Songkran Health Tips: How to Stay Safe During Thailand’s Water Festival

Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Doctor Bangkok. Last reviewed: July 2026

If you are planning to join Songkran in Bangkok, or you are already out there and starting to feel off, this is what I want you to know. April in Bangkok is brutal even without a water festival. Add hours in the sun, soaking wet clothes, and street drinks, and your body is working a lot harder than usual.

I see a spike every Songkran, and the pattern is always the same. People wait too long. A headache becomes heat exhaustion. A mild stomach upset becomes real dehydration. A red eye becomes an infection that needs treatment. Almost everything I see during this period was avoidable, or at least manageable, if the person had acted earlier.

Heat, Sun, and Your Body — What April in Bangkok Actually Does

Bangkok in April is the hottest month of the year. Temperatures regularly hit 38 to 40 degrees Celsius, and with humidity, it feels much worse. Standing on Silom Road or the Sukhumvit strip for hours, soaking wet and drinking, puts your body under real stress.

Heat exhaustion is what I see most often. You feel weak, dizzy, and a bit nauseous. Your skin is pale and cool despite the heat, and your heart rate picks up. Move to shade, drink water with electrolytes, and rest. Most people recover within an hour.

Heatstroke is different, and it is serious. Your temperature goes above 39 degrees, your skin turns hot and dry, and you may feel confused or stop sweating. If someone with you is confused, cannot stand properly, or has stopped sweating in this heat, get them inside and call for help immediately. This is a medical emergency.

The fix is simple. Drink before you feel thirsty. Take shade breaks every hour. Wear a hat, sunscreen, and light clothing even if you expect to get wet.

Dehydration — The One Everyone Underestimates

Most people at Songkran are not drinking enough water. They are drinking alcohol, which makes dehydration worse. They are also sweating heavily without realising how much fluid they are losing.

Mild dehydration feels like a headache and dry mouth. Moderate dehydration means very dark urine, feeling lightheaded when you stand, and a sharp drop in energy. Severe dehydration can send you to a clinic.

What I tell patients is simple: if you are drinking alcohol in this heat, match every drink with a glass of water. An oral rehydration solution from any 7-Eleven works much better than plain water once you are already behind.

If you cannot keep fluids down, IV rehydration is the fastest fix. Doctor Bangkok offers IV drip therapy for dehydration and recovery that restores fluids and electrolytes directly. It takes about an hour and most patients feel significantly better by the end.

Waterborne Infections — Eyes, Gut, and Skin

The water at Songkran comes from hoses, storage tanks, water trucks, and buckets. It is not clean water. It can carry bacteria, viruses, and fungi, and this matters for three parts of your body.

Your gut is at risk if you swallow any of it, which is hard to avoid. Stomach cramps, nausea, and diarrhoea are common in the days after Songkran. Most cases settle in two to three days with rest and oral rehydration. Come in if you have bloody diarrhoea, a fever above 38.5 degrees, or you cannot keep fluids down.

Your eyes are at serious risk, especially if you wear contact lenses. Festival water can carry bacteria that cause painful eye infections. Lenses trap these organisms right against your eye. Wear glasses or goggles during water fights instead. If your eye becomes red, painful, or starts producing discharge after water exposure, get it assessed. Do not wait on an eye infection.

Your skin can also pick up infections through cuts or broken skin. If a wound becomes red, swollen, warm, or starts producing pus in the days after Songkran, come in for proper wound care rather than hoping it clears up on its own.

Dengue Fever — The Risk Most People Do Not Think About

April is one of the higher-risk months for dengue fever in Bangkok. Mosquitoes breed in standing water, and after Songkran, there is no shortage of that. People are also outside for hours in shorts and wet clothing, which gives mosquitoes easy access.

Dengue starts with a sudden high fever, intense headache, pain behind the eyes, and muscle aches bad enough to make moving uncomfortable. A rash often appears after a few days. There is no antiviral treatment for dengue, so what matters is catching it early and keeping you properly monitored.

If you develop a high fever within two weeks of Songkran and it does not feel like a regular cold, come in for a dengue test. At Doctor Bangkok, we run a rapid test and have a result for you quickly.

Use insect repellent with DEET, cover your arms and legs in the evenings, and check that your accommodation does not have standing water nearby.

Alcohol Safety and Methanol Risk

Street drinks at Thai festivals are usually fine, but counterfeit alcohol is a real risk at large public events. Methanol, a toxic substance sometimes used to cut cheap spirits, can cause vision problems, confusion, and organ failure. It is rare, but it happens.

The warning signs appear hours after drinking: headache, nausea, and sudden blurred vision. If someone develops vision changes or confusion after alcohol, that is an emergency. Get to a doctor immediately.

Stick to sealed bottles from reputable shops. Be cautious with very cheap spirits and pre-mixed buckets from street vendors where you cannot see the source.

Road Safety During Songkran

Thailand’s road toll during Songkran is one of the highest of any festival in the world. Drunk driving is a serious problem, and wet roads add to the risk. Walk where you can. If you need a vehicle, take a licensed taxi or rideshare app rather than a motorbike. Wear shoes with grip on wet surfaces. Falls on slippery pavements are a common reason people end up needing wound care during this period.

When to See a Doctor — Symptoms You Should Not Wait Out

Most Songkran health problems are mild and short-lived. But some are not, and waiting is the biggest mistake I see.

Come in promptly if you have a fever above 38.5 degrees that does not come down, vomiting that stops you keeping fluids down, bloody diarrhoea, a red or painful eye with discharge, a wound that looks infected, or any confusion or difficulty standing. These are not symptoms to manage alone in a hotel room in Bangkok’s heat.

If you are unsure, contact us. It is always faster to rule something out than to deal with a problem that has been left too long.

Getting Medical Help Without Leaving Your Hotel

Here is something most people do not realise during Songkran: getting to a clinic is genuinely hard. Streets are flooded with water fights, transport is disrupted, and if you are unwell, going outside is the last thing you want to do.

Doctor Bangkok’s hotel doctor service means you do not have to. A physician can come to your hotel room, assess you, and in many cases treat you on the spot. The service covers central Bangkok including Sukhumvit, Silom, and Sathorn, and runs around the clock, including all Songkran public holidays.

You can reach us by WhatsApp or phone to arrange a visit, and we can usually be with you within the hour. If getting to a clinic feels impossible right now, that is exactly what this service is for. You can find out more about our travel health and hotel doctor service on our website.

What to Pack for Songkran

You do not need a lot, but a few things will save you real trouble. Carry oral rehydration sachets from any pharmacy. Bring waterproof sunscreen and reapply it often. Pack insect repellent with DEET. Have antiseptic wipes and plasters on hand. Wear shoes with grip, not flip flops on wet streets. Keep your travel insurance details accessible. And know where your nearest English-speaking clinic is before you need it.
