Women’s sun exposure has the benefit of treating osteoporosis and preventing osteoporosis. Women’s demand for calcium is relatively large, mainly because women will lead to rapid calcium loss after middle and old age. This is especially true after menopause when estrogen levels drop, which eventually leads to a rapid loss of calcium and ultimately leads to osteoporosis. The benefit of more sunlight is that it can convert vitamin D3 into active vitamin D3 as much as possible, which can increase the retention of calcium, thus promoting the deposition of calcium on the bone and thus delaying or avoiding the production of osteoporosis. If you suffer from osteoporosis, you can also reduce the degree of osteoporosis by getting more sunlight.
