THE EFFECT ON SWEATING OF PRESSURE ON THE BODY SURFACE
1 The Hot Climate Physiological Research Unit, Oshodi, Lagos, Nigeria
1. Simultaneous collections of sweat from both scapular regions of West Africans, using a filter-paper weighing technique, have been made to observe the changes in sweating during the application of pressure to one side of the body.
2. When no pressure was applied, it was found that sweating on the two sides of the body may be changing in opposite directions at any one time.
3. The hemihidrotic response to pressure, described by Takagi and Sakurai [1950] was only occasionally demonstrated, and its validity is suspect in view of the changes in sweating found when no stimulus was applied.
