Genotype as a health factor. The basis of human health is the ability of his body to withstand environmental influences and maintain the relative constancy of homeostasis. Violation of homeostasis for various reasons causes the disease, impaired health. However, the type of homeostasis itself, the mechanisms of its maintenance at all stages of ontogenesis under certain conditions are determined by genes, more precisely, by the individual’s genotype.
Habitat as a health factor. It has long been noted that both heredity and the environment are important in the formation of any trait. Moreover, it is sometimes difficult to determine what this or that sign more depends on. For example, a trait such as growth is inherited using many genes (polygenically), i.e., achieving normal growth characteristic of parents depends on a number of genes that control the level of exposure to hormones, calcium metabolism, the usefulness of digestive enzymes, etc. At the same time, even the “best” genotype regarding growth under poor living conditions (lack of nutrition, sun, air, movement) inevitably leads to a lag in body length.
Social health factors. In contrast to plants and animals, a special area of ontogenesis in a person is the formation of his intellect, moral character, and personality. Here, along with biological and non-biological factors common to all living things, a new powerful environmental factor, the social one, also acts. While the former mainly determine the potential range of the reaction rate, the social environment, upbringing, and lifestyle determine the specific embodiment of the hereditary inclinations of a given individual. The social environment acts as a kind of mechanism for the transfer of the historical experience of mankind, its cultural, scientific and technical achievements.
