Full Show Notes: https://bengreenfieldlife.com/lnleland/ You can train hard and eat well, and still overlook some of the biggest forces shaping your health. In this LIFE Network replay, I am joined by Dr. Leland Stillman, an integrative physician who looks at health through a much wider lens: light, air, water, toxins, electromagnetics, circadian biology, and nervous system balance. We get into why two people can be exposed to the same virus or stressor—and have wildly different outcomes—and how factors like methylation, heavy metals, nutrient status, and environmental load determine whether your body adapts—or slowly breaks down under stress. We also cover a lot of practical ground, including: - How sunlight, indoor lighting, and circadian rhythms influence hormones, mood, and immune function - How EMFs, glyphosate, and environmental toxins can compound stress—and realistic ways to reduce exposure at home - Why nervous system balance, breathwork, and oxygen physiology matter for longevity and recovery - Melatonin production, red and infrared light, and nighttime routines that support deep sleep - Why diet must be personalized—and how advanced lab work helps identify what your body needs - What cold exposure, circadian extremes, and even mammals like polar bears can teach us about metabolic health Dr. Stillman doesn’t chase trends or protocols in isolation. He focuses on root causes—and on addressing light, nutrition, toxins, electromagnetics, and mindset together, not piecemeal. If you’ve ever felt like you’re doing “everything right” but still not getting the results you want, this conversation will likely reframe how you think about health.
