Sleep isn’t that exciting. I mean, it’s basically lying still and unaware in a dark room for an extended period of time. But to an insomniac, it’s a blissful and often unachievable Nirvana-like state. And if you’re an older adult, then there’s a fifty percent chance that you have insomnia.
Sleep is so very important. It helps us focus, keeps us in alert and in good spirits, sharpens our reaction times, affects our hormones and our immune systems. Tired people are less productive at work, grumpy and accident prone. Sleeplessness also increases the risk of depression.
Fortunately, there is a lots of good evidence that magnesium can help people sleep and sleep well. For example, there was that 2012 study, that found that magnesium supplementation was able to lower cortisol concentrations. Cortisol, of course, is commonly known as the stress hormone. That’s probably why insomnia sufferers who supplemented with magnesium were able to improve the quality of their ZZZs.

Supplementation of magnesium appears to improve subjective measures of insomnia such as ISI score, sleep efficiency, sleep time and sleep onset latency, early morning awakening, and likewise, insomnia objective measures such as concentration of serum renin, melatonin, and serum cortisol, in elderly people.
And in 2009, a report called “Effects of trace element nutrition on sleep patterns in adult women” found that both calcium and magnesium taken together were effective at alleviating sleep problems…

…because one of the main symptoms of magnesium deficiency is insomnia and that a high-magnesium diet had been associated with a deeper, uninterrupted sleep. And calcium helped the brain create melatonin known for its ability to summon the sandman.
So if your midday catnaps have been catnap-napped, it’s time to consider magnesium supplementation!
