Sleep health: The impact of circadian rhythms and supplements

circadian rhythm sleep hygiene melatonin magnesium supplements sleep quality

Health experts are highlighting the critical importance of sleep quality and circadian rhythm alignment. Going to bed regularly after midnight can disrupt the body's internal clock, potentially increasing the risk of cardiovascular disease, type 2 diabetes, obesity, and depression. Experts note that sleep is most effective when it follows natural hormonal cycles, specifically involving the rise of melatonin in the evening and the rise of cortisol in the early morning.

Research into sleep aids shows varying results. A 2025 study published in Nature and Science of Sleep found that while magnesium bisglycinate may slightly reduce insomnia symptoms compared to a placebo, the overall benefit for adults was considered modest. Melatonin remains a primary tool for addressing disrupted biological clocks, such as those caused by jet lag or shift work.

Furthermore, the continuity of sleep is as vital as its duration. Because sleep occurs in approximately 90-minute cycles, frequent interruptions can prevent the body from completing essential restorative processes, such as tissue repair and memory processing, which primarily occur during deep sleep in the first half of the night.
