How does alcohol affect my deep sleep? Are my symptoms worse in days when my heart rate is higher? What are the top factors that affect my heart rate variability?

While wearables like Apple Watch give us lots of raw data on our health metrics, what really matters is insights into the underlying factors behind our metrics.

Today we’re launching a feature in Empirical Health that lets you correlate your health metrics with your symptoms and behaviors.

Correlations

In Empirical Health, correlations are now automatically shown between any health metric and other health metrics. On the Today screen, just tap on a metric to see its correlations, alongside its trend over time. This works for any Apple Watch health metric; support for blood tests or at-home diagnostics is coming in the future.

Tag your symptoms & behaviors

You can extend these correlations through tags, which let you track your own custom symptoms and daily activities. On the today screen, you can now add custom tags:

For example, if you want to see how dizziness correlates with heart rate, add a custom tag called dizziness, track it daily, and then after 6 days, you’ll see correlations.
