hj1981: my understanding is that if you're comfortable, then your temp is not affected. IE if you wake up shivering because of the ac (or if your heater went out on a cold night) then your temp might not be so accurae. Or, if you woke up sweating because somebody turned up the thermostat and you didn't kick your cover off overnight. If that happens, still take the temp, but make a little note on your chart.

FionaJill: good luck!
