It is generally recognized that a number of undesirable conditions in the head and neck can be corrected or improved by stimulating circulation in the affected area. Some of the many techniques developed under the general heading of physical therapy have this as a primary objective. Congestion in the nasal and sinus areas, and occasionally around the ear structure, will frequently respond to this form of treatment. The functioning of the brain itself is highly responsive to the slightest interruptions or reductions in circulation, and this becomes particularly acute in cases involving arteriosclerotic conditions. It is common experience of almost everyone that spells of dizziness or other mental misfunctioning can frequently be relieved by lying down with the head somewhat lower than the rest of the body.
