Throat muscle paralysis mechanism discovered
Obstructive sleep apnea (OSA) occurs when the throat closes too much during sleep. And when we dream, the throat (as well as other muscles) close the most, as the brain temporarily "paralyzes" our muscles so we don't act out the dreams we are having. This article discusses research showing how the brain paralyzes the throat muscles when we dream, which could lead to OSA. This is exciting (at least to me) and has implications for future medical treatments for OSA.
