When translated, ‘gua’ means to scratch the skin while ‘sha’ stands for the red rash that appears on one’s skin after said scratching happens.Dr Saurabh Shah, dermatologist, Bhatia Hospital, Mumbai explained that a heatstroke occurs when the body overheats to the point that it can no longer regulate its internal temperature through its innate thermoregulatory mechanisms like sweating and transepidermal water loss (TEWL). “The cardinal signs of heatstroke are headache, nausea, dehydration and in extreme cases fever, drop in blood pressure, increased heart rate or cold clammy skin. It must, however, be noted that the aforementioned symptoms extend much beyond the discomfort associated with most sunburns and indicate a definite medical emergency,” he told indianexpress.com.
