These cues include periodicity of:
- "...scientists have warned that modern life and 24-hour society mean many people are now "living against" their body clocks with damaging consequences for health and wellbeing.
We are the supremely arrogant species; we feel we can abandon four billion years of evolution and ignore the fact that we have evolved under a light-dark cycle. "
When it comes to our survival, our body works over longer periods than 24 hours - it has to prepare for periods of days weeks and months. It has to make sense of the world from energy flows, hormonal flows, and, other signals that pulse, ebb and flow in response to external forces. These signals hold information.
If the signal isn't clear then our body will be confused by noise - the noise of persistent grazing, persistent indolence, persistent temperature exposure, and yes, persistent light of an eternal summer - trapped in a state where it prepares for a lean times that never come.
Lean times signal repair, renewal and regeneration.
