Abstract: The purpose of this study was to investigate the effectiveness of exposure to green space on absolute power of alpha wave and stress reduction in people with attention deficit hyperactivity disorder. The population of the present study includes 150 university students of Mohaghegh Ardabili in different stages grades with attention deficit/hyperactivity disorder (ADHD) in the academic year 2022-2023 who were selected using convenience sampling. Therefore, 32 volunteer students with the highest average score in attention deficit hyperactivity disorder were exposed to green space for 10 minutes. In order to collect the data, quantitative electroencephalography (QEEG) and Connors adult ADHD questionnaire (1999) and Ertanir et al.'s student stress questionnaire (2021) were used. For data analysis, the frequency data of brain waves, Neuroguide software was used, and for statistical analysis of quantitative data, Duncan's mean square test used statistical software Statistical Analysis System (SAS). The findings of the present study show that the effect of exposure to green space compared to the environment without green space on the absolute power of alpha waves in the anterior, central and posterior regions have a significant difference. Also, the results of the statistical analysis of the data obtained from the questionnaire tool were significant (P<0.05) in reducing the stress of people suffering from attention deficit/hyperactivity disorder. The results of the present research have shown that the changes in the absolute power of the alpha band in two different thinking situations indicate different functional mechanisms of alpha waves in different brain regions.
