The sun in Patong is stronger than most visitors expect. You walk the beach, ride a boat, or sit on Bangla Road, and your body slowly overheats. At first you just feel tired and thirsty. But heat illness can turn serious fast, and many people miss the early signs until they feel really unwell.
This guide from our doctors makes it simple. It shows you the difference between heat exhaustion and heat stroke, what to do for each, and when to get help fast. Learn these signs and you can act with a clear head, day or night, here in Patong Phuket.
What Heat Illness Is and Why Patong Gets So Hot
Your body works hard to stay at one steady temperature. In the heat, it cools you by sweating. But when it is very hot and humid, sweat cannot dry off your skin, so cooling stops working well. Your core heats up. This is heat illness. It starts mild, as heat cramps or heat exhaustion, and can climb to heat stroke, which is a true emergency. Patong is hot and sticky most of the year, which makes it harder for your body to cool down.
Tourists are hit more than locals for good reasons. You may not be used to tropical heat. You walk more, drink more alcohol, and sit on open boat decks and beaches with no shade. Add a long flight the day before, and your body is already tired and short on fluids. All of this stacks up. Knowing the signs early is the best way to stay safe on your holiday.
Heat Exhaustion: Signs and What to Do
Heat exhaustion is the warning stage. Your body is struggling but still fighting to cool down. The key sign is heavy sweating. Your skin feels cool, damp, and pale. You feel weak, dizzy, and sick, and you may get a headache or muscle cramps. Your heart beats fast and you feel very tired. This is your body waving a red flag. It is not yet an emergency, but it needs action right away before it gets worse.
Act fast and most people recover. Get out of the sun and into shade or air-con. Lie down and raise your legs a little. Sip cool water or a rehydration drink slowly. Loosen tight clothes and cool your skin with a damp cloth or fan. Rest for a good while, not just a few minutes. If you do not feel better within 30 minutes, or you cannot keep fluids down, see a doctor.
Heat Stroke: The Emergency Signs
Heat stroke is a medical emergency. It happens when your body can no longer cool itself and your core temperature climbs dangerously high. The signs are different from heat exhaustion, and the biggest one is a change in the brain. The person may act confused, slurred, or strange, or they may faint or have a fit. The skin is often hot and red, and may feel dry because sweating has stopped. This can harm the brain and organs.
If you see these signs, act like it is an emergency, because it is. Call for help and get the person to a doctor fast. While you wait, move them into shade, take off extra clothes, and cool them any way you can with wet cloths, a fan, or cool water on the skin. Do not wait to see if it passes. Heat stroke gets worse by the minute, so fast cooling and medical care save lives.
Who Is Most at Risk and How to Prevent It
Some people overheat faster than others. Young children and older adults are more at risk, since their bodies handle heat poorly. So are people who drink a lot of alcohol, take certain medicines, or have heart or health problems. But healthy young tourists get heat illness too, often on boat trips or long days out with no shade and not enough water. The heat does not care how fit you are if you push too hard.
Prevention is simple and works. Drink water often, before you feel thirsty, and go easy on alcohol in the day. Wear a hat and light clothes, and find shade in the hottest hours, from late morning to mid-afternoon. Take breaks in air-con, use cool showers, and never leave anyone in a parked car. Watch out for each other. If a friend goes quiet, confused, or stops sweating in the heat, act at once.

Frequently Asked Questions
What is the main difference between heat exhaustion and heat stroke?
The biggest difference is the mind and the skin. With heat exhaustion, you sweat heavily and feel weak and dizzy, but your thinking is still clear. With heat stroke, the brain is affected, so the person acts confused or faints, and the skin often turns hot and dry as sweating stops. Heat stroke is an emergency and needs a doctor fast.
How much water should I drink in Patong to avoid heat illness?
There is no single number, but the key is to drink often and before you feel thirsty. On hot days out, sip water every little while, not just at meals. If your pee is dark, you need more. Go easy on alcohol during the day, as it dries you out. On boat trips, bring more water than you think you need.
Can I treat heat exhaustion myself at the hotel?
Often, yes. Get into shade or air-con, lie down, and sip cool water or a rehydration drink slowly. Cool your skin with a damp cloth and rest for a good while. Most people feel better within 30 minutes. But if you do not improve, cannot keep fluids down, or start to feel confused, see a doctor without delay.
Is heat stroke really a medical emergency?
Yes. Heat stroke can harm the brain and organs within a short time. If someone in the heat becomes confused, faints, has a fit, or has hot skin that has stopped sweating, treat it as an emergency. Cool them fast with wet cloths and a fan, and get them to a doctor right away. Do not wait to see if it passes.
