Scientific research is increasingly linking sleep quality with nutritional intake. A study published in 2019 found that people who get fewer than seven hours of sleep per night on average consume lower amounts of vitamins A, D, and B1, as well as magnesium, niacin, calcium, zinc, and phosphorus. The lead author of the study says the findings suggest that individuals with short sleep duration might benefit from improving their intake of these micronutrients through diet and supplementation.
The possibility that vitamin D deficiency is associated with a higher risk of sleep disorders is supported by several studies. A meta-analysis published in 2018 examined 9 studies involving 9,397 participants and found that serum levels of vitamin D were inversely associated with the risk of sleep problems. Other evidence similarly suggests that low serum levels of the mineral calcium may disrupt sleep-wake control and rest-activity rhythm, even if they are within the normal range. Calcium requires sufficient levels of vitamin D in order to be properly absorbed into the body.
