January 19 is popularly referred to as the saddest day of the year, also known as Blue Monday. While there is no scientific evidence to prove that this particular day is sadder than others, it can still be challenging for many people.
Coined by psychologist Cliff Arnall in 2005, the term "Blue Monday" has a specific background. It was originally proposed for the UK travel company Sky Travel as part of a campaign to promote winter holidays.
The idea behind choosing the third Monday of the year was based on a formula that combined factors such as weather conditions, levels of debt, time elapsed since Christmas, motivation levels, and the period since New Year’s resolutions were made.
Many people experience this day as a short-term seasonal dip in mood and energy, often linked to the coldest and darkest period of the year. Others describe it as one of the saddest days due to several factors, including the distance from Christmas, rising debt levels, and the tendency to abandon New Year’s resolutions.
Blue Monday is often associated with Seasonal Affective Disorder (SAD), a type of depression linked to seasonal changes. During winter, people may feel less cheerful and more lethargic, a condition commonly driven by longer dark hours, harsh weather, and fewer outdoor activities.
These symptoms usually begin in late autumn and fade as sunnier days return in spring. Individuals suffering from SAD often experience persistent low moods, difficulty concentrating and sleeping, and a loss of interest in activities they once enjoyed.
Although the exact cause of SAD remains unknown, experts link it to reduced exposure to sunlight, which can affect natural chemicals in the body such as serotonin and melatonin, both of which regulate mood and energy levels.
A person experiencing low mood on Blue Monday can manage it by practising self-care. Here are some helpful steps:
Engage in regular exercise
Get exposure to sunlight
Maintain a good sleep routine
Connect with family and friends
Surround yourself with positivity
Manage stress levels effectively
Seek counselling or talking therapies
Use antidepressant medication, if prescribed by a professional
