Resting heart rate on my Inspire HR has increased over a few days even when I do the same routine

I have recently purchased an Inspire HR and on the first day I had it, my RHR was at a rather normal 65bpm. Over the last few days though, my RHR has increased to 70 after waking and then 72. This doesn't make much sense to me and it is kind of worrying since I regularly exercise and keep the same routine every day, and yet my heart is having to work harder rather than the opposite. Although I don't think it'll come to this, I have been thinking about seeing a doctor as my RHR is higher than I'd like, especially after good, regular exercise. My band is snug against my wrist and in the correct spot shown on the manual, so I don't think the problem is inaccurate readings. Should I be worried about my increasing RHR?

Are you talking about the RHR that the algorithm provides in the HR tile or just your HR when you are sitting still?

I'm referring to the RHR that the Fitbit app tells me when I open the app. I check it right after waking up every morning and even though my HR was in the low 60's this morning my RHR is listed at 72bpm. I don't know if my HR spiked or what, but I'm kinda worried.

Personal experience with RHR rising:

1. When I get a cold or flu I find my RHR rises about a week before any physical symptoms. It is a gradual rise of 1 to 3 points on a daily basis. Total rise can be as much as 15 bpm.

2. 'Stress' over an upcoming event - good or bad. Vacations, trips, change in job, retirement, house move. Once again I usually see a steady rise in RHR about a week or two before the event. Last year the wife and I went across the pond for a cruise. A couple of weeks before we went on the plane my RHR rose steadily until a total rise of about 12 bpm and stayed elevated until a week after we returned. I also saw about a 15 bpm rise a couple of weeks before hernia surgery.

3. I've read posts from women who got pregnant that said their RHR rose before they knew of their condition. So, yes, physical or health changes can cause it to rise. 

If you have no upcoming events that can cause stress/anticipation and your RHR continues to be elevated then it might be prudent to at least get some kind of checkup with a physician.

Thank you for the info! I'm pretty sure I'm not sick and there's no way I could be pregnant so it must be some sort of stress. I don't really know what I could be stressed about but it seems most likely. I may go see my doctor if my RHR keeps rising after weeks. Hopefully it's not a problem but you never know!
