## The Science Behind Sorano
Sorano's algorithm is built on circadian rhythm
research and the concept of CBTmin (Core Body
Temperature Minimum) — the lowest point of your
body temperature cycle, typically occurring
2–3 hours before natural wake time.
## Why CBTmin Matters
light_before_CBTmin: delays your clock
light_after_CBTmin: advances your clock
By precisely timing light exposure, avoidance,
melatonin, caffeine, and meals around your
CBTmin, Sorano creates an optimal adaptation
strategy that can reduce jet lag recovery
time by up to 50%.
