We recently dug up another potential cause to add to the mix: magnesium deficiency. According to a study published in the Romanian Journal of Neurology, the authors determined that poor quality sleep in patients with restless leg syndrome was caused by a deficiency of magnesium.
The US Department of Agriculture’s Human Nutrition Research Center in North Dakota also confirms that magnesium helps regulate sleep and that magnesium treatment can improve sleep quality and decrease the time taken to fall asleep.
Magnesium could be worth looking into even if you don't have restless leg syndrome, then. Don't self medicate, though - speak with your doctor and see what they recommend.
Remember - natural supplements aren't always safe supplements.
