Thermoregulation is a natural process carried out by the human body, which activates central and peripheral mechanisms in order to maintain homeostasis and the body’s vital functions. Read on to find out how core body temp relates to health and how it affects athletic performance.

The body activates its thermoregulatory mechanism under the control of the hypothalamus, based on information constantly received from thermal sensors in the skin, spinal cord, and different internal organs.

It’s a vitally important process, as it helps to maintain the internal body temperature at an average of 37°C. We are well aware that any change to this value can affect cellular properties and lead to physiological dysfunctions.

What does core body temp say about general health?

A person’s core body temperature tells more than you think about their state of health. In medical terms, measuring it is very important, as it can warn us of the presence of certain diseases that are characterized by an increase or decrease in body temperature.

For instance, when we have a fever, this creates generates an increase in temperature due to a pathological cause.

For this reason, the human ability to thermoregulate is indispensable for our survival and enables us to enjoy good health. An inadequate internal temperature can lead to either hypothermia or hyperthermia.

These are conditions that can cause heat stroke, dehydration, decreased performance, or even brain damage.

On one hand, hypothermia occurs when the core body temperature drops below 36°C. Its main symptoms are pale, cold skin, mental confusion, drowsiness, and a slower heart rate than normal.

Hyperthermia, on the other hand, is when the body’s core temperature rises above 42°C. This can result in a loss of consciousness, headaches, an increased heart rate, and a drop in blood pressure.

How is core body temp linked to sports performance?


According to a study carried out by the Athlete Health and Performance Research Centre, acclimatizing the body to heat during exercise can reduce the risk of severe heat illness, alleviate physiological stress and improve aerobic performance in hot and potentially temperate environments.

This can only be achieved through bodily adaptations that include increased sweating and skin blood flow, a low body temperature, reduced cardiovascular stress, altered metabolism, and enhanced cellular protection.

So, when it comes to athletes, keeping track of their temperature can have great benefits for their performance.

Research published by the Gatorade Sports Science Institute concluded that monitoring core body temperature during sports activity has multiple benefits.

These include preventing exercise-related heat stroke, controlling the intensity and ensuring safety during workouts, and allowing heat tolerance testing during competitions. These benefits help to increase performance in physically active people, as well improving their safety.

Measure your core body temperature with smart sensors

If you would like to monitor your temperature during your different sports activities and obtain accurate data in real-time, then you can purchase non-invasive wearable devices that use Core sensors.

This modern thermal energy transfer technology uses the power of artificial intelligence algorithms to detect heat moving to and from the body in order to calculate core body temperature in real time.

Core temperature sensors provide life-saving data that can help athletes during high-intensity workouts and keep track of their body temperature in order to improve their performance. In addition to this, it’s recommended to combine them with a heart rate monitor to provide greater accuracy.

Core body temp opinions include those of Olympic medallist Kristian Blummenft and Swiss professional mountain biker Alessandra Keller, both of whom have reported using the sensors to implement training strategies and make significant improvements to their productivity in hot weather.

Temperature and health are more closely linked than you might think

Core body temperature reveals a lot about a person’s overall health, and keeping track of it during high-impact physical activities can provide valuable data that can help enhance an athlete’s future performance.

So, if you would like to maintain your well-being and improve your performance, then getting a quality temperature monitoring device is a great idea that will help you to develop adaptive training patterns and slowly work your way up the ladder.
