Cabo’s average summer high is 92°F, with heat indices that routinely push past 100°F when humidity rises. Add a couple of hours on a sun lounger, a sweaty hike, or a tequila tasting in the afternoon and heat illness is one of the most common reasons travelers call for an emergency IV. Knowing the difference between heat exhaustion (where an IV usually solves it) and heat stroke (where you need a hospital) matters more than any other distinction we’ll cover here.
Heat exhaustion vs heat stroke — the line
Heat exhaustion: heavy sweating, weakness, headache, dizziness, nausea, cool clammy skin, fast pulse, body temperature usually below 104°F (40°C). Mental status is normal — you may feel awful but you’re clear-headed.
Heat stroke: body temperature ≥104°F with neurological changes — confusion, slurred speech, agitation, seizure, loss of consciousness. Skin may be hot and dry (classic) or still sweating (exertional). This is a medical emergency. The body has lost the ability to regulate temperature and organ damage can begin within minutes.
What to do immediately for suspected heat stroke
- Call our emergency line +52 1 624 409 5065 — or 911 if you’re alone and the patient is altered.
- Move the patient to shade or air conditioning.
- Cool aggressively — wet towels, ice packs to neck/armpits/groin, fanning, immersion if available.
- Do NOT make them drink large amounts of cold water if they’re confused or vomiting — aspiration risk.
- Wait for medical transport. Heat stroke is hospital-level care.
Our ambulance service and emergency care coordination handle the hospital escalation; we don’t try to treat heat stroke at your hotel because it isn’t the right setting.
When an IV is the right answer (heat exhaustion)
For heat exhaustion without neurological changes, a medical IV at your hotel or in our clinic resolves the problem quickly:
- 1–2 liters of cool lactated Ringer’s or normal saline at a moderate rate.
- Magnesium, potassium, and B-complex to replace what you’ve lost in sweat.
- Zofran if nausea is significant.
- Toradol when appropriate for headache.
- Active cooling — cool environment, wet cloths, ice packs in the same vascular spots.
- Vitals reassessed at 15 and 30 minutes; physician can escalate if you’re not responding.
Most patients feel significantly better within 30 minutes and back to normal by the next morning, provided they avoid further heat exposure that day.
Prevention is doable
The interventions are simple but rarely followed:
- Drink water steadily, not just when thirsty — a liter for every two hours outside is a reasonable starting point.
- Add electrolytes (ORS sachet, low-sugar sport drink) once a day in heat, more if you’re sweating heavily.
- Schedule heavy activity (hikes, jet ski, tours) before 10am or after 4pm in summer.
- Use shade and breeze; air conditioning periodically resets your core temperature.
- Skip alcohol during peak heat hours — it accelerates fluid loss and impairs your judgment about how hot you actually are.
Special-risk travelers
- Children and elderly tourists — both lose temperature regulation faster than healthy adults.
- Cardiac patients on diuretics or beta-blockers.
- People on stimulants, including ADHD medications and some weight-loss drugs.
- Anyone with a recent illness or who has been drinking heavily.
If you or a traveler with you fits any of these, the threshold for calling us early is low.

Frequently asked questions
What’s the difference between heat exhaustion and heat stroke?
Heat exhaustion: feel terrible but mentally clear, body temp usually below 104°F. Heat stroke: body temp ≥104°F plus neurological changes (confusion, agitation, seizure). Heat stroke is an emergency.
Can a mobile IV at my hotel handle heat stroke?
No. Heat stroke needs hospital monitoring and aggressive cooling.
How fast should I feel better with the IV for heat exhaustion?
Most patients improve significantly within 30 minutes of starting the drip.
Should children get an IV for heat illness?
Sometimes yes; the doctor will assess. Pediatric IV is offered at the clinic when appropriate.
