You may avoid being outside when it\u2019s brutally hot. But when overwhelming heat comes from your own body, there\u2019s no escaping its intensity. Here\u2019s what you need to know about heat intolerance, its causes, and heat-regulating supplements that may prevent or minimize symptoms of heat intolerance.<\/p>\n

What is heat intolerance?<\/h2>\n

Heat intolerance is when your body and skin are hypersensitive to a rise in temperature. The feeling of overwhelming heat may come on fast and last only a couple of minutes. That can be the case with menopausal hot flashes. But the feeling of being overheated can also develop gradually. When that happens, heat discomfort can last much longer.\u00a0<\/p>\n

Heat intolerance isn\u2019t the same as heat stroke, which can raise your body temperature to as high as 106 degrees Fahrenheit within as little as 10 minutes. It\u2019s also not the same as heat exhaustion, which can occur after several days of exposure to high temperatures. Heat stroke and heat exhaustion are dangerous, heat-related illnesses that are typically caused by being outside in high heat or working in a high-temperature environment.\u00a0<\/p>\n

And while heat intolerance isn\u2019t an illness like heat stroke or heat exhaustion, some medical conditions or illnesses may contribute to the condition.<\/p>\n

Heat intolerance causes<\/h2>\n

If you have heat intolerance, an off-kilter hypothalamus is likely behind your flushed face and sweaty clothes. The hypothalamus gland acts as the \u201ccontrol center\u201d of your brain that regulates body temperature, along with appetite and certain other nervous system functions. The hypothalamus keeps body temperature within a couple of degrees of our normal core temperature of 98.6 F.\u00a0<\/p>\n

\u201cThink of [the hypothalamus] as your nervous system control, like a thermometer in your body,\u201d says Harvey Castro<\/a>, MD, a board-certified emergency medicine physician in Dallas, Texas. When this nervous system monitor isn\u2019t working, it can signal your body to heat up, even when your temperature is normal, he says.<\/p>\n
