The Impact of Sleep Aids
Sedative medications like Ambien and Lunesta are criticized for not providing true restorative sleep, as they merely induce sedation rather than facilitating natural sleep cycles. They primarily work by activating the GABA system in the brain, but the electrical signatures of sleep on these drugs differ significantly from natural sleep. In contrast, newer medications known as DORA drugs operate by gently reducing wakefulness and promoting restorative sleep without the harsh sedative effects. These DORA drugs have been shown to increase the quantity and depth of sleep, positively impacting brain health by aiding in the clearance of Alzheimer's-related proteins like tau and beta amyloid.
