If you are not receiving high or low resting heart rate notifications, please ensure that:

• The feature is enabled.
• The minimum and maximum thresholds match the values that you have set. 
  The normal heart rate is between 50 and 100 bpm, but these figures may vary depending on the person. You can change the high and low heart rate thresholds in the Withings App.
• You were in a rest period. A rest period is a timeframe of 10 or more minutes of no activity, which can include walking, cleaning, or reaching for something (such as a glass of water by your bedside). Please note that any such activities can 'reset' this rest period.
