When we think of does zinc help sleep, we often associate it with enhancing REM sleep – the dream phase of sleeping. But it has the potential to enhance all stages of sleep. Zinc is crucial to regulating the circadian rhythm, and thus the sleep-wake cycle, and promoting restorative non-REM sleep. It is also associated with improved memory and cognitive function. Zinc has even been shown to reduce the symptoms of obstructive sleep apnea.
The exact mechanism by which zinc promotes sleep remains largely unclear, but it is known to affect the activity of neurons in various regions of the central nervous system (CNS). Zinc concentration fluctuates across the day, with the level being lowest in the evening and highest in the morning. It is also thought to interact with the NMDA and GABA receptors, which are important for sleep regulation.

Zinc also has antioxidative properties, which can help mitigate oxidative stress that contributes to insomnia and poor sleep quality. Furthermore, zinc is essential for promoting a healthy immune system and maintaining the growth of cells. Zinc can be found naturally in several foods, including oysters, red meat, poultry, and seafood.
Although the research in this area is still limited, it’s clear that zinc has a significant role to play in promoting good sleep. This article delves into the multifaceted relationship between this trace mineral and sleep, covering topics like adenosine production, neurotransmitter modulation and oxidative stress mitigation.
