According to the Mayo Clinic, a fever is not an illness in itself, but a symptom of an underlying condition. When your immune system is fighting an infection, it intentionally raises your body's temperature, which explains **why does my head feel hot when I have a fever?**

While a warm forehead is a classic and common sign that people check for a possible fever, it is an unreliable indicator. The most accurate and medically sound way to determine if you have a fever is to use a thermometer.

According to reports, as many as 50% of trauma patients arrive at the hospital already hypothermic. The primary purpose of a hypothermia blanket is to manage a patient's body temperature, preventing or treating both dangerously low (hypothermia) and high (hyperthermia) body temperatures.

Feeling cold when everyone else is comfortable can be more than just a minor annoyance; it can be a sign your body's temperature regulation is off. This persistent chill prompts many to ask, **why does my body stay cold for so long?** Exploring the complex medical and lifestyle factors can help shed light on this common issue.

The hypothalamus, a tiny region of the brain, acts as the body's thermostat, regulating temperature around 98.6°F (37°C). However, during an infection, this set point is deliberately raised through a complex physiological cascade. The core question, "What is the physiological trigger for a fever?" leads directly to understanding this intricate immune and neurological response.

Your body's core temperature is tightly regulated around 98.6°F (37°C), so ingesting a substance with a different temperature can trigger a fascinating response. This is a key reason **why do I get so cold after drinking water** is a common question, as your system works to maintain homeostasis.

Feeling consistently cold when others are comfortable, a condition known as cold intolerance, is a common experience. If you've been asking, **why does my body not stay warm?**, the answer can range from simple lifestyle factors to more complex underlying medical conditions that affect how your body regulates heat.

According to the Centers for Disease Control and Prevention (CDC), heat-related illnesses can occur when the body's natural cooling mechanisms are overwhelmed. Recognizing what are the signs of internal heat is crucial for preventing more severe conditions like heat exhaustion and heat stroke.

While a temperature reading above the normal range is often mistaken for a fever, medical experts distinguish a crucial difference: true fever involves a regulated increase in the body's hypothalamic 'thermostat' set-point. Understanding what causes elevated temperature but not fever is essential, as the underlying reasons and treatments vary significantly. This guide will explore the non-infectious factors that can cause your body temperature to rise.

The human body is remarkably precise at thermoregulation, maintaining a core temperature around 98.6°F (37°C). However, the temperature drops considerably in the parts furthest from the heart, which answers the question: which part of the body is always cold?. The most common culprits are the hands and feet.
