sleep Disorders can occur due to insufficient intake of calcium and vitamin D3. To such conclusion experts quoted by Cursorinfo.
Experts conducted a study involving about 2 million people with sleep disorders. It turned out that most spend their time indoors — they do not get the required amount of ultraviolet rays and vitamin D. Volunteers were offered treatment with vitamin D3, then most of the dream came back to normal.
To get a good nights sleep, the concentration of calcium in the body must also be OK. For this you can just drink a glass of milk before bedtime, experts believe. They suggest to include in the diet foods fortified with calcium and vitamin D3, as well as Hiking and sunbathing.
