Track the Phoenix calm rating separately from other subjective outcomes. Compare the interventions attached to each exact measurement before choosing what to test in yourself.
How to read this
Phoenix research is longitudinal and observational: we follow real APOE4 carriers over time and compare each member with their own earlier self, with no placebo group, no randomisation, and members choosing their own interventions.
That means these are strong signals pointing at what to test next, not proof of cause. Most nutrition, supplement and lifestyle research you read online has exactly the same design. The difference is that we say so, and we show you the confounders.

Phoenix daily check-in calm score · Aim: higher
Got sunlight
—Neutral resultGot-sunlight tags showed no measurable calm benefit across 64 women and stayed flat to slightly negative at every support floor.
0 selected member cases · not a response rate
Women with got-sunlight tags and comparable calm ratings at the tested support floors.
Sauna plus breathwork
—Neutral resultHabit combinations, including sauna plus breathwork, did not outperform their best single ingredient in Issue 01.
0 selected member cases · not a response rate
Members with sufficiently dense paired habit and calm-score data for a combination comparison.
These historical records remain beside the current evidence so you can see why their status changed.
Breathwork
!Context affected this recordThe Breathwork Believer averaged 7.9 calm points on 34 breathwork days versus 6.4 across 26 comparison days, with sauna often co-occurring.
Breathwork Believer · APOE4/4 · male · age 60-69
Calm averaged 7.9 on 34 breathwork days versus 6.4 across 26 comparison days, with sauna often co-occurring.
What else changed: nearby starts included sauna.
Next study: repeat Calm rating after a dated Breathwork window.
1 selected member case · not a response rate
The curated Breathwork Believer comparison of breathwork and non-breathwork days.
1 selected case shown with this evidence.
Sauna
!Context affected this recordThe Breathwork Believer's sauna days averaged 1.64 calm points higher, but sauna and breathwork often occurred together.
Breathwork Believer · APOE4/4 · male · age 60-69
Calm averaged 1.64 points higher on sauna days while breathwork often occurred alongside sauna.
What else changed: nearby starts included breathwork.
Next study: repeat Calm rating after a dated Sauna window.
1 selected member case · not a response rate
The curated Breathwork Believer comparison with co-occurring sauna and breathwork days.
1 selected case shown with this evidence.

Alcohol
↘Opposite directionThe Pattern Spotter's drinking nights averaged 1.72 sleep-quality points lower across 25 drinking and 35 comparison nights.
Pattern Spotter · APOE4/4 · female · age 60-69
Sleep quality averaged 1.72 points lower across 25 drinking nights versus 35 comparison nights.
What else changed: no nearby starts were recorded.
Next study: repeat Subjective sleep quality after a dated Alcohol window.
1 selected member case · not a response rate
The Pattern Spotter's drinking nights compared with her own non-drinking nights.
1 selected case shown with this evidence.
These historical records remain beside the current evidence so you can see why their status changed.
Alcohol
!Record withdrawnAn apparent alcohol-improves-deep-sleep result dissolved under device-coverage checks and is retained only as a retraction.
0 selected member cases · not a response rate
Historical alcohol-tagged wearable nights before corrected device-coverage checks.
This result was withdrawn: The positive deep-sleep result was a wearable-coverage artifact and remains excluded from active evidence.

Forty carriers with a dated start and a repeat blood test close it. Creatine, vitamin D3 and B12 sit further back. Your next blood test is somebody else's answer, and theirs is yours.
