The Landscape and Human Health Laboratory (LHHL) is a multidisciplinary research laboratory dedicated to studying the connection between greenery and human health.


The LHHL uses its findings to promote policies to:

    • Increase the use of and care for green landscaping to help individuals, families, and communities flourish
    • Suggest locations for green landscaping where the environment is most challenging and relief is most needed
    • Aid in the design of green landscapes so that they are as effective in promoting human health as possible

We examine the impacts of natural features—trees, grass, flowers, and green spaces—on:

  • Safety, crime, violence, and aggression
  • Strength of community
  • Well-being, coping, and vitality
  • Attention, executive-functions, self-control, learning

The populations we study include underserved groups, such as:

  • Elderly adults
  • Impoverished, inner-city adults and children
  • Children with and without Attention-Deficit/Hyperactivity Disorder

Our research settings include:

  • Urban public housing in Chicago
  • Home- and play-settings from the Mid-west and across the U.S.A.
  • Chicago Public Schools
  • Urban parks, neighborhoods, and commercial areas in Champaign-Urbana, Illinois
  • Laboratory simulations of green and built environments
