Aging: Thermoregulation And The Immune System

Satisfactory Essays
Aging impacts both the thermoregulation and the immune system. The geriatric population has lower body temperatures and dysregulated thermoregulation. It is hypothesized that these mechanisms are effected with aging due to decreased subcutaneous tissue, which mean this tissue cannot perform as an insulator. Vasoconstriction does not work adequately and diminished cardiac output can diminish peripheral blood flow. Fevers in the elderly often present atypically. This indicated that in the elderly population, a fever may not occur at all or will be 20 to 20 percent lower than in a younger individual. If an elderly patient presents with a higher temperature, it may be indicative that the patient has a severe infection and this should be taken quite
