If you want to enjoy Songkran without ending the day exhausted, hydration is the single smartest thing you can plan for. Here's exactly how the RejuveHub medical team approaches it.
Why Songkran dehydrates you — fast
Thailand in April routinely hits 35–40°C. Add hours outside, alcohol, and sweating under the sun, and you lose fluid and electrolytes much faster than you replace them. The tell-tale signs — headache, fatigue, nausea, dizziness — aren't a hangover. They're dehydration wearing a costume.
The rule we give every guest
Drink 250ml of water every 30 minutes you're outside. Alternate alcoholic drinks with a full glass of water. Add coconut water or an electrolyte sachet twice a day. If you're going to party hard, pre-hydrate the night before — not just the morning after.
When to call for an IV
If you've stopped sweating, feel confused or nauseated, or have a headache that paracetamol can't touch, you're past the point of fixing it with a glass of water. An IV drip restores fluid volume and electrolytes in 30–45 minutes. We run a mobile service — the nurse comes to your hotel.
