Microclimate



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
  • Reduces stiffness, softens skin, may cause maceration
  • May reduce strength of skin by up to 96% and may lead to erosion
  • Increase the co-efficient of friction
  • Increases adhesion to contact surface and may increase the risk of shear
  • Promote abrasion, slough and ulceration
  • Shifts skin pH from acidic to alkaline
  • Elevated temperature increases metabolic rate
  • Elevated temperature leads to increased sweating
  • At the interface point with the support surface, body heat becomes trapped, the skin's temperature increases, and moisture accumulatesAnimal studies have demonstrated a link between higher temperatures and ulcer formation14
