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.

HRV，节奏呼吸和心脏连贯

通过Kardia，您可以通过节奏呼吸练习心率变异性（HRV）训练。通过以特定速率呼吸，大约5.5周/分钟，您的HRV增加并变得规则。这种状态称为心脏相干性或心肺相干性。科学研究表明它对压力和焦虑水平，血压，抑郁和睡眠有益。

每个人的最佳呼吸率都不同。使用Kardia，您可以非常精确地设置锻炼频率，因此您只需要尝试几次就可以找到能够获得最佳效果的值。
