Fungal skin infections are frustrating and often uncomfortable. Athlete’s foot, for example, causes a scaly, itchy rash, usually between your toes.
If you’re dealing with something like athlete’s foot, you might be wondering, “Does salt kill fungus on skin?” After all, salt is inexpensive and readily available.
This article will explore whether salt is an effective remedy for fungal skin infections, looking at both its potential benefits and its limitations.
Types of salt and how they might help with fungus
While some people swear by salt as a home remedy, it’s important to remember that fungus can be stubborn. If you have a fungal infection, it’s always best to see a doctor to find out what treatment is right for you.
Sea salt
Sea salt is full of minerals that may contribute to skin health. Some people believe it has antiseptic properties that could help with a fungal infection.
If you want to try sea salt, you can use it to make a foot soak or a paste.
Epsom salt (magnesium sulfate)
Epsom salt isn’t technically salt, but people often call it that. Some people believe it can reduce inflammation, ease athlete’s foot symptoms, exfoliate skin, and reduce odor.
A 2023 study found that Epsom salt baths may help with arthritis symptoms.
The best way to use Epsom salt is in a foot soak.
The science behind salt and fungal growth
Here’s how salt could help inhibit fungal growth:
- Osmotic pressure. Salt can draw moisture away from the skin, creating an environment where fungus is less likely to thrive.
However, salt as a fungicide on skin has its limits. For example, if you have athlete’s foot, Epsom salt won’t kill the fungus causing it.
Ultimately, while salt might play a small role, it’s not a primary treatment. Maintaining good hygiene (keeping your feet clean, dry, and aired out), including understanding if chlorine kills athlete’s foot, is way more important to prevent fungus from coming back.
Practical application: Salt soaks and other remedies
If you’re interested in trying salt soaks, here’s what to do:
How to prepare a salt soak
- Use warm water (between 92°F and 100°F).
- Add about a half-cup of Epsom salts to a foot-soaking tub.
- Soak your feet for about 15 minutes.
Combining salt with other remedies
Salt soaks can be a great addition to other treatments you’re trying.
For example, you can pair them with:
- Over-the-counter (OTC) antifungal treatments. Be sure to use the product for the recommended two to three weeks, even if your symptoms disappear.
- Tea tree oil. Rub tea tree oil into your affected skin twice each day for up to a month.
Precautions and considerations
If you have diabetes, open wounds, or very dry skin, talk with a doctor before trying a salt soak.
Also, don’t do foot soaks every day. Regular foot soaks can make your skin dry and uncomfortable.
When to seek professional medical advice
Although anecdotal evidence suggests salt water soaks may help relieve certain fungal skin infections, you should seek medical advice from a podiatrist or your family doctor if:
- Home remedies aren’t working.
- The infection is getting worse or spreading.
- You have diabetes or another underlying condition that makes treating a fungal infection more complex.
Frequently Asked Questions
How long does it take for salt to kill fungus?
There’s no definitive answer on how long it takes for salt to kill fungus on the skin, as it depends on the type and severity of the fungal infection. While salt has antifungal properties and can inhibit fungal growth, it’s not a guaranteed quick fix. Results can vary, and it might take days or weeks of consistent application to see any noticeable improvement.
Is salt good for skin fungus?
Salt can potentially help with some skin fungal infections due to its drying and antimicrobial effects. Salt can draw moisture out of fungal cells and slow their growth. Some people find soaking in saltwater or applying a salt paste beneficial, but it’s not a substitute for proven antifungal medications and may not be effective for all types of fungal infections.
What is the fastest way to cure skin fungus?
The fastest way to cure skin fungus is generally with prescription-strength topical or oral antifungal medications prescribed by a doctor. Over-the-counter antifungal creams, and other treatments, like Betadine, can also be effective for mild cases. It’s crucial to follow the prescribed treatment plan and maintain good hygiene to prevent recurrence.
Does rubbing alcohol kill fungus on skin?
Rubbing alcohol has some antifungal properties and can help kill fungus on the skin. However, it’s not as effective as dedicated antifungal medications. While it might provide temporary relief or help prevent the spread of infection, it’s best used as a supplement to, rather than a replacement for, prescribed treatments. Also, be careful as rubbing alcohol can dry out and irritate the skin.
The Bottom Line
Salt, especially Epsom salt and sea salt, may relieve some of the symptoms of fungal infections like athlete’s foot. A soak in salt water could help reduce inflammation, exfoliate your skin, and fight foot odor.
Salt treatments work best when used with other antifungal treatments and good hygiene practices. If you think you have a fungal infection, it’s always a good idea to talk to a doctor. They can help you determine the best treatment plan for your specific situation.
