What is Athlete’s Foot?
Athlete’s foot, also known as tinea pedis, is a fungal infection that affects the skin on the feet and toes. It is caused by a group of fungi called dermatophytes, which feed on the dead skin cells and keratin on the surface of the skin. Athlete’s foot is one of the most common types of fungal infections, affecting about 15% of the population.
Athlete’s foot can cause various symptoms, depending on the type and severity of the infection. Some of the common signs and symptoms of athlete’s foot are:
- Itching, burning, or stinging sensation on the feet or toes
- Redness, inflammation, or swelling of the skin
- Scaling, peeling, or flaking of the skin
- Cracking, splitting, or bleeding of the skin
- Blisters, sores, or ulcers on the skin
- Foul odor from the feet
Athlete’s foot can affect any part of the foot, but it usually occurs in the areas that are moist and warm, such as between the toes, on the sole, or on the sides of the foot. Athlete’s foot can also spread to other parts of the body, such as the nails, hands, groin, or scalp, if the infected skin comes in contact with these areas. This is called tinea corporis, tinea manuum, tinea cruris, or tinea capitis, respectively.
Athlete’s foot is contagious and can be transmitted from person to person through direct or indirect contact. Direct contact means touching the infected skin of another person, while indirect contact means touching objects or surfaces that have been contaminated by the fungus, such as shoes, socks, towels, mats, floors, or showers. Athlete’s foot can also be contracted from animals that have fungal infections, such as dogs or cats.
What Causes Athlete’s Foot?
Athlete’s foot is caused by a group of fungi called dermatophytes, which are naturally present on the skin of humans and animals. These fungi thrive in warm, moist, and dark environments, such as the inside of shoes, socks, or locker rooms. When the conditions are favorable, the fungi multiply and invade the outer layer of the skin, causing an infection.
Some factors that can increase the risk of developing athlete’s foot are:
- Wearing tight, closed, or synthetic shoes or socks that trap moisture and heat
- Sweating excessively or having a medical condition that causes excessive sweating, such as hyperhidrosis
- Having a weak immune system or a chronic disease, such as diabetes, HIV, or cancer
- Having a skin injury, such as a cut, scrape, or burn, that breaks the skin barrier and allows the fungus to enter
- Sharing footwear, towels, or personal items with someone who has athlete’s foot
- Walking barefoot in public places where the fungus is prevalent, such as gyms, pools, or saunas
How to Prevent Athlete’s Foot?
The best way to prevent athlete’s foot is to keep your feet clean and dry, and to avoid exposure to the fungus. Some of the preventive measures that you can take are:
- Wash your feet daily with soap and water, and dry them thoroughly, especially between the toes
- Wear breathable shoes and socks that allow air circulation and moisture evaporation
- Change your socks regularly, and wash them in hot water with bleach or antifungal detergent
- Use antifungal powder or spray on your feet and shoes to prevent fungal growth
- Wear sandals or flip-flops when walking in public places where the fungus is common, such as locker rooms, showers, or pools
- Do not share footwear, towels, or personal items with others, and disinfect any items that may have come in contact with the fungus
- Trim your toenails regularly, and keep them clean and dry
- Check your feet for any signs of infection, and seek medical attention if you notice any symptoms
How to Treat Athlete’s Foot?
Athlete’s foot can be treated with over-the-counter antifungal medications, such as creams, sprays, or powders, that are applied directly to the affected area. These medications contain active ingredients, such as clotrimazole, miconazole, terbinafine, or tolnaftate, that kill the fungus and relieve the symptoms. You should follow the instructions on the label, and use the medication for the recommended duration, usually two to four weeks, even if the symptoms improve or disappear.
Some of the over-the-counter antifungal medications that are available are:
| Product | Type | Active Ingredient |
|---|---|---|
| Lotrimin AF | Cream, Spray, Powder | Clotrimazole |
| Micatin | Cream, Spray, Powder | Miconazole |
| Lamisil AT | Cream, Spray, Gel | Terbinafine |
| Tinactin | Cream, Spray, Powder | Tolnaftate |
You can also use home remedies, such as tea tree oil, garlic, vinegar, or baking soda, to treat athlete’s foot. These remedies have antifungal and anti-inflammatory properties that can help reduce the infection and the inflammation. However, these remedies are not proven to be effective, and may cause irritation or allergic reactions in some people. Therefore, you should consult your doctor before using any home remedies, and stop using them if you experience any adverse effects.
If your symptoms are severe, persistent, or do not improve after two weeks of using over-the-counter antifungal medications, you should see a doctor for prescription medication. Your doctor may prescribe oral antifungal pills, such as fluconazole, itraconazole, or terbinafine, that can treat the infection from within. However, these pills may have side effects, such as liver damage, skin rash, or allergic reactions, and may interact with other medications that you are taking. Therefore, you should inform your doctor about your medical history, and follow the prescribed dosage and duration.
