So you reckon that daytime pulse in the 80's is higher than it should be?

I don't know if this is a factor, but we are in the middle of a heatwave here,and it was 40 degrees Celcius today. I only have aircon in 2 rooms,and the rest of my home is sooo hot. Just walking around cleaning or doing anything else around the house makes me perspire.

I also looked pulse rates up on google andit said 60-100 as normal???
