Abstract:
Given the widespread concern over university students' psychological health and the significant role of biological sounds in psychological recovery, this study experimentally verified the effects of forest park biological sounds on stressed university students. We recruited 32 students (stress measured via the Perceived Stress Scale), used 11 biological sound samples from Henan forest parks as auditory stimuli, and tested their electroencephalogram (EEG) and psychological questionnaire in the laboratory. We find that biological sounds enhance security/relaxation and alleviate fatigue, with stronger effects in highly stressed students; Oecanthus indicus Saussure, Hirundo rustic, and Ardea intermedia exert the most positive effects, while Corvus macrorhynchos and Tettigonia chinensis Willemse have negative effects; Hirundo rustica, Oecanthus indicus Saussure, and Passer ammodendri score highest in psychological perception; and psychological and physiological responses correlate significantly. These findings highlight bioacoustics' value in relieving student stress and provide data for future forest park landscape and soundscape design.

The Role of Exercise in Stress Management
Regular physical activity is essential for reducing stress and promoting cardiovascular health. Exercise strengthens the heart, enhances blood flow, keeps blood vessels flexible, and helps lower blood pressure, all of which reduce the body's stress response. Research shows that adults who exercise regularly have nearly half the risk...
