Glossary

Words worth defining

Clear language helps readers make better distinctions when exploring health information. This glossary collects terms that appear across Kleven’s articles, defined the same way everywhere they are used. Each definition on this page includes:

  • A plain-language definition in one or two sentences.
  • A note on how the term differs from everyday usage, when relevant.
  • A link to the article where the term is used in context, where available.

Recovery

The process of returning toward a steady physical and mental state after effort, stress, illness, or insufficient rest. Recovery is not the absence of activity; it is the body’s return to balance afterward.

Preventive care

Appointments, screening, vaccination, and habits intended to identify or reduce health risks before a problem becomes urgent. It is distinct from treatment, which responds to a problem already present.

Evidence

Information used to support a conclusion, including research, clinical experience, and the limits around what has been studied. Strong evidence still has boundaries worth naming.

Strength

The ability to produce force for a task. It can be developed in many settings and through many methods, and is not the same thing as appearance or body size.

Stress response

A set of physical and psychological changes that help a person respond to demand, with effects that may become difficult to manage when the demand is prolonged without recovery.

Shared decision-making

A conversation in which a person and a qualified professional consider evidence, preferences, risks, and practical circumstances together before choosing a course of action.

How to use this glossary

Most readers arrive here from a specific article rather than browsing from the start. These steps help the definitions stay useful either way.

  1. Look up a term the first time you see it underlined or unfamiliar in an article.
  2. Read the short definition, then return to the article with that context.
  3. If a definition raises a new question, check whether a related term on this page answers it.
  4. Bring any remaining question to a qualified professional rather than guessing from definitions alone.

Related term families

Some terms cluster naturally around a theme. This table groups them so readers can explore a category rather than a single word.

Questions about this glossary

Why are definitions kept so short?

A short definition is easier to remember and less likely to drift from the plain meaning intended. Longer context belongs in the article where the term is used.

Can a term mean something different elsewhere?

Yes. Some terms have specialist meanings in clinical settings that are narrower than the everyday definition used here. When that distinction matters, the related article notes it.

Will new terms be added?

Yes, gradually, whenever a new article introduces a word that is not already plain English.

A note on precision

“A glossary is not a shortcut around understanding. It is a way to stop understanding from being blocked by a single unfamiliar word.”

Readers are encouraged to treat each definition as a starting point, not a complete account of a term that specialists may discuss at far greater length.
