Abstract: Laboratory analysis of behavioral and physiological data on rhythmic deep diaphragmatic breathing (DB) upon presentation of sound 6 times/min. The experiments were conducted before and after training at home (the data from these workouts were not analyzed). The study involved 17 subjects (9 women). Registration of four experiments: 1) Background (20 min.) with spontaneous breathing and pressing the button + 5 minutes with DB (sound 6 times/min); 2) 5 minutes background with spontaneous breathing and pressing the button and 15 minutes with sound 6 times/min, DB when pressing the button, when pressing stops - breathing as in a dream; 3) 5 minutes background with a button and 30 minutes with a sound 6 times/min, DB and spontaneous breathing as in the previous experiment; 4) background (20 min.) with spontaneous breathing and pressing a button. In all experiments, pressing a button, 20 EEG channels, an electrocardiogram (ECG), and abdominal breathing were recorded. For experiments 2 and 3, statistical analysis was performed: the number of falls asleep according to the button analysis, EEG power in the alpha and delta ranges, ECG heart rate (HR) and heart rate variability (HRV). In experiment 3, compared with experiment 2, a statistically significant increase in the duration and frequency of falling asleep was shown, the power of the alpha rhythm significantly decreased when falling asleep in experiments 2 and 3, the power of the delta rhythm significantly increased when falling asleep in experiments 2 and 3. HR significantly decreased in three conditions: background – DB – sleep, HRV increased insignificantly only in DB. .
