Overview
- Psychologist Cliff Arnall’s 2005 formula for Sky Travel is widely dismissed as pseudoscience, with no evidence that the third Monday in January is uniquely depressing.
- Mind and Samaritans warn the label trivialises depression, with Samaritans calling it “a load of rubbish” and promoting Brew Monday to encourage conversations and help‑seeking any day of the year.
- Clinicians emphasize that winter low mood and Seasonal Affective Disorder are real conditions linked to reduced daylight and circadian disruption, and they recommend light exposure, exercise, CBT, light therapy, and seeking professional care when symptoms persist.
- Researchers caution that the media narrative can become a self‑fulfilling expectation and note the commercial roots of the day, which can also drive unhelpful spending tied to low mood.
- Jan 19–20 coverage across the UK, Canada, India and local outlets highlights debunking efforts and points audiences toward practical resources, from NHS guidance to community programs targeting the winter blues.
