This episode I describe the biology of two essential hormones we all make: cortisol and adrenaline (also called epinephrine). Cortisol and adrenaline powerfully regulate our levels of energy, focus and immune system function. I describe various science-supported tools and practices to increase or decrease cortisol and/or adrenaline, depending on one's specific needs and goals. I also describe the biology of nootropics, and how cortisol and adrenaline can improve or degrade learning. Finally, I review the scientific data and tools for timing the release of these hormones to improve memory, energy and immune system function.
