Body Battery

My Body Battery levels are always below 50, even after a full night’s rest and a day of reduced activity. Any suggestions? How can I verify the device readings?

Body Battery use stress readings to charge/discharge. What does your stress readings look like? The stress readings are the blue and yellow in the body battery graph. During sleep it should be all blue (which is below 25). If it is blue, body battery will charge. Orange readings will discharge the battery.

So, if I'm getting yellow during sleep does that mean I have a sleep issue? My body battery readings are rarely above 50 and more commonly 30 after waking up each morning. I have made an appointment with a sleep study center to determine if I have a problem in that regard. I definitely don't have the energy level I used to and although I'm nearing 70, I've been an active cyclist and runner, but my pace has diminished more rapidly than expected. Thoughts?

Something is affecting your HRV. There are many things that can have a negative impact on the HRV.

Here is my body battery graph from yesterday but most of my days look like that:

Blue is below 25 and will recharge body battery.

I had a little spike around 3 in the night and I think I was awake at that time for a few of minutes.

Thanks for the quick response. Here's my data from yesterday. No stress recorded during my run, but plenty during sleep. Seem counterintuitive.

There are no stress readings during activities. I'm not sure why, but my guess is that during that time the body battery is estimated in some other way.

There is a list with factors that will affect body battery.

Alcohol, nicotine, caffeine and such will have a negative impact on body battery.

I've restricted my caffeinated coffee to mornings now to see if that has a positive impact. No alcohol or nicotine for this guy.

Also medications, such as for example beta-blockers will mess up the HRV (and hence the Stress readings), food, fatigue, general stress during the day (seems to be rather high most of the day, in your case) will have impact on your sleep too. Sleep disorders, like snoring or sleep apnoe may induce high sleep stress too. Light and noise in the night won't help with the sleep stress either.

If the high daily and nightly stress does not correspond to your subjective feeling, consider consulting a specialist, or have a polysomnography test, to find out whether the data you get from the watch is right or completely wrong.
