Heat Exhaustion: Not Sweating? It Can Be Sign Of Heat Exhaustion | Bhubaneswar News
Bhubaneswar: If your body is not sweating despite being exposed to the heat, it could be a warning sign of imminent heat exhaustion that can culminate into a heatstroke, experts have said.
“A heatstroke happens when the environmental temperature is exceedingly more than the normal body temperature of 37°C. The body stops transpiration – the process in which it is cooled – when people have a heatstroke,” the experts added.
“One can be alerted when he has heat exhaustion with symptoms like fatigue, general weakness and headache that can result in a heatstroke.We sweat to keep the body cool, but in case of heat exhaustion with constant exposure to sun, the body starts to burn itself as body temperature increases beyond tolerable limit, thereby causing tis stop perspiration,” Dr Jayant Panda, professor of medicine at SCB Medical College and Hospital, Cuttack, said. “Not being able to cool the body can result in excess heat generation in the body and then the person can collapse due to multi-organ failure,” he added.
Dr E Venkat Rao, who works at a city-based hospital, said “Heat stroke happens owing to the inability of the body to adapt to the external temperature. When muscle is damaged due to heat exhaustion, a protein called myoglobin is released, which damages the kidney and then multi-organ failure leads to coma and subsequently, death.”
“Hypothalamus in our brain regulates the body temperature. When it fails to do so, muscle break down begins,” said Dr Sampat Das, senior pulmonologist.
Those working outside for long hours especially are caught unawares when the body shows signs of heat exhaustion. Health experts said that such workers in daytime should keep themselves hydrated and put water on their clothes to maintain body temperature. “Those working long hours are advised intermittent aeration by putting water on their clothes and by consuming food that keeps the body cool and drinking water at regular intervals. It is better if they take rest every hour and cool the body by splashing water on it or rubbing it with wet clothes,” Dr K S Kumar, a medicine specialist, said.
