I see a lot of posts saying that HRV lowering over time means you're getting sick, but I haven't been feeling that at all. However, I have been upping the intensity of my weight lifting lately, and I'm wondering if it's because my body isn't recovering properly that my HRV is slowly going down overtime. As a side note, I workout 6 days a week with only 1 rest day (50 min sessions), so I'm not sure if I'm basically overdoing it?
Possibly ,but also you might overstress your body for other reasons.
I have been in such situation for the last two weeks before my recent half-marathon. Too much stress from travel, hiking in the mountains, a bit overtraining, heat stress, a nasty situation where my previous phone had the screen matrix destroyed, some minor malfunction of my motorcycle and a few bad sleep nights due to all of this.
After finishing the half-marathon and a few days of almost complete deload (only walking as an exercise) my HRV very quickly returned to normal and now it is within reference range
