Cocktails at cruising altitude come with potential serious health risks.
When we have had a long day before the flight, we tend to want to relax during the flight. Some relax by drinking alcohol. While it might sound like a fun way to celebrate the start of a trip, there’s something important to consider: drinking alcohol on a plane could actually be risky. If you’re planning to catch some sleep on a long-haul flight, you might want to think twice about ordering that champagne.
What happens to your body when you are in the air?Once you’re cruising at high altitude, the lower atmospheric pressure means your body gets less oxygen. Normally, your blood oxygen levels hover around 96% to 100%, but up in the sky, they can drop to about 90% or even lower.
To adjust, your body kicks into high gear: you start breathing faster to get more oxygen, and your heart pumps quicker to circulate blood throughout your system. This works for most people, but heart conditions can make it difficult.
Things get even more complicated when you throw alcohol into the mix. According to Dr. Matthew Mosquera, a medical expert from McLean Hospital, alcohol can mess with how your red blood cells pick up oxygen. It disrupts hemoglobin, the molecule responsible for carrying oxygen, making it harder for your body to stay oxygenated.
So, if you've got your boarding pass and a drink order in mind, here are some things you might want to think about. There are a few factors that can make your blood oxygen levels drop even more on a plane:
Aging: As we get older, our bodies become less efficient at adjusting to changes in oxygen levels.
Sleeping: Our breathing naturally slows down while we sleep, and this can be even more pronounced on a plane.
Underlying conditions: If you have lung disease, sleep apnea (where you briefly stop breathing while you sleep), or heart issues, less oxygen will reach your lungs.
