"General anesthesia during surgery can cause sleep disturbances, and symptoms of jet lag. General anesthesia can lead to other "temporary" disturbance. Such metamorphoses of the body are related to the fact that anesthesia can shift circadian rhythms, and after this happens impaired perception of time". This statement biologists, was published in the journal Proceedings of the National Academy of Sciences, which is quoted by the RIA "Novosti".
The genes that are responsible for the daily (circadian) rhythm of the human body were discovered in the last century in the 90-ies. A group of scientists, administered guy Varnanam employee of the University of Auckland (New Zealand) investigated the effects of a complete "blackout" of the body during the stay of the person under General anesthesia on a "biological time".
As it turned out, most people are experiencing the hardships of so-called "syndrome" change time zone", which arise directly after surgery using General anesthesia. Come to the patient is unable to determine how long he was under anesthesia, and its circadian rhythm arbitrarily shifted.
Wahrman with colleagues tested, not does the effect of anesthesia on the circadian rhythm of animals. Result was a series of experiments on honey bees. The activity of insects in all cases was broken because of the "stop the biological clock.
Bees, regained consciousness after anesthesia, tried to return to their hive, but was flying in a completely different direction with a shift of about 90 degrees (this is the distance the Sun has time to go for a full six hours). And watch collecting nectar and cycle activity/rest moved about hours 3.5-4.
Scientists believe that anesthetics do not isolate the biological clock, but only slow them down or simply shift. That explains the unpleasant effects after General anesthesia experienced by patients.
