Good morning. Today we're gently exploring something reassuring: your body and mind are already equipped with remarkable systems for repair, resilience, and growth. Whether it's your brain's ability to form new cells, your immune system's daily patrol for abnormal cells, or your own capacity to begin healing old emotional patterns, the theme today is support, not fear. Let's look at a few small, evidence-informed ways you can nourish these systems.
You might find it comforting to know that change—whether emotional or physical—rarely requires a dramatic overhaul. According to Dr. Jordan Peterson, speaking on The Diary Of A CEO, recovery from depression, anxiety, or painful relationship patterns tends to follow the same pattern: find the smallest step you can honestly commit to, and take it. He shared a clinical example of a patient too depressed to leave bed who, starting with simply sitting upright for 30 seconds, was walking hospital hallways within two weeks. Dr. Peterson describes this progress as exponential rather than linear—slow at first, then accelerating, much like compound interest.
This idea of gently supporting your body's own capacity for change connects nicely with what Dr. Michael Nehls describes in his research on the hippocampus, your brain's memory and learning center. According to Dr. Nehls, the hippocampus is one of the few brain regions capable of growing new nerve cells throughout life—a process called neurogenesis—and this growth underlies curiosity, emotional resilience, and compassion. He points to lithium, a trace mineral naturally found in shellfish and some water sources, as one nutrient that may support this process by encouraging brain-derived neurotrophic factor (BDNF) and reducing neuroinflammation. He also references a 2025 study published in *Nature* from Harvard researchers, which found that among 27 trace elements measured in the brains of Alzheimer's patients, lithium levels were the one significantly correlated with disease stage. Dr. Nehls pairs this with the importance of omega-3 fatty acids and vitamin D, noting that the average American's omega-3 index is around 4%, compared to an ideal of 11%.
Your immune system tells a similarly hopeful story. As explained in the Dr. Eric Berg DC presentation, your body is constantly detecting and correcting abnormal cells—a process supported by proteins like p53 (sometimes called the 'guardian of the genome') and natural killer cells that patrol for irregularities. The presenter notes that just one night of only 4 hours of sleep can reduce natural killer cell activity by 30%, underscoring how directly your daily habits—sleep, movement, and blood sugar balance—influence these protective systems. Both Dr. Berg's presentation and pharmacist Mason Carnabi, speaking on Ben Greenfield Life, emphasize the value of knowing your own numbers: Carnabi described tracking his own vitamin D, cortisol, and lipid panel results to guide his supplement choices rather than following trends, a practice sometimes called biomarker-guided self-quantification.
1. **Pick one small, honest step.** As Dr. Peterson suggests, choose something so small you'll actually do it—tidying one drawer, sending one message, or sitting outside for five minutes. The size doesn't matter; starting the process does.
2. **Get outside or move gently after a meal.** Supporting healthy blood sugar and insulin balance was highlighted in the Dr. Berg presentation as a meaningful way to support your body's natural defenses, since chronically elevated insulin can act as a growth signal cells respond to.
3. **Protect your sleep tonight.** Given that the Berg presentation notes a single short night of sleep can measurably reduce immune cell activity, consider a calming wind-down routine—dimming lights, limiting screens, or a warm shower—to support restorative rest.
4. **Consider a conversation about your nutrient levels.** Following Mason Carnabi's approach of testing before supplementing, you might ask your provider about checking vitamin D, and discuss with them whether your omega-3 intake (through foods like fatty fish or algae-based sources, as Dr. Nehls recommends) is adequate.
5. **Nurture a connection today.** Dr. Nehls references research published in *Science* showing that positive social bonding—even eye contact with a dog—raises oxytocin, which may support hippocampal health. A short call with a loved one or time with a pet can be a gentle, feel-good addition to your day.
Please remember, this briefing is for educational purposes and is not a substitute for professional medical advice. Any changes to supplements—including lithium orotate, vitamin D, or others discussed by Dr. Nehls or Mason Carnabi—should be made in partnership with your healthcare provider, particularly if you take other medications or have kidney, thyroid, or psychiatric conditions. Dr. Peterson's discussion of trauma and exposure-based approaches to anxiety should be undertaken with a qualified mental health professional, not alone. If you are in crisis, please contact a crisis line immediately (in the US: 988 Suicide & Crisis Lifeline; in the UK: Samaritans 116 123). And as physicians discussed in a comparative healthcare panel noted, time-sensitive symptoms—such as chest pain, sudden weakness, facial drooping, or difficulty speaking—warrant calling emergency services right away rather than waiting to see if they pass.
