“Certainly HRV, high HRV is associated with better sleep. Low HRV is associated with conditions like insomnia and sleep apnea. Non-restorative sleep will negatively impact HRV, so there is this circular effect”

Dr. Lagos: Consistent meal timing creates physiological safety and maximizes HRV
“What I see more frequently is that when we time the expected time that you eat, irrespective of what you're eating, but that you eat generally at the same time, let's say seven o'clock, one o'clock, six o'clock, five days a week, the body feels safe. It can pr…”

“My colleagues at Rutgers looked at what happens To the brain during resonant frequency breathing. And what they found through MRIs was something called vasovagal constriction. So during stressful moments, the blood vessels would constrict to shunt blood flow a…”
Dr. Lagos: Innately High HRV Correlates With Endurance Athletes

Dr. Lagos: Moderate caffeine doesn't impact HRV, but five-plus cups harms performance
“Two cups of coffee for most people doesn't have a huge impact on heart rate variability such that if you're a performer and you have a competition, I would, I wouldn't say that having two cups of coffee is really going to impact you. Having five cups or more s…”
