Resting Heart Rate Increase (Charge HR)

[Nicole_Cross]

Does anyone know why this could be happening? For the past few months, my resting heart rate has consistently been between 69-72. Now for some reason it is increasing daily, and I have not changed my routine at all. (I workout 4-5 times per week; average 13-14,000 steps per day) Typically your resting heart rate is supposed to decrease when you're more active. I know my Fitbit is not always going to be 100% accurate for measuring things like this, but I'm still curious. Any thoughts?

Hi, it's a mystery to me. Though, for me it settled down to a more
understandable relationship between lowest heart rate during the day and
lowest heart rate while asleep.
If I'm under pressure my lowest heart rate also can easily be 60 but if I'm
not it can get down to 49. That seems to have a big effect on the 'resting
heart rate' calculation (mine can be between 62 and 72).

Thank you for your response. I fill a bit reassured now.

Your rhr appears to be incredibly low. Are you athletic?

@Babak_1234, many folks, myself included, have found our resting heart rate increase if we were getting sick; how have you been feeling recently?

FWIW, the Fitbit RHR calculation is virtually always higher than your minimum heart rate while sleeping.  Looking at my recent heart rate graphs on my phone, I see the following:

• Sleeping Heart Rate minimum (five minute plot): 33-35
• Resting Heart Rate: 41-43
• Today's Resting Heart Rate: 41
• Last Thursday's Resting Heart Rate: 45 (I was feeling a bit ill, nothing serious though)

Hi
Thanks for your thoughts. Athletic? Well I own and ride a horse so that’s a quite good for strength and cardio. As it happens it turned out I was starting with something a bit like flu and now that has passed my HR seems much more normal.

Yes, mine seems to be mostly back to normal.... stress maybe, I'm pretty athletic so it shouldnt spike.

For my 2 cents, at some time the Fitbit did start reading my heart rate closer to the pre January numbers, so think they likely played a little with the algorithms and worked it out.  The fit bit still reads just a tad higher now than a manually taken resting heart rate by doing an average of 3 HR's taken within 10 minutes of waking before becoming active.  For women, we often have an uptick on the Heart rate with our monthly cycle and hormones, and seeing a range 5 to 6 beats is pretty standard.  My HR is also very low so maybe it doesn't work as consistently when someone is athletic and has a lower HR than standard.  Manually measure I'm below 50 for a rhr, with the fitbit i'm 50 to 56 for a RHR.

Thanks for your comment. It’s a subject that has certainly provoked lots of interesting comments.

Dehydration is the simplest answer as the heart has to pump a little more to deliver the same volume for any given task including resting. In England recently we have had exceptional weather and this will compound the hydration issue as cooling the body requires more effort especially if dehydration is also a factor. Colin

Hello everyone! Thanks for sharing all of your experiences regarding your resting heart rate. I'm glad to read that it is showing accurate numbers for you. I'm also glad to read all of the interesting comments on this thread regarding this topic.

I just wanted to leave this helpful article here which is about resting heart rate. You will find some details about how it gets tracked.

Also, you might find this other article interesting. It's the All About Heart Rate article from the American Heart Association.

Hope you find this interesting! See you around!

Does anyone know what is going on with this increase of heart rate? 

[Melsville]

Has anyone checked into this, my heart rate was in mid 60's but in past few weeks has jumped to 80's!! No changes in lifestyle.

I found out what caused my increased: hyperthyroidism!

I think it was because of stress. My heart is back to normal now. Stress can have impact on heart for weeks. Just eat healthy and sleep, try to relax or calm down. I read the bible that helps. Then in about three weeks, it goes away. 

[Melsville]

Thank you, it has gone down to 77, and I agree stress could be a factor as my son just started uni and is unsure of course selection.

[Sukebind]

Actually it was hyperthyroidism but thanks anyway.

This is happening to me now. thyroid was already checked. The only thing that has happened recently was my CNS was overloaded. I was in full body temors for a week. The tremors are gone but I guess my CNS is not totally back to normal? The climb in my resting heart rate is making me nervous. Went from 63b to 73bpm in the past week 

[Sukebind]

I hope you’re feeling better soon. Does sound very like hyperthyroid. Best wishes.

Hello everyone! Thanks for your continuous participation on this thread regarding the increase in heart rate. Thanks for sharing your experience here and the reasons why you were having this.

Yes, there are several external factors that can influence and increase your heart rate. Fear, anxiety, stress, certain health conditions, caffeine, alcohol, and others. You can always check with a doctor if your heart rate continues to be high for a long time.

To lower it, you could try making some breathing exercises to relax yourself. Breathe in for 5-8 seconds, hold that breath for 3-5 seconds, then exhale slowly.

Hope this helps. Keep me posted!
