Nail fungus, or onychomycosis, is a common infection caused by microorganisms that invade the fingernail or toenail bed. It occurs when fungi that are normally present on the body overgrow, causing an infection. This happens when the nail provides a suitably warm and moist environment for the fungi to thrive. Walking barefoot in warm, moist areas, such as pool decks or locker rooms, increases the risk of contracting nail fungus. Additionally, frequent moisture on the hands or feet, as well as age, health, and lifestyle factors, can contribute to the spread of nail fungus.

What You'll Learn
Walking barefoot in moist areas, like pools or locker rooms
Walking barefoot in moist areas, like pools, locker rooms, or communal showers, can increase the risk of contracting a fungal nail infection. This is because fungi thrive in warm, dark, and moist environments, and these areas provide the perfect conditions for their growth.
Fungal nail infections occur when fungi attack the fingernail, toenail, or the skin under the nail, called the nail bed. Toenails are more commonly affected than fingernails due to the warm and moist environment created by shoes. Additionally, toes have less blood flow than fingers, making it harder for the body to detect and prevent an infection.
When walking barefoot in moist areas, you may come into contact with fungal spores that can infect your nails. The warm and moist environment created by shoes worn after walking barefoot can then provide an ideal setting for the fungus to flourish.
To prevent fungal nail infections, it is recommended to avoid going barefoot in these areas. Instead, wear shoes or flip-flops to create a barrier between your skin and any potential fungal spores. Additionally, keeping your nails short and trimmed straight across can make it harder for fungi to take hold.
It is important to note that fungal nail infections can be challenging to treat and often require prescription antifungal medications. Therefore, taking preventive measures, such as wearing appropriate footwear in moist areas, is crucial to reduce the risk of infection.

Skin-to-skin contact with someone who has a fungal infection
Skin-to-skin contact is one of the ways in which nail fungus can spread. Fungi are normally present on and in the body, but when they overgrow, they can cause infections. These infections can spread from one person to another through direct skin-to-skin contact and via towels, clothing, socks, shoes, nail clippers, and moist surfaces.
Fungal nail infections can also spread from one nail to your other nails and skin. The fungi that cause athlete's foot can infect the nails. These fungi often live harmlessly on the skin, but they can multiply and lead to infections. The fungi prefer warm, dark, and moist places like the feet. Toenails are more likely to be affected than fingernails because fungi thrive in dark, warm places, and the toes have less blood flow, making it harder for the body to detect and prevent an infection.
To prevent the spread of nail fungus, it is important to take steps such as keeping your nails well-trimmed and clean, avoiding walking barefoot in places where fungal infections can spread easily, such as communal showers, locker rooms, and gyms, and not sharing personal care items like nail clippers or scissors with others.
If you have a fungal nail infection, it is important to seek treatment to prevent it from spreading to others. Treatment options include antifungal creams, medicated nail lacquers, oral antifungals, and laser therapies. Prescription-strength oral antifungal medications are the fastest and most effective proven treatments for nail fungus.

Frequently wet hands or feet throughout the day
Having frequently wet hands or feet throughout the day can increase your risk of developing a fungal nail infection. This is because fungi thrive in warm, moist environments, and the area under nails that are frequently wet provides an ideal place for them to grow.
Fungal nail infections occur when fungi enter through small cracks in the nail or the nearby skin. Toenails are more susceptible to infection than fingernails because fungi thrive in dark, warm places, and the toes have less blood flow, making it harder for the body to detect and prevent an infection.
If you have wet hands frequently, wearing rubber gloves can help prevent fungal infections. This is especially important if your hands will be wet for an extended period. Keeping your hands and feet clean by washing them often with soap and water can also help prevent infections.
Fungal nail infections usually start with mild symptoms, such as white or yellow spots under the nail, and can progress to more severe symptoms, including nail thickening, brittleness, crumbling, and discolouration. In severe cases, the nail may need to be removed to allow a healthy new one to grow in its place.

