The Calm Lab Podcast
Nervous system education for bodies that won't settle
Welcome to The Calm Lab — a podcast about nervous system regulation, trauma-informed healing, and what it actually takes to feel safe in your body.
Hosted by Kassandra, a trauma-informed yoga teacher and nervous system educator.
If you've ever felt like your body won't cooperate — like you know you should relax but you can't — this podcast is for you.
Each episode, we explore:
- Polyvagal theory and how your nervous system works
- Why trauma lives in the body (and how to release it)
- Vagal toning, breathwork, and somatic practices that actually work
- Conversations with therapists, somatic practitioners, and researchers
This isn't surface-level wellness advice. We go deep into the science and the practice of nervous system regulation.
Whether you're healing from trauma, managing chronic stress, or simply trying to sleep better, you're welcome here.
New episodes Bi-weekly Mondays.
Breathe. Move. Learn.

You've probably tried to relax before and found your body just
wouldn't cooperate.
This practice is different.
We're not asking you to relax. We're giving your nervous system
something it actually understands — direct physiological signals
of safety.
Through vagal toning, humming, body rotation, and extended exhale
breathing woven into a 20-minute yoga nidra — your nervous system
receives what it's been waiting for.
All you have to do is lie down and receive.
Let's figure this out together.

Welcome to the Calm Lab. I'm Cassandra. Today's episode is a practice. You don't need to be anywhere special. You just need a few minutes and a willingness to let your body do what it already knows how to do. What we're doing today is a bagel toning Yoga Nidra. Yoga Nidra is a state of consciousness between waking and sleeping. Deeply restorative, deeply regulating. When we layer in vagal toning practices that directly stimulate your vagus nerve, we're not just relaxing, we're giving your nervous system a direct experience of safety. If you've been feeling wired, depleted, or like your body just won't settle, this is for you. Find somewhere you can lie down, a bed, a couch, the floor, anywhere you can be fully supported. If lying down isn't available right now, settle into your seat, feet flat on the floor, hands resting open on your thighs. When you're ready, let's begin. Allow your eyes to close. Before we do anything, I just want you to notice where you're arriving from. Take one breath in through your nose and a long slow breath out through your mouth. Again, inhale. And exhale. Let it be longer than the inhale. One more breathe in and breathe out all the way until the breath is completely gone. Your vagus nerve just received its first signal that you are safe. We're going to begin with something that might feel almost too simple, humming. Your vagus nerve runs through your vocal cords. When you hum, especially on a long slow exhale, you are directly stimulating vagal tone. You are sending a vibration through the very nerve that governs your rest and digest state. This isn't metaphor, this is physiology. Take a breath in through your nose. And on the exhale, let a gentle hum come out. It doesn't have to be musical, it doesn't have to be pretty. And hum. Letting the sound fade naturally as the breath runs out. Again, inhale. Feel the vibration in your chest, in your throat, maybe even behind your sternum. That vibration is medicine. Two more inhale. And one final time, a long slow breath in, and a long, slow hum. Letting it dissolve completely. Notice if there is a softening anywhere, a slight heaviness in the limbs, a warmth in the chest. That's your parasympathetic nervous system coming online. Now we'll move awareness through the body. Not to relax each part, but to contact each part. To let your nervous system know I'm here, I'm safe. All of me is here. I'll name each area, simply bring awareness there. That's all. Right thumb, index finger, middle finger, ring finger, little finger, palm of the right hand, back of the right hand, right wrist, right forearm, elbow, upper arm, right shoulder, right side of the chest, right side of the waist, right hip, right thigh, kneecap, right calf, ankle, right heel, sole of the right foot, right big toe, second toe, third toe, fourth toe, little toe, heart center, left thumb, index finger, middle finger, ring finger, little finger, palm of the left hand, back of the left hand, left wrist, left forearm, elbow, upper arm, left shoulder, left side of the chest, left side of the waist, left hip, left thigh, kneecap, left calf, ankle, left heel, sole of the left foot, left big toe, second toe, third toe, fourth toe, little toe, right shoulder blade, left shoulder blade, the whole of the back, the spine, the back of the head, the crown of the head, the forehead, right temple, left temple, right ear, left ear, right eye, left eye, right nostril, left nostril, upper lip, lower lip, the chin, the throat, the right collarbone, the left collarbone, the chest, the heart center, the belly, the navel, the pelvis, the base of the spine, the whole right leg, the whole left leg, the whole right arm, the whole left arm, the whole torso, the whole body, the whole body resting, the whole body breathing the whole body safe. A short true statement about who you are or who you're becoming, not a goal, not an aspiration, a recognition of something that's already true at the deepest level, even if this surface hasn't caught up yet, some possibilities or allow one to arise naturally. My nervous system knows how to heal. I am learning to feel safe in my body. Rest is available to me. I am supported. Whatever arose, let it land in the body like a stone dropping into still water. Say it twice more silently to yourself, and then release it. The most powerful intentions are planted and let go. Trust that something heard. Now I'm going to offer you a series of images. Allow them to arise and dissolve quickly like clouds passing. Don't hold on, don't analyze, just receive a warm fire, the ocean at dusk, a field of tall grass moving in the wind, a hand reaching out to you, the feeling of sunlight on skin, a door opening into a room full of light, rain on a window, a forest floor, soft, dark, and safe, your own body breathing, the sound of your heartbeat, a vast open sky, stillness. Just noticing the natural rise and fall. And if you're willing, let's do one more round of extended exhale together. Inhale through your nose for four counts, two, three, four, exhale through your mouth for eight counts, two, three, four, five, six, seven, eight, again, inhale. Exhale longer than the inhale. One more, breathe in, and a long slow exhale, letting everything go. Your vagus nerve has been toning throughout this practice. Your nervous system has been receiving signal after signal that you are safe. This is not small work. Slowly begin to bring awareness back to the room around you without opening your eyes yet. Notice the sounds in your environment, the temperature of the air, the feeling of the surface beneath you. Begin to deepen the breath slightly. Let small movements return. Fingers, toes. A gentle roll of the wrists and ankles. When you feel ready, draw the knees into the chest. If you're lying down, roll to one side, rest there for a moment. There's no rush. When you're ready, press yourself up to seated. And take one final moment of stillness before you move back into your day. Thank you for practicing with me today. What you just did, the humming, the body rotation, the breath, these aren't passive relaxation techniques. They're direct communications to your vagus nerve, to your nervous system. Signals that say the day is over, you are safe, you can rest. If you noticed even a slight softening, a heaviness, a quiet, that's your parasympathetic nervous system responding. That's real. That's in your body right now. Practice this regularly, and that response gets stronger. Your baseline lowers, safety becomes more available to you, not just in this 20-minute practice, but throughout the day. If you want to go deeper, the free seven-day nervous system reset protocol is linked in the show notes. And if today's practice resonated, I'd love to know.
