Everything You Need to Know about Wilson's Temperature Syndrome, Low Body Temperature, and Slow Metabolism

What is Wilson's Temperature Syndrome?

Wilson’s Temperature Syndrome is the first primary discovery made by Dr. Denis Wilson, co-creator of Fastercise. The syndrome causes a low body temperature and a slow metabolism that doesn't show up on thyroid blood tests.

What is Metabolism?

Metabolism is how your body converts what you eat and drink into energy. It is very important and having a slow metabolism can cause a lot of problems, including easy weight gain, fatigue, depression, dry skin, dry hair, tension, panic attacks, headaches, migraines, anxiety, among other things. 


What are the Symptoms of Wilson's Temperature Syndrome? 

People with Wilson’s Temperature Syndrome experience the same exact symptoms of slow metabolism or low body temperature that people get from hypothyroidism or when they don't have adequate thyroid gland function.


Symptoms Include:

  • fatigue

  • depression

  • dry skin

  • dry hair

  • fluid retention

  • easy weight gain

  • panic attacks

  • anxiety

  • itchiness

  • hair loss

  • brittle nails

  • easy bruising

  • sometimes asthma

  • sometimes premenstrual syndrome

  • poor wound healing

  • poor memory

  • poor concentration

  • low ambition

  • low sex drive

What Can Cause Wilson's Temperature Syndrome?

When your body goes through some kind of major stress, like starvation, childbirth, divorce, death of a loved one, loss of job, or family stress. The body recognizes this and goes into survival mode to conserve resources. As a result, the temperature will start to drop and metabolism will slow down.

Check Your Temperature:

There are only two ways that you can measure metabolic rate:

  1. Oxygen and Carbon Dioxygen Levels

  2. Body Temperature

A normal body temperature is 98.6°F, but there are 30% or more of the population that have a temperature much lower, even as low as 93°F.

Is It Permanent?

Most doctors are trained to think that if you have a slow metabolism due to a thyroid gland problem, then you're going to need thyroid medicine for life. But the slow metabolism caused by Wilson's Temperature Syndrome is reversible. It’s possible for people to get their metabolism (or temperature) back up and maintain it after two or three months. That can be achieved in several ways:

  1. T3 Hormone Therapy (as opposed to T4 therapy or T4/T3 therapy) 

  2. Increase the variety of plants/herbs in your diet. We don't get a broad spectrum of plants like our ancestors used to. There are certain herbs that have nutrients like selenium and zinc that help increase your body temperature. With the help and guidance of a doctor you can take a certain dosage for a week, and increase incrementally if your temperature remains low. 

  3. Try Fastercise. One of the functions of the thyroid hormone is to increase the size, number, and power of mitochondria. People whose thyroid hormone levels are normal can still experience low body temperature because they don’t have as many mitochondria and they’re not as strong. Fastercise specifically targets the mitochondria because by getting winded at least once a day, the number and size of your mitochondria will increase.

Thyroid Hormones and Misconceptions:

Thyroid hormones are important because they determine, and are necessary to generate your body’s metabolic rate. Your brain regulates your metabolic rate and sends signals through the pituitary gland to the thyroid gland that more thyroid hormones need to be produced.

The general consensus among most doctors is that if you have a problem with your thyroid, the best way to fix it is to prescribe T4, a thyroid hormone. This solution works great for people with a normal body temperature. However, if you have a low body temperature, it’s more effective to use T3.

Why Doctors Shouldn’t Prescribe T4:

The body makes a hormone in the thyroid called T4, which eventually is converted into T3. Most doctors prescribe T4 to their patients with struggling thyroid function in hopes that the body will convert more T4 into T3. But what doctor’s fail to realize is that some patients are not deficient in T4, rather their bodies are struggling in the conversion process. Too much T4 can cause problems because it will suppress the enzyme that facilitates the conversion.

T3 Therapy:

The opposite approach, T3 therapy, bypasses the conversion process altogether by giving patients T3 directly. The other half of the process helps to regulate the amount of T4 to a normal level. This is done by cutting back on T4 medicine or just letting the body regulate itself and increase the production of T4 as more T3 is introduced.

What’s the Difference Between Hypothyroidism and Wilson’s Temperature Syndrome?

The symptoms of hypothyroidism and Wilson's Temperature Syndrome are often the same because they both cause a low body temperature and slow metabolism. The primary difference between them is that hypothyroidism is a thyroid gland dysfunction that affects 3% of the people that have low body temperature. Hypothyroidism is found using blood tests because results will come back abnormal. However, people with Wilson’s Temperature Syndrome will return normal blood tests yet still have a low body temperature. 30% of the population have Wilson’s Temperature Syndrome.
