You have a second heart – and it lives in your calves.
Your body has a hidden circulatory booster, and it’s located in your lower legs. It’s called the soleus muscle, and it acts like a “second heart,” pumping blood from your legs back up toward your chest. This helps your actual heart overcome gravity and keep circulation flowing.
But here’s the important part: this second heart only works when you move.
If you sit or stand still for too long, blood can start to pool in your legs. Over time, this can lead to swelling, varicose veins, or even serious blood clots, according to experts at the Cleveland Clinic and Mayo Clinic.
The solution is simple: keep moving. A short walk every hour is enough to activate your calf pump. Even small actions like standing up, stretching, or doing toe raises can help. If you’re dealing with chronic swelling, elevating your legs or using compression socks can provide relief – but consistent movement is the real key.
Even more interesting? Some scientists are exploring how soleus-focused movements (like seated heel raises) can help regulate blood sugar and improve metabolism – meaning this second heart might have benefits beyond circulation.
So whether you’re pacing the room or just lifting your heels at your desk, remember: you’re not just moving your legs – you’re keeping your second heart beating strong.
