Why does my mood change so much?
Mood shifts are often connected to sleep, food, movement, light, cycle timing, social context, and stress load.

Mood guides
Mood is not separate from the body. The days you feel flat, low, irritable, or unusually good often have physical context around them.
These guides help you find which inputs most reliably change your mood and what your better days have in common.
Editorial note
How to read this guide
Normal guides focus on pattern tracking: comparing symptoms, meals, sleep, stress, movement, routines, and timing over repeated days so people can notice what reliably changes how they feel.
Normal is not a medical provider. This guide is for general informational purposes and should not be used as medical advice, diagnosis, or treatment.
