Some runners taking part in the Boston Marathon say they run to improve their mental health, and one New Hampshire psychologist has incorporated running into her practice.Dr. Beth Connolly, of Hampton, says her office is a safe, happy space for her patients. With her love of running, she calls it her "happy pace.""There are many parallels between running and life," she said.Connolly is running her 10th Boston Marathon this year and has raised more than $130,000 for Dana Farber in the process.>> Download the free WMUR app to get updates on the go: Apple | Google Play <<"The meaning and purpose that it creates in my world, in my life, and how much of a part it's just been intertwined with Boston," she said.Connolly has run 105 marathons in 38 states, most of them with her husband, Joel. In 2021 alone, she ran 17 marathons.She said running doesn't intersect with her career; it moves on the same track. She said she prefers to use motion, running or walking, as she treats her clients."We know that movement is healing, and it facilitates change. It facilitates healing both in the body and the mind, which are interconnected," she said. "This is my passion. I'm excited about it. It's innovative. It's outside of the box."The therapy sessions usually begin in the office, but then they move to the backroom treadmill or outside."Even if I did and said nothing else and I brought you outside, and I started to walk with you, something is happening," Connolly said. "Something good is happening in your body. Something good is happening in your mind."She said getting out and moving can trigger changes."Once we start challenging ourselves and creating a little bit of stress, which is what happens when we run, it allows us to have access to some of that vulnerability and some of the ways that we naturally approach our lives and the ways that we think about our experiences," she said.Earlier this week, News 9 profiled a Windham teenager who said he suffers from depression and feels isolated, and running is critical for his mental health. While Connolly has never met him, she said she understands completely how running helps him."He is treating himself every time he goes for a run," she said. "He is treating his anxiety, and he is giving his brain access to things that he needs in order to really regulate himself."Watch complete Boston Marathon coverage Monday on WMUR-TV, WMUR.com, the WMUR app and the Very Local app.
