(DC) (Friends of the National Arboretum) Join our nature and forest therapy guide in this two-hour program that encourages you to slow down and take in the National Arboretum through all your senses. Forest bathing, or shinrin yoku, is the simple practice of taking in the woods through the senses for health benefits. The benefits are immense: boosted immunity, lowered blood pressure and heart rate, improved attention and mood, and hitting the reset button on life. The Japanese have enjoyed shinrin yoku for decades as a regular public health initiative.
