Your “most days” symptoms are grouped together in a regular symptom check-in survey that you can complete as often as once a day, at a time that works best for you. Since these symptoms are typically present to some extent all the time, when Human Health analyzes your data for trends, we focus on changes in their impact over time between surveys.
For symptoms that occur only occasionally, we want to save you the trouble of repeatedly marking them as "not present" or "no impact" in your daily check-in. Instead, you can log these symptoms and their impact only on the days they actually occur using the Log Today feature on the Human Health homepage.
When Human Health analyzes your data for trends, we treat these occasional symptoms differently from your “most days” symptoms. For these, the frequency of occurrence primarily influences the impact score. We assume these symptoms weren’t present on days you didn’t log them, so your impact trend score will be higher the more often the symptom is logged. Make sure to log these symptoms whenever they appear!
