Have you ever wondered why your feet smell like cheese after a long day? Well, you're not alone. Foot odour is a common problem, and it's caused by a combination of sweat and bacteria. Our feet have more sweat glands than any other part of our bodies, and when we sweat, the warm and damp environment creates the perfect conditions for bacteria to thrive. These bacteria feed on our sweat and dead skin cells, producing waste that gives off an unpleasant odour. While it's embarrassing and uncomfortable, foot odour is usually not a sign of any underlying health issues and can be easily remedied with good hygiene and keeping your feet clean and dry.

What You'll Learn
Sweaty feet and cheese have a common stink-causing bacteria
Sweaty feet and certain cheeses share a common stink-causing bacteria. While foot odour is embarrassing and uncomfortable for many, it is a common problem. Our feet have about 250,000 sweat glands, more per square inch than any other area of the body, so it's no surprise that feet get sweaty quickly.
The sweat itself is odourless, but when it builds up, it creates an inviting environment for bacteria naturally found in the environment. These bacteria feed on our sweat and the dead skin cells and oils on our feet. As the bacteria break down, they release waste that contains stinky chemicals like those made by skunks and rotten eggs.
When people make certain types of cheese, some of the bacteria on their skin get left behind on the cheese. These bacteria start eating the cheese, and as they do so, they produce the same foul-smelling waste. This is why feet can smell like cheese—they both have the same bacteria living on them. For example, Brevibacterium linens bacteria are thought to be a primary cause of foot odour, and they also give Limburger cheese its pungent scent.
To reduce foot odour, it is important to keep your feet clean and dry. Wash your feet with mild soap and lukewarm water at least once a day, and dry them thoroughly, especially between your toes. You can also use powder to absorb the sweat that bacteria need to grow. Wearing open-toed shoes or sandals and going barefoot indoors can also help keep your feet dry. Additionally, you can apply antiperspirant or deodorant spray to your feet and try various types of antifungal and antibacterial soaps.

Sweat and bacteria produce the unpleasant odour
Your feet have about 250,000 sweat glands, more per square inch than any other area of the body, so it's no surprise that feet get sweaty quickly. When feet sweat, the skin gets wet and creates a welcoming environment for bacteria naturally found in the environment. Wearing shoes and socks traps the sweat and bacteria, making the smell worse. The bacteria multiply, feeding on the dead skin cells and oils on your feet. As the bacteria break down, they release a smelly odour.
The type of bacteria that grows on your feet, Kyetococcus sedentarius, is also found in certain cheeses, such as Limburger. This is why feet can sometimes smell like cheese—they share the same bacteria. These bacteria produce waste that contains stinky chemicals like those made by skunks and rotten eggs.
To reduce foot odour, keep your feet clean and dry. Wash your feet with mild soap and lukewarm water at least once a day. Dry them thoroughly, especially between your toes. Keep your toenails short and clean. Go barefoot at home and sleep without socks on to allow your feet to breathe and prevent sweat from being trapped against your skin. Change your socks at least once a day, or more if your feet are sweaty. Choose socks that absorb moisture, such as thick, soft socks made of natural fibres or sports socks.

Foot odour is usually not a sign of underlying illness
Foot odour, or bromodosis, is a common problem caused by a build-up of sweat and bacteria on the feet. While it can be embarrassing and uncomfortable, it is usually not a sign of an underlying illness. However, severe sweating and foot odour throughout the year could indicate hyperhidrosis, a condition characterised by excessive sweating even when one is not overheated.
The human foot has about 250,000 sweat glands, which is more per square inch than any other body part. These glands release sweat throughout the day to regulate body temperature and keep the skin moist. However, when sweat builds up on the feet, it can lead to the growth of bacteria, resulting in unpleasant odours.
The bacteria responsible for foot odour are similar to those found on certain types of cheese, such as Limburger, giving rise to the familiar "cheesy" smell. These bacteria feed on the skin and produce waste that contains stinky chemicals, similar to those found in skunk spray and rotten eggs.
While foot odour is typically not a health concern, it is important to maintain good foot hygiene to prevent it. This includes washing the feet regularly, keeping them dry, wearing clean socks, and using powder to absorb sweat. For more severe cases, a doctor may prescribe stronger antiperspirants, foot soaps, or medical treatments for excessive sweating.
In rare cases, strong foot odour in individuals with diabetes could indicate an unnoticed wound or ulcer, which requires immediate medical attention. Additionally, ingrown toenails, corns, and calluses can also contribute to foot odour and should be properly managed.

