Long nails are trendy, with celebrities like Cardi B, Billie Eilish, and Mel B sporting them. However, they may be unhygienic due to the increased surface area for microorganisms to adhere to, including bacteria and fungi. These microorganisms can contribute to the spread of infections, and long nails can make it more challenging to properly wash hands and nails, potentially leading to the transmission of diseases. Healthcare workers, in particular, are advised to keep their nails short to reduce the risk of transmitting pathogens to patients. While some people enjoy the aesthetic of long nails, they can also be impractical and tedious to maintain, attracting dirt, fibres, and other particles.

Long nails can harbour more dirt and bacteria than short nails
Long nails can provide a larger surface area for microorganisms to adhere to and multiply. This means that long nails can potentially harbour more dirt and bacteria than short nails, increasing the risk of infection.
According to biology professor Jeffrey Kaplan, "The longer the nail, the more surface area there is for microorganisms to adhere". This increased surface area provides an ideal environment for the growth of dangerous microbes, including bacteria and fungi. Studies have found a variety of different bacteria and fungi underneath fingernails, with long nails providing more space for these microorganisms to thrive.
The risk of harbouring harmful pathogens increases with the length of the nail. Health experts have found that nails, whether artificial or natural, that extend beyond a certain length can pose a higher risk of carrying bacteria and pathogens. This additional length creates a favourable environment for the growth of dangerous microbes, such as methicillin-resistant Staphylococcus aureus (MRSA) and other staph bacteria.
The presence of these microorganisms can lead to potential infections, as they are difficult to remove through simple handwashing or scrubbing. This is a particular concern for healthcare workers, who are often required to maintain short nails to reduce the risk of transmitting diseases to patients. In some cases, long nails on healthcare workers have been linked to outbreaks of infections and even fatalities in neonatal intensive care units.
To maintain proper nail hygiene and minimise the risk of harbouring dirt and bacteria, it is recommended to keep nails short and trim them regularly. Additionally, scrubbing the underside of nails with soap and water or using a nail brush during handwashing can help prevent the spread of germs and nail infections.

Long nails can increase the risk of transmitting diseases
Healthcare workers are required to wear short nails due to the risk of transmitting diseases. In 1997 and 1998, two nurses at an Oklahoma City hospital may have contributed to the deaths of 16 babies due to bacteria found underneath their long nails. A similar incident occurred in 2004, where an outbreak of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae in a neonatal intensive care unit was linked to artificial nails.
Long nails can also hinder effective handwashing, as it is more difficult to scrub the underside of long nails. This can result in a higher probability of carrying microorganisms, even after handwashing or scrubbing. Studies have found a variety of different bacteria and fungi underneath fingernails, including MRSA, an antibiotic-resistant bacteria that causes serious infections.
Additionally, long nails can harbour viruses. Fingernails have been found to be reservoirs for hepatitis B, hepatitis C, and human papillomavirus. With the COVID-19 pandemic, it is important to note that nails may act as reservoirs for viruses transmitted to the oral-nasal mucosa. Therefore, it is recommended to keep nails short and emphasise cleansing the nail undersides as part of proper handwashing to prevent the spread of diseases.

Long nails can be difficult to maintain and keep clean
The increased surface area and crevices under long nails create an ideal environment for the growth of dangerous microbes. For example, studies have found 32 different types of bacteria and 28 different types of fungi underneath fingernails. This includes antibiotic-resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA), which can cause serious infections in vulnerable individuals like hospitalized patients.
Additionally, long nails can be more prone to breakage, especially for those new to the trend. This may require regular appointments with a nail technician to maintain their strength and integrity as they grow. Broken nails can also increase the risk of trapping dirt and bacteria underneath, further contributing to potential hygiene issues.
To maintain hygiene with long nails, it is crucial to prioritize regular and thorough cleaning. This includes scrubbing the underside of nails with soap and water or using a nail brush every time you wash your hands. Keeping nails trimmed and maintaining proper nail care tools, such as nail clippers and files, can also help reduce the risk of dirt and bacteria accumulation. However, it is worth noting that even with these measures, long nails may still harbor more microorganisms than short nails, making them more challenging to keep clean.

Long nails can be impractical for everyday tasks
Long nails can interfere with basic hygiene and make it challenging to keep hands and nails truly clean. They provide a larger surface area for dirt, bacteria, and other microorganisms to accumulate, which can contribute to the spread of infections. This increased surface area also makes it more difficult to thoroughly wash and scrub the hands and nails, potentially allowing harmful pathogens to remain even after washing.
The length of long nails can cause difficulties when performing tasks that require fine motor skills and precision. For example, simple actions like typing on a keyboard, using a mobile phone, or even holding cutlery can become more cumbersome and awkward with long nails. Everyday activities that require dexterity may become more challenging and time-consuming.
Long nails can also pose a safety risk in certain situations. For instance, they may hinder the ability to properly wipe oneself after using the restroom, potentially leading to inadequate hygiene. Additionally, long nails can increase the risk of accidentally scratching oneself or others, which may result in pain and injury.
The maintenance of long nails can be tedious and time-consuming. They may require more frequent appointments with a nail technician to manage their length and strength as they grow. Regular filing, trimming, and cleaning are necessary to prevent breakage and maintain their appearance. This additional upkeep can be impractical for those with busy schedules or those who are new to having long nails.
While long nails can make a fashion statement and boost one's confidence, it is essential to consider the potential impracticalities and challenges they may pose in daily life. Maintaining proper hygiene and safety practices with long nails is crucial to mitigate the risks associated with the accumulation of dirt and bacteria.

Long nails can be linked to deadly, infectious outbreaks in healthcare settings
Long nails can pose a serious health risk, especially in healthcare settings. Healthcare workers, including phlebotomists, are often required to keep their nails short to reduce the risk of contamination and infection. This is because long nails can harbour dirt, bacteria, and other pathogens, which can then be transferred to patients during medical procedures.
In the United States, guidelines for phlebotomists recommend keeping nails short for infection control. Phlebotomists are responsible for drawing blood from patients for various tests, donations, or transfusions, and they must adhere to strict guidelines to ensure patient safety. Many hospitals, clinical labs, and home healthcare agencies require phlebotomists to have short, natural nails to minimise the risk of introducing pathogens into blood samples and causing harm to patients.
The risk of infection is higher with artificial nails as they are not completely sealed, allowing for the colonisation of pathogens. Additionally, nail polish can provide pathogens with niches due to cracks in the polish or poor cleaning. Long nails can also make it more difficult to maintain proper hand hygiene, as it may hinder thorough handwashing and the use of hand sanitiser.
Several studies have found a correlation between healthcare workers' long nails and outbreaks of infections in vulnerable patients, such as infants in neonatal intensive care units (NICU). In one case, an outbreak of Pseudomonas aeruginosa in a NICU was attributed to two nurses with long and artificial nails, respectively. Another study found a link between long nails on nurses and lethal infections in 16 newborn babies in an intensive care unit. Proper hand hygiene and nail care are critical for healthcare workers, especially in high-risk settings like NICUs, to prevent the spread of infections and deadly outbreaks.
