Stress Hormones: What You Need to Know


What your body does with stress šŸ‘‡ I think we can all agree that the holiday season is one of the most stressful times of year. Maybe you have a *sense* that it affects your health, but do you actually know why or how?



So letā€™s start there. There are 2 hormones to know: Cortisol & Adrenaline (also called Epinephrine). Here are the differences: 1ļøāƒ£ Adrenaline is released rapidly as an immediate response to stress, whereas cortisol is released in a daily rhythm regulated by the brain & the hypothalamic-pituitary-adrenal (HPA) axis. 2ļøāƒ£ Adrenaline has fast effects to activate the body when in danger (think ā€œfight or flight!ā€) Cortisol has slower effects that are not as obvious to track. 3ļøāƒ£ Whereas adrenaline increases the heart rate and can make you feel anxious during intense moments, cortisol has longer-term health effects related to metabolism, sleep, brain, and mood. Cortisol is so central to the stress cycle that Iā€™ll be sharing more about it and what we can do to balance it in upcoming weeks.
