People over 60 often feel cold more easily, even in a warm home. As the weather gets colder, some in this age group are reaching for sweaters and blankets. This sensitivity to cold is not just in their minds; it is due to several changes that come with aging, such as a slower metabolism, loss of muscle mass, less efficient blood circulation, or certain chronic diseases, according to Dr. Elise Dallas, a general practitioner at the London General Practice. As temperatures drop, the body needs to produce more heat to maintain its internal temperature. However, this process becomes less effective with age. One important factor is the progressive loss of muscle mass, known as sarcopenia. Muscles help generate body heat and act like an "internal radiator." Additionally, the layer of fat under the skin, which helps insulate the body, may also decrease with age. Dr. Elise Dallas explains that several factors combine to affect how the body perceives and responds to cold. "Thinner skin, reduced function of sweat glands, less physical activity, and an impaired hypothalamic response all reduce the body's ability to perceive and respond to cold," she says. "A lower caloric intake and reduced activity of brown fat also contribute to this." These changes can make it more difficult for older adults to stay warm, especially during colder months. Understanding these physiological shifts can help individuals take proactive steps to manage their comfort and health during the colder seasons.
