Forest Bathing, or Shinrin Yoku may be the hot new trend in self-help books this year. It means "taking in the forest atmosphere" and is considered a cornerstone of preventative health care and healing in Japanese medicine. By taking a leisurely walk through a natural area you can reduce your stress levels, improve your mood and see an increase in happiness. Or you might just get ticks. See some books below to see if forest bathing is right for you.
