with the continuous improvement of our living standards, healthy health preservation has become something we advocate. Although life is limited, we have never given up the infinite longing for longevity. Do you know what the password for longevity is? In fact, changing some small habits in our life will also make us live longer. The following small series will take you to understand which seven numbers can keep you away from the danger of life loss!
45 ℃ ~ 65 ℃: the best water temperature for washing clothes, bed sheets, quilt covers and other household products
“bed sheets, pillowcases and other bedding and personal clothes are the largest breeding places for dust mites,” said the member of the health management society. “It is recommended to wash with hot water above 45 ℃.” The director of the relevant dermatology department added that during machine washing, the water temperature should be controlled between 54 ℃ and 66 ℃ for 15 ~ 20 minutes. After washing, it should be dried in time or dried in the sun in order to achieve the effect of sterilization. In order to have the best antibacterial effect, diluted bleach can also be added.
2~3 minutes: the time required for disinfectants to stay is
. According to experts from infectious diseases research, we want to kill the germs thoroughly, so long as there is sufficient contact time between disinfectants and pathogens, otherwise Salmonella, parasites and other harmful bacteria will probably survive. If you just spray disinfectant and rinse it immediately, it won’t have the effect of sterilization at all. General disinfectants need to stay for at least 2 ~ 3 minutes.
20s: time for hand washing and rubbing
a pair of unwashed hands have about 800000 bacteria. A study reported on the US website found that many people do not pay enough attention to hand washing, which gives an opportunity to spread bacteria. It is recommended to wash hands after coughing, sneezing, touching pets, going to the toilet and before eating. It’s best to use warm water, rub it for at least 20 seconds after making soap, rub the surface of both hands and all gaps, and then rinse it.
15 seconds: time to rinse after using hand sanitizer
researchers of the Institute of Medicine said that most of the formula of hand sanitizer is alkaline, which also contains surfactants. If not washed clean, these substances will remain in the hands, which is not only harmful to the human body, but also the bacteria on the skin will be “resistant” over time. Therefore, wash with running water for at least 15 seconds after using hand sanitizer.
10 ~ 1 million: the number of microorganisms per square centimeter of people’s clothes
because the sweat discharged by the human body, the heat emitted by the human body and dander will provide a suitable growth environment for microorganisms such as mites, bacteria and fungi. Therefore, even if our clothes are only worn once, they need to be cleaned. Don’t throw dirty clothes and clean clothes together.
6 feet: the height of water splashing when flushing the toilet
British affiliated hospital clinical microbiology experts said that if the toilet is not covered, more than 50 water droplets will be splashed each time, carrying bacteria splashing in feces and floating in the air for 90 minutes, which greatly increases the probability of cross infection.
18 million: the total number of colonies per square centimeter in the kitchen sewer is
. People usually pay attention to the hygiene of kitchen knives, cutting boards and stoves, but if the sewer is not clean, the harm can not be underestimated. Li Hongzhu said that part of the oil and residue in the sink will stick to the sewer pipe wall, creating conditions for the reproduction of bacteria and producing peculiar smell. These harmful gases spread indoors with the air, causing nausea and dizziness, and easily causing diarrhea, food poisoning and other diseases. It is recommended to clean the sewer pipe with disinfectant twice a week and remove the residue in the sink in time.
