The interpretation layer between
indoor environments and human biology
The biological brain
for indoor environments
HearthlyLabs reads the everyday signals a space gives off — light, air, temperature, humidity, sound — and translates them into evidence-grounded guidance on how that space is likely to affect your circadian rhythm, sleep, cognitive performance, and recovery.

Exposome Intelligence
≡ Exposome + AI
The exposome is your cumulative environmental exposure over time, and what it does to your biology. A tool that forgets yesterday cannot read it. HearthlyLabs is built on the four things the science requires.
01
Accumulate
Every reading builds one continuous picture of a space over time.
02
Personalise
Interpretation is anchored to your own body clock, not an average.
03
Fuse
Five signals combine into a single environmental-load number.
04
Explain
Every reading opens to its mechanism, evidence, and confidence.
Grounded in peer-reviewed research

Most lifetime environmental exposure happens in spaces almost nobody understands.

AI is “the Apollo Guidance Computer of the exposome.”
Explainable by default
Every reading opens to its evidence
Pattern, mechanism, likely impact, and how confident we are. Directional, never deterministic. HearthlyLabs interprets the environment, not you.
Five signals, fused to one number that grows with you over time.
Per-signal precision
Each signal reports only what its own evidence supports
Every claim is scoped to the outcomes the primary literature actually establishes, and labelled with how strong that evidence is.
Circadian regulation and sleep timing; daytime alertness and mood
Higher-order cognition and decision-making — not mood. CO₂ is a ventilation proxy
Cognitive performance, focus, fatigue, comfort
Attention, cognition, mental load, autonomic load
Comfort, respiratory & mucosal health — not cognition directly
Grounded in peer-reviewed science

We measure the environment
We personalise the interpretation
