Description
DSIP improves sleep, reduces stress, and has analgesic properties, making it beneficial for sleep disorders, stress management, and pain relief. (PMID: 16539679, PMID: 6145137, PMID: 1530226)
Delta Sleep-Inducing Peptide (DSIP) Research Topics:
-
Sleep Regulation:
DSIP is primarily known for its ability to induce and improve sleep by interacting with sleep-regulating systems in the brain. (PMID: 16539679) -
Stress Reduction:
It has been shown to modulate stress response and reduce stress-related symptoms, potentially by influencing cortisol levels. (PMID: 6145137) -
Pain Relief:
DSIP may have analgesic properties, contributing to pain relief in various conditions. (PMID: 1530226)
