"The Key to Better Sleep: A Doctor's Trusted Exercise"

Dr. Kunal Sood, a Maryland M.D. with a large TikTok following, recommends resonance frequency breathing as the number one way to improve sleep. This simple exercise involves inhaling and exhaling for a count of five, slowing down breathing to about six breaths per minute and increasing heart rate variability, which activates the parasympathetic nervous system to decrease sleep onset and improve sleep quality. Fans have reported positive experiences with the technique, and research supports its ability to lower stress, blood pressure, and improve mood.
