Importance of Good Blood Circulation
Of all the various functions of the human body the circu¬lation of the blood is perhaps the most vital. Coldness of the surface always indicates recession of the blood to internal organs; so the greater the surface affected and the degree of coldness, the more serious the condition thus manifested is likely to be. A hot head and cold hands indicate brain con-of gestion. A hot abdomen and cold feet indicate intestinal con- gestion. Heat over the chest or upper portion of the back coincident with cold extremities denotes lung trouble.
A cold nose often signifies intestinal torpidity. One cheek hot and the other cool shows nervous fever, or sometimes pneumonia. Both cheeks flushed may show hectic fever. As our health depends upon the equalization and purity of the blood stream, the first step toward relief is the equalization of the circula¬tion and the free functioning of the secretions and excretions.
In every case of disturbance of health the predisposing causes must be considered, for if the blood is pure and the organism has sufficient vitality no disease is likely to develop. A sore throat will arise only when there is a lack of resistance, or when there are accumulated wastes. Such a condition as cold, wet feet may be regarded as the immediate cause, though the primary causes are of the kind enumerated in detail under Colds.
The temporary chilling of a healthy body or any part of it will have little harmful effect, though prolonged interference with the circulation will be likely to cause trouble.
