Many women love beauty to prevent suntan
Go out on the streets armed to the teeth
Cover yourself from head to toe
And in fact,
Too much sun protection tends to deprive the body of light
This further leads to osteoporosis
Attention should be paid to
People often say that sun exposure to calcium, in fact, sun exposure is mainly to help the body get vitamin D, and vitamin D can promote calcium absorption, can help prevent osteoporosis to a certain extent.
Here's how it works: Ultraviolet light from the sun, when it hits the skin, easily converts the 7- dehydrogenated cholesterol in the skin into vitamin D3. After being absorbed into the blood, vitamin D3 undergoes liver and kidney metabolism and becomes active vitamin D. Vitamin D helps the body absorb calcium and improves calcium absorption in the gut.
So instead of calcium, it's vitamin D.
Too much sun protection increases the risk of osteoporosis
Vitamin D is one of the most important biological regulators of calcium balance in the body. The proliferation and differentiation of bone cells, the formation, maturation and calcification of bone matrix, and the reabsorption of bone are all dependent on vitamin D. Exposure to sunlight through the skin is the main source of vitamin D for humans.
The Chinese diet contains very limited vitamin D, and a large amount of vitamin D3 depends on skin exposure to ultraviolet radiation from the sun. Regular exposure to sunlight plays a key role in vitamin D production and calcium absorption. The average person gets at least 20 minutes of sunlight a day.
Sunscreen and parasols can increase the risk of osteoporosis in women. When there is not enough light outside, putting on a thick sunscreen or using a sun umbrella will affect the synthesis of vitamin D in the body.
Excessive sun protection and insufficient exposure to light can lead to vitamin D deficiency in the body. Osteomalacia is the main manifestation of vitamin D deficiency in adults. The symptoms include sore back and leg pain, mobility problems, cramping and numbness, muscle weakness, bone pain, easy to break, osteoporosis and so on.
