“The biological clock is fixed intervals recurring physical event. Of these, human numerous examples. Heart rate is an example of a short cycle, menstruation is an example of a longer one. When a rhythm is daily called this circadian. the best example of this is the sleep-wake rhythm which occurs in virtually all animals. This is controlled by the hypothalamus .

“With-shift work at night and traveling with large difference in time zones are a major disruption of the biological clock. For long journeys usually occurs at an adaptation of the rhythm after three to five days especially enforced by light intensity.

For this, the hormone melatonin responsible, which is produced by the pineal gland near the hypothalamus. At decrease in light intensity is made more melatonin. This hormone causes drowsiness. This phenomenon does not perform in shifts. Tension, stress and pain all affect the hypothalamus. This sleep can be problematic. Usually the total sleep time is less. Often sleep more restless and less restorative. ”
