I. Core: Regulating Deep Sleep
1. Specifically enhance δ slow-wave deep sleep
Electroencephalogram (EEG) confirms that it can strengthen the δ waves in the brain and prolong the duration of the most restorative slow-wave sleep; it does not suppress REM (Rapid Eye Movement) rapid eye movement sleep, which is different from sleeping pills (which often disrupt dream sleep).
2. Shorten the sleep onset latency
For people with insomnia, using it before bedtime can reduce the average sleep onset time by about 20 minutes, alleviating problems such as difficulty falling asleep and waking up frequently during the night.
3. Restore disrupted circadian rhythm
Applicable to shift workers, time zone differences, and those with long-term sleep deprivation. It resets the sleep cycle; it does not cause daytime drowsiness (with an appropriate dose), and has no sedative-like drug hangover sensation.
4. Improve sleep quality and deepen restorative rest
Deep sleep is responsible for tissue repair, the secretion of growth hormone, and the removal of metabolic waste from the brain. DSIP directly strengthens this stage.
II. Regulating Stress and Cortisol (HPA Axis Homeostasis)
1. Inhibit cortisol elevated by stress
Long-term high pressure, overtraining, and anxiety can cause elevated cortisol levels at night, leading to insomnia; under the action of DSIP, the hypothalamus-pituitary-adrenal (HPA) axis is stabilized, reducing nighttime cortisol levels, and alleviating stress-related insomnia.
2. Anti-anxiety, soothe sympathetic excitation
Upregulate GABA inhibitory neurotransmitters, reduce excessive excitation of glutamate, provide mild sedation, and reduce anxiety and worry; animal experiments show potential anti-depression potential.
3. Enhance stress tolerance, reduce burnout fatigue
It belongs to an adaptation protopeptide. Under long-term stress, it reduces mental exhaustion and chronic daytime fatigue.
III. Endocrine Hormone Regulation (Recovery and Anti-Aging Related)
1. Promote nocturnal growth hormone (GH) secretion
Deep sleep is the peak period for GH release. Under the action of DSIP, the duration of slow-wave sleep is prolonged, indirectly enhancing GH; it helps with muscle repair, fat loss, skin and tissue repair, and post-exercise recovery.
2. Regulate luteinizing hormone (LH)
Assist in the balance of the auxiliary gonadotropin, improving endocrine disorders caused by stress and decreased libido.
3. Stabilize ACTH (adrenocorticotropic hormone) stress hormone fluctuations
Avoid drastic fluctuations in hormones causing emotional, sleep, and blood pressure fluctuations.
IV. Analgesia, Chronic Pain
1. Synergistic analgesia through the endogenous opioid pathway
Combined with δ opioid receptors， it increases the pain threshold， alleviates chronic nerve pain， muscle strain pain， and stress-related somatic pain.
2. Assist in withdrawal reactions
Used in studies for opioid and alcohol withdrawal， reducing insomnia， restlessness， and discomfort from physical pain.
V. Neuroprotection and Antioxidation
1. Protect against cerebral ischemia， reduce neuronal apoptosis
In animal models of cerebral infarction， DSIP reduces cerebral ischemic damage， shrinks the infarction area， and inhibits oxidative stress damage to brain cells under stress.
2. Antioxidation， reduce brain oxidative damage
Clear free radicals， alleviate neuroaging damage caused by long-term stress and staying up late； potential research direction for neurodegenerative protection.
3. Stabilize blood pressure and heart rate
Prevent abnormal increase in blood pressure and heart rate under stress， moderately regulate cardiovascular homeostasis.
VI. Assist in exercise recovery， immune enhancement
1. Accelerate recovery after high-intensity training
Deep sleep + GH dual support， reduces delayed muscle soreness， and reduces overtraining syndrome.
2. Indirectly enhance immunity
Deep sleep is a key period for immune cell proliferation， improving immune resistance after improving sleep.
