10 Home Remedies For Heatstroke (Sunstroke)


The rising temperature across the country has increased the number of heatstroke deaths in Kerala. Around 125 cases of heatstroke have been reported in the state.

Heatstroke or sunstroke is caused when the body starts overheating and the temperature rises to 104°F (40°C) or higher, due to the prolonged exposure to high temperatures during the summer months [1] .

The symptoms of heatstroke include high body temperature, alteration in sweating, change in mental state or behaviour, flushed skin, rapid breathing, nausea and vomiting, headache and rapid heartbeat.

Heatstroke requires immediate treatment because it can quickly damage the body's organs like the brain, kidneys, and heart.
