Feeling 'brain fatigued?' Recharge your mind and body with forest therapy

For a healthy mind and body, let nature work its magic.

Forest therapy — walking through the woods, using your senses to connect with nature, staying in the present moment, no phones allowed — is taking off in the U.S. as a way to restore sanity.

Going into nature changes how your brain works. It also reduces stress levels and boosts measures of well being.

Inspired by Shinrin-Yoku, or “forest bathing,” a concept that began in the 1980s in Japan, the practice can offer powerful health benefits, said Amos Clifford, founder and director of the Association of Nature and Forest Therapy Guides and Programs.

He sees people become more relaxed and happier. As stress goes away, they start looking at their life in a new way. Some find relief for their chronic pain or insomnia.

What is it about nature that’s so soothing?

“It’s home. We evolved out of the forests and there’s something really deep in us that has a sense of recognition of forests. We seem to be wired for it,” Clifford told TODAY.

“We see a reset of the nervous system, where people start coming back to a healthier baseline. They’re away from their devices, they’re not in traffic, they’re not watching the 24-hour news cycle… they’re very much in the present moment.”

“The body, in those circumstances, has this incredible capacity for healing itself.”

Science backs up those findings. Going into nature changes how your brain works; it reduces stress levels and boosts measures of well being, said David Strayer, a professor of psychology at the University of Utah, who studies cognition and nature.

One big reason: You leave your technology behind.

“It’s a contrast between our modern, plugged-in, frenetic, on-the-go, connected-to-social-media, sleeping-with-your-phone-under-your-pillow modern world,” Strayer said.

This lifestyle constantly taxes and over-stimulates your prefrontal cortex — the thinking, problem-solving part of the brain — and makes you “brain fatigued,” he noted.

When you’re enjoying nature, you can rest the prefrontal cortex. You're more in the moment rather than ruminating about your problems. The parts of the brain associated with being mindful and in a meditative state become more active, he noted.

There’s also the exercise component, which has positive effects on mood, memory and cognitive function.

Researchers see the changes quickly. People report that they see benefits even in working outdoors and gardening.

“If you can manage to get yourself to a park, place to walk, jog, just enjoy, be in nature and leave the phone behind for 30 minutes, you start to see benefits,” Strayer said.

“But if you’re picking up your phone constantly while you’re out in nature, or you’re just hopping back in front of the computer as soon as you get back in after a walk, you’re not getting anywhere near the [benefits.]”

The ultimate rewards happen after three days of being out in nature, Strayer said.

Forest therapy: What to expect

To experience the full benefits, you must leave your phone behind.

Forest therapy is consistent with what we know about why being in nature is so good for us, Strayer said.

A typical forest therapy group walk with a guide lasts about three hours. It’s not about rushing or hiking, so you won’t go far — perhaps half a mile. Guides choose easy, gentle trails, so you don’t have to be fit. The walk could be in a city park or in a more remote forest.

To focus on being mindful, the guide will give a series of “invitations” — asking you to notice the sounds of a stream or the feel of dirt in your hand, for example.

“That helps people get progressively more connected to their senses and to their bodies and to the place they’re in, and to really just slow down and relax,” Clifford said. “What are you drawn to? What about this is enjoyable?”

A guided group walk typically costs about $30 per person. It’s useful to start off with a guide so you get the hang of what the practice is about. You can find a list of trained guides here.
