About Adjust Sleep

Adjust Sleep was built with a singular mission: to make the science of circadian rhythms accessible, practical, and beautiful.

The Problem

Jet lag isn't just about feeling tired; it's a fundamental misalignment of your biology. For decades, the protocols used by elite athletes, astronauts, and military personnel to rapidly shift their internal clocks have been locked behind complex academic papers or expensive consulting fees.

Our Solution

We built an algorithmic engine based directly on the Phase Response Curve (PRC). By mapping your Core Body Temperature Minimum (CBTmin), Adjust Sleep calculates the precise mathematical windows where light exposure will advance or delay your clock safely.

Privacy & Design

We believe in tools that respect the user. That's why Adjust Sleep features a stark, minimalist design, zero external APIs, and performs all calculations locally in your browser. Fast, secure, and built for modern travelers.
