There are whole areas of philosophical study that delve into the nature of art and beauty. Philosophers believe learning what a certain group or culture finds aesthetically pleasing can help us better understand what they value, how they interact with each other, and make decisions.

Consequently, they are interested in learning more about the relation between aesthetic appreciation and our emotional response. In this way, understanding how the brain processes what we see, and how our aesthetic impressions are formed, is also of interest to cognitive psychologists.

Therefore, both philosophers and psychologists acknowledge that our aesthetic perceptions of the world around us affect our emotions. And, when the environment around us is perceived as beautiful and aesthetically pleasing, our emotions are affected in a positive way.

That is proof enough for me to create a beautiful environment to live in and seek out experiences that allow me to appreciate something beautiful as often as possible.
