What is a common physiological change that occurs in older adults?

As individuals age, a common physiological change is decreased skin elasticity. This occurs due to a reduction in collagen production and the breakdown of elastin fibers in the skin, leading to a sagging appearance and increased wrinkling. These changes are influenced by both intrinsic factors, such as aging itself, and extrinsic factors, such as sun exposure and lifestyle choices.

In contrast, increased muscle mass tends to be less common in older adults, as many experience a decline in muscle mass and strength—a condition known as sarcopenia. Improved metabolic rate is also generally not observed; instead, older adults typically experience a slower metabolism, which can lead to weight gain if eating patterns remain the same. Lastly, while some aspects of sensory perception may improve, such as familiarity with certain tasks, overall sensory abilities like vision and hearing often decline with age. Therefore, decreased skin elasticity stands out as a significant and recognized physiological change in older adults.
