Feeling Cold For No Reason

What Causes Feeling Cold?

Feeling cold can have various causes, ranging in severity from 'worrying' to 'life-threatening'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • understand what's happening to your body
  • identify any nutritional deficiencies
  • learn what you should be doing right now

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose feeling cold, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "feeling cold" as a symptom.  Here are eight of many possibilities (more below):
  • Underconsumption
  • Anemia
  • Chronic Infection
  • Anxiety
  • Seasonal Affective Disorder
  • Adrenal Fatigue
  • Diabetes II
  • Mercury Toxicity

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
poor ability to relax
regular chest tightness
nausea for 1-3 months
occasional unexplained fevers
darker/redder skin color
type 2 diabetes NIDD
lighter/paler skin color
morning sickness
having trouble concentrating
unexplained missed periods
... and more than 150 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of feeling cold:
Cause Probability Status
Diabetes II 92% Confirm
Chronic Infection 25% Unlikely
Adrenal Fatigue 17% Unlikely
Anxiety 1% Ruled out
Underconsumption 0% Ruled out
Anemia 0% Ruled out
Seasonal Affective Disorder 0% Ruled out
Mercury Toxicity 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Metabolic Symptoms section of the questionnaire, The Analyst™ will ask the following question about feeling cold for no reason:
How often do you feel cold for no apparent reason? This question refers to your whole body, not just hands and feet.
Possible responses:
→ Don't know / hands and feet only
→ Never / less than once a year
→ Occasionally - several times a year
→ Regularly - several times a month
→ Often/always
Based on your response to this question, which may indicate not feeling unusually cold, occasionally feeling unusually cold, regularly feeling unusually cold or often/always feeling unusually cold, The Analyst™ will consider possibilities such as:
(Prescription) Drug Side-Effects

Certain medications – such as those prescribed for hypertension, angina, or migraine – can cause feelings of being cold because beta blockers may reduce the circulation in the extremities while increasing blood circulation to the heart.

Anorexia / Starvation Tendency

Underweight people often feel cold due to having less fat and muscle mass.  Body fat acts as insulation to keep the body warm; muscle activity generates heat.

Diabetes Type II

The coldness caused by diabetic hypoglycemia is usually accompanied by weakness and, in severe cases, disorientation and fainting.


As a result of fasting, skipping meals or eating too little, the body will try to conserve energy by producing less body heat, thus reducing your body temperature.

Vitamin B-Complex Requirement

Vitamin B-complex deficiency is known to cause feelings of internal coldness as your core body temperature dips.
