Do you know when Global Handwashing Day is after washing your hands for so many years?

It's today, October 15th!

Some people may say, 'Hand washing is all, is it necessary to set up a special holiday?'?

Introduction to Hunan Disease Control and Prevention: Although washing hands may seem like a small matter, there is a "university question".

Hand washing is the simplest, most economical, and effective way to prevent infectious diseases

You must not know how many microorganisms there are in a pair of unwashed hands!

Hunan disease control introduction: Hand washing is the first step to remove bacteria, viruses, and other microorganisms from your hands, and is the simplest, economical, and effective method to prevent infectious diseases.

Research has shown that proper hand washing can reduce the occurrence of gastrointestinal diseases such as diarrhea and respiratory diseases such as influenza. Frequent hand washing by mothers can reduce the risk of neonatal death by 44%.

Seven step washing technique, using a hand dryer

Washing hands is an action that everyone repeats N times a day. After the COVID-19, the popularity and awareness of the importance of hand washing have greatly improved, and everyone has gradually become familiar with the seven step washing technique - the first step is to rub the palm to the palm; Step 2, cross your fingers and rub the palm against the back of the palm; Step three, cross your fingers and rub your palms together; Step 4: Hold hands together and rub the backs of your fingers together; Step 5: Rotate and rub your thumb in your palm; Step 6: Rub your fingertips in the palm of your hand; Step 7, rotate and rub the wrist until it reaches the elbow.

After washing hands, it is the drying process. In recent years, "hand dryers" have gradually become the "divine tools" for hygiene and cleaning equipment. However, Hunan Disease Control and Prevention pointed out that some problems with hand dryers are also worth paying attention to.

In theory, using a hand dryer prevents human hands from being contaminated by pathogenic microorganisms again due to contact with public facilities. This not only achieves the goal of rapid hand drying, but also meets the hygiene requirements of preventing bacterial cross infection. However, in recent years, some scholars at home and abroad have believed that the use of hand dryers may cause secondary pollution to indoor air and hand hygiene. They not only found that when the hand dryer is turned on, the total number of bacteria, fungi, and inhalable particles in the air directly below the nozzle are significantly higher than when it is not turned on, but also found that the total number of bacteria and inhalable particles in the air about 50cm away from the nozzle are also higher than when it is not turned on.

Although the 'artifact' fell onto the altar, there is still a legend about it in the Jianghu. It is a pity to abandon such a convenient and environmentally friendly device in daily life.

Hunan Disease Control reminds that during the use of hand dryers, regular cleaning and disinfection of machine components (such as daily cleaning and disinfection), timely replacement of filter screens, and ensuring good hygiene of hand dryers are necessary. At the same time, strengthening indoor cleaning work in the restroom, improving ventilation and ventilation facilities, and maintaining good air quality can still play its due role.