Your doctor may also prescribe topical antifungal creams, such as ketoconazole, econazole, or ciclopirox, that are stronger than the over-the-counter ones, and can treat the infection more effectively. You should apply the cream as directed by your doctor, and complete the course of treatment, even if the symptoms improve or disappear.
In some cases, your doctor may also prescribe steroid creams, such as hydrocortisone, to reduce the inflammation and itching caused by athlete’s foot. However, you should not use steroid creams alone, as they can worsen the infection by suppressing the immune system. You should use steroid creams in combination with antifungal medications, and only for a short period of time, as directed by your doctor.

Athlete’s Foot Self-Care: What You Need to Know
In the first part of this article, I explained what athlete’s foot is, what causes it, how to prevent it, and how to treat it. In this part, I will discuss some of the complications, myths, and facts about athlete’s foot. Let’s begin.
What are the Complications of Athlete’s Foot?
Athlete’s foot is usually a mild and self-limiting condition that can be cured with proper care and medication. However, in some cases, athlete’s foot can lead to complications, such as:
- Secondary bacterial infection: The cracks, blisters, or sores on the skin caused by athlete’s foot can become infected by bacteria, such as staphylococcus or streptococcus, that can cause more pain, swelling, pus, and fever. This can also increase the risk of cellulitis, a serious skin infection that can spread to the bloodstream or the lymph nodes.
- Fungal nail infection: The fungus that causes athlete’s foot can also infect the nails, causing them to become thick, brittle, discolored, and distorted. This is called onychomycosis, or tinea unguium, and can be difficult to treat. Fungal nail infection can also affect the appearance and function of the nails, and cause pain and discomfort.
- Allergic reaction: Some people may develop an allergic reaction to the fungus that causes athlete’s foot, resulting in a condition called id reaction, or dermatophytid. This can cause blisters, rashes, or hives on other parts of the body, such as the hands, arms, or chest, that are not infected by the fungus. This can also cause itching and inflammation, and may require antihistamines or steroids to treat.
- Chronic or recurrent infection: Some people may have chronic or recurrent athlete’s foot, meaning that the infection does not go away completely, or comes back frequently. This can be due to a resistant strain of fungus, a weak immune system, poor hygiene, or inadequate treatment. Chronic or recurrent athlete’s foot can cause more damage to the skin, and increase the risk of complications.
If you experience any of these complications, or if your symptoms worsen or do not improve after two weeks of treatment, you should see a doctor as soon as possible for further evaluation and management.
What are the Myths and Facts about Athlete’s Foot?
There are many myths and misconceptions about athlete’s foot that can cause confusion and misinformation. Here are some of the common myths and facts about athlete’s foot that you should know:
- Myth: Athlete’s foot only affects athletes.
- Fact: Athlete’s foot can affect anyone, regardless of their physical activity level, age, gender, or lifestyle. The name athlete’s foot comes from the fact that the infection is more common among athletes, who tend to sweat more and wear tight shoes, but anyone who is exposed to the fungus can get it.
- Myth: Athlete’s foot is harmless and does not need treatment.
- Fact: Athlete’s foot is not a serious condition, but it can cause discomfort, pain, and embarrassment. If left untreated, athlete’s foot can also lead to complications, such as bacterial infection, fungal nail infection, allergic reaction, or chronic infection. Therefore, it is important to treat athlete’s foot as soon as possible, and to follow the preventive measures to avoid recurrence.
- Myth: Athlete’s foot can be cured by home remedies, such as vinegar, garlic, or tea tree oil.
- Fact: Home remedies may have some antifungal and anti-inflammatory properties, but they are not proven to be effective or safe for treating athlete’s foot. Some home remedies may also cause irritation or allergic reactions in some people, and may interfere with the action of antifungal medications. Therefore, it is advisable to consult your doctor before using any home remedies, and to use them with caution and moderation.
- Myth: Athlete’s foot can be prevented by washing your feet with soap and water.
- Fact: Washing your feet with soap and water is a good hygiene practice, but it is not enough to prevent athlete’s foot. You also need to dry your feet thoroughly, especially between the toes, and to wear breathable shoes and socks that keep your feet dry and cool. You also need to avoid sharing footwear or towels with others, and to wear sandals or flip-flops in public places where the fungus is common.
- Myth: Athlete’s foot can be cured by over-the-counter antifungal medications alone.
- Fact: Over-the-counter antifungal medications are effective and safe for treating mild to moderate cases of athlete’s foot, but they may not work for everyone, or for every type of fungus. Some people may have a resistant strain of fungus, or a severe or complicated infection, that may require prescription medication or other treatments. Therefore, it is important to follow the instructions on the label, and to see a doctor if your symptoms do not improve or worsen after two weeks of treatment.
