Topic relationship matrix
Wellness is a system, not a list.
Every cell captures a real, bidirectional relationship. Follow a row or column to see how one domain quietly shapes the others.
| Sleep | Heart | Stress | Inflammation | Brain | Longevity | Digestion | Metabolism | |
|---|---|---|---|---|---|---|---|---|
| Sleep | — | Strong Consistent 7–9h sleep lowers blood pressure and CV events. | Strong Sleep debt sensitizes the stress response the next day. | · | Strong Deep sleep clears metabolic waste linked to cognitive decline. | · | · | Strong One short night worsens next-day insulin sensitivity. |
| Heart | Strong Consistent 7–9h sleep lowers blood pressure and CV events. | — | · | Strong Low-grade inflammation is a shared root of atherosclerosis. | · | Strong Cardiovascular fitness is the single strongest longevity signal. | · | Strong Insulin resistance drives CV risk. |
| Stress | Strong Sleep debt sensitizes the stress response the next day. | · | — | Strong Chronic stress raises IL-6 and CRP. | · | · | Supportive The gut-brain axis links mood and GI symptoms. | · |
