I have a problem with my whoop detecting activities that I didn’t do, often having my heart rate be elevated for 20+ minutes (zone 3 or 4) when all I was doing was walking or doing chores around the house. I have the strap on tight. I can delete the activity from the main screen, but the strain and heart rate data still stays. Why doesn’t the data from particular activity get deleted when the activity is deleted?

Hi @GWake - When you delete an activity, it only removes the activity label (the interpretation), not the underlying heart rate or strain data. WHOOP measures strain based on your continuous heart rate throughout the entire day, regardless of whether an activity is logged.
So even if the activity itself is deleted, the elevated heart rate that occurred during that time still contributes to your daily strain. Things like walking, household chores, arm movement, stress, heat, caffeine, or even gripping objects can legitimately raise heart rate into higher zones and add cardiovascular load, even if it doesn’t feel like a “workout.”
Auto-detected activities are essentially an overlay on top of the heart rate data that’s already being collected. Removing that overlay won’t retroactively change your strain or heart rate graphs.
