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 chart 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.

What kind of thermometers should be used?

Digital thermometers are very fast and convenient but can easily become inaccurate from:

  • dropping them from 4 inches or more
  • low batteries
  • exposure to water or humidity

When they become inaccurate they can still give a reading, it just won’t be right. There’s no way of knowing whether the reading is correct or not. Sometimes, a digital thermometer will show one reading one minute and another the next.

Mercury Thermometers are very consistent and they hold their readings. If patients are too busy to read their thermometers (while driving, for example) when it’s time, they can take the thermometers out and read them later.

Mercury thermometers can take longer (it’s good to leave them in for around 7 minutes). They are also being phased out of the market because of environmental legislation and are becoming harder and harder to find. The concern is that when the thermometers are broken the liquid spills out and some mercury vapor gets into the atmosphere, finding its way into the food chain. When broken thermometers are thrown in the trash and then incinerated, that apparently puts even more mercury into the air. One doctor believes that some mercury can make it through the glass of intact thermometers. She believes that some of her patients are especially sensitive to mercury and have noticed episodes of acute depression, headaches and malaise just from measuring their temperatures with a mercury thermometer.

We recommend some great new Liquid metal thermometers (not mercury). We think they’re better than mercury thermometers ever were. For one thing, they provide accurate readings in only 2 minutes! This is especially true if the thermometer is 72 degrees or warmer before you measure your oral temperature. If possible, it’s good to warm the tip of thermometer against your body for a couple of minutes before measuring your oral temperature. The reason you don’t want to put a cold thermometer in your mouth is that it will cool down your mouth a little, altering your reading.

If you have a different liquid metal thermometer, you can test it by keeping it in your mouth and have someone time the measurement to see when the temperature stops changing. However, leaving the thermometer in for more than 5 minutes or so will mechanically stimulate increased circulation to your mouth. That increased blood flow is coming from your heart which is one degree warmer. Therefore, your temperature reading could rise to an inaccurately high reading.

Glass Alcohol thermometers are very consistent but frequently don’t hold their readings. They usually contain a red liquid. These thermometers are fine as long as you read them right away.

The Big Picture

No matter what thermometer you choose, no matter how new, it may still not be perfectly accurate. There is always some variation among thermometers, some small, some large. The important thing is for patients to be able to see the changes in their temperatures with proper T3 therapy. Therefore it would make sense for patients to try to take their temperatures in the same way each time with the same thermometer for comparison’s sake. The Mercury, Galistan, and Alcohol thermometers are especially good for this since they are so consistent. The liquids they contain are going to expand with warming the same way every time (make sure to shake down the Mercury and Galistan before each use to reset them). So even if a patient has a Mercury or Galistan or Alcohol thermometer that is a little inaccurate, at least it will be consistently inaccurate and in that way still useful (in showing the improvement in temperature with treatment).

By the same token, if your story is consistent with Wilson’s Temperature Syndrome and you find your temperature is normal, by all means check it with another two or three thermometers! Many patients have found that their thermometers were wrong and their temperatures were low and they have responded well to treatment. In fact, if your history is classic for Wilsons Temperature Syndrome your chances of having a normal temperature are only about 1 in 200. There’s a lot better chance that your thermometer is wrong than there is that your temperature’s normal.

These issues of thermometer accuracy don’t come up very often but they come up often enough that doctors and patients would be well served to know about them. For the most part, patients are easily able to see that their temperatures are low before treatment, that they come up with treatment, and that their complaints begin to disappear as their temperatures improve.
