This Is Why It's Always Freezing Cold On Airplanes

By Hollie Borland

If you're heading abroad to catch the sun in your shorts and tee but you're always caught out by those freezing cold temperatures on the plane, then this is when.

Right, it's the day you've been waiting for all year. Shorts on? Check. Flip flops on? Check. T-shirt? Got it. You are so ready to hit the pool the moment the plane lands on the run way. You're heading abroad on holiday. You're ready for the sun.

You've checked in your suitcase and you're traveling light with your hand luggage. Armed with your duty-free spoils, you board the plane and settle down in your seat. It's warm and comfortable. 

Then the plane takes off and when you're cruising along horizontally it strikes you like a slap in the face. The air conditioning covers your skin in goosebumps as the relentless blasts make you regret your decision to travel beach-ready.   

And you're not the only one who's noticed it. Up and down the aisles, you see cabin crew frantically answering the attendance bells, handing out scratchy blankets to travellers encased in ice cubes. 

What can't they just turn the heating up? Why? WHY?

Funny you should ask that. In short, the answer is they can't.

A study by ASTM International found that humans are more likely to faint on airplanes than on the ground thanks to hypoxia. This condition causes people to pass out because their body isn't getting enough oxygen, often experience by flight passengers when they're at altitude. 

According to the study "airline passengers may become considerably hypoxic due to reduced pulmonary ventilation caused by immobility, drowsiness, and gastro-intestinal distension."

Being at high cabin pressure can trigger it and so can warmer cabin temperatures. 

So, while most people wouldn't faint in warmer temperature on a plane, there will be some who do pass out and let's be honest, the airline companies aren't willing to find out which of us are more likely to suffer from it. 

The study isn't new, but bear your newfound knowledge in mind next time you're flying. 

After all, you are off on holiday.
