Health

A variety of definitions have been used for different purposes over time.

Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep,^[2] and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress.

Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services.

Still, other factors are beyond both individual and group choices, such as genetic disorders.
