Orexin Alertness
Orexin neurons stabilize daytime alertness and tie sleep-wake to metabolism—supported by morning light, movement, and consistent sleep timing.
Orexin alertness refers to orexin (hypocretin) neurons that stabilize wakefulness and coordinate arousal with metabolism. Low orexin signaling is central to narcolepsy; in everyday wellness, irregular sleep, carb crashes, and sedating evenings can dull daytime alertness without disease.
Morning light, movement, and protein-forward breakfasts support stable orexin-driven wakefulness.
