Acute stressors and HRV

Blog post by Marco Altini

Here are two examples of strong stressors that impact in a similar way morning HRV (collected with HRV4Training's camera measurement) and night HRV (collected with Oura rings)

As we have reported previously, as long as a few best practices are followed (using the whole night of HRV data for example, instead of just a few minutes), you should be able to gain the same insights from morning and night HRV readings.

​Pick what works for you, and use the same method consistently over time, in order to learn how your physiology changes in response to various stressors.
