Lack of vitamin D causes drowsiness

There is a direct link between increased daytime sleepiness and a shortage in the body of vitamin D. This is the conclusion drawn by researchers from the State University of Louisiana in the United States.

Study author Dr. David McCarthy stresses that does not attempt to find the causes of such a link. He wanted to confirm obtained during previous studies evidence that insufficient vitamin D   in the body can be a cause or a consequence of excessive daytime sleepiness   directly or indirectly by chronic pain.

"We found a significant correlation between   Vitamin D   and sleepiness , And this relationship was much more complex than previously assumed - says Dr. McCarthy. - It is important to conduct follow-up observations to clearly establish what is cause and what is effect. This will give an opportunity to improve current therapies. "

The study involved 81 patients the clinic for the treatment of sleep disorders, who complained of sleep problems and nonspecific pain. All patients were eventually diagnosed sleep disorder caused by, in most cases, become obstructive sleep apnea. Vitamin D levels were measured by a blood test, and sleepiness scale Epworth Sleepiness Scale.

In the published journal Journal of Clinical Sleep Medicine study suggests that the higher the level of the patients turned out to have daytime sleepiness, the lower the fixed level of vitamin D.
