Why won't my Body Battery charge?

How was your sleep last night? Middle of the day, work on relaxing and keeping that stress score down, that helps your battery recharge.

Try overlaying the stress scores on the body battery graph and you'll get a better idea of what is going on. I can have nights where my body battery doesn't fully recover but that is usually a) post night shifts or b) post a heavy workout. If you consistently drink alcohol on an evening, that imposes a reasonably large stress load. I went from a daily stress score of 50 when I was drinking a couple of beers per night to a stress score of 15-20 when not drinking daily. I can have an occasional drink (x1 per week) with no impact on my stress scores. I've been monitoring my stress scores for some time and they are crazy accurate, often picking up events that are unexpected. For example, with a recent man flu of 3 days duration, my stress scores hit the 30's before dropping back down to the usual 15-20.

beers is very stress for your body!

One beer is stress for body about one or two hours and battery will load after this stress . 

Check stress score you will see how huge impact have beers for your body and recovery

Please look at the charts:)

In this particular case, I have not been drinking alcohol, so it is not related to that but for whatever reason my HR and stress levels were running higher than normal for a few days. I had a late workout and got stomach flu or food poisoning so maybe that affected it. My body battery did charge more last night and is currently at 50 at mid day. So I will work on my deep breathing and meditation and see what happens!

Anymore word from Garmin on this? Mine has been fine till last few days

Same here after update to v5. I switched off and on and now it works
