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

"Bed sheets, pillowcases and other bedding and underwear are the biggest breeding grounds for dust mites," said a member of the Health Management Society. "It is recommended to use hot water above 45 degrees Celsius for washing." The director of the relevant dermatology department 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, they should be dried promptly or dried in the sun to achieve the sterilization effect. For optimal antibacterial effect, you can also add diluted bleach.

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

According to experts in infectious disease research, if you want to completely kill germs, you just need to allow the disinfectant and the germs to have sufficient contact time. Otherwise, bacteria that are harmful to the human body, such as Salmonella and parasites, are likely to survive. If you rinse it off immediately after spraying disinfectant, it will not have any sterilization effect at all. General disinfectants need to stay on for at least 2 to 3 minutes.

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

A pair of unwashed hands contains approximately 800,000 germs. A study reported on an American website 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.

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

Researchers from the Institute of Drugs said that the formula of hand sanitizer is mostly alkaline ingredients, which also contain 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

Because the sweat, heat and dandruff discharged by the human body provide a suitable growth environment for microorganisms such as mites, bacteria and fungi, our clothes need to be washed even if they are only worn once. Don't throw dirty clothes together with clean clothes.

6 feet: How high the water splashes when you flush the toilet

A clinical microbiology expert from a British affiliated hospital 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.
