Dehydration during travel

Dehydration and Travel: how does dehydration occur when travelling?

Dehydration can occur more easily while you’re travelling for several reasons. Firstly, you may not drink enough fluids simply because you don’t have access to clean and safe drinking water in the area where you are travelling. Or you may be too busy and forget to drink fluids. Dehydration caused by air travel is particularly common and is due to low humidity levels in aircraft cabins. Finally, travellers’ diarrhoea is a leading cause of dehydration in people who travel internationally. In most cases, the diarrhoea occurs in people who travel to areas with poor water and food hygiene.

What are the signs and symptoms I should be aware of?

Watch out for the following symptoms while travelling, as they could mean you are suffering from dehydration:

  • Headache
  • Dizziness or feeling lightheaded
  • Decreased urine output
  • Dry skin
  • Tiredness or sleepiness
  • Thirst

Remember that heat exposure and exercise increases the risk of dehydration. It pays to be aware of this when holidaying, for example when walking and sightseeing.

How can I prevent dehydration when travelling?

Planning ahead is key when it comes to dehydration prevention while travelling. Take extra water with you when travelling outdoors or anywhere where activity levels and heat exposure will increase fluid losses. Avoid drinking alcohol, especially in warm weather. Alcohol increases fluid loss from the body and also impairs your ability to sense the early symptoms of dehydration. Dehydration during air travel can be prevented by sipping from a bottle of water throughout the flight. Avoid caffeinated drinks such as coffee, tea and colas as these can also have a dehydrating effect.

How do I treat the symptoms of dehydration when I’m unable to take time to rest properly?

It may not be possible to take the time to slow down and rest if you become ill or mildly dehydrated while travelling. The most important thing to do is to try to restore hydration by drinking small, frequent amounts of fluids and speak to a healthcare professional for advice about managing the symptoms.

When should I see a doctor for dehydration symptoms?

Symptoms of mild dehydration can usually be managed yourself. However, you should see a doctor immediately if symptoms persist.

Traveller’s Diarrhoea/ Gastroenteritis

Traveller’s Diarrhoea (TD) is caused by infectious agents and most cases begin abruptly. The illness results in increased frequency and volume of stool. Typically, a traveller experiences 4‐5 loose or watery bowel movements a day. Other symptoms may include nausea, vomiting, cramping, bloating, fever, urgency and fatigue. Dehydration may result from the diarrhoea so it’s important to consume oral rehydration drinks to replace lost fluids and electrolytes. If symptoms persist, see a healthcare professional.
