In life, there are many habits and behaviors that seem hygienic but are actually unhygienic, which are very detrimental to health, but most people do not pay enough attention to them. Using white paper or newspaper to wrap food
Some people, even some food shops, like to use white paper to wrap food. A piece of white paper seems spotlessly clean, but in fact, in the production process, many bleaches and corrosive chemical raw materials are added. Although the pulp is washed and filtered, it still contains many chemical components that can contaminate food. As for using newspaper to wrap food, it is even more inadvisable because many inks or other toxic substances are used in printing, which are extremely harmful to the human body. Using liquor to disinfect bowls and chopsticks
Some people often use white liquor to wipe bowls and chopsticks, thinking that this can achieve the purpose of disinfection. What they don't know is that the alcohol concentration for disinfection in medicine is 75°, while the alcohol content of ordinary liquor is below 56°. Therefore, wiping bowls and chopsticks with liquor cannot achieve the purpose of disinfection at all. Using toilet paper to wipe tableware, fruits, or faces
Laboratory tests have shown that many types of toilet paper (especially those sold on the streets and produced by unregular manufacturers) are not well disinfected. Due to incomplete disinfection, they contain a large number of bacteria. Even if well disinfected, they become contaminated during the storage process. Using such toilet paper to wipe bowls, chopsticks, or fruits will not clean the items; on the contrary, it will bring more bacteria to the food during the wiping process. Using a towel to dry tableware or fruits
People often think that tap water is raw water and is unhygienic. Therefore, after washing tableware or fruits with tap water, they often use a towel to dry them. This may seem hygienic and meticulous, but it is actually the opposite. Dry towels often harbor many germs. At present, most tap water in our cities has undergone strict disinfection treatment. Food washed with tap water is basically clean and can be used with confidence, without the need to be wiped dry with a dry towel. Boiling spoiled food before eating
Some housewives boil spoiled food at high temperatures and pressure before eating it, thinking that this can completely eliminate bacteria. However, medical evidence shows that the toxins secreted by bacteria before entering the human body are very heat-resistant and not easily destroyed or decomposed. Therefore, this method of using heat and pressure to treat leftover food is not worth promoting. Cutting off the rotten part of fruit and eating the rest
When eating fruit, some people find that a part of it is rotten, so they cut off the rotten part and eat the rest, thinking that this is hygienic. However, experts in microbiology believe that even if the rotten part of the fruit is cut off, the remaining part has already been contaminated with bacterial metabolites through the fruit juice, and even microorganisms have begun to multiply. The mold in it can cause mutations in human cells and lead to cancer. Therefore, if a fruit is even partially rotten, it should not be eaten; it is better to throw it away. Long-term use of the same type of medicinal toothpaste
Medicinal toothpaste has a certain inhibitory effect on some bacteria, but if you use the same type of medicinal toothpaste for a long time, the bacteria in the mouth will slowly adapt and develop drug resistance, which means the medicinal toothpaste becomes ineffective. Therefore, in our daily lives, we should change our toothpaste regularly. Hanging towels on used fluorescent light tubes
Fluorescent light tubes contain toxic substances such as mercury, fluorescent powder, and a small amount of ammonia. Some families use used fluorescent light tubes to dry towels and handkerchiefs, thinking they are clean and hygienic. What they don't know is that in a damp condition, if the ends of the tube are eroded or the tube itself has small cracks, various harmful substances inside will gradually seep out. Especially when the temperature is high, more mercury will seep out, contaminating the towels and handkerchiefs and harming human health. If these harmful substances directly enter the human eyes, they can cause vision loss or even blindness. Therefore, used fluorescent light tubes should be disposed of promptly and not kept for other uses.
