We're only halfway through October, so it's a stretch that anybody has already heard Christmas music while shopping. But it's going to happen and soon.

Linda Blair, not the one from "The Exorcist", is a clinical psychologist and she says that early Christmas music doesn't get you into the holiday spirit. The holly, jolly tunes are actually making you insane.

"It might make us feel that we're trapped," Linda told Sky News. "It's a reminder that we have to buy presents, cater for people, organize celebrations."

The constant reminder of all the stress that comes with the holiday season really takes a toll on your mental health. Every trip to the store just adds more strain to your brain and your wallet. "Some people will react to that by making impulse purchases," she continues. "which the retailer likes."

It's not just the mental health of shoppers at risk either. People who work at stores that play Christmas music all day everyday get hit really bad. The catchy melodies from the songs makes it harder for them to focus on anything else.
