When is Blue Monday?
Blue Monday, often known for being the most depressing day of the year, falls on the third Monday of January. This day was first declared in 2014 by Speaker Cliff Arnall (i). In 2025, this date is the 20th of January.
According to the belief, this time of year is often associated with a peak in respiratory infections, shorter days, gloomy weather, and the lingering guilt of whether people will stick to their New Year’s resolutions.
However, there is a lack of scientific evidence to support that Blue Monday is the most depressing day of the year and is rarely a myth that oversimplifies complex emotional experiences.
Despite its questionable origins, Blue Monday serves as a reminder of the genuine mental health challenges many individuals face during the winter months (ii).
The Relationship between Mental and Oral Health
Mental health has a profound impact on many parts of our lives, including oral health. Individuals who are depressed or anxious may neglect dental hygiene routines, resulting in gum disease, cavities, and tooth loss (iii).
Stress and anxiety often manifest in behaviours detrimental to oral health, such as teeth grinding (bruxism) and jaw clenching. These habits can cause tooth damage, headaches, and jaw pain. Recognising and addressing these behaviours is crucial to prevent long-term oral health issues.
Conversely, poor oral health can exacerbate mental health conditions, creating a cyclical effect.
