Veterans with PTSD who took either nature hikes or urban hikes reported that the hikes reduced stress and made them feel more connected with others. PTSD symptoms were reduced in both groups at the end of the trial (12 weeks), but symptoms increased back to baseline at week 24 in the urban hiking group. However, this was a secondary outcome that the study was not designed to answer.
