What is nail fungus and how does it arise?
Nail fungus – medically known as onychomycosis – is an infection of the nails that is primarily caused by filamentous fungi (dermatophytes), less commonly by yeasts or molds. Toenails are most commonly affected, but fingernails can also show changes.
Typical conditions are humid and warm , such as those found in closed shoes or communal facilities.
Typical starting situations:
-
First signs: Discoloration or changes usually occur at the free edge of the nail.
- Nail fungus cause: A combination of fungi and humid climate – for example through sweating or walking barefoot in swimming pools.
Which types of fungi play a role?
Mushroom species |
Description |
Dermatophytes |
The most common pathogens, including Trichophyton rubrum , prefer horn material. |
Yeast fungi |
E.g. Candida albicans , often involved in fingernails. |
mold |
Usually only occurs in previously damaged nails. |
Depending on the condition of your nails, a tailored care routine may be beneficial . Nail care products from HealthRoutine can be specifically integrated into your daily routine— complemented by the new Myko-Matrix solution for targeted treatment of fungal infections.

Common triggers – these factors can play a role:
Risk factor |
Description |
Weakened defenses |
The skin is less resistant to external influences. |
diabetes |
Changes in the skin can increase susceptibility. |
Circulatory disorders |
Nails receive fewer nutrients – which makes them more vulnerable. |
Tight shoes |
Heat and humidity build up – an ideal environment for fungi. |
Wet feet |
Wearing damp socks or shoes for a long time promotes fungal growth. |
Public areas |
Swimming pools, changing rooms or saunas can be contaminated with fungal spores. |
Older age |
As we age, the structure of our nails changes. |
Familial clustering |
Some people are naturally more vulnerable. |
Particularly relevant: tight shoes and wet feet
Closed shoes without breathability trap moisture—an environment that promotes fungal growth. Make sure you wear well-ventilated footwear and regularly care for your feet.
Public places as a cause of nail fungus
Many people move barefoot in areas like swimming pools or saunas . Fungal spores can easily be transmitted there. Wear bathing shoes and make sure you dry yourself thoroughly after showering.
Signs of nail fungus – what you should look out for:
- Nail discoloration : Yellowish, brownish or whitish changes on the nail
- Thickening & deformation : The nail becomes thicker, wavy or irregular
- Brittle toenails : Nails split or break more easily
- Nail detachment : In advanced cases, the nail may partially detach from the nail bed
- Itching & pressure sensation : Especially possible around the affected tissue
