Science Summary

Low heart rate variability has been connected to worry and negative feelings, pain, and stresses at work [1-5]. On the other hand, higher heart rate variability enables you to recover more easily from stress, manage your pain [5], and boost your positive feelings and sense of wellbeing [2]. Higher heart rate variability is also beneficial to our ability to focus and concentrate, to think clearly [6].

The best way to increase your heart rate variability (HRV) is to calculate the 1 Best Breathing Rate for you at which Heart Rate Variability is maximal (your ‘Resonant Frequency’) and to train at this rate [3].
