Did an experiment on the dive reflex as part of an undergrad course in university; hooked up a student (volunteered and willing of course)to a heart monitor and put their face in a bowl of water.
Heart rate plummeted from 72 BPM (resting) down to 39. It was pretty cool to see

- docaholic 11y agoIf I recall correctly, it has to be done in cold-ish water! Warm water above a certain temperature doesn't invoke the dive reflex (I think we used water at 10 degrees Celcius for the experiment), although I'd have to read up on my experiment again to be sure. Sounds like a fun Easter activity :)
- soperj 11y agoI really wonder how far my heart rate would drop, since I'm in the low 40s at resting.
