apple watch giving false positives for fall alarm
My apple watch series 6 keeps on giving false positive alarms for fall detection even when I am bending and picking up something AND does not detect when I have actually fallen.
Did you try to unpair it and connect it again to your iPhone, setting it up as a new device?
Unpair and erase your Apple Watch - Apple Support
If this does not help, you will have to get the watch diagnosed by Apple:
