Your feet are home to a diverse community of bacteria and fungi, some of which are beneficial and help keep harmful pathogens at bay. Here’s a closer look at how the immune system interacts with your feet.
Skin barrier: The skin on your feet acts as a primary defense. It’s the first line of protection, preventing pathogens from entering the body. When the skin is intact, it’s a strong barrier against infection.
Immune cells: Beneath the skin, your feet are populated with immune cells, such as macrophages and T-cells. These cells can quickly respond to infection or injuries. If there is a cut or abrasion, these cells rush to the site to fend off any potential intruders.
Inflammatory response: if an infection does occur, your immune system triggers an inflammatory response. This process brings more immune cells to the area to combat the infection, which can sometimes lead to redness, swelling and heat - signs that your body is at work.
Nail health: your toenails can also be affected by the immune system. Fungal infections like athletes foot can occur when the when the immune response is weakened or when there’s excess water. Keeping your feet clean and dry is crucial to supporting your immune systems efforts.
Overall health: a well functioning immune system is vital for your overall health, and that includes your feet. Good nutrition, regular exercise and adequate hydration all supports the immune function.
