Collapse in 41 Degree Heat at the 800 m Finish
It is 1:20 p.m. on 18 May at a school sports day in the plains of Uttar Pradesh. The shade temperature is 41 degrees Celsius and the humidity is low; the 800 m race for boys of Classes 9 and 10 has just finished on a ground with no shade and no water point inside the arena. Ten minutes after finishing, a 15-year-old boy is seen staggering near the finish line. His skin is hot and dry, he is confused about which house he belongs to, his pulse is about 130 per minute and his breathing is fast. One teacher runs for a bottle of chilled packaged water; another suggests rubbing ice on his chest; a third says he is only exhausted and should be made to walk. The first-aid box contains oral rehydration sachets, cotton, roll bandage, antiseptic lotion, scissors and plaster, but no thermometer, no ice packs and no stretcher. The nearest community health centre is 12 km away and the ambulance number is 108. Two other runners are sitting in the sun holding their calves, and a girl from Class 9 says she feels nauseated.
1. What is the most likely condition, how is it distinguished from the milder heat illness, and what must be done in the first ten minutes with the material available?
Read the worked answer
This is heat stroke until proved otherwise, not simple exhaustion. The discriminators are hot dry skin, confusion and disorientation, a pulse near 130 and collapse after exertion at 41 degrees. Heat exhaustion gives heavy sweating, cool clammy skin, temperature roughly 38 to 40 degrees, dizziness, headache and nausea, but the athlete stays oriented and can answer questions. Altered mental status after heat exposure is the red flag; heat stroke carries a core temperature above 40 degrees and can kill, and no thermometer is needed to act when consciousness is affected.
First ten minutes, in order:
- Move him to shade and lay him down; loosen and remove the jersey and shoes.
- Call 108 immediately and say heat stroke, unconsciousness risk and the road distance - the call must not wait for improvement.
- Fan him and apply water-soaked cloth to the head, neck, armpits and groin; keep the skin wet and the air moving. Remove and re-wet cloths as they warm.
- Check that he is breathing, place him in the recovery position if he vomits, and stay with him.
- Do not give him water or ORS while he is confused - the risk of aspiration is real.
- Record pulse and breathing every five minutes and hand the note to the ambulance staff.
Cooling starts on the ground, not at the health centre 12 km away.
2. Evaluate the three suggestions made by the teachers and explain how ORS should actually be used for the two runners with cramps and the nauseated girl.

The suggestions:
- Chilled packaged water is useful for cooling and for an alert athlete's thirst, but it is not the priority, and a large cold drink given to a confused boy may cause vomiting and aspiration. Small sips only if he is fully alert.
- Ice on the chest wastes time - cooling is most effective over the large vessels at the neck, armpits and groin, together with fanning, wetting the whole skin and shade.
- Making him walk is the most dangerous advice. Exercise generates more heat, and a confused athlete will fall. He should be lying down, being cooled, and observed.
ORS: one sachet dissolved in one litre of clean water, not in a partially filled bottle.
- Cramping runners: stop activity, sit in shade, stretch the calf gently, and give about 200 to 250 ml to sip over 15 to 20 minutes, repeating as tolerated. Cramps in heat usually reflect salt and fluid loss, so plain water alone is not enough.
- Nauseated girl: shade, rest, loosen clothing, and small frequent sips; if she vomits, stop, let her rest and watch her - persistent vomiting or drowsiness means referral.
- No salt tablets, no alcohol rub, no forcing fluids into a drowsy person.
3. What changes should be made to the rest of the day, and what should the school fix before next year's sports day?
Read the worked answer
Rest of the day:
- Suspend all track events until after 5 p.m.; if that is not possible, cancel the remaining distance races. Sprint and field events may resume only with a shaded rest area and water inside the arena.
- Set up a shaded first-aid post with water, ORS, ice or cold water, wet cloths and a stretcher, staffed by a teacher who stays there.
- Announce a water break every 15 to 20 minutes and give every athlete 150 to 250 ml; shorten each event's exposure and rotate heats quickly.
- Inform the injured boy's parents and record the incident in writing the same day.
Before next year:
- Schedule the meet in the early morning or after 5 p.m.; never run 800 m and 1500 m between noon and 4 p.m. in May.
- Acclimatise athletes over 7 to 14 days before the meet rather than on the day.
- Keep a thermometer, ice box, stretcher and a printed emergency plan with 108 displayed, and train at least two teachers in first aid and heat illness.
- Weigh volunteers before and after a hard event; a loss above 2 per cent of body mass means inadequate fluid intake.
- Record every collapse and review the plan with the principal afterwards; a near miss is a warning, not a story.
