The wearable devices that integrate with NC° measure not only your temperature data but also your heart rate. If your sleeping heart rate is unusually high or low, it likely means that your temperature may also have been affected.
If this is the case, the Natural Cycles algorithm will adjust your temperature, and you’ll see the text ‘Adjusted by the algorithm’ along with the wrench icon in your Add Data page.
If your temperature has been adjusted, there is no need to exclude it (even if you feel hungover or sick). That is because the temperature adjustment takes into account the deviations that occur during the night.
