![]() ![]() When researchers have observed the effects of breathing techniques like 4-7-8 breathing, they have seen an increase in theta and delta brain waves, which indicate someone is in the parasympathetic state, Robbins said. Researchers found the technique improved participants’ heart rate and blood pressure, according to a study published in July 2022. After participants had these health factors and their fasting blood glucose measured, they performed 4-7-8 breathing for six cycles per set for three sets, interspersed with one minute of normal breathing between each set. “The research on (the effect of) diaphragmatic breathing on these symptoms in general is spotty, with no clear connection due to the poor quality of the studies.”Ī team of researchers based in Thailand studied the immediate effects of 4-7-8 breathing on heart rate and blood pressure among 43 healthy young adults. “There is some evidence that 4-7-8 breathing helps reduce anxious, depressive and insomniac symptoms when comparing pre- and post-intervention, however, there are no large randomized control trials specifically on 4-7-8 breathing to my knowledge,” Tal said. While proponents may swear by the method, more research is needed to establish clearer links between 4-7-8 and sleep and other health benefits, he added. Activating the parasympathetic system also gives an anxious brain something to focus on besides “why am I not sleeping?” Tal said. The 4-7-8 breathing practice can help activate your parasympathetic nervous system - responsible for resting and digesting - which reduces sympathetic activity, he added, putting the body in a state more conducive to restful sleep. ![]() “An active sympathetic nervous system can cause a fast heart rate as well as rapid and shallow breathing.” When you’re stressed out, your sympathetic nervous system - responsible for your fight-or-flight response - is overly active, which makes you feel overstimulated and not ready to relax and transition into sleep, Dasgupta said. With practice you can slow it all down and get used to inhaling and exhaling more and more deeply,” his website advised. “If you have trouble holding your breath, speed the exercise up but keep the ratio (consistent) for the three phases. ![]() Not getting enough sleep?
