19:11 Lena: Okay, so we've painted this picture of how trauma creates these cascading biological effects. But I don't want to leave our listeners feeling hopeless. What can people actually do about this?
19:23 Miles: That's the most important question, and the good news is that there are evidence-based approaches that can help heal both the trauma and its biological effects. The key is understanding that healing needs to address multiple levels simultaneously.
19:38 Lena: What do you mean by multiple levels?
19:40 Miles: Well, you need to work on the psychological level, the nervous system level, and the gut level all at the same time. They're all interconnected, so addressing just one piece often isn't enough for lasting healing.
19:52 Lena: Let's start with the nervous system piece. What can people do to regulate their nervous system?
19:57 Miles: One of the most powerful tools is something called vagus nerve stimulation. Remember, the vagus nerve is that communication highway between your brain and gut. When it's functioning well, it helps activate your "rest and digest" response.
20:10 Lena: How do you stimulate the vagus nerve?
20:12 Miles: There are actually lots of simple techniques. Deep breathing exercises, especially exhaling longer than you inhale, can activate the vagus nerve. Cold exposure—like cold showers or ice baths—can also be helpful. Humming, singing, or gargling can stimulate the vagus nerve because it innervates your throat muscles.
20:28 Lena: Those sound pretty accessible. What about the gut piece?
20:32 Miles: Diet is huge here. Anti-inflammatory foods can help reduce the chronic inflammation we've been talking about. Think omega-3 fatty acids from fish, polyphenols from berries and dark leafy greens, and fiber-rich foods that feed beneficial gut bacteria.
20:46 Lena: Are there specific foods that are particularly healing for trauma survivors?
20:50 Miles: Fermented foods can be really helpful because they introduce beneficial bacteria to the gut. Things like yogurt, kefir, sauerkraut, and kimchi. Bone broth is also great because it contains amino acids that can help heal the intestinal lining.
21:03 Lena: What about supplements?
21:04 Miles: Probiotics can be helpful, but it's important to work with someone knowledgeable because different strains do different things. L-glutamine is an amino acid that can help repair the intestinal lining. Omega-3 supplements can help reduce inflammation.
21:16 Lena: And on the psychological level?
21:18 Miles: Trauma-informed therapy is crucial. Approaches like EMDR, somatic experiencing, and trauma-focused cognitive behavioral therapy have all been shown to help. But here's what's interesting—some of these therapies might actually reverse some of the biological changes we've been talking about.
21:34 Lena: Really? Therapy can change your biology?
21:37 Miles: There's emerging research suggesting that successful trauma therapy can reduce inflammatory markers, improve vagus nerve function, and even influence gene expression. It's like the healing happens on multiple levels simultaneously.
21:49 Lena: What about lifestyle factors?
21:50 Miles: Exercise is incredibly powerful for trauma recovery. It helps regulate the nervous system, reduces inflammation, and can improve gut health. But it needs to be the right kind of exercise—gentle, mindful movement is often more helpful than intense workouts that might re-traumatize the nervous system.
18:17 Lena: What does that look like practically?
22:07 Miles: Things like yoga, tai chi, walking in nature, or swimming. The key is movement that feels safe and allows you to stay connected to your body rather than dissociating from it.
22:17 Lena: This is making me think about sleep too. How does sleep fit into all of this?
22:21 Miles: Sleep is absolutely crucial. Trauma often disrupts sleep patterns, but poor sleep also perpetuates inflammation and impairs gut function. Good sleep hygiene—consistent bedtimes, cool dark rooms, avoiding screens before bed—can be incredibly healing.
22:36 Lena: Are there any other lifestyle factors that are particularly important?
22:39 Miles: Social connection is huge. Remember how we talked about social support buffering the cellular aging effects of trauma? Having safe, supportive relationships isn't just nice to have—it's biologically protective.
22:50 Lena: So healing from trauma isn't just about individual therapy—it's about creating a whole lifestyle that supports healing?
0:42 Miles: Exactly. And it's important for people to understand that this kind of healing takes time. These biological changes didn't happen overnight, and they won't reverse overnight either. But the research shows that with consistent, comprehensive approaches, significant healing is possible.
