Sleep problems may be the result of vitamin D deficiency

Do you sleep badly? Or are you just not able to get enough sleep? You may be deficient in vitamin D.


Sleep problems can be the result of vitamin D deficiency


Study
Chinese researchers from Qingdao University traced 9 studies involving a total of 9,397 study participants. In those studies, the researchers had determined the quality of the participants' sleep, as well as the subjects' vitamin D levels.

Results
When the researchers put the results of these studies together, they found that a lack of vitamin D increased the risk of sleep disturbances by 50 percent compared to an adequate vitamin D status. For the calculations on which the figure below is based, the researchers used a cut off level of 20 ng/mL. That is the same as 50 nmol/L.

Anything below this level was vitamin D deficient.

Are you anxious, worried and not sleeping well? Maybe CBD will help
A supplement containing CBD, the non-psychoactive compound in cannabis, may be an alternative to pharmacological sleep aids and anxiolytics.

A warm shower in the evening improves your sleep
By improving sleep, training becomes more effective, athletes become faster, slimming attempts are more likely to succeed and the probability of a long and healthy life increases.

More sleep = less sugars in your diet
Imagine: you are a short sleeper and you normally sleep 5-7 hours a night. You are willing to boost that limited amount of sleep by changing your way of life.
