Washing hands is one of the foundations of every individual’s hygiene. Hand washing is usually associated with clean, healthy skin, but equally important is the drying of the washed hand. Therefore, it is essential to determine which type of drying is most beneficial for skin and hands.
This article focuses on the types of hand dryers currently available, their effects on the skin, viable alternatives, and myths surrounding them.
Different Types of Hand Dryers
Hand dryers come in various types, each offering distinct advantages and considerations based on speed, efficiency, and user comfort.
Hot Air Hand Dryers: Manual air blowers use hot air to remove water on the hands by either heating the hands or evaporating the water on them. These units usually run slower than newer models, with a 30 to 45-second drying time. Compared to the other types, it is far less harsh on the skin because of the moderate pressure of the air it provides; however, it is not the quickest way either.
Jet Hand Dryers: These dryers are considered the latest modern technology in hand drying. They use high-speed flights to expel water from the hands. These units are substantially faster: drying takes about 10-15 seconds. Although the process is among the most efficient, the high air pressure may irritate sensitive skin.
Impact of Hand Dryers on Skin Health
Hand dryers and skin health have an intricate connection. Therefore, one must consider how these standard devices impact the skin’s barrier and moisture.
The heat generated by dryers exposes the skin to harm that may damage the epidermis. Constant interference with high temperatures above the skin temperature generates rapid ejection of moisture and natural skin oil, interfering with protective skin functions.
This thermal stress is highly unfortunate, especially for people with diseases like eczema or dry skin.
Furthermore, it is established that high-velocity air streams may blow bacterial-contaminated bathroom air back onto the hands. Hence, they cause potential hygiene issues and result in an increase in skin sensitivity.
Instant heat coupled with air pressure helps to drive away the surface moisture very quickly, quicker than the skin’s capabilities to manage hydration.
This excessive drying can make the skin scale flaky and sensitive in cold or dry climates where the skin is already hard to moisturise.
Hygiene Concerns with Hand Dryers
Hand dryers are found chiefly mounted on the wall of public washrooms and have elicited much controversy concerning the hygiene level.
Standard hand dryers can spread germs through air circulation and may transfer common bathroom bacteria to clean hands during use.
High-velocity jet dryers are especially dangerous because their strong air currents can spray microorganisms up to 6 feet and various distances.
Studies have revealed that the bacterial count on hands is much higher when air dryers are used than when paper towels are drying.
New technologies are introducing cleaner hand-drying methods, incorporating antimicrobial features and negative ion discharge to inhibit bacterial growth.
Hand Dryers for Sensitive Skin
While using hand dryers, people with sensitive skin should be of particular concern in selecting the best product to avoid skin irritation.
Today’s advanced hand dryers are gentler on the skin and more comfortable than traditional hand-drying methods, like paper towels or older dryer models. Instead of blasting air in one spot, they spread a smooth sheet of air over the hands, drying them quickly without causing irritation.
Dermatologists have stressed the importance of temperature in treating skin sensitivity. Low temperatures reduce skin sensitivity and inflammation and preserve the integrity of the skin barrier.
Doctors recommend using hand dryers with universal non-heated airflow and maintaining a safe distance from the outlet to prevent skin irritation while drying.
Alternatives to Hand Dryers
When comparing electric hand dryers to other hand drying solutions, facilities must ensure both hygiene and sustainability while being feasible.
According to the World Health Organization, paper towels are the most efficient and recommended hand driers. They can reduce sweat to as little as 4% in 10 seconds, which makes them quite effective. However, their effectiveness is only guaranteed where proper dispensing systems are used to prevent cross-contamination of the environment on unused towels. Paper towels are more hygienic than air dryers, especially in healthcare facilities and restaurants, but their continual waste disposal impact on the environment should be considered.
Conventional hand towels can be replaced with roll-dispensed cloth towels that are both clean and environment friendly. If washed and used in single dispensing systems, they can eliminate bacteria while positively affecting the environment. Contemporary roll towel dispensers create different segments for each user, thus keeping the hygiene level high while offering fabric-like dryness.
Environmental Impact of Hand Dryers
The environmental consequences of hand-drying solutions are also considered vital factors when choosing solutions that will help organisations minimise their environmental impact.
Today’s hand dryers have improved in energy conservation compared to the past. Fast models take only 10-15 seconds to dry hands, significantly lowering energy consumption per cycle.
Although they use electricity, current technology and innovative features such as motion sensors and optimised motor designs reduce energy consumption.
Modern units are estimated to use only about 20% of the energy as older models, making them increasingly cheaper and eco-friendly.
Hand dryers also have outstanding advantages over paper solutions regarding overall environmental considerations. Their primary ecological benefits include:
No waste is produced directly during the operation
There is a low packaging requirement and transportation cost compared to a continuous supply of paper towels
Decline on the pressure of the resources of forestry
Tips for Protecting Skin
Here are some tips for protecting skin when using hand dryers:
Moisturisers should be applied when the skin is still damp. This is when the body locks in moisture and does not allow it to evaporate.
Health research shows that applying moisturisers just after washing can help minimise the occurrence of dermatitis and compromised skin barrier function.
Skincare products play a big part in hand health. The most effective hand creams contain a strategic combination of:
Glycerin and hyaluronic acid
Barrier repair substances such as shea butter and lanolin
Special oils like natural jojoba and almond oils
Common Myths and Facts
Hand dryers have been inundated by many myths and controversies encompassing hygiene and environmental sustainability. Below are two common misconceptions debunked with facts.
Myth 1: Hand dryers spread more germs than paper towels.
Fact: This is a common misconception. Modern high-velocity hand dryers with HEPA (High-Efficiency Particulate Air) filtration can match or even exceed the hygiene standards of paper towels when properly maintained.
Myth 2: Hand dryers are less eco-friendly than paper towels.
Fact: Hand dryers are a more sustainable option, significantly reducing environmental impact by eliminating the waste generated by single-use paper towels.
Conclusion
Advancements in hand-drying technology show a focus on balancing user comfort and environmental impact. While no method is perfect, modern hand dryers with efficient filters and antimicrobial coatings offer a better alternative to traditional options. Choosing the right solution depends on weighing factors like hygiene, environmental impact, and user preferences.
