The principle of sunshine for calcium

April 1, 2023
For the summer, the sun is not welcome, while the winter sun is a great thing in life, that can be calcium can also drive the cold to keep warm. However, where does the sunshine calcium come from, do you know? The following follow me to popularize it.

Not calcium, but to promote the synthesis of VD

UV rays from sunlight can promote the production of pro-vitamin D3 from 7-dehydrocholesterol in the skin, which is converted into vitamin D3 in relying on skin temperature, and vitamin D3 is absorbed into the blood by lymphatic transit, and then generated into active vitamin D by the action of hydroxylase in the liver and kidney.

VD promotes the absorption of calcium substances

Active vitamin D can promote the absorption of calcium and phosphorus in the intestine, which can effectively prevent osteomalacia and rickets in children. For the elderly, children, pregnant women are very beneficial, so there are many people follow the motto "rather be a yellow-faced woman, not a soft-legged shrimp". So the sun does not directly replenish calcium, he can only help the body to produce vitamin D that can promote the absorption of calcium substances.

Infrared light accelerates the absorption and utilization of calcium and phosphorus

In addition to vitamin D, which can promote the absorption of calcium, the infrared rays in the sunlight can also promote the metabolic absorption of calcium, phosphorus and other substances. When the body temperature rises, blood vessels expand, blood flow is accelerated, the metabolic system will run faster, and the body's absorption and utilization of calcium and phosphorus substances will be more efficient.

Warm tips

The winter sun is always warm, ultraviolet intensity is not as strong as the summer, afraid of tanning beauty can dare to let the skin bathe in the sun. Not only can indirectly replenish calcium, but also make your body warm Oh! (Note: Winter sunbathing is best controlled at about one hour, not more than two hours, to avoid dizziness and physical discomfort.)
