in this new universe, and you isn't born in this new universe, however the single from which you got here will stay the comparable. particular, the Earth is in consistent action (and centripetal acceleration), so in case you went returned in time the Earth may well be in a diverse place. yet of direction you will desire to assume that in case you have been waiting to holiday in time, you would be waiting to be certain you went to the acceptable region to boot.

The only affect would be a "clock time" lag or acceleration.
Your biological time would remain the same.

I have found going West is easier than going East. I guess because your going "back" in time. However, you will have to sleep for a while just to get over those damned airline seats.
