Although they’re located at the farthest distance from your brain, the health of your feet can give you clues about the health of your brain, mainly whether your brain is receiving enough oxygen. When circulation to the feet is poor, creating a variety of symptoms discussed below, this is a red flag circulation to the brain is compromised as well. Just because you can breathe doesn’t mean your brain is getting enough oxygen.

If your brain is not getting enough oxygen it won’t function well. You may notice brain fog, declining memory, that you tire more easily, and that it is harder to learn new things. Depression is another common symptom. Poor brain oxygen is a serious matter because it accelerates degeneration of your brain—vascular dementia from lack of blood flow to the brain is the second most common type of dementia after Alzheimer’s.

Feet symptoms that could point to problems in your brain

Cold toes and feet. If your feet and toes are colder than your ankles or calves, this means circulation is poor to your feet, and hence to your brain. It’s hard to measure your own skin temperature so have someone else compare the temperature of your calves and ankles with that of your feet and toes. If the feet and toes are colder than your ankles and calves this means your circulation to the furthermost regions of your body is compromised. Cold fingers and a cold nose are common too.

How to restore blood flow to your feet and your brain

It’s important to rule out a health condition that can cause poor blood flow to your feet, such as hypothyroidism, anemia, a heart condition, diabetes, or low blood pressure. Normal blood pressure is considered 120/80. If either number is 10 or more points below that it means blood is not getting pushed into these more distant capillaries of the feet and brain. People with low blood pressure typically also have low blood sugar (reactive hypoglycemia) and adrenal fatigue, a condition in which their stress response system is worn out.

It’s important to stabilize blood sugar by avoiding sugars and processed carbohydrates and not skipping meals. Exercise is great for increasing circulation, especially short bursts of high-intensity exercise. Also, a variety of nutritional compounds can support blood flow to your feet and your brain.
