HRV, paced breathing and cardiac coherence
With Kardia, you can practice heart rate variability (HRV) training through paced breathing. By breathing at a specific rate, around 5.5 cycles/min, your HRV increases and becomes regular. This state is known as cardiac coherence, or cardio-respiratory coherence. Scientific studies have demonstrated that it has beneficial effects on stress and anxiety level, blood pressure, depression and sleep.

The best breathing rate is different for everyone. With Kardia, you can set very precisely the exercise frequency, so you will just need a few tries to find out the value that gives you the best results.
