Key takeaways
- There is no instant hangover cure in Thailand, but rehydrating early and resting in the shade makes a real difference.
- Heat and sweat add to the fluid you lose from alcohol, so tropical hangovers often feel worse than at home.
- Oral rehydration salts, a light meal and a slow morning are the backbone of any recovery plan.
- A nurse-led IV drip at your accommodation is one option if you are struggling to keep fluids down.
A sunset cocktail turns into a beach bar, the beach bar turns into a late one, and suddenly it is 9am, the room is already warm and your head is pounding. If you are looking for a hangover cure in Thailand, the honest answer is that nothing works like a magic switch. What you can do is help your body recover faster, and on Koh Lanta that mostly comes down to fluids, shade, food and rest.

This guide walks you through why hangovers feel so rough in the tropics, a practical morning-after plan, and when it is worth getting help.
Why do hangovers feel worse in tropical heat?
Alcohol is a diuretic, which means it makes you pass more urine than you otherwise would. At home, you might wake up a little dry. In Thailand, you have usually spent the previous day sweating in the sun as well, so you start the night already short on fluids and salts.

Add a warm bedroom, a fan instead of air conditioning, or a long, humid night on the dance floor, and the gap gets bigger. Dehydration is not the only cause of a hangover, as poor sleep, irritation of the stomach lining and the by-products of breaking down alcohol all play a part, but it is the piece you can do the most about.
Sweet mixers, buckets and long drinks also go down easily in the heat. It is very easy to drink more than you realise when everything tastes like fruit juice.
Your hangover cure Thailand plan: the first hour
Whatever you do, do not start the day by heading straight into the sun. Give yourself an hour to get the basics in.

- Drink slowly and steadily. Sip a glass of water every 10 to 15 minutes rather than gulping a whole bottle, which can upset a delicate stomach.
- Add electrolytes. Oral rehydration salts (ORS) sachets are sold in pharmacies and convenience stores. They replace the sodium and potassium lost through sweat and urine far better than plain water.
- Cool down. A cool shower, the air conditioning on, or a shaded spot with a breeze helps your body stop losing more fluid.
- Eat something plain. Toast, plain rice, a banana or a bowl of rice soup is gentle on the stomach and helps steady your blood sugar.
If you take a painkiller, paracetamol is generally a better choice than ibuprofen or aspirin on an empty, irritated stomach, but stick to the dose on the packet. Paracetamol and heavy drinking do not mix well, so do not exceed the recommended amount, and check with a pharmacist if you have any liver problems or take other medication.
Koh Lanta tip: Pharmacies are easy to find in Saladan and along the main west-coast road, and staff are used to tourists asking for rehydration salts and something for a headache. Show them the packet or a photo if you are not sure of the name.
What to eat and drink the morning after
Your stomach may not be keen on a full Thai breakfast, but some local options are surprisingly kind. A bowl of khao tom (rice soup) or jok (rice porridge) is soft, salty and warming. Fresh coconut water is light and easy to sip, although it is not a complete replacement for ORS.

- Good choices: water, ORS, coconut water, rice soup, plain noodles, eggs, toast, fruit such as banana or watermelon.
- Go easy on: very spicy curries, greasy fried food, strong coffee on an empty stomach, and very sugary energy drinks.
- Skip completely: the “hair of the dog”. Another drink only delays the hangover and adds to the dehydration.
Coffee is fine for many people once you have some water and food in you. Just do not let it replace your fluids.
How to get over a hangover fast without wrecking your day
Speed matters on holiday, because nobody wants to lose a full day of a trip. The trick is to rest smartly rather than force yourself onto a boat or scooter feeling shaky.

- Plan a slow morning by the pool or in the room, then reassess around lunchtime.
- Stay out of the strongest sun, roughly late morning to mid-afternoon.
- Postpone snorkelling, diving and island-hopping boat trips. Seasickness on top of a hangover is miserable, and diving with alcohol still in your system is unsafe.
- Do not ride a scooter until you feel fully alert. Alcohol can stay in your system well into the next morning.
- A nap in a cool room is one of the most underrated hangover remedies there is.
When an IV drip can help
Some mornings, sipping water just is not working. If you feel nauseous, cannot keep much down, or have a long travel day ahead, a Hangover Recovery drip is one way to rehydrate more directly.
With our service, a registered nurse comes to your villa, hotel or bungalow, does a short health check first, and then gives the drip over roughly 45 to 60 minutes. The Hangover Recovery drip contains 1 litre of saline with B complex vitamins and vitamin C, plus anti-nausea medicine and pain relief if they are suitable for you. Many guests feel better afterwards, but it supports your recovery rather than undoing the night before. You can read the full process on our how it works page.

How to enjoy Koh Lanta nightlife and feel better tomorrow
Koh Lanta nightlife is relaxed compared with some islands, but Long Beach (Phra Ae) has plenty of bars and the west coast is lined with sunset spots. A few simple habits can save your next morning.

- Start the evening well hydrated, especially after a day in the sun.
- Alternate each alcoholic drink with a glass of water.
- Eat a proper meal before you go out, not just bar snacks.
- Be cautious with buckets and free-poured spirits, as it is hard to know how strong they are.
- Have an ORS sachet and a full bottle of water ready by the bed before you leave.
- Arrange your ride home in advance rather than riding a scooter after drinking.
When to get medical help
A hangover should ease over the day. Call 1669 (Thailand’s emergency ambulance number) or go to hospital straight away if someone is confused, very drowsy or hard to wake, has a seizure, is breathing slowly or irregularly, has bluish or very pale skin, or is vomiting repeatedly while barely conscious. These can be signs of alcohol poisoning. Also seek medical help for vomiting blood, severe abdominal pain, chest pain, or if you suspect a drink was spiked. Koh Lanta Hospital is near Lanta Old Town, and larger hospitals are in Krabi Town.
The bottom line on a hangover cure in Thailand

Rehydrate with water and electrolytes, eat something plain, stay cool and give yourself a slow start.

Pharmacies in Saladan and along the main west-coast road sell ORS sachets, and many convenience stores stock them too.
