Background and Objective: In recent years, sleep problems have been increasing globally, there exists an urgent need to develop a therapeutic program promoting sleep quality. This study investigated the effect of three types of deep breathing cycles programs on heart rate (HR) and sleep parameters in healthy young adults.
Methods: Thirty healthy participants were recruited. HR and sleep parameters were measured via a smartwatch in all participants for two consecutive days. Participants were randomized into the forced deep breathing cycles (FDBC), non-forced deep breathing cycles (N-FDBC) and breathing control (BC) groups, with each participant performing the breathing cycle programs before sleep latency for 30 minutes.
Results: N-FDBC showed a significant increase in sleep quality (p < 0.001), time in bed (p < 0.05), and total sleep time (p < 0.001), as well as a significant decrease in sleep latency and %awake during sleep (p < 0.001). During sleep, maximum HR, minimum HR, average awake HR during sleep, average light sleep HR, and average deep sleep HR were significantly lower (p < 0.01). For the FDBC group, significant increases in sleep latency (p < 0.05) and decreases in %awake during sleep (p < 0.05) were observed. HR before sleep was higher (p < 0.01). Average HR while awake during sleep and light sleep stages significantly decreased (p < 0.001). Such changes in all parameters were not observed after the BC group.
Conclusions: Our study demonstrates that N-FDBC yields clinical benefits by improving sleep quality and HR response during sleep in healthy adults.
