10 Very Human Benefits of Trees

I’ve been writing a few posts on trees lately to go along with this month’s poll (see sidebar). I’ve learned a lot of great things that are worth sharing.

Here is my list of:

10 Reasons that Trees are Good for Humans.

(Sources listed at bottom of post)

1. Trees help children concentrate: Children who have parks and trees to play around concentrate better. MC

• Children have been shown to retain more of the information taught in schools if they spend some of their time outdoors in green spaces. BG
• Girls with a home view of nature score higher on tests of concentration and self-discipline (DDOT)
•  Attention Deficit Disorder (ADD) symptoms in children are relieved after spending time in nature; the greener the setting, the more the relief (DDOT)

2. Trees reduce stress: Trees, community gardens, and parks can help reduce physiological stress and aesthetically improve an area. MC

3. Trees lower UV-radiation: Trees provide shade from harmful ultraviolet radiation, particularly in playgrounds, schoolyards, and picnic areas. MC UV radiation is what causes skin cancer

4. Trees reduce crime:  The psychological benefits of an urban forest can reduce property crime by 48% and violent crime by 56%! Dc.gov Aggression and violence are reduced with nature nearby (DDOT)

5. Trees strengthen neighborhoods: When neighborhoods are full of trees, residents spend more time outside mingling with neighbors—building personal ties, stronger communities, and a greater sense of well being. MC

6. Trees help heal - Hospital patients have been shown to recover from surgery more quickly when their hospital room offered a view of trees. BG

8. Trees Calm Traffic - The Institute of Transport Studies at England’s University of Leeds has found that street tree plantings have a traffic calming effect. Tree lined streets act as psycho perceptive measures, which subtly slows traffic and encourages speed limits of 25, 30 or 35 mph by making roadways appear narrower. PT

9. Trees provide food – almost too obvious to list, but so important to all of us!
