Have you ever been outside, taking in the sights and sounds of nature, and felt like all of your worries suddenly disappeared? You're not alone in this feeling, as it turns out. In fact, a recent study, carried out by a team of researchers from Colorado State University, Carleton University, Michigan State University and the National Park Service proved that humans really do become less stressed when outdoors, among nature.

More specifically, the team of scientists learned that listening to the sounds of nature hugely benefits humans' health.

In order to reach their conclusion, researchers gathered sound recordings from 251 sites in 66 national parks across the United States. These recordings of natural sounds, including birds chirping and creeks flowing, were then played for a selection of people, while the scientists studied how the noises impacted their health.

After playing the sounds of national parks to the panel involved in the study, the team discovered that people experienced decreased pain, lower stress, improved mood and enhanced cognitive performance.

The study showed that the sounds of water had the greatest impact on improving positive emotions and health outcomes. Fortunately for us, there are plenty of places to relax and sit by the water in Northern Colorado, including gorgeous waterfalls in Rocky Mountain National Park.

Scientists also found that bird sounds can help to combat stress and annoyance.

Next time you're out in nature, CSU researchers suggest closing your eyes and really being mindful of the sounds that surround you. Not only are they beautiful, but it's also good for your health.
