Interacting with cats and dogs may not only improve college students' mood, but also reduce their stress levels, a study claims. Many universities have instituted "Pet Your Stress Away" programmes, where students can come in and interact with cats or dogs to help alleviate some of the strain, researchers said.

The scientists at Washington State University (WSU) in the US demonstrated that, in addition to improving students' moods, these programmes can actually get "under the skin" and have stress-relieving physiological benefits.

"Just 10 minutes can have a significant impact," said Patricia Pendry, an associate professor in WSU's Department of Human Development. "Students in our study that interacted with cats and dogs had a significant reduction in cortisol, a major stress hormone," said Pendry.

The study, published in the journal AERA Open, demonstrated reductions in students' cortisol levels during a real-life intervention rather than in a laboratory setting. The study involved 249 college students randomly divided into four groups.

The first group received hands-on interaction in small groups with cats and dogs for 10 minutes. They could pet, play with, and generally hang out with the animals as they wanted.

To compare effects of different exposures to animals, the second group observed other people petting animals while they waited in line for their turn. The third group watched a slideshow of the same animals available during the intervention, while the fourth group was "waitlisted."

Those students waited for their turn quietly for 10 minutes without their phones, reading materials, or other stimuli, but were told they would experience animal interaction soon.

Several salivary cortisol samples were collected from each participant, starting in the morning when they woke up. The students who interacted directly with the pets showed significantly less cortisol in their saliva after the interaction, researchers said.

"We already knew that students enjoy interacting with animals, and that it helps them experience more positive emotions," Pendry said.

"What we wanted to learn was whether this exposure would help students reduce their stress in a less subjective way. And it did, which is exciting because the reduction of stress hormones may, over time, have significant benefits for physical and mental health," she said.
