Fact: The temperature of blood inside the human body is consistently warmer than the rest of the body, averaging around 100.4°F (38°C). So, to answer the common question, **is your blood warm or cold?** The answer for humans is unequivocally warm, a testament to the intricate system of thermoregulation that keeps you active and alive.

While the term 'cold-blooded' suggests an animal has literally cold blood, it's a scientific misconception. The reality behind **what does having cold blood do?** is far more complex and involves an animal's reliance on external heat sources, a survival strategy known as ectothermy.

The term "cold-blooded" is a common misnomer that creates a misleading picture of animal biology. In reality, being cold-blooded does not mean that an animal's blood is perpetually cold, but rather that its body temperature is regulated by external sources, such as sunlight or warm rocks.

The vast majority of animals on Earth are 'cold-blooded,' or ectothermic. As mammals, humans are fundamentally warm-blooded, or endothermic, and therefore, it is biologically impossible for us to be cold-blooded. Our bodies are designed to maintain a consistent internal temperature regardless of the external environment. This article will delve into the science behind this physiological certainty.

The phrase “blood runs cold” is a common idiom for fear or shock, but biologically, humans are warm-blooded and maintain a consistent core body temperature. When you ask, “How do I know if my blood is cold?” you are likely experiencing a different physical reality, such as poor circulation or a temperature regulation problem. This guide will help you distinguish myth from medical fact and understand the actual causes behind a persistent feeling of coldness.
