InsomniaIf you struggle to fall asleep at night more than three times per week, and the challenge has been going on for at least one month, then you might have one of the most common sleep disorders: insomnia. The neurobiology of insomnia isn't fully understood, and several theories seek to explain the phenomenon, which appears to be at least partially influenced by genetics. One proposes that insomnia may be a disorder of hypervigilance or hyperarousal experienced throughout the day—this sort of state occurs when a person attempts to be constantly aware of any threats, leaving them tense, anxious, and easily startled. Another suggests the disorder stems from an issue with the sleep-wake cycle controlled by one's circadian rhythm. There's no one-size-fits-all cure for insomnia, though interventions typically begin by improving sleep hygiene, encouraging people to adjust their sleep habits and presleep behaviors to better prioritize rest and relaxation.Explore Insomnia
