What this content is, what it is not, and when to see a doctor instead.

This is education, not medical advice

Everything here is general information drawn from published research. It is not a diagnosis, not a treatment plan, and not advice about you — it cannot know your history, your medication or your circumstances, and those are usually what decide the right answer. Reading this site or watching the videos does not create a doctor–patient relationship.If you have a health concern, ask a doctor or another qualified healthcare professional.

If something is urgent, stop and get help

Nothing here is meant for urgent situations. Call your local emergency number —112 in Germany and the EU, 999 in the UK, 911 in the US and Canada — for anything sudden or severe, such as chest pain, difficulty breathing, weakness or numbness on one side, trouble speaking, or a sudden severe headache.

If you are having thoughts of harming yourself, please contact a crisis line now. In Germany, Telefonseelsorge is free and answers day and night on 0800 111 0 111.

Never change prescribed treatment because of something here

Do not start, stop or alter any medication or therapy on the basis of this content, and do not use it to delay seeking care. If something here seems relevant to your treatment, raise it with the person treating you. Stopping some medication abruptly — or stopping regular heavy drinking abruptly — can be dangerous in itself and needs medical supervision.

What the evidence can and cannot tell you

These are averages across groups of people. A pooled result describes what happened in a study population. It does not predict what will happen to you, and you may differ from that average in ways that matter.
An association is not a cause. Where the underlying research is observational we say "linked to" rather than "causes", and we mean the distinction literally — something else may explain the link.
The measured outcome is the whole claim. A change in a blood-pressure reading, a blood-sugar response or a pain score is not a demonstration that a disease was prevented, treated or cured.
Evidence changes, and we correct in public. See Corrections.

Some topics unavoidably concern people who already have a symptom. Those are scoped to what the research measured, in the population it studied. That is still not treatment and never a substitute for diagnosis — anything new, severe, persistent or worsening needs a professional opinion rather than a behaviour change.

Nothing here is sold or recommended

Every fix published here is a free change in behaviour. There are no ads, no sponsorships, no affiliate links and no products, and no supplement, device, treatment or practitioner is recommended anywhere on this site.

How this is made

The videos use a synthetic voice and are produced with AI assistance. Every factual claim is checked against the primary source by a named human being before publication, and each one is shown with its author, year, journal and DOI so you can read the source yourself. The full process is on Method.

We take real care over accuracy, but cannot promise this content is complete, current, or right for your situation. Decisions about your health belong to you and your healthcare professional.

If you think something here is wrong, please say so. Corrections sets out how to report it and what happens next, and every correction we make is published there in the open.
