Breathing with regularity increases your HRV, by making your heart rate follow a sine of high amplitude, instead of being random, something like this.

It's sad that the smartwatches don't measure HRV. Otherwise this would be a nice group experiement.

Yes, I've also been looking for that without success. Some apps claim to measure HRV using a phone camera, but it seems to be mostly a scam. It looks like you have to go with either a chest strap, an ear pin, or a thumb sensor
