- Avoid direct calques like '*тепловое истощение*'. The standard medical term is 'тепловой удар', though this more accurately translates to 'heat stroke'. For precision, use 'тепловое истощение' or 'перегрев'.
Common Mistakes
- Confusing it with 'heat stroke' (which is more severe and involves cessation of sweating and altered mental state). Incorrectly using it as a verb (e.g., 'I heat exhausted'). Misspelling as 'heat exhaustion'.

FAQ
Frequently Asked Questions
The main cause is the body overheating due to exposure to high temperatures, especially when combined with high humidity and strenuous physical activity, leading to excessive loss of water and salt through sweating.
Immediate treatment involves moving to a cool place, lying down, loosening clothing, cooling the skin with damp cloths or a cool shower, and sipping water or sports drinks. Medical attention should be sought if symptoms worsen or don't improve within an hour.
Heat exhaustion itself is not typically fatal if treated promptly. However, if left untreated, it can progress to heat stroke, which is a life-threatening medical emergency.
Those at highest risk include the elderly, young children, people with chronic illnesses, athletes, outdoor workers, and anyone not acclimatised to hot weather or who is dehydrated.
