  • Hey there!

  • Welcome to Life Noggin!

  • It's a bird!

  • It's a plane!

  • No, it's a plane!

  • Got it!

  • Figured it out!

  • Airplanes are pretty amazing if you think about it.

  • In just a few hours, a giant metal bird can transport you across entire continents.

  • But anyone who's traveled by plane knows it comes with many downsides.

  • Cramped leg room, babies crying, germs, bad WIFI

  • But, while it's not something I would want to do for a long period of time, there are flights that last almost an entire day.

  • Begging the question: what would one of these flights do to your body?

  • While most flights take only about 2 hours, the number of long-haul flights lasting over 12 hours is growing.

  • And recently, engineers have built a plane able to stay in the air for 20 hours non-stop.

  • And a new flight has gotten close to this limit.

  • In October 2018, passengers on-board Singapore Airlines flight SQ21 from Newark, New Jersey to Singapore made history by participating in the longest non-stop flight ever recorded, clocking in at about 18 hours and 45 minutes.

  • But sitting on a plane for that long has to come with some consequences.

  • While major medical issues are not common on typical flights, some aspects of the airplane environment can have a negative effect on health, especially on longer flights.

  • For instance, cabin pressure, oxygen saturation and vibrations can cause nausea.

  • And the lack of humidity measured on long-haul flights, often less than the set standard, can result in dry eyes, throat, and skin.

  • One 2005 study found that the oxygen levels were also insufficient, measuring levels that would normally prompt doctors to administer supplemental oxygen.

  • Remember the cramped leg room?

  • Well, it turns out that sitting for long periods of time can cause blood clots in your legs and swelling.

  • Long flights have also been found to increase the risk of blood clots in the lungs, possibly due to mild dehydration.

  • And if that doesn't deter you from flying, wait until you hear about the radiation!

  • Since you are at a higher altitude where the air is thinner, you are more exposed to the cosmic radiation coming from the sun.

  • And your exposure amount increases depending on how high you are, how long the flight is, and how far away you are from the equator.

  • Some studies have even raised concerns about the effects of radiation on individuals taking long-haul flights, especially aircraft crew members.

  • In 2000, researchers at the Institute for Protection and Nuclear Safety measured average radiation doses on flights lasting over 3 hours ranged from 3 microsievert per hour to nearly 10 microsievert an hour, depending on the latitude in which the plane was flying.

  • Because these numbers are above the recommended limit of 1 microsievert a year set by the International Coalition of Radiological Protection,

  • the study's authors urge airlines to record radiation doses for each crew member and assess their exposure.

  • I don't know about you, but I think I'm just gonna stick to road trips for a while, or teleportation because I can do that.

  • This is the animation world.

  • So do you like flying?

  • Or do you have a fear of it?

  • Would you ever take a long flight like this?

  • Let me know in the comment section below.

  • Curious to know how you might be able survive a plane crash?

  • Check out this video.

  • Before a new aircraft ever leaves the ground, manufacturers put the model through tons of tests that look at things

  • like extreme heat and cold, high winds, excess water, ice, and lightning strikes.

  • As always, my name is Blocko, this has been Life Noggin, don't forget to keep on thinking.
