Flying Tips: Never Drink Alcohol On Flights, Here's Why
A study has highlighted the health risks associated with drinking alcohol during air travel. Researchers found that consuming alcohol in an aeroplane can cause serious heart issues. This research was published in the medical journal Thorax.
Many people enjoy drinks offered by airlines during flights. However, this can pose health risks, especially on long journeys. The study revealed that drinking alcohol and then sleeping on a plane can reduce blood oxygen levels and increase heart rates. This is due to the decreased air pressure in planes.

Impact On Health
The research included 48 healthy individuals aged 18 to 40 years. They were divided into two groups. One group drank alcohol on the ground, while the other consumed alcohol during a flight. The results showed significant differences between the two groups.
| Condition | Blood Oxygen Saturation | Heartbeat |
|---|---|---|
| Drank on the ground | 95% | 77 bpm |
| Drank during flight | Less than 85% | 88 bpm |
Health Implications
The US Centers for Disease Control and Prevention states that healthy people typically have oxygen saturation levels between 95% and 100%. Levels below 90% are concerning and increase the risk of heart damage.
Scientists warn that drinking too much alcohol during flights can lead to life-threatening conditions, particularly for elderly passengers and those with pre-existing conditions. They recommend that such individuals avoid alcohol during air travel.
