Since Dr. Wilson believes that low body temperatures cause the symptoms and since most patients complain of symptoms they are having during the day, Dr. Wilson recommends that the temperatures be measured during the day.

Body temperatures are normally lower in the morning, higher in the afternoon, and lower again in the evening. So if the temperatures are low during the day when they’re supposed to be at their highest, that’s better evidence that there’s a problem.

Temperature patterns are also important and illuminating. How patients feel can be affected not only by how high or low their temperatures are but also on how steady their temps are. This is especially important during T3 therapy. One temperature reading a day is not enough to see how widely the temperature is fluctuating, but more than three a day can be too time consuming.

For these reasons Dr. Wilson recommends measuring the temperatures

  • By mouth with a thermometer
  • Every 3 hours
  • 3 times a day, starting 3 hours after waking
  • For several days (not the 3 days prior to the period in women since its higher then) for diagnosis.
  • Every day during treatment.

Here is a convenient temperature log you can print out and use to record your temperatures.

For each day, add the 3 temperatures together and divide by 3 to get the average.

If your temperature consistently averages below 98.6 then you may be suffering from Wilson’s Temperature Syndrome.

Note: Some people believe that moving the thermometer around in the mouth very much can increase blood flow to the area and affect the temperature reading. It seems prudent to be mindful not to move the thermometer unnecessarily much.
