DSIP, short for Delta Sleep-Inducing Peptide, is a naturally occurring neuropeptide first discovered in rabbit cerebrospinal fluid in 1974. Composed of 9 amino acids (sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) with a molecular weight of approximately 848.8 daltons, it exhibits various biological activities such as regulating sleep, calming the nerves, and maintaining physiological rhythms.

As an endogenous peptide, DSIP does not directly induce sleep. Instead, it improves sleep quality, prolongs deep sleep cycles, and exerts indirect effects on the body’s stress response and emotional regulation by influencing the balance of neurotransmitters (e.g., gamma-aminobutyric acid, serotonin) in the central nervous system.
