New Study Shows No Link
Without testing, the idea seems to have merit. Unfortunately, the first study really looking at the subject shows it’s most likely not true.
For this study, researchers looked at about 2800 men with an average age of 76. Despite their age and possible sleep apnea, they were all in generally good health. Researchers then compared vitamin D levels and sleep apnea incidence or severity.
Initially, it seemed that there might be a link because men with the lowest vitamin D levels had the highest risk of sleep apnea. But when they crossed the results with known sleep apnea risk factors, such as obesity and neck circumference, they found that there was not enough evidence to suggest that vitamin D shortage actually increases sleep apnea risk.
Researchers noted that the lack of outdoor activity among obese elderly men might contribute to both sleep apnea and low vitamin D.
Other Vitamin Deficiencies That Affect Sleep
It’s not only a vitamin D deficiency that can contribute to sleep apnea and sleep quality or quantity. There are a few other vitamin deficiencies that can also affect your sleep. One of the best ways to find out if you have a deficiency is to take a blood test. The blood test will tell you if you have a deficiency and your doctor will instruct you on which types of supplements to take.
