We've all heard the phrase "high cortisol", but what does it actually mean?
Cortisol is often called the stress hormone, yet it's an essential part of keeping us healthy. It helps regulate blood sugar, supports our immune system, influences our sleep-wake cycle and gives us the energy we need to get through the day.
