Symptoms, conditions and causes

What are the reasons for cold intolerance?

A sensitivity to cold temperatures can make simple things stressful--like sitting under the air conditioner at your favorite restaurant. If you find yourself bringing a jacket with you everywhere you go—even in warm weather— follow the below instructions.

Cause #1: Hypothyroidism

Your thyroid helps regulate your body temperature. If you are deficient in certain nutrients, you can develop hypothyroidism--which is reduced thyroid function. This can cause intolerance to cold.


  • Consume sea kelp (has iodine)

  • Consume selenium

  • Consume zinc

  • Consume shellfish

Cause #2: Anemia

Anemia means low body iron, and potentially low B12. Iron is a vital mineral that the body needs for growth and development. People that have anemia are cold and have intolerance to cold.


  • Consume iron-rich foods:

    • red meat

    • cashews

    • for more remedies see chapter on anemia

  • Consume vitamin B12-rich foods:

• meat

• fish

• cheese

• eggs

Cause #3: Insulin resistance

Insulin resistance is a situation where your cells become resistant to insulin, causing
your pancreas to produce more of it. This resistance comes from eating carbs/sugar. Insulin resistance can increase your sensitivity to cold temperatures. (If you are doing intermittent fasting and a keto diet and feel cold, this means that you are not fat-adapted yet; transition can take up to 3 months, but doesn’t have to be that long.)


  • Avoid consuming refined carbs and sugar

  • Avoid snacking

  • Do an intermittent fasting plan

  • Do the Healthy Keto® diet

  • Consume chromium

Cause #4: Deficiency in B vitamins

Vitamins B1, B2, B3, B5 and B6 are vital to the generation of energy by your body. Without these nutrients, you can become sensitive to cold temperatures and your metabolism will be decreased.


  • Consume nutritional yeast

  • Consume B vitamins

Cause #5: Raynaud’s syndrome

Raynaud’s syndrome is a condition in which your fingers and toes turn blue when exposed to cold temperatures due to narrowed blood vessels. B vitamins are a good remedy to resolve this condition.


Consume vitamin B1:

• nutritional yeast • benfotiamine

Consume vitamin B3: inositol hexanicotinate
