lower heart rate with combined audio-visual nature stimuli at 26°C
Combined audio-visual natural stimuli reduced heart rate by 6.08% at 26°C
A controlled climatic chamber experiment with 24 participants tested three types of natural stimuli (visual, auditory, and combined audio-visual) under three operative temperature conditions (26°C, 28°C, and 32°C). At the comfortable 26°C condition, the combined audio-visual stimuli group showed the greatest physiological response, reducing heart rate by 6.08%. However, at 32°C, most physiological and psychological restoration indicators showed no significant changes, suggesting that thermal stress may override the restorative benefits of nature stimuli.
At 26 °C, the combined audio-visual stimuli group reduced heart rate by 6.08%.
