Baseline
A starting observation used to compare later changes. It is not a judgment of whether a person is healthy.
A plain-language reference for common terms in Willow articles.
Health writing is full of words that sound familiar but carry different meanings depending on who uses them. A phrase such as "recovery" can describe a night of sleep, a rest day between training sessions or a longer period after illness. When an article uses a word loosely, readers may fill the gap with their own assumptions and arrive at conclusions the writer never intended.
This glossary records how Willow uses its most common terms. The definitions are short on purpose, and they describe everyday meaning rather than a clinical or legal standard. If a word appears in a conversation with a doctor, physiotherapist, dietitian or psychologist, the professional's explanation for your situation takes precedence over anything written here.
The entries are grouped into two panels below. The first covers concepts that come up in almost every article. The second covers practical terms that appear in our guides and checklists. After the panels, a comparison table separates a few pairs of words that are often confused, and a short section explains how to ask for a term to be added.
These six terms provide the vocabulary for most of the library.
A starting observation used to compare later changes. It is not a judgment of whether a person is healthy.
The amount of physical, mental or emotional demand a person can manage in a particular context.
The process of returning toward readiness after effort, stress, illness or insufficient rest.
A gradual increase in challenge, complexity or consistency that respects technique and recovery.
A flexible description for foods close to their original form; it is not a moral category.
Environmental and behavioural conditions that may support sleep, while not replacing assessment of sleep disorders.
The second panel gathers words that appear in guides, checklists and note-taking resources.
A short, periodic reflection on energy, mood, appetite, movement and sleep. It can be shared with a health professional to make a conversation more specific.
The comfortable range of movement at a joint, supported by gentle stretching, strength and regular changes of position during the day.
How consistent bedtime and waking time are across the week. It is often discussed alongside the total hours of sleep.
A common way to describe a meal that combines vegetables, protein, whole-food carbohydrates and unsaturated fats in sensible proportions.
How hard an activity feels to the person doing it, often described on a simple scale. It helps adjust intensity without special equipment.
A clear, calm statement about what you can offer in terms of time, energy or attention. It is a practical tool, not a barrier against people.
A symptom or pattern, such as chest pressure or sudden severe pain, that calls for prompt medical attention rather than self-observation.
A study that independent experts in the field examined before publication. It is a useful signal, although a single study rarely settles a question.
Some pairs of words sound interchangeable but point to different ideas. The table shows how we distinguish them in our writing.
| Term | Often confused with | How Willow uses it | Why the difference matters |
|---|---|---|---|
| Rest | Recovery | Rest is an activity pause; recovery is the wider process of readiness returning | A rest day alone may not restore energy if sleep or food is also short |
| Exercise | Movement | Exercise is planned effort; movement includes walking, chores and play | Both count, and focusing only on exercise can hide everyday activity |
| Symptom | Diagnosis | A symptom is what you notice; a diagnosis is a professional conclusion | Noticing a pattern is useful, but only a clinician can interpret it |
| Habit | Routine | A habit is automatic; a routine is a planned sequence | Routines can be adjusted to life, while habits take time to form |
| Stress | Anxiety | Stress is a response to demand; anxiety can persist without a clear demand | Persistent anxiety deserves a conversation with a qualified provider |
| Source | Opinion | A source is traceable evidence; an opinion is an interpretation | Readers can check a source, but an opinion needs context |
Definitions can make a conversation easier, but they cannot capture every person's experience. If a term appears in a clinical conversation, ask the professional what it means in your specific context.
A helpful habit is to write down any unfamiliar word you meet during an appointment, then look it up afterwards in a reliable source. Public health agencies, professional associations and university health services usually publish plain-language explanations that are suitable for general readers.
A good definition does not close a conversation. It gives two people the same starting point, so that a disagreement or a question can be about the subject itself and not about what a word was supposed to mean.
From the Willow editorial desk
The glossary grows with the library. When a reader tells us that a word felt unclear in an article, the editors check whether a definition would help and, if so, draft one in plain language. Each new entry is reviewed against public health sources before it is published.
For related reading, see the principles that guide our wording and the resources page for ways to check a claim.
Definitions on this page are general information. They do not diagnose any condition and they are not a substitute for professional guidance. If a symptom concerns you, contact a qualified health provider or local emergency services.
