What Physical Changes Occur During Early Adulthood?
Early adulthood, a period typically defined as being between the ages of 25 and 40, brings with it a whole host of physical changes, including changes in the reproductive system, skin, hearing and vision, according to Boundless. As the body ages during this period, immune function is also decreased, giving way to sickness and disease in some individuals.
Around the age of 30, changes related to aging start to occur in the body, according to Boundless. Vision is one of the significant changes, as during this time the lens of the eye begins to thicken and harden, resulting in a decreased ability to view objects close-up. Sound sensitivity also commonly decreases around this period, occurring twice as fast in men as in women. During this age range, the skin begins to dry out and wrinkles start to form. Reproductive function also begins to decline towards the end of early adulthood.
Aging is comprised of primary and secondary aging, according to Boundless. Primary aging refers to changes that occur on a molecular and cellular level within the body; these type of changes are an unavoidable part of aging. Secondary aging is aging that occurs due to lack of exercise or poor nutrition.
