Senescence refers to the process of biological and psychological changes associated with normal aging. It involves primary and secondary aging factors and is shaped by cultural attitudes towards aging.
The term "senescence" refers to the process of biological changes associated with normal aging. This encompasses a range of changes, both physiological and psychological, that occur as individuals grow older. Senescence includes molecular and cellular changes known as primary aging, as well as changes resulting from lifestyle choices, such as exercise and diet, known as secondary aging.
The concept is broad and covers intellectual, emotional, social, and spiritual aspects of aging. The study of aging and its implications is not limited to physical decline but also considers the social significance and psychological impact of growing older. Factors like immunosenescence contribute to increased susceptibility to diseases among the elderly.
In social gerontology, scholars look at how society's attitudes and beliefs about aging can influence the experience of growing older. Cultural values affect how aging is perceived; for example, cultures valuing youth may make aging seem negative, whereas cultures that revere the elderly may foster a more positive view. It's also essential to distinguish between natural aging and aging that comes prematurely due to health issues or external stressors.
So, senescence is the comprehensive term that encapsulates the age-related transformations that constitute the normal aging process.
