In this video, the powerful impact of cortisol, the stress hormone, on the immune system is explored. While cortisol is utilized therapeutically in creams for skin conditions and autoimmune diseases, its link to immune suppression raises concerns, especially in the context of viral infections. The video discusses recent findings indicating elevated cortisol levels in infected patients, leading to increased complications and reduced survival rates. To protect against infections and their complications, the video suggests practical strategies such as using nutritional supplements (including vitamins A, D, E, essential fatty acids, melatonin, and pregnenolone), reducing calorie intake, avoiding sugar and processed foods, and adopting relaxation techniques like deep breathing and meditation, even if practiced briefly each day. Lowering cortisol levels emerges as a key factor in preventing infection-related complications and mortality.
