Human beings are covered in fungus. Yes, it sounds a bit gross, but our bodies are brimming with all sorts of fungi, ranging from the beneficial microorganisms that help balance our skin biome to the harmful types that can lead to infections and systemic disease.
These microscopic organisms can travel not only on our bodies but in the air, on clothing, in soil, and in food and water. In fact, research reveals that our skin’s surface harbors several different kinds of fungi. You’d think our hands would be the obvious “home” for multiple fungus types since—as tactile beings—we are always touching things. However, while they’re loaded with bacteria, the hands actually have relatively low fungi levels.
The feet are another story. As many fungal conditions occur on the body in areas that trap a lot of moisture or often incur friction, this should come as no surprise. About a decade ago, US National Institutes of Health researchers conducted a fungi census on a group of healthy test subjects.
Using DNA from samples collected via cotton swabs and toenail clippings, they found a whopping 80 different types of fungi on the feet (the heels, webbed skin between the toes, and toenails The scientists even found , the yeast used to brewbeer!
