Automatic summary · not editorially reviewedThe description claims two sleep patterns: high nighttime cortisol is said to keep a person wired and hinder falling asleep, while low cortisol is said to impair glycogenolysis so that at 2-3 AM epinephrine is released and wakes the person. It says a salivary adrenal index can show which pattern applies. [1]
The description says people who cannot fall asleep may have high cortisol and those who cannot stay asleep may have low cortisol, described as two different mechanisms often treated the same way. [1]
The description proposes that elevated nighttime cortisol sensitizes acetylcholine receptors in the brainstem, and that low cortisol impairs glycogenolysis so epinephrine is released at 2-3 AM and wakes the person. [1]
The description says an adrenal salivary index will show which pattern applies and mentions a 7-day free trial at a website. [1]
Claimed cortisol patterns for falling and staying asleep
According to the description, a person who cannot fall asleep should be considered as possibly having high cortisol, and a person who cannot stay asleep as possibly having low cortisol. These are described as two different mechanisms that are often treated the same way. The description does not report any study, patient group or measured data behind these statements. [1]
Proposed nighttime mechanism involving acetylcholine and epinephrine
The description proposes that elevated nighttime cortisol sensitizes acetylcholine receptors in the brainstem, keeping the patient wired. It also proposes that low cortisol impairs glycogenolysis, so that at 2-3 AM, when glucose stores deplete, the adrenal medulla releases epinephrine to compensate, and that this is what wakes them. These are proposed mechanisms in the description, not results of a reviewed study. [1]
Salivary adrenal index offered as a way to distinguish patterns
The description states that an adrenal salivary index will show which of the two patterns a person has, and it points to a 7-day free trial at a website. It gives no information on how the index is measured, how well it distinguishes the patterns or whether the proposed mechanisms have been tested. The video and transcript were not reviewed. [1]
