Hospital staff with artificial nails spread more infections
Good hand hygiene is essential to prevent the spread of diseases and infections. Nails, in particular, can be a haven for bacteria and other germs, leading to major health issues such as bacterial and viral infections.
Artificial nails have become a popular trend, with many healthcare workers sporting them. However, there is a growing body of research that suggests that hospital staff with artificial nails spread more infections.
Several studies have reported the presence of nosocomial pathogens on artificial nails. These pathogens can cause hospital-acquired infections (HAIs), which significantly increase morbidity and mortality rates. Research has shown that the colony counts of bacteria and fungi are higher on artificial nails than on natural nails, even after handwashing. This is due to the moisture that becomes trapped between the natural nail and the artificial nail, leading to fungal growth. As a result, artificial nails have been linked to outbreaks of infections such as Pseudomonas aeruginosa and Candida osteomyelitis.
To prevent the spread of nosocomial infections, proper hand and surface cleaning are essential. Many hospitals and health care centers have implemented guidelines prohibiting artificial nails for healthcare workers. These guidelines are supported by clinical studies and are considered a top priority in infection control.

Natural nails should be kept short and clean
Keeping natural nails short and clean is an important aspect of personal hygiene. Nails can harbour bacteria and germs, which can lead to infections and other health issues. Therefore, maintaining good nail hygiene is essential, especially for those who eat with their hands.
To keep natural nails short and clean, it is recommended to trim and file them regularly. This helps maintain steady and strong nail growth. Nails should be filed in one direction using a multi-sided nail file, and a glass or steel file can be used to smooth the edges and prevent snagging. It is also important to check nails daily and keep them at a short, manageable length.
In addition to trimming and filing, proper hand and nail washing techniques are crucial. When washing hands, ensure that soap and water get under the nails, paying close attention to the fingertips and nails. Using antibacterial soaps or alcohol-based hand sanitizers can effectively reduce bacteria on the nails and fingertips. It is also recommended to use a soft washcloth or a nail brush to clean hard-to-reach areas under the nails. However, nail brushes should be washed and air-dried to prevent the accumulation of bacteria.
Practising good nail care also involves taking care of the cuticles. Pushing back and trimming cuticles can help maintain healthy nails. Additionally, using cuticle oil can nourish the nails and promote healthy growth. It is important to minimise the use of harsh chemicals on the nails and opt for more natural products. A well-balanced diet, including protein, grains, and good fats, can also contribute to strong and healthy natural nails.

Nails should be trimmed with clippers, not bitten
Maintaining good nail hygiene is essential for preventing bacterial and viral infections. Nails can become a haven for bacteria and germs if not properly cared for, which can lead to health issues such as pinworms, gastrointestinal diseases, and respiratory problems. Therefore, it is important to keep nails trimmed and clean.
Trimming nails with clippers or scissors is a safe and effective way to maintain nail hygiene. Clippers are widely available, simple to use, and can be used to achieve evenly trimmed nails. It is recommended to cut nails straight across and then use a nail file to smooth and shape them. Soaking nails in lukewarm water before trimming can make them softer and easier to cut. To ensure proper hygiene, it is important to disinfect nail tools regularly and avoid sharing them with others.
Biting nails is not a recommended way to trim them. Nail biting can harm the nail bed and increase the risk of bacterial infections. Additionally, it can lead to the peeling of keratin layers and immediate entry of bacteria into the mouth. Instead of biting, it is advised to use clippers or scissors to trim nails and maintain good hand hygiene by regularly washing hands and cleaning under the nails.
Maintaining nail hygiene in a hospital setting is crucial for both patients and medical staff. Proper nail care can help prevent the spread of infections and maintain a clean and safe environment. While nail brushes and picks may not be necessary for those with clean hands, they can be beneficial for individuals with visibly soiled hands, such as those working with soil, grease, or motor oil. Overall, good nail hygiene, including trimming nails with clippers or scissors and practicing proper handwashing techniques, is essential for maintaining personal health and preventing the transmission of diseases.

Nail brushes are not proven to improve hand cleanliness
Hand hygiene is an important aspect of personal hygiene and preventing the spread of diseases. Nails, especially longer fingernails, can trap dirt, grease, oil, and bacteria, contributing to the development of infections. Therefore, it is essential to keep nails clean and short.
Nail brushes are simple handheld devices with stiff bristles designed to clean the hard-to-reach areas under the fingernails and around the cuticles. They are often used alongside handwashing to ensure thorough cleanliness. While some people believe that nail brushes help get their nails super clean, there is limited scientific evidence to support this claim.
A study published in the Journal of Hospital Infection found no significant difference in hand cleanliness between individuals who used nail brushes or nail picks during handwashing and those who did not. This study focused on participants performing surgical scrubs, so it is possible that nail brushes could be more beneficial for individuals with visibly soiled hands.
Additionally, nail brushes themselves can become breeding grounds for bacteria if not cleaned and dried properly. This is particularly true in damp environments like handwashing stations, where bacteria can survive and proliferate on nail brushes. As a result, some health departments and inspectors have advised against the use of shared nail brushes in foodservice establishments.
To maintain hand and nail hygiene, it is recommended to keep nails short and wash them periodically with soap and water, paying attention to the undersides of the nails. Using antibacterial soaps or alcohol-based hand sanitizers can also help reduce bacteria on the fingertips and prevent the spread of infections.

Hand and nail hygiene prevent bacterial and viral infections
Hand and nail hygiene is an important aspect of personal hygiene. Nails protect the ends of our fingers and toes from injury and make it easier to pick things up. However, they can also harbour bacteria and other germs, becoming a breeding ground for infections if not properly cared for.
The nail unit is the most commonly affected area in hand infections, which can be a primary infection or a superinfection complicating other nail or skin disorders. Trauma, mechanical or chemical, usually triggers the infiltration of infectious organisms. Artificial nails and nail polish are also possible causes of bacterial infection, as they can harbour microorganisms. In severe acute bacterial infections, surgical intervention is often required to prevent morbidity and disability. Abscesses must be drained, but some viral infections, such as herpetic whitlow, require non-operative treatment.
To maintain good nail hygiene and prevent bacterial and viral infections, it is recommended to keep nails short and trim them periodically. This is because longer nails tend to collect more dirt and bacteria, promoting the spread of illness. It is also important to wash your hands regularly with soap and water, ensuring that you get underneath the nails. Using antibacterial soaps or alcohol-based hand sanitizers can be effective in reducing bacteria on the fingertips. Additionally, it is advisable to dry your hands thoroughly after washing.
In the context of preventing the spread of COVID-19, proper nail grooming practices are essential. Nails should be kept short, and the undersides should be cleaned as part of handwashing. While the relationship between nail length and viral load requires further investigation, fingernails have been found to harbour viruses such as hepatitis B, hepatitis C, and human papillomavirus. Therefore, maintaining good nail hygiene is crucial in preventing the transmission of diseases, including bacterial and viral infections.
