Wash your hands again and again. I wash my hands often these days. If there is no toilet around, wash your hands again with a hand sanitizer. And tell her not to touch her face. This is our appearance after the spread of Corona 19.

According to a survey conducted by American research firm Discount, an adult averages 23 faces an hour and 368 faces a day. It is important to keep both hands clean.

However, the smartphone that touches the face as much as both hands doesn't care. Is the smartphone we use around the clock 24 hours a day safe?

Many people know that the surface of the smartphone we are using is 10 times more dirty than the toilet seat. However, few people wipe their smartphone surfaces from time to time. In my case, sometimes it is best to wipe the smartphone screen with pants or a cloth for cleaning glasses.

According to Scout, an adult touches a smartphone with his hands 2,617 times a day on average. People who use a lot of smartphones are said to touch and use up to 5,400 times. I think I touch my smartphone more than 4,000 times a day. In particular, it seems that the number of touches on smartphones has increased significantly as they begin to use NFC (Near Field Communication) function built into smartphones without using cash or credit cards when purchasing goods.

However, according to the World Health Organization (WHO), the SARS virus, which is the same type as the Korova19 virus, survives 36 hours on cement walls and 72 hours on plastic. Also, if you stick it on the same glass as your smartphone's LCD screen, you can survive 96 hours. It may vary depending on the room temperature, but it cannot be ignored.

In Hong Kong, studies have shown that the Corona 19 virus survived 4 days on surfaces such as bill glass and 4 to 7 days on surfaces such as plastic or stainless steel.

If the smartphone is not clean, the virus on the smartphone's surface can eventually enter our body through the eyes, mouth, and nose. In particular, if the immunity of smartphone users is reduced, this possibility increases even more, the medical staff explains.

As this Corona 19 popped, I had the habit of wiping my smartphone from time to time. If you have a hand sanitizer, you can even spray it on the LCD screen. Now it's like a habit.
So how do you manage your smartphone? Smartphone makers have asked you to follow the instructions below.

1) Disconnect all power cords and turn off the power.
2) Gently wipe the surface of the smartphone with a 70% concentration of isopropyl alcohol cotton or chlorax disinfecting tissue. (You cannot use bleach.)
3) You do not need to wipe the terminal with force.
4) Be careful not to allow detergent or water to enter the terminal connection part even with a smartphone that has a waterproof function.
5) This may not be a lot of work, but do not soak in alcohol or chlorax to clean the product effectively.

Since the surface coating of the smartphone differs depending on the manufacturer, it is important to wipe it by referring to the manual provided by each manufacturer. Complete alcohol dries so easily that it can be less effective. Therefore, it is recommended to gently wipe the surface of the smartphone with 70% to 80% isopropyl alcohol cotton or chlorax disinfecting wipes.

Often, when you buy a smartphone, you often attach a liquid crystal protective film. It is recommended to wipe the LCD screen with a soft cloth after spraying isopropyl on the smartphone screen.

It is important to wipe the smartphone LCD screen from time to time, but it is also very important to wipe both hands touching the smartphone frequently. Wiping both hands with soap and water for more than 30 seconds is standard these days.

It's not just smartphones to watch out for. Tablets, smart watches, and headphones also need care. It is also a good idea to use headphones or Bluetooth earphones during these times.
