How Climate Modifies Skin Physiology and Wound Healing

Te skin serves as the body 's first barrier against ingistion and injury. Climatic conditions alter its structure and funktion in ways that can either proct or predispose to ulceration. High ambient temperatures increate perspiration, which can soften thee stratum corneum - a process called maceration - making the skin fragile and prone tearing.
