You don't need a medical degree to understand this: When you're stressed, your body releases cortisol. When cortisol is high, your body stays alert. When you can't lower cortisol, you can't sleep—no matter how tired you are. The MenoDream Pro works because heat and gentle pressure on specific facial points activate your parasympathetic nervous system, which physically lowers cortisol and signals your body to shift from "alert" to "rest." This isn't marketing pseudoscience. It's the same principle doctors use in vagus nerve therapy for anxiety and PTSD.
