Desynchronization of the Circadian Rhythms

[Ewigkeit]

When external time cues such as day-night, sleepwake,
and mealtimes are inconsistent, a desynchronization,
or mismatching, of the circadian biological
rhythms occurs. This internal desynchronization disrupts
the timing of physiological and behavioral activity,
which in turn causes chronic fatigue, disrupts sleep
patterns, and causes decreased performance and coping
abilities. An example of desynchronization is that
of the newborn, whose biological rhythms are not
established until 3 to 4 months of age. At this point,
infants will start to develop longer sleep periods at
night and become more predictable in their waking
and sleeping patterns.
     Additionally, it is very likely that the semiannual switching of clocks between standard and daylight saving time contributes to the desynchronization of the circadian rhythms.

Ahh yeah, but normally one in good health can adapt.

But it all depends how the sympathetic/parasympathtic can function properly.

Many times the adrenal glands will affect how we can adapt to this change. If we put too much on them, by means such as alot of stress, lack of exercise and poor diet, it can throw the whole body out of harmony, by putting way too much on them to properly handle the changes.

Actually, the book from which I got the above information discusses a myriad of factors that can affect the circadian and other biological clock rhythms.
