Cold Hands and Feet Causes: Causes, Symptoms and Meaning
Cold hands and feet are very common in modern people for the reasons that are explained below. This symptom can often occur during night-time sleep for a very simple reason: people have reduced O2 levels in body cells. What is the meaning of this symptom? Cold feet and hands are a sign of insufficient blood flow (poor circulation) and reduced oxygen supply to body cells and their cold extremities.
Cold feet due to parasites
Warning. Cold feet can be caused by presence of GI parasites, such as flat worms, round warms and some others.
Meaning of cold hands and feet
What is the main physiological meaning of cold feet and hands? In his article, "Hyperventilation and anxiety state" that was published in the Journal of Royal Society of Medicine, Professor Lum stated that cold extremities are a classical symptom of chronic hyperventilation or breathing more than the medical norm. Cold feet and hands mean that the person has less than 20 s for the body-oxygen test. While the official diagnoses can be Raynaud disease or diabetes, in reality, all these people have too heavy breathing 24/7.
This graph is based on 24 medical articles. It explains why problems with poor circulation and cold hands and feet are very common in modern people, and why cold extremities were not common during first decades of 20th century.
Symptoms related to cold feet and hands
Hyperventilation reduces CO2 in the lungs. This causes lowered arterial CO2 pressure resulting in constriction of arteries and arterioles since CO2 is the most potent vasodilator (see studies below). In addition, low CO2 leads to the reduced Bohr effect (less O2 is released in tissues by red blood cells). As a result, people suffer from having cold extremities.
All vital organs of the human body and extremities get reduced blood and O2 supply. Most people get only cold feet. But there are also millions of people who suffer from cold hands as well.
If you try voluntary hyperventilation, in 1 minute your brain oxygen levels will be about two times less and, in 2-3 minutes, most people can faint due to critically low brain-O2 content.
Natural remedies for cold feet and hands
You can use a simple breathing exercise developed by over 170 Russian doctors who taught the Buteyko breathing technique to thousands of their patients with cold hands and feet. This exercise can be found here: Warm up cold hands and feet. According to reports of these doctors, over 80% of people are able to get warm hands and feet in 2-3 minutes.
An additional powerful method that helps with body O2 and circulation is Earthing since getting electrons from the Earth helps blood vessels and decreases inflammation. A sea salt bath for cold feet can be found on this page How to ground yourself. It is a great solution to normalize voltage of the human body and improve circulation. Earthing also increases body-oxygen content.
Permanent solution for cold feet and cold extremities
If you normalize your automatic or unconscious breathing patterns (so that your body O2 will be over 40 seconds all the time), your chronic problems with signs of poor circulation and cold hands and feet will naturally disappear.
In fact, for most people, it is enough to get over 25 seconds for the body-oxygen test in order to improve their poor circulation. Furthermore, people with sleeping problems can also eliminate their insomnia at night using the same breathing exercise and breath retraining.
Very cold feet can be caused by worms and other GI parasites (such as Blastocystis Hominis). Contact your MD or GP for lab tests and treatment options.
