Sleep disturbances

Stagnated or even reduced performance

Reduced testosterone

Belly fat

Weak immune system

Increased risk of injury

Cortisol is a hormone released by the adrenal glands in response to stress, including physical exertion during sports. It plays a key role in regulating energy by breaking down protein, fat and carbohydrates to fuel your body.

However, excessive cortisol secretion during intense or prolonged exercise can negatively impact recovery. High cortisol levels interfere with the sleep cycle, leading to poor-quality rest, which is critical for muscle repair and recovery.
