Why it matters
An afternoon mood crash that happens predictably around the same time is almost always tied to your physiology — blood sugar, cortisol, adenosine — rather than your circumstances. The 2pm to 4pm window is a natural low point in the human circadian rhythm, but how low it goes and how you feel during it is individual. For some people it's barely noticeable. For others it's debilitating. The difference is usually in the morning's nutrition, sleep quality, and what's happening in the body leading up to that window.
When Normal helps
Normal tracks your mid-afternoon mood alongside your morning habits, sleep, and food over time. It finds what consistently determines whether your afternoon dip is mild or severe — and whether there's something specific you can change to make it better.
How Normal finds it
Tell Normal how you feel in the afternoon every day. Tell it about your morning — what you ate, how you slept, how you moved. Over three to four weeks it finds the morning habits that most consistently predict your afternoon mood.
