How does the skin regulate body temperature
Some factors that contribute to the problem of vulnerable skin could be prevented, such as the use of irritants, stripping by adhesive dressings, occlusion and exposure to infection or allergens. Thinning of the epidermis is caused by a reduction in the number of cell layers; sometimes atrophy is very pronounced and scars or pseudo scars herald tears in the skin layers. Healthcare professionals should be aware of the problems that vulnerable skin may cause in patients with wounds. References 1. Skin Pharmacol Physiol ; 19 6 : This thick layer appears only in frequently used areas such as palms of the hands and soles of the feet. This destroys the local barrier function of the skin. Understanding these factors related to life expectancy and preventing their repercussions on the skin are the new missions of dermatologists. Its functions include protection of internal structures, prevention of entry of disease-causing microorganisms, temperature regulation, excretion through perspiration, pigmentary protection against ultraviolet sunrays, and production of vitamin D. No new hair follicles develop after birth. Pronounced atrophy of all layers of skin and subcutaneous tissues may be seen as a consequence of radiation damage.
Maintaining the functional and anatomical integrity of the skin is essential. The cuticle, the outermost layer, has cells that overlap like scales.

This odor differs from body odor that results from bacteria decomposing skin secretions on the skin. Infection is a cause of acute and chronic inflammatory reactions, and patients with lymphoedema in particular may suffer from recurrent bouts of cellulitis. Hair has a protective function: eyebrows keep sweat from running into the eyes, nose and ear hairs filter dust from the air, and scalp hairs protect against abrasion and overexposure to sun rays. In such patients, extreme vulnerability and susceptibility to mechanical trauma may render dressing changes very challenging. Folic acid, vitamin D, calcium, and vitamin B12 deficiencies are prevalent, 49 and they tend to increase with age, particularly when reduced absorption or decreased ingestion occurs. The skin provides protection from: mechanical impacts and pressure, variations in temperature, micro-organisms, radiation and chemicals. The pH can rise significantly under occlusive dressings and on exposure to skin irritants such as ammonia and stool enzymes in nappies or continence pads, resulting in disruption of the skin barrier and irritation . These include the quality of the epidermal cells, of the interaction between cells, of the epidermis and dermis, of the intercellular substances, and of the immune system.
Moist body folds, the axillae, genito-anal region and the interdigital spaces have a slightly more alkaline pH and are more prone to yeast and fungal infections. Eccrine glands secrete sweat, a mixture of 99 percent water and 1 percent salts and fats.
Integrin heterodimers containing CD29 mediate cell-to-cell and cell-to-matrix adhesion, and are also involved in a variety of processes including embryogenesis, tissue repair and development.
This communication provokes certain behavioral responses such as sexual arousal.