Practicing good foot hygiene helps to reduce the smell
Sweaty feet can smell like cheese due to the interaction between perspiration and bacteria that thrive in socks and shoes. This bacteria, Brevibacterium linens, is also present in some cheeses, such as Limburger, and produces a foul-smelling waste that contributes to the overall odour.
Practicing good foot hygiene can help to reduce this smell. Here are some tips to improve foot hygiene and minimise odour:
- Wash your feet regularly with warm water and soap, ensuring they are thoroughly dried, especially between the toes.
- Change your socks daily and opt for socks made from natural, moisture-wicking materials such as cotton or wool. Avoid nylon socks as these can trap sweat.
- Rotate your shoes, allowing them to air dry for at least 24 hours before wearing them again. Choose shoes made from breathable materials like leather, canvas, or mesh.
- Keep toenails clean and trimmed.
- Go barefoot when possible, especially indoors, to allow your feet to breathe and dry.
- Soak your feet in a mixture of warm water and Epsom salt, black tea, or vinegar to control sweating and eliminate bacteria.
- Apply talcum powder or antiperspirant to the soles of your feet to reduce moisture.
- For athletes or those with frequent foot odour issues, consider investing in a second pair of shoes and alternate between them.
- Wash your shoes and insoles regularly.
- Avoid walking barefoot in communal spaces to prevent the spread of fungal diseases.
Additionally, if the odour persists or is severe, consult a podiatrist or doctor for further advice and potential medical treatments.

Teenagers and pregnant women are prone to sweaty feet
Anyone can experience sweaty feet, but hormonal changes make teenagers and pregnant women particularly prone. During puberty, the body goes through significant hormonal shifts, which can cause teenagers to sweat more. Similarly, pregnant women experience frequent changes in hormone levels and the secretion of new hormones, which can trigger hot flashes and excessive sweating. This tends to occur during the first and third trimesters and diminishes or resolves after giving birth as hormone levels stabilise.
Additionally, the extra weight gained during pregnancy can make physical activities more strenuous, causing the body to overheat and sweat more. The metabolic activity required to support fetal growth also raises the core body temperature, leading to increased perspiration. Moreover, pregnant women often retain more fluids, and the body may try to expel this excess fluid through sweating.
The sweat itself is odourless, but when it soaks into shoes and doesn't dry before wearing them again, bacteria start to break down the sweat, releasing a cheesy odour as it decomposes. This is similar to the process that occurs in some cheeses, where bacteria feed on the cheese, producing a foul-smelling waste that contributes to the overall odour.
To prevent and treat sweaty feet, it is important to keep the feet clean and dry. This includes washing and drying the feet daily, changing socks at least once a day, and ensuring shoes are dry before wearing them again. Cotton or wool socks are recommended over nylon, and surgical spirit can help dry out the skin between the toes. Antiperspirants and deodorants can also be applied to the feet, and foot powders can be used to absorb sweat and inhibit bacterial growth.

Frequently asked questions
The billions of bacteria that live on your feet break down the sweat and produce a foul odour. This process is similar to how cheese is made, and the same bacteria that live on your feet can also be found on cheese.
To prevent your feet from smelling like cheese, keep them clean and dry. Wash your feet with mild soap and lukewarm water at least once a day, and dry them thoroughly. You should also wear fresh socks at least once a day, and use powder to absorb the sweat that bacteria need to grow.
Some other ways to reduce foot odour include going barefoot at home and when sleeping, wearing open-toed shoes or sandals when possible, using a pumice stone or foot file to remove dead skin cells, and alternating between two pairs of shoes so they can dry out for a full day before being worn again.
Foot odour is usually not a sign of an underlying health issue. However, severe sweating and foot odour could be a sign of hyperhidrosis. Additionally, while foot odour is not linked to diabetes, people with diabetes should take special care of their feet as a strong odour could be a sign of an unknown wound or ulcer.
