The Myth of ‘Blue Monday’ as the Most Depressing Day Explained

What happened: The idea that the third Monday of January is the most depressing day of the year has been debunked. The concept originated from a marketing campaign rather than scientific evidence.

Why it matters:

  • It helps people understand that feelings of low mood are not confined to a single day.
  • It prevents the spread of misleading information about mental health and seasonal mood changes.

MNN Take: ‘Blue Monday’ is a marketing invention without scientific basis, reminding us to approach mental health topics with care and rely on evidence-based information.
