Definition - the local tissue temperature and moisture
at the body/support surface interface.

Fast Facts

  • Moisture is known to impact on ability of the skin to function
  • Reduce stiffness - softens skin, maceration
  • Reduce strength - up 96%, lead to erosion
  • Increase co-efficient of friction
  • Increase adhesion to contact surface – increase risk of shear
  • Promote abrasion, slough and ulceration
  • Dilute skin acidity - pH shift to alkalinity
  • Elevated temperature increases metabolic rate
  • Elevated temperature leads to increased sweating
  • At interface point with support surface, body heat becomes trapped causing the skin to rapidly warm - heat accumulates and moisture builds up
  • Animal studies have demonstrated a link between heat build up and ulcer formation14
