I know that feeling, waking up just minutes before a set time mark. But I ,lost that "ablity", perk, skill, whatever it is, over the past years.


Constantly changing sleeping patterns, like rotating shifts at work, can probably be a long-term health hazard, if the changes are too extreme. Especially the nervous system can be shpwign symptoms of many divers elinds after many years, even decades. This can further affect the immune system. Everything gets out of tact, out of synch. Its not before much later that the consequences show - and then are extremely difficult to be associated with what originally has caused them.



So I think its mor eharmelss to have extrnmeely deviating sleeping-waking patterns, but being constant in these, then to always have to alter these patterns and then very signficantly so. Keep a rythm,. however that rythm may be for your idnovidual nature - but if possible avoid to constantly change that rythm dramatically.



There is also an association with neurotransmitter levels going frenzy if these patterns get notoriously altered, and drastically. Lats b ut niot least, sleep is for allowing the brain to detox. It shrfinks a bit, so that the liquor inside the skull can easier wash around the brain and wash away the sub-molecular chemical "waste" from neutrotransmitters build and used over the waking phase, and then not getting properly re-synthesized. Itsnot so much muscular regeneraiton that forces us to sleep, for that, just resting would be good enough.
