Trees help prevent asthma and respiratory diseases finds study

Trees create clean air and asthmatics and respiratory issues need clean air.  Not rocket science really is it? 

This study by a group of researchers at Portland State University, used sensors in different neighbourhoods, to measure nitrogen dioxide levels.

They found the following:

  • Children age 4-12 stayed at school for 7,380 more days per year
  • There were 54 asthma-related emergency room visits avoided – basically one per week that did not happen – in just one community
  • There were 46 fewer hospital stays for the elderly
  • The health benefits created $6.6 million in cost savings to the community…
