However, this number could be reduced if women took dietary supplements.
"Our findings suggest that individuals with short sleep duration might benefit from improving their intake of these nutrients through diet and supplementation," Ikonte added.
In addition to the findings on sleep duration, the research suggested nutrients may also play a role in sleep disorders, poor sleep quality and trouble falling asleep.
Micronutrients are vitamins and minerals that our bodies require but do not produce. As a result, they must come from our diet. Globally, billions of people suffer from at least one micronutrient deficiency.
Previous studies have demonstrated important roles for micronutrients in growth and development, disease prevention and healing, and normal bodily functions, including sleep. Magnesium, for example, helps the body produce melatonin and other compounds involved in sleep. Some studies suggest zinc plays a role in sleep regulation.
"Whether chronic short sleep causes nutrient insufficiency or the nutrient insufficiency causes short sleep still needs to be determined," said Ikonte.
"A clinical study that investigates [impacts of] supplementation with these nutrients on sleep outcomes is needed to demonstrate cause and effect," Ikonte added.
