Weekend drift is a signal, not a harmless reset.
Weekday versus weekend sleep drift can be more useful to watch than treating one long sleep-in as proof that the week has been fixed.

Thirteen threads. One living evidence map. 十三条生命线，一张持续进化的健康证据图谱。
We connect papers, evidence syntheses, trials, guidance, and public-health signals across thirteen fields—then ask how each meaningful change can serve everyday life.
汇聚论文、证据综述、临床试验、指南与公共卫生信号，并持续分析每项重要变化如何服务于日常健康。

The Thirteen Threads · 十三领域
Every frontier update has a home.
每一项健康前沿，都有清晰归属。
The fields are stable entry points, not isolated silos. One study can have a primary thread and several connected threads, preserving the relationships between sleep, food, movement, environment, mood, and social life.
Diet
饮食、营养与食品健康
Food composition, processing, portions, dietary patterns, and food context.
Sleep
睡眠与昼夜节律
Duration, regularity, timing, recovery, measurement quality, and circadian context.
Mood
情绪、压力与心理福祉
Stress load, recovery, emotional variability, and connected daily context.
Exercise
运动、体能与身体活动
Planned exercise, everyday movement, strength, aerobic fitness, and recovery.
Meal Timing
进食时间、断食与代谢节律
Eating windows, fasting evidence, schedule context, and circadian alignment.
Hydration
水分与体液平衡
Fluid intake, hydration assessment, climate, activity, and measurement context.
Tobacco
烟草、尼古丁与吸入产品
Combustible tobacco, vaping, second-hand exposure, and changing guidance.
Alcohol
酒精与饮酒模式
Dose, drinking patterns, sleep and mood context, and public-health guidance.
Body
体重、身体成分与代谢健康
Weight trends, body composition, waist measures, and measurement uncertainty.
Air Quality
空气污染与环境暴露
Particulate matter, smoke, indoor and outdoor exposure, and local context.
UV
日照、紫外线与皮肤健康
UV exposure, sunlight timing, skin protection, and environmental measurement.
Social
社交连接、孤独与健康
Connection quality, loneliness, support, social rhythms, and wellbeing.
Sedentary
久坐行为与日常活动
Long sitting bouts, movement breaks, standing, incidental activity, and workouts.

What we are investigating next.
我们接下来准备深入研究的问题。
The thirteen fields are the stable map. Radar dossiers follow interesting questions that cross several fields before the evidence is ready to become a formal note.
7 traceable notes
Latest evidence translations.
Each note remains attached to its source, primary field, connected fields, and a practical observation path. Comments are anonymous by default and appear only after moderation.
A workout does not erase a day of sitting.
Workouts and sedentary exposure describe different parts of the day, so one should not overwrite the other in a 7-day self-tracking view.
Read noteSleep regularity may matter more than one perfect night.
Device-measured cohort evidence suggests timing consistency can carry more signal than overreacting to one unusually good or bad night.
Read noteMeal timing is a context signal, not just a calorie container.
Later first and last meals were associated with higher cardiovascular risk, but timing still needs sleep and schedule context before it means much.
Read noteUltra-processed food risk is a signal, not a personal verdict.
What an umbrella review can tell us about broad population patterns, and why a 7-day ledger should track context instead of pretending to diagnose diet quality.
Read noteSitting time and movement are related, but not the same signal.
The sitting-time literature is a useful reminder that movement minutes and sedentary blocks should be logged separately.
Read noteThe sleep-duration curve is U-shaped. Your night is still noisy.
Why short and long sleep can both correlate with risk in population data, without turning a single night into a diagnosis.

01
Source traceability
Every claim stays connected to the paper, synthesis, trial record, guidance, or public-health source behind it.
02
Evidence stage
Preprints, observational studies, trials, reviews, and guidance occupy different positions in the evidence map.
03
Daily translation
Important changes become understandable context and, when useful, a low-friction observation in the App.
