Just 20 minutes of contact with nature will lower stress hormone levels, reveals new study from Science Daily

"We know that spending time in nature reduces stress, but until now it was unclear how much is enough, how often to do it, or even what kind of nature experience will benefit us," says Dr. MaryCarol Hunter, an Associate Professor at the University of Michigan and lead author of this research. "Our study shows that for the greatest payoff, in terms of efficiently lowering levels of the stress hormone cortisol, you should spend 20 to 30 minutes sitting or walking in a place that provides you with a sense of nature."

I experienced the same thing as above first-hand when we move from an urban area to a cul-de-sac with masses of trees in our backyard and lots of green grass. I wrote about it in The Importance of Creation and the Impact of Green Space.
