Cortisol is your ‘stress hormone’, often referred to as the ‘flight or fight’ hormone or the body’s ‘built-in alarm system’. Most cells in our body have cortisol receptors, meaning cortisol can affect almost EVERY system in your body. It works with certain parts of your brain that control mood, motivation, and fear. It also regulates many processes in your body, including affecting the balance of other hormones like testosterone, human growth hormone, estrogen, and melatonin.
