Body surface temperature is an important indicator of your health and one of the vital signs. Below is an explanation of the difference between body surface and core temperature, along with practical uses.
The body core temperature, measured by conventional thermometers, is known as equilibrium temperature. It displays the numerical value once it reaches approximately the same temperature as your deep core body temperature.
On the contrary, in the fitness and healthcare market, wearable devices measure body surface temperature using external sensors or proprietary algorithms based on heart rate and other factors, showing it as body temperature.
The body surface temperature, measured by the MOTHER Bracelet, continuously monitors the skin temperature of the area where the device is worn. As a result, it appears 5°C to 6°C lower than the core body temperature. By regularly measuring body surface temperature every day, you can effectively manage your daily health. If you notice fluctuations of more than 0.5°C, it's a signal to pay attention to your body and allocate time for rest and self-care.
Body surface temperature can temporarily increase during exercise due to physical exertion. However, once the body surface temperature returns to your normal range, it indicates a sign of recovery.
Feeling unwell during certain periods could be due to changes in the body's regulatory systems. Factors like decreased peripheral blood flow, lower ambient temperature, or specific phases of your menstrual cycle, such as the follicular phase, could contribute to such variations.
