Sources and limitations
People take advice about mental health to heart, especially during hard times. That is why we rely on a small number of reliable sources, cite only verified figures and are honest about the limits of this guide.
A guide can explain how help works. Only a specialist who sees and hears a particular person can actually help them.
What we rely on
Our foundation is materials from the World Health Organization: the guidelines on physical activity and sedentary behavior published in 2020, and the fact sheet on depression.
On sleep duration, we follow the joint recommendation of the American Academy of Sleep Medicine and the Sleep Research Society, published in 2015.
Everything else we describe in general terms, without numbers and without references to individual studies that are hard for readers to check.
Which sources can usually be trusted
- International and national health organizations
- Professional medical associations
- Your own doctor, who knows your health history
- Materials that show who the author is, what they rely on and when the text was last updated
How to check advice about mental health
Who is saying it
Does the author have relevant training, and is it stated? An anonymous text or someone else's personal experience is no reason to change treatment.
What is being sold alongside
If the advice ends with an offer to buy a course, a challenge program or a consultation, evaluate it especially carefully.
Does it match the recommendations
Compare the advice with the WHO's position and your doctor's opinion. A mismatch is a reason to ask a question, not to act right away.
Are there promises of a miracle
Quick, guaranteed changes in the mind do not happen. A promise to change yourself forever in a week is a warning sign.
What this guide does not contain
We do not diagnose, do not publish scored tests, do not name medicines and do not offer techniques for treating yourself. We do not name specific clinics, specialists or apps, and we are not affiliated with the previous website on this domain.

Recommendations are refined over time, so questions about your own health are best discussed with a doctor.
