| Melatonin and Sleep | The reduction of opioid activity is the result of over-activity in the sympathetic nervous system (SNS) (,). | 3 | Zafari Zangeneh Farideh (2022) | Deregulated Brain’s Central Clock Management on Sleep-Wake Behavior in Women With Polycystic Ovary Syndrome: Melatonin & Sleep Pattern |
| Melatonin and Sleep | Therefore, the action of melatonin in the brain centers is similar to its action in the tissue, which is associated with positive and negative feedback (). | 3 | Zafari Zangeneh Farideh (2022) | Deregulated Brain’s Central Clock Management on Sleep-Wake Behavior in Women With Polycystic Ovary Syndrome: Melatonin & Sleep Pattern |
| Melatonin and Sleep | REM sleep with a short duration is associated with the augmented sympathetic tone, whereas NREM duration is longer and has the opposite role. | 3 | Zafari Zangeneh Farideh (2022) | Deregulated Brain’s Central Clock Management on Sleep-Wake Behavior in Women With Polycystic Ovary Syndrome: Melatonin & Sleep Pattern |
| Melatonin and Sleep | 1 2 3 4 5 6 7 Circadian rhythms are cycles of 24-hour physiological and behavioral functions which are synchronized with environmental cycles, like sleep-wake. | 3 | Zafari Zangeneh Farideh (2022) | Deregulated Brain’s Central Clock Management on Sleep-Wake Behavior in Women With Polycystic Ovary Syndrome: Melatonin & Sleep Pattern |
| Melatonin and Sleep | Failure to meet the recommended 7-9 hours of restful sleep per night is known to increase the risk of several health conditions, reason why regular and adequate sleep should be seen as a priority instead of an unnecessary commodity easily traded as required by the commitments of our busy lives. | 4 | Conti F (2026) | Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review. |
| Melatonin and Sleep | While both the quantity and the quality of sleep can be largely improved with relatively straightforward practices dictated by good sleep hygiene, emerging research suggests that dietary and supplementation protocols focused on certain foods, nutrients, and biochemical compounds with sleep-promoting properties can act as subsidiary sleep aids in complementing these behavioral changes. | 4 | Conti F (2026) | Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review. |
| Melatonin and Sleep | The scope of this narrative review is to summarize the available evidence on the potential benefits of selected nutraceuticals in the context of circadian rhythm and sleep disturbances, namely melatonin, magnesium, omega-3 fatty acids, tart cherry juice, kiwifruit, apigenin, valerian root, L-theanine, glycine, ashwagandha, myoinositol, Rhodiola rosea, and phosphatidylserine. | 4 | Conti F (2026) | Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review. |
| Melatonin and Sleep | Humans spend approximately one third of their life asleep but, as counterintuitive as it may sound, sleep is far from being a quiet state of inactivity. | 4 | Conti F (2026) | Dietary Protocols to Promote and Improve Restful Sleep: A Narrative Review. |
