Well Health Hub — Evidence Guide

Why am I still tired when my labs look normal?

Track sleep, energy, meals, hydration, stress, movement, medicines, and symptoms for 14 days — then bring clearer observations to your next healthcare conversation.

Why this guide

Fatigue is a symptom, not a diagnosis. Patterns reveal what single tests cannot.

Evidence-informed

Every category in the tracker reflects documented contributors to persistent fatigue: sleep quality, circadian timing, nutrition, hydration, stress physiology, movement, and medication effects.

14-day window

A single day rarely shows a pattern. Two weeks captures the sleep and energy cycles, weekly routines, and input variations that a one-time snapshot misses.

Built for the conversation

The tracker helps you arrive at your next appointment with organized, specific observations — not vague descriptions that are difficult to act on.

What you track

Eight categories. One organized document.

Sleep quality and timing
Energy across the day
Caffeine and stimulants
Meals and nutrition
Hydration
Stress and emotional state
Movement and activity
Medicines and supplements
Notable symptoms

From the Well Health Hub Guide

“Normal results mean the test answered the question it was asked. They do not rule out everything. Fatigue usually has more than one contributor — and finding the pattern is the first step.”
