Anti-aging medicine is an evolving branch of medical science and applied medicine. It treats the underlying causes of aging and aims at alleviating any age related ailment. Its goal is to extend the healthy lifespan of humans having youthful characteristics. There are three main strategies to reach these results: homeostasis regulation, removing accumulated age-specific damages and errors, improving system reliability.
Although the descriptive data about aging suggest that there are no universal markers of aging, some general principles can still be derived, which can be useful for future research and intervention. These are: (1) aging is considered to be an emergent phenomenon seen primarily in protected environments which allow survival beyond the natural lifespan in the wild. This is because most animals in the wild die due to accidents, infections, and predation without showing significant signs of aging; (2) aging is the progressive failure of homeodynamics (or homeostasis), which is the ability of all living systems to respond to internal and external stress, and to counteract by neutralization and/or by adaptation any disturbances threatening their survival. A failure of homeodynamics leads to the impairment in functional ability at all levels of organization and increased possibilities of a plethora of diseases and eventual death; (3) unlike development, which is a highly programmed and well-coordinated genetic process in the evolutionary life history of an organism, there is no genetic program which determines the exact duration of survival of an organism.
One of the anti-aging strategy, performed by Balvant P. Arora, consists of further principles: enhance health through eating a hormonally correct diet, enrich body with optimum doses of proven antioxidants and nutraceuticals, improve physical exercise performance, which includes aerobic, anaerobic and flexibility training, replace hormones to levels to those of 20-30 years old.
Hormesis is a term describing the beneficial effects of mild and repeated stimulation or stress, which ultimately bolsters defences against deleterious processes. So one of the anti-aging strategy is to activate hormetic pathways without stress-induced damages.
