Health has a variety of definitions, which have been used for different purposes over time.

Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, 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.

Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not, and is defined descriptively by the capacity for homeostasis, organisation, metabolism, growth, adaptation, response to stimuli, and reproduction.

Many philosophical definitions of living systems have been proposed, such as self-organizing systems.

Viruses in particular make definition difficult as they replicate only in host cells.

Life exists all over the Earth in air, water, and soil, with many ecosystems forming the biosphere.

Some of these are harsh environments occupied only by extremophiles.

Information is an abstract concept that refers to that which has the power to inform.

At the most fundamental level, information pertains to the interpretation (perhaps formally) of that which may be sensed, or their abstractions.

Any natural process that is not completely random and any observable pattern in any medium can be said to convey some amount of information.

Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analogue signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form.

Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation.

Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, or cure of disease, illness, injury, and other physical and mental impairments in people.

Health care is delivered by health professionals and allied health fields.

Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care.

The term includes work done in providing primary care, , and tertiary care, as well as in public health.

A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic.

A systematic review extracts and interprets data from published studies on the topic, then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based conclusion.

For example, a systematic review of randomized controlled trials is a way of summarizing and implementing evidence-based medicine.
