Consequences of vitamin D deficiency
Increased cancer risk
Studies have shown that breast cancer is also strongly associated with vitamin D deficiency. A 40 year study in the United States found that vitamin D supplementation can reduce the risk of breast cancer, ovarian cancer and colon cancer by half a day. Sunbathing is the best way to safely supplement vitamin D. The survey found that people in sunny areas have higher vitamin D levels and lower risk of cancer.
So, if you have nothing to do, go out and bask in the sun. Your skin is also eager to have close contact with the sun!
Cause cardiovascular burden
The study found that the risk of stroke and heart disease was 78% and 45% higher in those with low blood vitamin D levels than in those with normal levels.
A study of middle-aged and elderly people in Beijing and Shanghai shows that the risk of metabolic syndrome can be increased by 50% in the group with the lowest concentration of 25 hydroxyvitamin D compared with the group with the highest concentration. Exposure to solar energy can make the skin produce vitamin D, wake up a large number of "biological inert" substances hidden in the skin, and release nitric oxide complexes that can stretch blood vessels, reduce blood pressure and improve circulation, which is of great benefit to maintaining the health of heart and blood vessels.
In addition, lack of vitamin D may lead to muscle weakness, depression, diabetes, skin diseases and so on. So you realize the seriousness of the matter.
Affect bone health
Medical information network learned that when it comes to strong bones, many people think of calcium supplement for the first time, but in fact, vitamin D also plays an indispensable role in maintaining bone health. On the one hand, vitamin D promotes the absorption of calcium by the human body. When there is enough vitamin D in the body, the absorption rate of calcium in the diet can reach 30% ~ 40%. Without the help of vitamin D, calcium can not be effectively absorbed.
On the other hand, vitamin D can also act directly on bones and promote healthy bone metabolism. In addition, vitamin D can also regulate neuromuscular function and enhance immune mechanism.
Of course, the solution is also very simple, that is to get a good sun.
In winter, you can bask in the sun from 10 a.m. to 2 p.m;
In summer, the ultraviolet ray is strong. It is more recommended to choose the time before 10 a.m. and after 4 p.m. to bask in the sun to avoid heatstroke and sunburn.
It is recommended to dry for at least 15 minutes twice a week. Due to the reduced ability of synthesizing vitamin D in the elderly, it can be extended for a while.
