Orexins: Exploring Their Influence on Sleep

Why do I snore

Orexins, also known as hypocretins, are neuropeptides that play a crucial role in regulating arousal, wakefulness, and appetite. Their discovery has significantly advanced our understanding of sleep mechanisms and disorders. These neuropeptides are primarily produced in the hypothalamus, a brain region essential for various functions, including sleep regulation.

Research indicates that orexins help maintain wakefulness. When orexin levels are low, as seen in conditions like narcolepsy, individuals may experience excessive daytime sleepiness and sudden sleep attacks. Conversely, higher levels of orexins are associated with alertness and the prevention of sleep disturbances.

Interestingly, orexins have also been linked to stress responses. The release of these neuropeptides can increase in stressful situations, suggesting their role in the body’s fight-or-flight response. This dual function of promoting wakefulness while also responding to stress highlights the complex nature of sleep regulation.
