{"product_id":"the-sleep-tracker","title":"The Sleep Tracker","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eYour sleep, quantified.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eMost sleep tracking lives on your wrist — competing with movement data, heart rate variability noise, and the bulk of a watch. The Somnos Sleep Ring sits where sleep science belongs: on your finger, where blood flow is stable, skin contact is consistent, and photoplethysmography signals are cleanest.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWorn through the night, it tracks every stage of your sleep architecture — light, deep, and REM — alongside blood oxygen saturation, resting heart rate, HRV, skin temperature deviation, and respiratory rate. In the morning, your data is waiting: a complete overnight report broken into the metrics that actually matter for recovery and cognitive performance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThin enough to forget you're wearing it. Precise enough to act on.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eTHE SCIENCE\u003c\/strong\u003e\u003cbr\u003eSleep quality cannot be assessed by duration alone. The ratio of slow-wave sleep to REM, night-to-night HRV trends, and oxygen desaturation events are the markers that predict next-day performance, hormonal recovery, and long-term health outcomes. The finger is the optimal peripheral site for optical sensing — the digital arteries run close to the surface, motion artefact is low compared to the wrist, and skin temperature here reflects core thermoregulatory shifts with high fidelity. The Somnos Sleep Ring captures all of this passively, requiring no input and no disruption to your sleep environment.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words
