In nature, the superficial phenomena of many things often hide deeper secrets. For example, some plants may seem harmless, but they are actually highly toxic; Some foods look delicious but are actually harmful to health.
Similarly, some of the behaviors and products we take for granted in our daily lives may also harbor risks that we are not aware of. Today, we're going to uncover the secrets behind two seemingly healthy products, sunscreen and high-calcium milk.
Let's start with sunscreen. We all know that UV rays are very damaging to the skin, and prolonged exposure to the sun can increase the risk of skin cancer. As a result, sunscreen has become a must-have for many people when they go out in the summer. Sunscreens protect the skin from damage by helping to block or absorb UV rays through the physical or chemical sunscreens in their ingredients.
However, some recent studies have shown that the ingredients in certain sunscreens may have adverse health effects. In particular, some ingredients in chemical sunscreens, such as oxybenzone and para-aminobenzoic acid (PABA), are suspected to be potentially carcinogenic.

These chemicals are able to be absorbed by the skin, enter the blood circulation, and accumulate in the body, potentially disrupting the endocrine system and increasing the risk of cancer.
As a hypothetical example, there is a young woman who is very skin-conscious and uses sunscreen containing oxybenzone every day. After long-term use, she began to show symptoms of endocrine disorders, and after examination, it was found that the level of oxybenzone in her body was significantly high.
Doctors advised her to stop using sunscreens that contained this ingredient and switch to physical sunscreens such as titanium dioxide or zinc oxide, which are relatively safe and not easily absorbed into the skin.
Some of the chemical ingredients in sunscreen do pose health risks. Prolonged, heavy use of sunscreens containing these ingredients may increase the risk of cancer. The United States Food and Drug Administration (FDA) has conducted a risk assessment of these ingredients and recommends that consumers choose physical sunscreens that are as safe as possible.
Next, let's talk about high-calcium milk. As we all know, calcium is an important element for human bone health, especially for middle-aged and elderly people and children, supplementing enough calcium can help prevent osteoporosis and promote bone development. As a result, high-calcium milk has become the drink of choice for many families.
However, excessive calcium intake is not completely harmless. Too much calcium may lead to hypercalcemia, affect kidney function, and even increase the risk of cardiovascular disease. Especially for some people with weak kidney function, excessive calcium intake will increase the burden on the kidneys, leading to problems such as kidney stones.
Suppose there is an elderly grandmother who drinks a lot of high-calcium milk every day because she is worried about osteoporosis. However, she began to experience symptoms such as frequent urination and fatigue, and after examination, it was found that her blood calcium level was too high, resulting in impaired kidney function. Doctors advised her to reduce her intake of calcium-rich milk and to supplement calcium by eating a varied diet, such as calcium-rich vegetables and legumes.
Excessive intake of calcium can adversely affect health. Studies have shown that hypercalcemia can lead to serious problems such as kidney stones and kidney failure. The daily intake of calcium in a normal adult should be between 1,000 and 1,200 mg, and excessive intake can increase health risks. To be on the safe side, it is advisable to consume calcium through a balanced diet rather than relying on supplements such as high-calcium milk or calcium tablets.
Scientific studies have also shown that certain ingredients in sunscreen and excessive intake of high-calcium milk, while seemingly harmless in the short term, can have far-reaching health effects with long-term use and intake. Therefore, when choosing sunscreen and high-calcium milk, consumers should pay attention to the ingredient list, choose safer products, and reasonably control the amount of use and intake according to their own situation.
Let's take another example, let's say there is a middle-aged uncle, he is usually busy with work, irregular diet, and often exposed to the sun, so he will apply a lot of sunscreen every day, and at the same time, in order to supplement nutrition, he also drinks a lot of high-calcium milk every day.
As a result, he began to feel tired and unwell, and after examination, it was found that he had high levels of certain chemicals in his body and abnormal kidney function. Doctors advised him to make lifestyle changes to reduce the amount of sunscreen he used, choose sunscreen products with safer ingredients, and limit his intake of high-calcium milk.
Through these examples and data from scientific studies, we can see that sunscreen and high-calcium milk, while beneficial to health to some extent, can pose health risks if used inappropriately or in excess. When choosing and using these products, consumers should pay attention to the ingredients and amount of the products, and avoid long-term, large amounts of ingredients that may have adverse health effects.
In addition to sunscreen and high-calcium milk, there are many other seemingly healthy habits and products in our daily life, which also require us to maintain a rational and scientific attitude.
For example, some health supplements advertise their miraculous health benefits, but in reality there is not enough scientific support to support them. When choosing health care products, consumers should pay attention to the ingredients and scientific basis of the product, do not believe the advertising and avoid blindly following the trend.
Suppose there is a male white-collar worker who sees a health supplement on the Internet that claims to be able to quickly boost immunity, and decides to buy it and take it for a long time. After a few months, he did not feel a noticeable improvement in his health, but instead suffered digestive problems due to excessive intake of certain ingredients. After a doctor's examination and advice, he stopped taking this supplement and switched to strengthening his immunity through a balanced diet and regular schedule.
In view of these situations, consumers should remain rational and cautious when choosing health products. First of all, you should check the ingredients and scientific basis of the product to avoid blindly following the trend. Secondly, you should choose the right product for yourself based on your own health status and needs. Finally, one should maintain a balanced diet and a healthy lifestyle, and do not rely on a single supplement to maintain health.
All in all, many products and habits in daily life, while seemingly beneficial for health, may actually hide potential health risks. Certain chemical ingredients in sunscreens may adversely affect the skin and endocrine system, and excessive intake of high-calcium milk may lead to hypercalcemia and digestive problems. In addition, the blind use of health supplements may also pose health risks.
I hope that everyone can pay more attention to the ingredients and use methods of products in their daily lives, and maintain a rational and scientific attitude. By choosing and using healthy products wisely, combined with a balanced diet and a healthy lifestyle, we can better protect our bodies from potential health risks.
After all, a healthy body is the foundation for us to enjoy life. Through scientific selection and use of products, we can better enjoy the joy of healthy living while avoiding those hidden risks.
