Every morning I check my heart rate on my fitbit tracker/app on my iPhone. Yesterday morning I found it as low as 38 BPM. Is that normal?

It only happened once before and was wondering if a resting heart rate should go down so low. Normally my resting heart rate can go down to 50 during a nights sleep. But 38 BPM seems too low.

Anyone know anything about this sort of thing?

YES 38 is way to low

Your heart is showing some weakness
see a doc

  • Why does my iPhone 5s freeze every morning? The last few days I have turned on 5 or 6 alarms in the morning because I have trouble waking up since school started. Every time they go off, my screen freezes and jitters every time I try and turn them off or unlock my phone. If I restart it, it's fine but even that is hard to do since I can't slide the power off button due to the freezing. It's less than a year old. Does anyone know why this is happening and/or how to fix it?
  • What's a good heart rate variability product? I started using the Elite HRV app for iPhone and the chest strap heart rate monitor that is made by Polar. What's your experience with HRV biofeedback and do you have any insight you can offer me about products that work especially well and tips on training?

  • Is this a normal heart rate? I used this iPhone app that supposedly can check your heart rate by having you put the tip of your finger on the camera lens and it said my heart rate was 88bpm. I don't know how accurate this is but if it is, I'm 18, 5'4" and weigh 145. Is this an okay number? I heard 60-99 is normal range for resting bpm but I just wanna make sure…
