Every symptom is your body reporting one of two things: a good signal is missing (deficiency), or a bad signal is present (toxicity). Once you can name which, the path forward gets simple.
Signals of Deficiency
Fatigue, cramps, poor sleep, brain fog, low mood, slow healing — often a good signal missing: a nutrient, light, movement, or rest.
Signals of Toxicity
Headaches, skin issues, sensitivity, inflammation — often a bad signal present: a metal, chemical, food, or stressor the body is working to clear.
This is education, not medical advice. Persistent or severe symptoms deserve a qualified clinician.
