Chronic Insomnia Is Associated and Hypothalamic-Pituitary-Adrenal Axis
This is a technical but interesting article on sleep disorders. The authors suggest that one type of insomnia is not insomnia at all, but rather a state of hyperarousal–the body is not yet ready to shut down. This occurs as a result of increased secretion of cortisol from the adrenal glands. This would indicate that a salivary profile for adrenocortical stress would be strongly indicated in any patients having difficulty falling asleep at night. We would also expect to see problems with estrogen/testosterone levels as the adrenals shunt precursors away from DHEA and over to production of cortisol. Nutritional intervention and exercise can be used to help bring these imbalances under control.
