When we get cold, our blood flows to our core to make sure the organs that are vital to our survival are kept warm and oxygenated. That means that our extremities—hands and feet—tend to suffer from bad circulation when it’s cold.
When you run, the blood flows easier because your veins dilate and your heart pumps harder. But when you’re outside in the cold, your circulation still won’t be like it usually is. That’s why running gloves are an essential item to have.
