If you think some people start playing Christmas music "too early"... you could be right.
Experts have confirmed that being exposed to so much seasonal joy can be detrimental to your health.
Clinical psychologist Linda Blair told Sky News:
"People working in the shops at Christmas 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."
Basically, TOO MUCH holiday music can put you in a bad mood.
