How can individuals differentiate between legitimate health data that should be input into symptom-tracking apps or wearable devices, and irrelevant or misleading information that could potentially impact the accuracy of their health monitoring over time?

Individuals can differentiate between legitimate health data by consulting with healthcare professionals to determine which symptoms or health metrics are relevant to track. They should also ensure that the symptom-tracking apps or wearable devices they use are backed by scientific research and have positive user reviews. Additionally, individuals should be cautious of any data that seems too good to be true or contradicts their own knowledge of their health status. Regularly reviewing and comparing the data from different sources can also help in identifying any inconsistencies or inaccuracies.
