In the past two years of fighting against the new crown, more and more people have begun to pay attention to hand hygiene.
People often say that the hand is the dirtiest part of the human body, in fact, the mobile phone that never leaves the hand is even worse.
As the "artifact" of work, life and communication that everyone can't live without, mobile phones are inevitably subject to various pollutions throughout the day.
When we are cleaning and welcoming the new year, don't forget to take a good bath for the mobile phone.
Half of mobile phones are contaminated when answering a call
A hospital survey showed that there were 120,000 bacteria per square centimeter on the surface of 108 medical staff's mobile phones, including 39 strains of pathogenic Staphylococcus aureus.
And a study conducted among anesthesiologists found that 10% of sanitized hands were contaminated with pathogens after a minute of talking on a mobile phone.
In the opposite experiment among dental workers, 50% of the subjects were subsequently contaminated with 53% of gram-positive bacteria and 2% of gram-negative bacteria after receiving a brief call after cleaning the mobile phone. 3% are fungi.
Choose the right "body wash" for your phone
Mobile phone disinfection can use hand sanitizer, ordinary wipes and 75% ethanol, etc.
If you don't have any of these at home, you can use balsamic oil instead.
Hand sanitizer is a disinfectant with chlorhexidine gluconate and ethanol as the main active ingredients. Pathogenic bacteria, pyogenic cocci and pathogenic yeasts.
Ordinary wet wipes are composed of non-woven fabrics containing pure water and plant extracts, while disinfecting wipes can also be selected.
75% alcohol is relatively convenient to buy in daily life, and disinfectants that are less harmful to the human body are widely used in various places.
A very important point: According to the data, 75% alcohol has an inactivation effect on the new coronavirus.
There are also steps to give your phone a bath
Wash your hands before wiping the phone, wipe the phone with an attitude of "aseptic operation", remove the phone case, wipe one by one, and finally wipe the four corners and borders. Do not wipe randomly.
have to be aware of is:
After wiping the phone, wipe it dry in time. Do not let the disinfectant or alcohol penetrate into the internal parts of the phone, which will reduce the performance of the phone and damage the life of the phone.
Do not dry your phone after wiping it down.
Some friends worry that after sterilizing the mobile phone, disinfectant or alcohol will penetrate into the internal parts of the mobile phone, so it is very dangerous to put the sterilized mobile phone to dry in the sun.
When the mobile phone operates, it will generate a certain amount of heat, and exposure to the sun will cause excessive heat in the mobile phone, which will damage the life of the mobile phone.
One-time disinfection does not completely solve the sanitation problem and has no substantial effect.
After one disinfection, the phone will slowly accumulate bacteria and dirt.
Regular disinfection is king.
In addition, some people in work and life also use the method of wrapping the mobile phone with disposable plastic film to prevent the mobile phone from being polluted. This method is simple and effective.
However, it is still a good habit to clean your phone regularly.
