Enjoying a tipple at 30,000 feet might seem like the perfect way to kick off your holiday, but travel gurus are now advising against it.
A recent study by the Institute of Aerospace Medicine has shown that alcohol is absorbed more rapidly in the body when flying, amplifying its effects and potentially leading to heart and lung strain, with symptoms such as chest pain, breathlessness, or intense dizziness.
With a staggering one in ten Brits admitting to overindulging on a plane, travel expert Jamie Fraser from US summer camp Wild Packs has highlighted the dangers of drinking while flying.
He cautioned: “Having a drink on a flight might seem like a good way to unwind, but it carries certain risks including health issues.”
Jamie emphasised the importance of being mindful of these risks to ensure a safer and more pleasant flight experience.
He also pointed out the increased likelihood of dehydration when consuming alcohol mid-flight, explaining: “The air inside the plane has very low humidity, around 10%, which can quickly lead to dehydration, causing dizziness, headaches, and fatigue.”
Given that passengers often drink less water than usual on flights, mixing in alcohol only heightens the dehydration risk. The dehydration that can ensue coupled with extended periods of sitting increases the dangers of blood clots and deep vein thrombosis.
The risks escalate if the booze interferes with ingested food or medications. Jamie outlines the repercussions on cardiac health: “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.”
He continues, explaining how indulging in alcohol up in the air can lead to worrying physiological changes: “Studies have shown that this can reduce blood oxygen levels and increase heart rate. This not only disrupts deep sleep but makes those with preexisting heart conditions more vulnerable to heart disease.”
How to minimise the risks from drinking when flying
- Drink responsibly – Avoid excessive drinking and be aware that alcohol can have a stronger effect at high altitudes.
- Drink plenty of water before and during your flight – and pair each alcoholic drink with a glass of water.
- Eat before drinking any alcohol.
- Know your limits and pace yourself accordingly.
- Respect the cabin crew – If they say you’ve had enough to drink, then follow their advice.
- Wait till you arrive at your destination to enjoy an alcoholic drink rather than drinking on the plane.
- Skip drinks if you are planning on sleeping, as alcohol can disrupt sleep.
