I donated blood yesterday, and this morning I've seen big changes in my 
whoop recovery score: HRV down, RHR up, and elevated stress levels impacted my sleep. This is all super abnormal for me.

This is a dumb question, but how does the blood loss affect this?

My understanding is that when your blood volume dips (you donate blood) your resting heart rate might temporarily increase while your body works harder to maintain the blood pressure and get oxygen around the body.
