Circadian anchoring audit — morning light + sleep timing + caffeine — Boston.

Boston, MA is home to Harvard Medical School's Division of Sleep Medicine and Brigham and Women's Hospital, where Charles Czeisler -- whose landmark 1986 Science paper demonstrated that bright light resets the human circadian pacemaker independent of the sleep-wake cycle -- has directed sleep-medicine research for decades. A distinct connection from this library's existing Anchorage tile, which is built on that city's own extreme-latitude seasonal light swings rather than the underlying science's academic origin.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

1-2 week sleep-wake + morning-light + caffeine baseline (with day-to-day variability) + a coached anchoring plan (consistent wake time, morning light, evening dimming, caffeine cutoff), one habit at a time

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• a 1-2 week sleep-wake + light + caffeine log (or app export)
• note on shift-work / travel / known circadian, sleep, or mood disorder
• a lux estimate or time-outdoors record for morning light
• clock
• clinician-referral note for red flags

Steps

1. 1. Record the 1-2 week baseline: usual sleep and wake times and their day-to-day variability ('social jetlag'), morning light (time outdoors or by a bright window within ~1-2 h of waking), evening light (screens/bright light before bed), and caffeine timing + amount.
2. 2. Note shift work, frequent travel, or any diagnosed sleep/circadian/mood disorder — these change the plan and may need a clinician.
3. 3. Assess morning light: is there ~10+ minutes of outdoor/bright light within 1-2 hours of waking on most days? Flag the gap as the primary anchor.
4. 4. Assess caffeine timing: is the last dose >=8-10 hours before target bedtime (half-life ~5-6 h)? Flag late caffeine.
5. 5. Set a coached protocol: a consistent wake time (+/-30-60 min) 7 days a week, morning outdoor light, dimmer/warmer evening light, and a caffeine cutoff; progress one habit at a time.
6. 6. Record the baseline, the identified gaps, and the coached plan; sign. Route any red flag to a clinician (or crisis support).

What counts as done

• 1-2 week log of sleep + wake times with day-to-day variability ('social jetlag') noted
• Morning-light exposure (time outdoors/bright within ~1-2 h of waking) and evening-light habits recorded
• Caffeine timing + amount recorded and checked against a ≥8-10 h pre-bed cutoff
• Coached anchoring plan (consistent wake time, morning light, evening dimming, caffeine cutoff), one habit at a time, with red flags routed to a clinician

Proof is measured against these, not judged by taste.
