Does anyone know about HRV?

Does anyone know about HRV? My HRV can be anything from 16 to 26,27 ish....not great, but it is something I am working on.  All of a sudden, this morning, it was 41.  I know for my age (42), the higher the better, but I am a bit concerned that it has jumped from 25 to 41 overnight.  I have been doing PT sessions at the gym and walking 15k steps a day but should this have happened?

You can’t believe everything you read on the Internet though.

I would suggest those are common concerns I've seen mentioned by those in the HRV study fields - so they are good to consider and totally valid.

Hello @sheileen Welcome to the Community Forums! @MaryMac123 @Heybales It's great to see you around and thanks for your input! 

@sheileen HRV varies from person to person. Age, sex, sleep, hormones, circadian rhythm, and other factors (for example, caffeine or alcohol intake, exercise, and stress) can affect HRV.

Studies show that a higher HRV is linked with better health. A significant drop in HRV may indicate that your body is experiencing stress, strain, or showing potential signs of illness. In addition, this metric is the variation in time between heartbeats. If your heart rate is 60 beats per minute (bpm), it doesn’t mean that your heart beats once a second. Your autonomic nervous system (ANS) determines the timing of each heartbeat. We use the common formula called the RMSSD to determine heart-rate variability (HRV) from your heart-rate data.

Keep me posted.
