Orexin Blockers: A New Insomnia Approach

Most sleep aids try to "force" your brain to sleep, but what if we just turned off the signal

that keeps you awake? Traditional hypnotics usually work by amping up your brain's "off" switches,

but the latest science is focused on the orexin system. Orexin—also called hypocretin—is a

neuropeptide in your hypothalamus that acts as a "wake stabilizer" to keep you alert.

Newer drugs, known as orexin receptor antagonists, work by specifically blocking these wake-promoting

signals. This represents a massive shift in medicine: instead of sedating the

wakefulness. Research shows this can improve sleep continuity and total sleep time for those
