HRV (heart rate variability)

HRV (heart rate variability)

Heart rate variability (sometimes also called heart rate variability) refers to the ability of the organism to change the frequency of the heart rhythm.
A healthy heart is able to adjust to internal and external influences and constantly adapt to current requirements. If you are physically or mentally exerting yourself, this usually leads to an increase in heart rate, which then decreases again when you relax or take a load off. HRV can therefore be seen as a reflection of a functioning but also a disturbed autonomic nervous system. For example, there is a connection between a reduced HRV and post-infarction mortality.

A high HRV can be understood as a higher adaptability of the organism. However, due to chronic stress, this variability is often more or less limited. This influence of stress is the reason why an improvement in HRV is often sought, for example, through relaxation exercises such as breathing training. Through relaxed breathing, stress decreases and HRV increases. It is also very useful to display the breaths per minute, in order to determine at which breathing rate a client has the best HRV.

The chip should help the heart to quickly adjust to internal and external influences and to permanently adapt to the current requirements.
