Best thing I found was waking up, drinking a large glass of water (if allowed), having a hot shower and then keeping warm and moving until the finger pricks (dance, throw in some squats, pretend you're typing, etc).
Water is allowed, and they advise washing hands in warm water for 30 seconds to promote blood flow.
The problem with any of the rest of that plan (having a shower/etc) is that there's someone waiting on the doorstep for the blood sample. The swab for the PCR test takes less than a minute, but it was somewhere between 5 and 10 minutes to do the finger prick and get the amount they require (0.25ml to 0.5ml) which is a good 5 big drops of blood from a small lancet hole, and you're not allowed to squeeze the finger.
I think I'll have a bowl of really warm water to dip my hand in (but not the spiked finger) next time.
I had to dip my hands up to the elbow into the washing up tub for a few minutes, the lance just didn't generate a lot of blood. And just a bit of warm water didn't do it either.
