Nature, The Ultimate Healer.

<p>Here’s one silver lining to the pandemic: with gyms, museums, and stores closed, many of us were forced to spend more time outside. I was able to ditch my car and more safely pedal the 3.5 miles on pedestrian-friendly streets to work at Alta Bates Summit Medical Center in Oakland, where I work practicing hospital medicine. </p><img alt="" srcset="https://ggsc.s3.amazonaws.com/images/made/images/uploads/How_Nature_Helps_Us_Heal_300_200_int_c1-1x.jpg 1x, https://ggsc.s3.amazonaws.com/images/made/images/uploads/How_Nature_Helps_Us_Heal_600_400_int_c1-2x.jpg 2x" src="https://ggsc.s3.amazonaws.com/images/made/images/uploads/How_Nature_Helps_Us_Heal_300_200_int_c1-1x.jpg" width="300" height="200"><p>One morning last spring, I was reflecting on how good the ride outside made me feel when I walked in to see a 68-year-old patient with several significant behavioral and medical problems.</p><p>Before I could say a thing, he jumped in as if in mid-conversation. “Dr. Hass, I can’t thank you enough.

There are surprising social benefits, too. During early forest bathing experiments, physician Qing Li found that after a couple hours in the woods, blood pressure went down an average of five points. The effects didn’t end once people left the trees; stress hormones were measurably lower for a week.

Nature is, of course, an all-senses experience. It’s not just about looking at the trees—you can smell them, too, and hear the wind in their branches, and touch their bark.

It is quite obvious that we will be most comfortable at the place we originated and we finally take abode, i.e. nature.
