If you’re the sort of person that plays Mariah Carey’s Christmas album from November 1, playing that much festive music can be bad for your brain.
Research has found listening too much to catchy Christmas carols can disrupt a person's focus and generate stress, especially if you're trying to avoid listening.
"It might make us feel that we're trapped - it's a reminder that we have to buy presents, cater for people and organise celebrations," UK Psychologist Linda Blair told Sky News.
Christmas music is also more likely to irritate people if it's played too loudly or too early in the year.
However, if you wonder why retailers seem to sneak in their Christmas playlist as early as possible, it’s because it has positive effects for the retail industry.
Studies have also shown festive music paired with festive scents can actually make shoppers feel happier in a store and are therefore more likely to make purchases.
