One of the apps I use daily is a nifty sleep tracker called Sleep Watch. One of the things it tracks is “heart rate dip” during sleep, compared to average heart rate during the day. Supposedly, the more the HR dips during sleep, compared to while awake during the rest of the day, the healthier it is for a person.
I’ve noticed that if I don’t do any rowing during the day, I get a sub-optimal HR dip. If I do a moderate amount of rowing, I get a “normal” dip. If I do a LOT of rowing, like either a leisurely half marathon or a shorter distance but at a higher effort level… I will get a greater than 20% HR dip and will be commended by the app for having done a “Good job!’.
Today’s rowing was 10K at an easy pace, with the goals of finishing the entire distance and keeping heart rate at least 100 and below 140. Much of the time today, I rowed with eyes closed.
Happy rowing to you and may you have healthy heart rate dips as a result.
