Indoor Plants Could Improve Air Quality and Cooling, Global Study Finds

A new study led by the University of Surrey's Global Centre for Clean Air Research (GCARE) suggests that indoor plants may offer measurable benefits for air quality and cooling in homes and offices. The research, published in Eco-Environment and Health, reviewed multiple studies from around the world to assess how greenery inside buildings affects the environment. The team of 35 international experts found that plants can help remove some pollutants and lower indoor temperatures through natural processes. While the effects vary by plant type and setting, the findings point to a low-cost, nature-based strategy for healthier indoor spaces. As urban populations spend more time indoors, these insights could guide building design and public health recommendations. The study underscores the need for further research on optimal plant selection and placement to maximize benefits.
