How to do a forest bath
Set aside the time necessary for this therapeutic exercise.
For a single forest bathing session, set aside two to four hours for an excursion that is at least a half-mile long. Keep in mind that this extended time frame involves several stops for becoming aware of your senses, moments of sitting still, and mindful immersion.
The time frame may be increased, but two consistent hours of exposure to this outdoor therapy environment will maximize noticeable improvements to mood and overall health. It is important to note that like any other therapeutic exercise, forest-bathing will require multiple sessions.
