Hand Dryer Side Effect: Excessive use of hand dryer can not only dry your hands but also spread bacteria and harm your health.

Hand Dryer Side Effect: You wash your hands in the washroom of a mall, office or restaurant and the shiny hand dryer on the wall in front attracts you. You press the button, a blast of hot air comes and your hands dry in a few seconds. How convenient, right? But have you ever thought that this hand dryer is not only drying your hands, but is it also harming your health?
Hand dryers and bacteria
The warm air of a hand dryer may make you feel fresh, but in reality that air can be full of bacteria. Many researches have found that the amount of bacteria on hands dried with a hand dryer is much more than on hands dried with tissue paper.
Which diseases pose an increased risk?
skin infection
Repeated exposure to bacteria-laden air can cause irritation, itching or rashes on the skin of the hands, which is especially harmful for people with sensitive skin.
gastrointestinal infection
If the bacteria on the hands come in contact with food or face, it can cause diarrhea, vomiting or stomach infection.
Respiratory illnesses
The dust and germs present in the air of the hand dryer spread in the air, which can worsen the condition of people suffering from asthma or allergies.
Risk of viral infection
Viruses spread quickly in closed spaces like washrooms. Hand dryers can prove helpful in spreading the infection by spreading these viruses in the air.
Why is excessive use dangerous?
Hot air repeatedly strips the skin of its moisture, leaving hands dry and cracked.
More bacteria are left on hands than on tissue paper.
Continued exposure can impact the immune system.
Hand dryers do provide convenience, but they can also be a gateway for invisible germs. With a little awareness and caution, you can protect yourself and your family from many diseases. The next time you go to the washroom and see a hand dryer, think once, are your dry hands really clean?
