I’m constantly looking for new ways to help people who want to make the transition from a sedentary to a more active life. I’ve finally realized that the simplest thing I can do in my classes, for example, is add a couple of stretches for every hour of class. Maybe feeling the difference a couple of stretches can make will inspire us all to do a little more.
I’m like a broken record when it comes to the benefits of walking, especially outdoors (green exercise, it’s called). Mostly I talk about it because I love it, and I feel the benefits—it’s the best stress relief I’ve ever found, and I think it does more to support my health than any other activity I do.
Here’s what Psychology Today has to say about green exercise:
Outdoor exercise makes people happier, less fatigued and angry, more tranquil and relaxed, and bestows a more lasting energy boost compared to indoor exercise. Even five minutes of green exercise (like walking across a park or campus) is likely to boost self-esteem and mood. Green exercise is experienced as more restorative and is more likely to increase a person’s frequency of exercise compared to indoor exercise, and all these effects are enhanced with both duration and intensity of outdoor exercise.
Improved self-esteem and mood in 5 minutes? Who doesn’t need more of this?
However, a 2010 study from Boston University Medical Center compared the effects of Iyengar yoga classes against the benefits of walking on 34 healthy people. The results showed that compared with walking, “yoga appears to be accompanied by greater improvement in mood and decrease in anxiety and a boost in the brain chemical associated with these benefits.”
The brain chemical referred to is the neurotransmitter GABA, low levels of which are associated with depressed mood and anxiety. The participants in the yoga groups showed higher GABA levels as well as reporting better mood compared to the walkers in the control group, who walked for an hour three times per week. In spite of the higher level of exercise in the control group, the yoga groups showed more improvement in mood.
Now, a new study from Boston University Medical Center looks at the effects of Iyengar yoga classes and deep breathing practice on 30 people with major depression. The study put participants in two groups; one attended yoga classes two times per week and practiced at home, and the other attended three classes per week as well as practicing at home. After twelve weeks, there was no difference between the affects on the two groups: all the participants experienced a reduction in their depressive symptoms. Good news, indeed.
Whether or not depression is an issue, any enjoyable way to reduce anxiety and improve mood is very welcome. We need those in our self-care toolkit.
