Circadian and quantum biology impact health at every stage of life, but the earlier in life, the more profound the impact thanks to the way these factors program our epigenetics for either health or disease.

In circadian literature, there are two similar terms used to describe the rhythm. One is stability, as in Melatonin and stable circadian rhythms optimize maternal, placental and fetal physiology1.

The other is strength, as in Diurnal Cortisol Slopes and Mental and Physical Health Outcomes:A Systematic Review and Meta-analysis2.

What we are talking about is the regularity and the amplitude of the rhythms. This points to 2 distinct ways the circadian rhythm can be disturbed. It can be either irregular/regular and either weak/strong.

  1. Irregular circadian rhythm (unstable, entropic). This happens from odd schedules of all kinds, including time-zone traveling, weekend adventures, or occasional night shifts.

  2. Regular circadian rhythm (stable). This happens from keeping the same kind of schedule …
