During the holiday season, it can be hard to escape Christmas music. Stores play it while you’re holiday shopping and radio stations play it on your way to work or school. Many people love Christmas music, but what if too much of these holiday carols can actually do more harm than good?

According to Business Insider, new studies show that Christmas music could actually be damaging to your mental health. This is a result of the Mere Exposure Effect. This effect states that the over-saturation of anything could lead to excessive amounts of stress and worrying (CBS Philadelphia).

Businesses know this and use it to their advantage. Stores will play Christmas music early to get customers to spend more money. The stress from the music can lead to extravagant and unnecessary purchases.

On the bright side, decorating for Christmas early can be good for your mental health. Decorations bring back good memories of the past without over-saturation (WFNY News).

Americans do tend to listen to Christmas music earlier than most countries. According to Spotify, Christmas music spikes on November 29 and continues to dominate the charts through the holiday season.
