Why Do We Love the Smell of Christmas Trees?

Christmas trees are more than just decorations. They are a big part of the holiday season for many families. But have you ever wondered why we love them so much? Scientists are trying to figure that out.

A Major Study Underway

A big study is happening right now. It's all about what makes Christmas trees so appealing. The study is funded by the U.S. Department of Agriculture. It's a $7.4 million project. The goal is to breed better fir trees.

The Power of Scent

One of the main things people love about real Christmas trees is their smell. Scientists are studying this. They did tests with different types of fir trees. People smelled branches and rated how strong the aroma was. They also described what they smelled, like piney or citrusy notes.

The Role of Terpenes

The smell comes from something called terpenes. These are compounds in plants that give them their distinct smell. Different fir trees have different terpenes. The study wants to find out which terpenes people like the most.

Importance of the Research

This research is important. It can help tree growers. They can grow trees that people will love. It's a balance. Growers need to meet what people want. And people want trees that smell great and look good.

The Team Behind the Study

The study is led by Justin Whitehall. He is an assistant professor at North Carolina State University. But many other scientists are involved too. Like Carolyn Ross from Washington State University. She is a professor of food science. And Gary Chastagner, known as "Dr. Christmas Tree."

Beyond the Smell

The study is not just about smell. It's also about other things. Like how well the trees keep their needles. And how they look on display. All these things matter to people when they pick a tree.

The Ultimate Goal

In the end, this research is about making people happier. It's about giving them the perfect Christmas tree. The one that smells amazing and looks beautiful. That's what the holiday season is all about.
