Why does my heart rate drop when laying down to sleep?

I have a heart rate/pulse ox monitor. I was using it to see my heart rate when excercising. I have been wearing it to bed to see my heart rate, and noticed my heart rate drops to the 50%26#039;s- 40%26#039;s when drifting off to sleep. This seems slow. It is normal 60-80 during the day. Should I be concerned about the low heart rate??????

No need for concern. It%26#039;s called Resting. Other body functions slow down as well. If your body kept functioning at the same pace at rest as when you are active you would constantly be tired and eventually have some life threatening medical issues. Rest is good, You can stop monitoring now and get some sleep.
