The Most Ignored Muscle in Your Body Could Be Affecting Your Sleep, Breathing & Health

What if one of the most overlooked parts of your body was influencing far more than your ability to speak, chew, and taste?

Right now, without changing anything, notice where your tongue is resting. Is it pressed against the roof of your mouth? Sitting behind your bottom teeth? Is your jaw clenched? Are your lips apart?

Most people have never consciously thought about their tongue's resting position. Yet in this solo episode of the SuperLife Podcast, Darin Olien explores the surprising connections between the tongue, breathing, facial development, sleep, blood pressure, posture, and even the way we experience food.

Darin argues that four modern conveniences have fundamentally changed how we use our tongues: soft processed foods, habitual mouth breathing, antiseptic mouthwash, and forward-head posture from excessive screen use. He explores research into jaw development, the oral microbiome, nitric oxide production, sleep apnea, and the intricate muscular and fascial connections throughout the body.

From the long-debunked tongue taste map to the relationship between oral bacteria and blood pressure, Darin reveals how much we still have to learn about this remarkable muscular structure. He also discusses why chewing real food matters, how nasal breathing supports normal airway function, and why tongue exercises are being investigated as a complementary approach to certain breathing and sleep problems.

Most importantly, this episode is about taking action. Darin shares practical habits for improving tongue awareness, supporting oral health, reducing unnecessary jaw tension, and becoming more conscious of how you breathe throughout the day.

He finishes with a guided two-minute tongue exercise routine that you can begin practicing immediately.

Your tongue works for you every single day. Maybe it's time to start paying attention to it.
