The Role of GABA and Glycine in Promoting Relaxation and Improving Sleep
GABA, also known as gamma-aminobutyric acid, is a neurotransmitter that plays a vital role in calming the brain and reducing stress levels. It has been found to have potential anti-seizure properties as well. By facilitating relaxation, GABA helps promote restful sleep and a sense of tranquility.
Glycine, on the other hand, is an amino acid and neurotransmitter that has been found to increase serotonin levels, a chemical in the brain that promotes feelings of well-being. This increase in serotonin helps improve sleep quality and duration. Initially, glycine was believed to be solely responsible for these sleep-enhancing effects. However, further research has shown that blocking both GABA and glycine neuroreceptors leads to sleep paralysis, indicating the significant role of both neurotransmitters in sleep regulation.
Connection between Hypertension and Panic Disorder
When isolated sleep paralysis (ISP) occurs without any other form of parasomnia, it can be linked to hypertension and panic disorder. In a study conducted on 31 African American men and women, it was found that approximately 42 percent of them experienced episodes of ISP. Researchers believe that excessive stress can lead to panic manifestations, which in turn cause episodic hypertension. Furthermore, the response to adrenergic stimuli can result in episodes of isolated sleep paralysis. Medical professionals also suspect that there may be specific adrenergic dysfunction related to hypertension that contributes to the development of both ISP and symptoms of panic disorder.
