Vitamin D and Sleeping Disorders

A good night’s sleep is what anyone would ask for after a hectic day at work.

But lately, are you tired of not getting enough of sleep?

Is your sound sleep is being hampered unnecessarily?

Tried adapting several solutions to make you feel comfortable, but sigh, none of them work right?

It’s been past 2pm and you are still awake, wide-eyed as an owl?

When you don’t have a good sleep, there are several other worse conditions that follow later on. Feeling very tired, drowsy, weak, not being able to pay attention or concentrate at work and irritation will follow naturally. This might affect your work and your relations.

Vitamin D deficiencies are one of the possible causes as suggested by many studies that are responsible for causing sleep disorders. And to rectify such situation of vitamin D -related sleep disorder, one has to be careful about the intake of vitamin D. Vitamin D supplementation should be carried out only under medical supervision.

It comes as a shock that more than half of the world population is deficient in vitamin D. Their Vitamin D levels are significantly low. This is a major problem because sleep disorders are an epidemic due to vitamin D deficiency. This hurts the amount of sleep you get, the quality of your sleep, and your mood upon waking up.

A new study evaluating the effect of nutrient intake and deficiencies on sleep has found that vitamin D relates to sleep maintenance. Research on vitamin D and sleep disorders is scarce and has yet to establish a causal link. The few studies on vitamin D and sleep suggest a link between vitamin D and certain sleep disorders, such as sleep apnea. However, research in general shows that sleep is related to nutrient intake and behaviour. Previous research suggests that sleep disorders, resulting in low sleep quality, can impact the nutrient intake of individuals.


Researchers recently used data from the National Health and Nutrition Examination Survey (NHANES) to help explain what effect nutrient intake has on sleep quality and sleep symptoms. NHANES is a program designed to assess the health and nutrition of the people living in the United States. It consists of a survey sent out periodically to large segments of the United States population. The researchers used data from 2007 and 2008 from NHANES to collect information on self-reported sleep quality, sleep symptoms, and nutrient intake. The researchers found that nutrient intake was most related to difficulty falling asleep and difficulty maintaining a full night’s sleep.

For vitamin D, the results showed that intake was related to the ability to maintain a full night’s sleep.


While the researchers didn’t have data on the amount of vitamin D intake, higher intake was significantly associated with a 16% reduced risk for experiencing difficulty maintaining a full night’s sleep. “Results from these nationally representative data indicate that sleep symptoms are associated with some dietary components,” the research team concluded. “Vitamin D was associated with less difficulty maintaining sleep.”

The researchers call for longitudinal studies and experimental trials to determine how long-term nutrient status and intake affect sleep.

Trials using supplementation of vitamin D will explain further how vitamin D affects sleep maintenance and overall sleep quality.
