Seven must-know common sense for healthy living

In daily life, we must pay attention to small details. Some details are often "good helpers" for our health. In addition to having good habits of cleanliness, we must also master the correct methods, which is more beneficial to our health. Let’s take a look at some tips for maintaining a healthy lifestyle in daily life.

2~3 minutes: How long the disinfectant needs to stay

If you rinse it off immediately after spraying the disinfectant, it will not have a sterilizing effect. Robert Olinstein, an infectious disease research expert at the Mayo Clinic in the United States, said that disinfectants need to have sufficient contact time with pathogens, otherwise salmonella and parasites are likely to survive. General disinfectants need to stay on for at least 2 to 3 minutes.

45℃~65℃: The best water temperature for washing clothes and household items such as bed sheets and quilts

"Bed sheets, pillowcases and other bedding as well as underwear are the biggest breeding grounds for dust mites," said Xu Wei, a member of the Heilongjiang Health Management Society. "It is recommended to use hot water above 45 degrees Celsius for washing." Dr. Zou Xianbiao, director of the Department of Dermatology at the First Affiliated Hospital of the General Hospital of the People's Liberation Army (304 Hospital), added that when machine washing, the water temperature should be controlled between 54 degrees Celsius and 66 degrees Celsius, and wash for 15 to 20 minutes. After washing, the clothes should be dried in time or dried in the sun to achieve the sterilization effect. For optimal antibacterial effect, you can also add diluted bleach.

20 seconds: The time to wash your hands and rub them

A pair of unwashed hands contains approximately 800,000 germs. A study reported by the American website "WebMD" found that many people do not pay enough attention to hand washing, which gives bacteria an opportunity to spread. It is recommended to wash hands after coughing, sneezing, touching pets, going to the toilet, and before eating. It is best to use warm water, apply soap and rub for at least 20 seconds, rubbing the surface of your hands and every gap, and then rinse them clean.

6 feet (about 1.83 meters): The height of the water splashing when flushing the toilet

Professor Mark Wilcox, a clinical microbiologist at the University Hospital of Leeds in the UK, said that if the toilet lid is not closed when flushing, more than 50 water droplets will splash out each time, carrying bacteria in the feces and floating in the air for up to 90 minutes, which greatly increases the chance of cross-infection.

18 million: The total number of colonies per square centimeter in kitchen drains

People usually pay attention to the hygiene of kitchen knives, chopping boards, and stoves, but if the sewer is not clean, the harm should not be underestimated. Li Hongzhu said that some of the oil and residue in the sink will stick to the wall of the sewer pipe, creating conditions for the reproduction of pathogens and producing odor. These harmful gases are transmitted into the room with the air, causing nausea and dizziness, and are also prone to cause diarrhea, food poisoning and other diseases. It is recommended to clean the sewer pipes with disinfectant twice a week and remove residues in the sink in time.

15 seconds: How long it takes to rinse after using hand sanitizer

Li Hongzhu, an associate researcher at the Tianjin Institute of Pharmaceutical Research, said that the formula of hand sanitizer is mostly alkaline ingredients, including surfactants. If they are not rinsed thoroughly, these substances will remain on the hands, which will not only be harmful to the human body, but over time, the bacteria on the skin will also become "drug-resistant". Therefore, rinse with running water for at least 15 seconds after using hand sanitizer.

1-1 million: The number of microorganisms per square centimeter on people's clothes

These include pathogenic bacteria such as Staphylococcus aureus. Since the heat, sweat and dandruff emitted by the human body can provide a suitable growth environment for many microorganisms such as bacteria, fungi and mites, clothes should be washed even if they are only worn once. Do not hang dirty clothes in the closet or put them together with clean clothes.
