This is achieved by balancing the body's heat production and heat loss. During exercise, the body's heat production rises. To balance this, the body activates its heat loss mechanisms.  \u003c\/p\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eIt generates sweat for evaporative cooling of the skin, and it widens skin blood vessels and raises heart rate to increase blood flow to the skin. When cooling demands are high, the increased blood flow to the skin causes blood to be diverted away from the muscles.  \u003c\/p\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eWhen exercise intensity and\/or environmental heat stress (high ambient temperature, high humidity) are high, the body's heat loss mechanisms can no longer compensate for its heat production. This will lead to an increase in core temperature, skin temperature, and heart rate. This physiological response to heat stress is called \u003cspan\u003eheat strain\u003c\/span\u003e. During athletic endeavours, excessive heat strain causes performance loss. Repeated exposure to heat strain creates heat adaptations. \u003c\/p\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003e \u003c\/p\u003e\u003ch2 style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003e\u003cstrong\u003eMoving Beyond Core Temperature \u003c\/strong\u003e\u003c\/h2\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eCore temperature is an important metric for assessing an athlete’s thermal state. However, core temperature alone does not sufficiently estimate thermal strain on the body. This is because at a given core temperature, performance loss occurs earlier when skin temperature is higher, due to an increase in heart rate and blood flow to the skin. In addition, a high skin temperature increases the feeling of discomfort during exercise in the heat. \u003c\/p\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003e \u003c\/p\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eExtensive research has shown that the concept of \u003cspan\u003emean body temperature \u003c\/span\u003eis one of the top indicators for assessing heat strain. Mean body temperature is the weighted average of the body’s core temperature and skin temperature. This calculation typically requires measurements from different locations of the body.  As the CORE sensor collects data from only one location, extensive laboratory testing by CORE experts has resulted in a formula that allows the CORE sensor to accurately estimate mean body temperature. \u003c\/p\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003e  \u003c\/p\u003e\u003ch2 style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003e\u003cstrong\u003eCORE’s Heat Strain Index \u003c\/strong\u003e\u003c\/h2\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eCORE’s Heat Strain Index converts estimated mean body temperature into a value ranging from 0 to around 10. It gives a real-time, minute-by-minute measure of how hard your body is working to stay cool. \u003c\/p\u003e\u003cul data-rte-list=\"true\"\u003e\n\u003cli\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eA Heat Strain Index between 0 and 0.9 is measured when the thermoregulatory system is not strained. Core temperature may be elevated, but skin temperature is low (ie. when exercising in a cool climate). \u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp style=\"text-align: center; ; white-space:pre-wrap;\" data-rte-preserve-empty=\"true\"\u003eA value of 10 is exceptionally high and represents a core temperature of 40°C\/104°F and a skin temperature of 37°C\/98.6°F. Exercising at these temperatures for too long may have severe consequences for your health and may place you at risk for heat illness or even heat stroke.
