The newly launched Healthy Trees, Healthy Lives website (https://healthytreeshealthylives.org/) is an excellent source of information on the health benefits of trees.

The Health Benefits section of the website divides 14 benefits into 4 categories: physical (skin, heart, lungs, pregnancies/newborns, comfort/heat reduction, nutrition, fitness), mental (peace of mind, vitality, brain), healing (fighting power, healing, health), and financial (healthcare savings). Each benefit is described in a sentence or two, and links to published research papers on each benefit are included.
