According to James Wilson in his book Adrenal Fatigue: The 21st Century Stress Syndrome,
“The adrenals are known as ‘the glands of stress. It is their job to enable your body to deal with stress from every possible source, ranging from injury and disease to work and relationship problems. Your resiliency, energy, endurance and your very life all depend on their proper functioning.”
When the adrenal glands are overworked, they lead to hormonal imbalances and reduce cortisol levels.
It is actually a dysfunction between the brain and adrenal glands, that are located atop the kidneys and produce cortisol and sex hormones. In a state of a healthy balance, a person sleeps well, has a stable energy during the entire day, has a good sex drive, a normal body weight, and fast metabolism.
