## What is Lagless?

Lagless builds a day-by-day plan to reset your body clock after a flight — when to seek light, when to avoid it, when to stop caffeine, when to sleep.

The plan follows published circadian rhythm research. It works out your body's natural low point and builds a light and sleep schedule around it, shifting as fast as your body can safely adjust.
