ikäitumis

Ikäitumine is the Estonian word for aging. It refers to the biological process of growing old, which is characterized by a gradual decline in physiological function and an increased susceptibility to disease and death. This process is influenced by a complex interplay of genetic, environmental, and lifestyle factors.

In biological terms, aging involves cellular damage accumulation, such as DNA mutations and oxidative stress. Over time, these damages can impair cell function and repair mechanisms, leading to a loss of tissue and organ integrity. Hormonal changes also play a significant role, with reductions in certain hormones like growth hormone and sex hormones contributing to age-related physical and cognitive changes.

From a social and psychological perspective, ikäitumine encompasses the various ways individuals experience and adapt to growing older. This includes changes in social roles, relationships, cognitive abilities, and emotional well-being. Societal views and support systems also impact how individuals navigate this life stage.

The study of aging, gerontology, seeks to understand the mechanisms of aging and to promote healthy aging. Research explores interventions that might slow down the aging process or mitigate its negative effects, aiming to improve the quality of life for older adults. While ikäitumine is an inevitable part of life, its impact and experience can vary greatly among individuals and populations.
