Sensors and equipment used for physiological data collection were attached to the participants, including electroencephalography (EEG) and electrocardiography (ECG) sensors, thoracic and abdominal piezoelectric breathing bands, and Portapres technology on the left hand to measure beat-to-beat blood pressure (BP). Participants were comfortably sitting on an armchair in a soundproof and temperature-controlled bedroom at the SRI International Human Sleep Research Laboratory.

However, 30-40% of the participants experienced some trouble slowing down their breathing. During the intervention, all participants were able to achieve the targeted 0.1 Hz breathing rate, and the majority experienced no discomfort associated with the VR exposure. No significant changes were detected for cognitive arousal levels. ![]() The intervention resulted in acute autonomic and cortical modulation ( p < 0.05), leading to reduced physiological arousal (↓heart rate, ↓cortisol) compared with the control condition, with similar effects in adolescents with and without insomnia. In this study, we describe the rationale, supported by preliminary data, for a novel, digital, immersive virtual reality (VR)-based mind-body approach, designed to reduce bedtime arousal in adolescents with insomnia.įifty-two high-school students (16-20 years 32 female) with ( N = 18) and without ( N = 34) DSM-5 insomnia symptoms engaged with 20 min of immersive VR-guided meditation and paced breathing (0.1 Hz) ( intervention condition) and 20 min of quiet activity ( control condition), right before bedtime, on two separate evenings. ![]()
