Why ‘Blue Monday’ might not be as bleak as you think
The third Monday in January is often referred to as Blue Monday—the supposed gloomiest day of the year. British psychologist Cliff Arnall first introduced the term in 2005 as part of a travel company’s marketing push. His formula factored in poor weather, post-holiday debt, and the return to daily routines after festive celebrations.
Arnall’s concept was never scientifically proven but gained widespread attention. He claimed the date—falling in mid-January—marked a slump caused by short daylight, financial strain, and fading holiday cheer. The combination of cold weather, lingering Christmas bills, and the end of festive breaks contributed to the idea of a collective low mood.
Despite its origins in advertising, the notion of Blue Monday has persisted. Psychologists, however, suggest practical ways to counter seasonal sadness. Regular sleep, a balanced diet, exercise, and outdoor walks can help lift spirits. Socialising, spending time with pets, and listening to music are also recommended for improving mental well-being. Contrastingly, the Northern Hemisphere’s happiest day is said to be June 20—the summer solstice. With maximum sunlight and longer days, it offers a natural mood boost compared to the darker winter months.
Blue Monday remains a cultural talking point rather than a clinical diagnosis. While its scientific basis is weak, the mid-January slump highlights real seasonal challenges. For those feeling low, small lifestyle changes may offer relief until brighter days return.
