Are you planning to travel soon? With the Christmas break coming up, many people will be taking advantage of this to go on a holiday. But travelling by plane can lead to dehydration. You may also experience traveller’s diarrhoea at your point of destination, which can also lead to dehydration, so it’s best to be prepared.

Why we get dehydrated on planes

High altitudes, low humidity and dry cabins can contribute to dehydration1. Air-conditioned buildings have a relative humidity of between 40-70% yet the relative humidity on airplanes drop to around 20%. The dry environment sees water loss through sweat and evaporation from our skin2. When combined with alcohol, tea or coffee, it can lead to a greater risk of dehydration.

Men lose approximately 2L of water and women lose 1.6L of water on an average 10 hour flight3. This water loss occurs due to respiration, an increased breathing rate on planes and the dry cabin air3. These situations can then lead to headaches and fatigue due to dehydration.

Traveller’s diarrhoea

When people travel from developed to developing countries, they put themselves at risk of traveller’s diarrhoea. Traveller’s diarrhoea is an illness which occurs when people consume contaminated food or water4. Is it likely to occur in nations where sanitation and hygiene standards are poor such as Africa, Asia and the Middle East4.

Symptoms of traveller’s diarrhoea includes abdominal cramps and pain, nausea and having to pass watery stools frequently4. This can then lead to dehydration as you are losing body fluids. 

To reduce the risk of experiencing traveller’s diarrhoea, some of the steps you can take are washing your hands before eating and after going to the toilet, ensuring dishes are dry before eating off of it and eating at clean restaurants4.

How BIOLyte can help

BIOLyte is the ideal solution to take with you when travelling as it can help provide a faster recovery from the conditions above. When travelling by plane, BIOLyte can help provide you with fast rehydration. As an oral rehydration solution, BIOLyte can help restore lost electrolytes.

BIOLyte can also provide a faster recovery from vomiting and diarrhoea. This is due to the addition of prebiotic and zinc (BIOLyte is the only Oral Rehydration Solution in Australia to contain these ingredients!). The prebiotic promotes the growth of beneficial microorganisms in the intestines which helps you to recover faster.

BIOLyte can simply help you get back to your best faster so that you can make the most out of your holiday. If you’re planning to go on holidays soon, ensure you have BIOLyte on you.
