Heat Exhaustion and Heat Stroke in Dubai: How to Recognise and Respond
The difference between heat exhaustion and heat stroke, the warning signs Dubai residents miss, and what to do in the first 30 minutes.
Heat exhaustion — the warning stage
Heavy sweating, weakness, dizziness, nausea, headache, muscle cramps, fast pulse, cool clammy skin, urine that's dark and infrequent. Core temperature is usually below 40°C and the person is still mentally clear. This is your warning shot. Stop, cool, hydrate.
Heat stroke — the emergency
Core temperature above 40°C, confusion, slurred speech, agitation, seizures, loss of consciousness. Skin may be flushed and dry (sweating fails) or still sweaty (exertional). This is a medical emergency — call 998 and start cooling immediately while waiting. Brain damage and death follow if untreated.
The first 30 minutes
Move to air conditioning or shade. Remove excess clothing. Apply cool, wet towels to the neck, armpits and groin. Use a fan. Sip cool water or oral rehydration solution if conscious. If symptoms don't improve within 30 minutes — or worsen at any point — get a doctor. IV fluids shorten recovery in moderate cases from days to hours.
Who's at highest risk in Dubai
Outdoor workers, runners and cyclists training in summer, children left in cars (even for minutes — the temperature kills), elderly residents on diuretics or with dementia, people on blood pressure or psychiatric medications that impair sweating, and recent arrivals who haven't acclimatised.
How we help at home
Same-day home visit with assessment, IV rehydration if appropriate, anti-sickness medication, and a triage decision: stay home with monitoring, or escalate to hospital. We are not a substitute for emergency care in true heat stroke — but for moderate heat exhaustion, home IV often beats a 6-hour ED wait.
Knowing the difference matters
Heat exhaustion: heavy sweating, weakness, dizziness, nausea, headache, muscle cramps, fast pulse. Skin is cool and moist; mental state is preserved. Heat stroke: temperature above 40°C, hot dry skin or profuse sweating, confusion or altered consciousness, possibly seizures. Heat stroke is a medical emergency — call an ambulance immediately while cooling the patient with water and fanning.
Who is most at risk in Dubai
Outdoor workers, runners and cyclists exercising mid-morning to late afternoon, elderly residents whose AC has failed, infants and toddlers in cars (never leave them — even for two minutes), and anyone on diuretics, beta-blockers or anticholinergic medications. New arrivals in their first 1–2 weeks have the lowest heat tolerance.
Recovery and prevention
For heat exhaustion: rest in a cool environment, oral rehydration (water plus electrolytes), and a careful re-introduction to heat exposure over 24–48 hours. An IV drip speeds recovery in moderate cases and is often available at home. For prevention: hydrate continuously rather than in large boluses, schedule outdoor activity for early morning or after sunset in summer, and acclimatise gradually if newly arrived.
Acclimatising new arrivals
Anyone arriving in Dubai during summer needs 10–14 days of gradual exposure before sustained outdoor activity. Start with short morning or evening walks, increase duration progressively, hydrate proactively, and avoid alcohol in the first week. Children and elderly family members visiting from cooler climates need particular attention — most serious heat illness we see in tourists is in the first 48–72 hours after arrival.
Frequently asked
When should I call an ambulance instead of a home doctor?
Call 998 immediately for confusion, loss of consciousness, seizure, body temperature above 40°C, or rapid deterioration. For mild-to-moderate heat exhaustion that's improving with cooling and oral fluids, a home GP visit is usually appropriate.
Can IV fluids treat heat exhaustion?
Yes — for moderate cases that aren't improving with oral fluids, doctor-led IV rehydration restores volume and electrolytes quickly. Severe heat stroke needs hospital-level cooling and monitoring, not home IV.
Can I get an IV drip at home for heat exhaustion?
Yes — our doctor-led home IV therapy service is one of the most common call-outs in summer for residents and tourists with heat-related illness.
