Our favorite biochemist, Karen Hurd, joins us again to discuss the difference between adrenaline and cortisol. 

Adrenaline gives us strength to fight or run, while cortisol reduces inflammation. These hormones are released simultaneously. We are meant to experience short bursts of adrenaline and cortisol in emergency situations, not prolonged baths in them all day every day while we sit at a desk, immobile. 

Luis and Karen discuss estrogen production after menopause, exercise and chronic pain, high testosterone in female bodies, and estrogen in male bodies. 

Stress is an endocrine disorder. If your diet is nourishing and balanced, but you are still stressed, consider your lifestyle, purpose and perception. Something has to shift when the mentality isn't connecting to biology in a way that is balanced.
