Shower measurement

Hi, I have a question for the community, I now have a whoop for about 2 weeks and i notice a really high high rate sometimes in the shower. Normally it’s a bit elevated that i ignore it but today it hit 200 bpm and stayed there for 7 minutes or so. Does anybody else experience this, and is it correct or likely a wrong measurement? Now I have a strain of 12 after only showering today.
