Cold hands and cold feet are very common in modern people. This symptom can often occur during sleep because of reduced oxygen levels in body cells. Cold feet and cold hands are a sign of poor circulation which leads to reduced oxygen supply to body cells.
What is the main physiological meaning of cold feet and hands? Cold extremities are a classical symptom of chronic hyperventilation. While the official diagnoses can be Raynaud disease or diabetes, in reality, all these people suffer from too heavy breathing.
All vital organs of the human body and extremities get reduced blood and oxygen supply. Most people get only cold feet and there are also millions of people who suffer from cold hands as well.
If you normalize your automatic or unconscious breathing patterns, your chronic problems with signs of poor circulation and cold hands and feet will naturally disappear.
