University of Houston BRAIN Center study links nature exposure to reduced negative emotions

Published on: Mar 24, 2026

Exposure to fresh air and sunlight often recommended as a simple remedy now has strong scientific backing. Researchers at the University of Houston have found that spending time in natural environments is linked to reduced negative emotions and improved emotional well-being.

With nearly 90% of the U.S. population expected to live in urban areas by 2050, integrating natural elements into city planning and public health strategies is becoming a critical priority. Such efforts can play a significant role in enhancing mental health and overall quality of life.

A research team led by brain scientist Jose Luis Contreras-Vidal conducted a systematic review and meta-analysis involving 2,101 participants across 33 studies. Using neuroimaging techniques primarily EEG alongside psychological assessments, the team evaluated responses to real, virtual, and imagined natural environments.

The findings indicate that exposure to nature contributes to a more balanced emotional state, increasing positive feelings while reducing negative ones. The research also highlights that environmental factors, alongside genetics, play a key role in shaping brain health and what researchers refer to as “brain capital.”

Different forms of nature exposure showed consistent benefits:

• Imagery: Viewing natural scenes increased positive emotions and reduced negative ones across multiple studies.
• Virtual Reality: Nature-based VR experiences led to notable emotional improvements in most studies.
• Outdoor Walking: Direct interaction with nature through walking showed strong positive psychological effects.

The study underscores growing interest in understanding how nature influences brain function at a neurophysiological level. Researchers suggest future studies should expand EEG analysis to include advanced neural metrics like functional connectivity and incorporate standardized, real-world data along with AI to deepen insights.
