Or should I say, how long does it take to wear off? I drink coffee on and off all day. I also enjoy several double shot mochas throughout the week (got my own cappacino maker). I have noticed sometimes my RHR is around 48-52bpm. And, sometimes it seems to be up around 60bpm. I can only assume my caffeine intake is what does this.
After consuming coffee regularly, how long does it generally take for it to wear off so you get an accurate RHR reading?
