What is NPS?
A small neuropeptide that modulates arousal, anxiety, and sleep-wake balance. It is notable in sleep research because it can influence both alertness and sleep fragmentation depending on context.
Key Benefits & Mechanisms
NPSR1 agonism
arousal modulation
anxiety-linked sleep control
Research Summary
Neuropeptide S is studied for its bidirectional effects on arousal and sleep architecture, making it relevant to insomnia and stress-related sleep disturbance. It also appears in circadian and anxiety research because it affects behavioral state control.
