Cabo’s sunshine is a big part of why people visit, but strong sun, high temperatures, alcohol and long days on the beach or a boat can add up quickly. Heat exhaustion is one of the most common reasons travelers suddenly feel unwell in Los Cabos. Here is how to recognize it, what to do right away, and when to get medical help at your hotel or villa.

Heat exhaustion vs. heat stroke: what is the difference?

Heat exhaustion happens when your body loses too much water and salt through sweating. Common signs include heavy sweating, cool and clammy skin, weakness, dizziness, headache, nausea or vomiting, muscle cramps and a fast, weak pulse.

Heat stroke is a medical emergency. The body can no longer cool itself. Warning signs include a very high body temperature, hot red skin (dry or damp), confusion, slurred speech, fainting or seizures. If you suspect heat stroke, call 911 (Mexico’s emergency number) immediately and start cooling the person while you wait.

What to do right away for heat exhaustion

• Move to shade or an air-conditioned room.
• Loosen or remove extra clothing.
• Apply cool, wet cloths or take a cool shower.
• Sip water or an oral rehydration solution. Avoid alcohol and very sugary drinks.
• Rest and watch the symptoms closely.

Get medical help if symptoms get worse, last more than an hour, or if the person keeps vomiting and cannot keep fluids down.

Who is at higher risk in Cabo?

• Young children and older adults.
• People with heart disease, diabetes or high blood pressure, or who take medicines such as diuretics.
• Anyone drinking alcohol in the sun, especially at pool parties or on boat trips.
• Travelers who are sick with diarrhea or vomiting, since they are already losing fluids.
• People hiking, golfing, fishing or doing sports in the middle of the day.

Simple ways to prevent it

• Drink water regularly through the day, before you feel thirsty.
• Alternate alcoholic drinks with water.
• Plan outdoor activities for the morning or late afternoon.
• Wear a hat, light loose clothing and reapply sunscreen often.
• Take breaks in the shade, especially on beaches and boats.
• Pack or order oral rehydration salts so you have them on hand.

Frequently asked questions

How long does heat exhaustion last?

With rest, cooling and fluids, many people start to feel better within an hour. If symptoms do not improve within about an hour, or they get worse, seek medical care.

Is water enough, or do I need electrolytes?

Water helps, but when you have been sweating heavily or have vomiting or diarrhea, an oral rehydration solution also replaces lost salts.

What number do I call for an emergency in Mexico?

Dial 911. Signs like confusion, fainting, seizures or a very high temperature need emergency care right away.
