I also suggest checking out this website for the benefits of walking in nature:
From the website's introduction: Most of us sense that taking a walk in a forest is good for us. We take a break from the rush of our daily lives. We enjoy the beauty and peace of being in a natural setting. Now, research is showing that visiting a forest has real, quantifiable health benefits, both mental and physical. Even five minutes around trees or in green spaces may improve health. Think of it as a prescription with no negative side effects that's also free.
Our presbytery's geographic area is filled with wonderful wooded areas ... let me know where you like to walk and we may feature that site in a future Wellness Wednesday email or a PIES for Wellness link!