Yeast and bacteria can also cause nail infections
Fingernail fungus is caused by microorganisms that invade the fingernail or toenail. Fungi thrive in dark, warm, and moist environments, making toenails more susceptible to infection than fingernails. However, yeast and bacteria can also cause nail infections, known as paronychia.
Paronychia is a common nail infection that usually results from bacterial invasion, most commonly the Staphylococcus aureus bacteria. The bacteria enter the skin through cuts, broken skin, or hangnails near the cuticle and nail fold, causing an infection. The cuticle is the skin at the base of the nail, and the nail fold is where the skin and nail meet.
Anyone can get a bacterial nail infection, but certain factors increase the risk. These include frequent exposure to irritants like detergents and chemicals, which can irritate the skin and lead to a nail bed infection. Additionally, certain medications, such as retinoids, anti-cancer drugs, HIV medications, and specific antibiotics, can increase susceptibility to paronychia.
The symptoms of paronychia include abnormal nail growth, with ridges or waves, and discolouration, such as a yellow or green appearance. The nail may become dry and brittle, and in severe cases, it can detach from the nail bed and fall off. Treatment for paronychia typically involves antibiotics to kill the infection. In some instances, pus may need to be drained, and further analysis of the fluid can help identify the specific bacteria causing the infection.
While bacterial infections are a common cause of paronychia, yeast infections can also contribute to this condition. Candida, a type of yeast, is known to cause toenail fungal infections, leading to greenish-black discolouration, known as green nail syndrome. Treatment for yeast infections typically involves oral antifungals, such as fluconazole.

Age, health, and lifestyle can increase the risk of nail fungus
Age is a significant factor in the development of nail fungus. Older adults tend to be more susceptible to fungal nail infections due to decreased blood circulation and slower-growing nails. As we age, our nails become drier and more brittle, creating tiny cracks that provide an entry point for fungi. Additionally, the reduced blood flow to the extremities impairs our immune system's ability to detect and fight off infections, making older individuals more vulnerable to nail fungus and other infections.
Underlying health conditions can also increase the risk of nail fungus. Individuals with diabetes, for example, experience circulatory problems and nerve damage, which can lead to reduced sensation in the feet. This lack of sensation makes it easier for a fungal infection to go unnoticed and untreated, potentially leading to more severe complications. A weakened immune system, whether due to certain medical conditions or medications, also increases susceptibility to nail fungus since the body's ability to fight off infections is compromised.
Lifestyle factors play a crucial role in the development of nail fungus. Those who frequently engage in activities that expose their nails to warmth, moisture, and trauma are at higher risk. For example, swimmers and runners often experience moist nails and minor nail injuries, creating an ideal environment for fungal growth. Additionally, individuals who work in wet or humid environments, such as dishwashers or cleaners, are more susceptible due to constant nail exposure to moisture.
Poor foot hygiene and the sharing of personal care items can also contribute to the spread of nail fungus. Not drying the feet thoroughly after washing, especially between the toes, provides a favorable environment for fungi to thrive. Additionally, sharing nail clippers, towels, or shoes with an infected person can transfer the fungus directly to others. Maintaining good foot hygiene practices, including regularly trimming and cleaning nails, wearing breathable footwear, and avoiding walking barefoot in public areas, can help reduce the risk of nail fungus.
Certain nail conditions, such as nail psoriasis or previous injury to the nail bed, can make individuals more susceptible to nail fungus. Damaged nail beds may provide an entry point for fungi, increasing the risk of infection. Additionally, individuals with nail psoriasis, a condition that causes nail abnormalities, are at higher risk due to the disruption of the nail's protective barrier.
Overall, understanding the risk factors associated with age, health, and lifestyle can help individuals take preventive measures to reduce the likelihood of developing nail fungus. Good hygiene practices, regular nail care, and prompt treatment of any underlying conditions are essential to maintaining healthy nails and reducing the risk of fungal nail infections.
