Warm clothing is crucial in nursing care for several reasons. Primarily, it helps in thermoregulation, which is the body's ability to maintain its core internal temperature. Patients, especially the elderly and those with compromised health, are often more susceptible to changes in temperature. Proper warm clothing helps prevent hypothermia and other cold-related conditions that can complicate recovery. Additionally, warm clothing provides comfort, which can positively impact a patient's psychological well-being.
