Sleep & Stress

Sleep and stress research investigates the interconnected neurological and hormonal systems responsible for circadian rhythm, sleep architecture, stress adaptation, relaxation and neuroendocrine regulation.

Sleep is controlled by interactions between circadian timing systems and homeostatic sleep pressure. Researchers examine neurotransmitters, neuropeptides and hormonal signals involved in transitions between wakefulness, non-REM sleep and REM sleep.

Stress physiology is similarly complex. The hypothalamic-pituitary-adrenal axis coordinates the release of hormones including cortisol in response to physical and psychological stress. Scientists investigate how prolonged changes in these systems may influence sleep, cognition, metabolism and immune signalling.

Certain peptides have been investigated experimentally for their relationship with sleep architecture or stress-related neurological signalling. DSIP, Selank and other research compounds, for example, have historically attracted scientific interest in these areas, although the strength and quality of evidence varies considerably.

Contemporary research also examines the bidirectional relationship between sleep and metabolic health. Poor sleep can influence appetite, glucose regulation and hormonal signalling, while metabolic and psychological factors can affect sleep quality.

The Peptide Research Sleep & Stress category brings together compounds associated with these areas of neuroscience and neuroendocrine investigation.

These products are research compounds only and are not intended to diagnose or treat insomnia, anxiety, stress disorders or other medical conditions.
