The brain can become oversaturated and end up triggering a negative response, leading you to feel the opposite of the Christmas cheer and even worsening some stress you may be feeling related to the season, such as worries over spending money on gifts.
Christmas music can also be distracting and cause a decrease in staff productivity.
"People working in the shops [have to tune out] Christmas music, because if they don't, it really does stop you from being able to focus on anything else ... You're simply spending all of your energy trying not to hear what you're hearing," clinical psychologist Linda Blair says, quoted by Business Insider.
Experts recommend switching up the music from the same old classics to avoid boring the brain.
Good sound management is essential to avoid these adverse reactions.
