Charge 5 and HRV

[Keann]

This topic has been addressed as to earlier versions of Fitbit watches.  I cannot find a thread specific to the Charge 5.  I have been wearing my Charge 5 since Christmas.  I am 50 years old, reasonably fit.  I do yoga 3-5 times a week and walk every day.   My RHR is in the mid 70s, which seems a little high to me.  I do not sleep well, and bought a Fitbit primarily to track my sleep and try to make improvements in the New Year.  Generally, I tend to have light sleep at the beginning of the night, with on average 3-4 period so REM sleep between 3 a.m. and 7 a.m.  My sleep score is usually in the low 80's.  

I am concerned about my HRV.  It has been very low every day since I have been wearing my watch.  My range is 13-18, with an average of 16.  I have been wearing my watch likely too tight, and adjusted the band this morning so that it is a finger below the wrist bone and can slide up and down my wrist.  

Has anyone experienced abnormally low HRV readings on the Charge 5?  I know this was an issue with past models.

Hi, welcome to the Fitbit Community forums, @Keann. 

Thank you for sharing your inquiry about the Charge 5 and HRV.  

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.

Although a significant drop in HRV may indicate that your body is experiencing stress, strain, or showing potential signs of illness, please keep in mind that Fitbit is not a medical device. I wouldn't worry if it's not a significant drop in HRV, but if you do feel it's and odd number that you're getting constantly, I recommend that you check with a medical professional. 

I personally experience a drop in HRV at times and I don't have any heart or medical conditions, but in my case it may be related to stress and my caffeine consumption. As mentioned earlier, it's always a good idea to check all of this with your doctor if you're having doubts as well. 

Have a great day.
