How to Enhance Your Immune System | Dr. Roger Seheult

Maintaining a robust immune system and accelerating recovery from viral infections relies on fundamental pillars of health, including nutrition, exercise, and consistent sleep. Sunlight exposure, particularly the infrared spectrum, plays a critical role by penetrating skin and tissues to stimulate mitochondrial function and on-site melatonin production, which acts as a powerful intracellular antioxidant. Beyond sunlight, deliberate heat exposure through hydrotherapy or saunas can elevate core body temperature, triggering the innate immune system to release interferon, a broad-spectrum antiviral. Managing environmental factors like light exposure at night is equally vital, as even minimal light can disrupt circadian rhythms and glucose metabolism. Supplemental strategies, such as N-acetylcysteine, serve as effective mucolytics and glutathione precursors, helping to mitigate severe symptoms during illness. These evidence-based protocols offer actionable, low-cost tools for enhancing metabolic health and resilience against infectious diseases.
