Hypothermia from wet feet can dampen immune defenses and may contribute to heart-related issues. A cardiologist at SM-Clinic, Anastasia Fomicheva, explains to socialbites.ca how this connection works and why it matters for people in Canada and the United States. When feet stay chilled and damp, the body’s immune response can weaken, making it easier for infections to take hold. In some cases, infections can affect the heart, leading to problems such as endocarditis and other inflammatory processes that involve the heart’s inner lining and valves.
Wet feet by themselves do not trigger heart disease. The root cause is typically a viral or bacterial infection. However, hypothermia can lower immunity, allowing the same infection to enter and spread more readily in the body. This heightened vulnerability can set the stage for infections like infective endocarditis, which are inflammatory diseases of the endocardium caused by microorganisms accumulating on heart valves. Understanding this chain helps explain why keeping feet warm matters for overall cardiovascular risk reduction.
Viral myocarditis, or inflammatory cardiomyopathy, is another potential concern. When a virus enters the body, it may damage heart muscle cells (cardiomyocytes). This can trigger a localized inflammatory response and initiate autoimmune processes that affect heart function. The result can range from mild symptoms to more serious cardiac implications, underscoring the importance of recognizing and addressing infections promptly.
Cracks in the skin and damp feet can also become entry points for fungi, leading to a local inflammatory reaction in the myocardium. Cold-induced leg vessel constriction and poor circulation can worsen chronic arterial or venous insufficiency, increasing the risk of edema and other circulatory complications. To prevent such issues, it is sensible to keep feet warm, dry, and well cared for, especially during colder months or in wet conditions. Taking simple precautions helps support overall heart health and reduces the likelihood of complication in at-risk individuals.
In summary, while wet feet do not directly cause heart attacks, they contribute to a cycle where infection and immune suppression raise cardiovascular risk. Staying warm, protecting the skin, and seeking medical advice when symptoms arise are prudent steps to maintain heart health and immune resilience. Regular checkups and mindful attention to leg and foot health form a practical plan for reducing complications for those with existing vascular concerns or a history of heart issues.
