In winter, many people like to bask in the sun. When winter comes, there are always many people putting a pot of blooming flowers at home. Some people also like to bask in the sun to supplement calcium. However, many people think that sun-sucking and supplementing calcium is better. Actually, this is a misunderstanding. Today we will see if sunbathing in winter can supplement calcium.

1. What is the main reason for restoring calcium when basking in the sun in winter?

Why does sun-sucking can supplement calcium? This is mainly because the active vitamin D in the human skin can promote the body to absorb calcium, so it will have the effect of calcium supplementation. We all know that there are many hair cells on the surface of human skin, which protect the skin from ultraviolet rays.

However, if ultraviolet rays are absorbed by the skin, they will also cause the human body to produce a substance called active vitamin D. Active vitamin D can promote the synthesis and utilization of vitamin D in the human body, so if we bask in the sun in winter, we can also supplement active vitamin D.

2. The harm of calcium supplementation in sunbathing

Everyone knows that the ultraviolet rays in sunlight are harmful to our bodies. For example, sun-sucking calcium will cause many enzymes in the body to become inactive and make our cells unable to synthesize calcium normally. And it can make the skin very dry, causing itching.

In addition, after sun exposure, vitamin A and vitamin D in the skin will be reduced or even disappear. Vitamin A and vitamin D are both important in the process of converting into DHA and EPA in our body. Once these vitamins are metabolized, we will cause vitamin D deficiency and even osteoporosis . And they can also cause calcium malabsorption and lead to osteoporosis.

3. How to prevent osteoporosis in winter?

If you want to prevent osteoporosis, you must first learn how to prevent osteoporosis. Many people may say that drinking some milk yourself can replenish calcium, but in fact it is not possible.

If you drink milk frequently, then your body will lose serious calcium, and you will even rarely supplement calcium, because milk has a lot of calcium and contains some lactose intolerance. The calcium content in milk is low. If you want to supplement calcium after drinking milk, then you can only drink milk, so it is necessary to pay attention to drinking milk.

In addition, you must pay attention to a balanced diet in daily life. If you often eat foods with higher sugar content in your daily life, then for you, sugar may be converted into fat and stored in your body.

This will increase your risk of osteoporosis. If you often eat foods that are high in sugar or high in salt, it will increase your risk of osteoporosis.
