Travel experts at Wild Packs are warning holiday-goers to avoid consuming alcohol while flying as this can lead to dehydration, impaired judgment, and potential health issues.
A recent study by the Institute of Aerospace Medicine found that the body absorbs alcohol more quickly, speeding up the intoxicating effect. However, the combined altitude and alcohol can strain the heart and lungs, and cause symptoms like chest pain, shortness of breath, or severe dizziness.
As 1 in 10 Brits confess to getting drunk on a flight, Travel expert Jamie Fraser for US summer camp Wild Packs has explained the hazards of drinking on flights and top tips for staying safe and hydrated in the air.
“Having a drink on a flight might seem like a good way to unwind, but it carries certain risks including health issues. Being aware of these effects and taking sensible precautions can help passengers have a safer and more comfortable journey.”
- You’re more likely to become dehydrated: “The air inside the plane has very low humidity, around 10%, which can quickly lead to dehydration, causing dizziness, headaches, and fatigue. On top of that, people often drink less water during flights. If you add alcohol into the mix, the risk of dehydration increases even further, as alcohol acts as a diuretic, making the body lose even more fluids.”
- Increase the risk of blood clots: “Dehydration from alcohol, combined with long periods of sitting, raises the risk of blood clots and deep vein thrombosis. This risk increases even more if the alcohol interacts with any food or medication you consume as well as during your sleep.”
- Drinking can put a strain on your heart: “Alcohol can weaken heart muscles and raise blood pressure, increasing the risk of heart disease. When combined with the effects of cabin pressure and long-haul travel, drinking before falling asleep on a flight can put additional strain on the heart. Studies have shown that this can reduce blood oxygen levels and increase heart rate. This not only disrupts deep sleep but makes those with pre-existing heart conditions more vulnerable to heart disease.”
How to minimise the risks from drinking when flying
- Drink responsibly: “Moderation is important when consuming alcohol on a flight. Avoid excessive drinking and be mindful that alcohol can have a stronger effect at high altitudes.”
- Stay hydrated: “The cabin has low humidity, and alcohol only makes this worse. To counteract its effects, drink plenty of water before and during your flight. Best practice is to have at least one glass of water per alcoholic drink.”
- Eat before your drink: “Drinking on an empty stomach can lead to quicker alcohol absorption, intensifying its effects. Having a proper meal beforehand can help slow this process and keep you feeling steady.”
- Know your limits: “Factors like fatigue and dehydration can make alcohol’s effects even stronger. Pay attention to how you’re feeling and pace yourself accordingly.”
- Respect the cabin crew: “Flight attendants are there to ensure everyone’s safety and comfort. If they suggest you’ve had enough, it’s best to take their advice.”
- Save drinking for after the flight: “There’s plenty of time to enjoy a drink when you land at your destination. Having a drink on holiday is often part of the travel experience, so consider waiting until you arrive.”
- Skip drinks if you are planning on sleeping: “If you’re on a long-haul flight and hoping to rest, remember that alcohol can disrupt sleep quality. It may be worth skipping the drinks if rest is a priority.”
