Vitamin D deficiency can also cause insomnia? This is true, vitamin D supplementation needs to be done like this

The public is familiar with vitamin D. Vitamin D is also known as the sunshine vitamin. It can be synthesized in the human body through the exposure to ultraviolet rays from the sun, so it is also called a free vitamin. Vitamin D deficiency can cause rickets, affect bone health, and even cause irreversible bone damage. In fact, vitamin D deficiency is also closely related to insomnia.

Many people may have experienced insomnia. You can't fall asleep when you lie in bed at night. Even if you lie on a bed worth tens of thousands of yuan, you still toss and turn and find it difficult to fall asleep. Insomnia is related to many factors. For example, tryptophan deficiency can cause insomnia, vitamin deficiency can cause insomnia, and so on. However, the fact that vitamin D deficiency can also cause insomnia may be unfamiliar to the public.

John Reddy, a professor at Harvard Medical School, wrote in the book "What Doctors Want You to Know Most" that "scientists have found that vitamin D has a therapeutic effect on insomnia. After studying 1,500 people with various sleep disorders, it was found that the area of ​​the brain containing vitamin D receptors happens to be the area involved in sleep."

That is to say, the brain area involved in sleep is highly overlapped with the area containing vitamin D receptors in the brain. After these insomnia patients were treated with vitamin D, their insomnia was greatly improved. Another expert, Michael Holick from Boston University, also affirmed the relationship between vitamin D deficiency and insomnia.

It has become a consensus among many medical experts that vitamin D deficiency can cause insomnia. In real life, vitamin D deficiency is quite common. Night sweats, crying, and bald spots on the back of the head in infants and young children are all caused by vitamin D deficiency. Symptoms of rickets such as pigeon chest, funnel chest, and O-shaped legs in the bones are caused by severe vitamin D deficiency.

The calcium deficiency problem that the public needs is also closely related to vitamin D. Vitamin D deficiency is not only common in the United States, but also in China. Why do so many people have vitamin D deficiency, and how should we supplement vitamin D?

The reason why vitamin D deficiency occurs is closely related to the source of vitamin D. The food source of vitamin D is relatively simple, and the content in plant foods is very low. Animal foods are mainly deep-sea fish, and it is difficult for ordinary people to eat fish every day. It is difficult for ordinary people to get enough vitamin D through food.

Another important source of vitamin D is synthesis through exposure to ultraviolet rays from the sun. This pathway seems simple, but it is often difficult for many people to do it. Although the sun is bright, many people tend to be "fully armed" when they go out. Especially women, who are afraid of getting tanned. They put on sunscreen, hold a sun umbrella, wear sun-protective clothing, and wrap themselves up tightly.

This practice blocks the sun's ultraviolet rays, which affects the synthesis of vitamin D, and vitamin D deficiency is more common. If you want to supplement vitamin D, you must insist on getting sun exposure regularly. In summer, you should choose the cooler mornings and evenings, before 10 a.m. and after 4 p.m.

In winter, the temperature may be very low and many people are reluctant to go out. At this time, you can choose the dietary nutrient supplement cod liver oil to supplement vitamin D. The main components of cod liver oil are vitamin A and vitamin D. The two can play a synergistic role in the human body and promote the absorption of each other.

Vitamin D is essential, so don't forget to supplement it. Don't wait until problems arise before you remember the importance of vitamin D. By then, your body has already paid the price.
