About

This is a randomized controlled human exposure crossover study, aims to explore the health benefits of indoor plants on cardiopulmonary system on adults.

Full description

The researchers will conduct a randomized cross-controlled trial involving 48 healthy adults in Hangzhou, China. These participants will be randomly assigned into two groups, each comprising 24 individuals. Each participant will undergo two separate exposures in an office setting: one exposure without any plants present, and another exposure with 34 to 38 potted plants. A washout period of at least 4 weeks will be implemented between the two exposures. Questionnaires, physical examinations and the collection of biological samples will be conducted prior to exposure and after exposure. In addition, the monitoring of negative air ion, air pollutants and noise exposure, as well as collection of environmental microbial samples, will be conducted on weekdays. Researchers will gather samples of blood, urine, nasal secretion, and exhaled breath condensate from participants.
