calcium is one of the most necessary nutrients for pregnant mothers during pregnancy. The sun is beneficial to the body's supplement of calcium. It is very useful for mother and treasure to keep the sun in the sun.
why can sun calcium supplement
sunlight contains three kinds of light, infrared, visible light and ultraviolet light. Ultraviolet light on the skin of the human body, can penetrate the skin surface, function in the subcutaneous dehydrocholesterol, vitamin D, vitamin D can promote the absorption of calcium in the intestine, thus helping bone growth and resistance to rickets.
without vitamin D, the body's absorption of calcium will be greatly reduced.
from the five month of pregnancy, pregnant women must drink 250 milliliters of milk, formula milk or yogurt a day, while eating calcium rich foods on the diet, such as seaweed, laver, beans, milk, shrimp skin and sesame paste. Pregnant women can also take some calcium tablets and vitamin D under the guidance of doctors, and are also good for calcium absorption.
so regular exposure to the sun is an important and economical calcium supplement for expectant mothers.
how should a mother shine in the sun
first, do not bask in the sun. Ultraviolet rays in sunlight help to synthesize vitamin D, but ultraviolet rays can not penetrate ordinary glass. Sitting in the room and basking in the glass is actually only getting the temperature of the sun, but he refuses sunlight nutrition. So expectant mothers accept sunlight as much as possible under natural conditions.
secondly, try to ensure the daily sunshine time. Expectant mothers should take the sun as a daily compulsory course. The sun should be enough, not less than 1 hours per day in winter, and less than half an hour in summer. Especially those women who work in sedentary offices or in basement rooms are more important. In addition, ultraviolet rays also have germicidal efficacy. Half an hour or so of sunlight can play a role in disinfection of skin and room air.
Third, master the best daily sun time. At 9-10 a.m. and 4-5 p.m., this is the best daily sunshine time summed up by people. In the middle of the two time of noon, the ultraviolet rays in the sunlight are too strong, and the long exposure to sunlight will damage the skin.
Fourth, pay attention to seasonality, avoid summer exposure and winter shortage. The sun also takes into account seasonal factors. If it is in summer, try to avoid exposure to sunlight and reduce sunbathing time. On the one hand, for the health of the skin, the sun's ultra strong ultraviolet rays will hurt the skin, pregnant women would have been prone to pigment precipitation, insolation will make the freckles, nevus and other colors to deepen. On the other hand, exposure to sunlight will cause rapid rise in body temperature, which may affect the normal development of the fetus and may also cause heatstroke. Therefore, in the summer, expectant mothers try to avoid direct exposure. They can enjoy scattering under the shade of trees, and dress as breathless as possible. If skin is sensitive to sunlight, you can choose sunscreen that is mainly physical sunscreen. And in winter, try to get out in the sun as much as possible.
fifth, choose the best sunscreen. Pregnant women should take off their hats and gloves when they are basking in the sun, expose their skin as far as possible, and let the sun and skin contact closely. But as pregnant women are more sensitive to UVA in the sun that can be tanned in the sun, after exposure to the sun, more pigmentation can be produced than others, such as the expansion of the original pigmented nevus, the freckles in the face, and even the pigmented nevus may become melanoma. So, when eating more and more Vc with more fruit and vegetables, pregnant women should use physical sunscreen, because it has less chemical composition, natural and unleaded, no effect on the fetus, chemical sunscreen or whitening cream is best not used, because some contain lead, chromium and other elements.
the sun children in pregnancy can grow tall,
pregnant women sun, the future child is tall, this is not a conclusion. The height and heredity of children are closely related to the nutrition supply in the course of growth and development in the future.
but the intake of calcium in pregnant women can directly affect the growth of the fetus. The teeth with calcium deficiency are easily damaged after birth and cause congenital rickets in severe cases. Therefore, pregnant women should pay attention to outdoor activities and exposure to sunlight. In particular, pregnant women in winter and spring, every day to arrange their own sun, will make a sufficient body of vitamin D, so that the fetus's bone and teeth develop more strong, to eliminate congenital rickets and dental caries factors. After
pregnancy, the requirement of calcium for pregnant women is greatly increased. The benefits of sun exposure for pregnant women are obvious. Women in pregnancy prone to bone loss, osteoporosis, in addition to frequent waists, leg pain, hand and foot numbness, leg cramps, also easily lead to pregnancy induced hypertension syndrome, even teeth will fall off. If dietary calcium and vitamin D content is insufficient or lack of sunshine, heavy calcium deficiency will be added.
