WHO-5
A two-minute check-in on how you've actually been feeling — the WHO-5 index.
The WHO-5 Well-Being Index is the World Health Organization's five-question check on how you've been feeling over the past two weeks — cheerful, calm, active, rested, interested. It's used in research and clinics worldwide precisely because it's short and sensitive to change.
Two minutes gets you an instant, private result in plain language. It's the single best test on this site to retake regularly — a monthly WHO-5 is a lightweight early-warning system for your own wellbeing.
Five questions — about 2 minutes. It's designed for regular check-ins.
No — but a persistently low WHO-5 is a well-validated reason to check in with yourself more deeply, or with a professional.
Monthly is a sensible rhythm. Signed in, your results build a trend over time.
