What’s the latest major finding from the science world? Every time you hear a Christmas song like “Frosty the Snowman,” you like it less and less.

Researchers recently studied the effects Christmas songs have on our brain. And they discovered the songs trigger a psychological condition called the “mere exposure effect.”  At first, your brain enjoys holiday music.  But over time, it becomes overkill. Like “This is the 30th time today I’ve heard ‘Feliz Navidad’” – and your brain interprets the formerly jolly sounds as just plain old annoying.

Another new scientific finding about Christmas music? It’s extremely polarizing and whether or not you love it or hate it depends on your psychological state.

Dr. Victoria Williamson researches the psychology of music – and she says that if you’re stressed about the holidays with bills, traveling, or family then, hearing “Rudolph the Red Nosed Reindeer” subconsciously reminds you about holiday stress so you automatically associate Christmas songs with stress.

But if you have a relaxed approach to the holidays, then you’re more likely to get a pick-me-up from hearing Christmas songs because of all the positive associations they remind you of – like childhood memories, and family.
