Climbing the Mt Everest is reserved for the elite, it requires months of preparation and a lot of money, but once you've succeeded you would have the satisfaction of being at highest point on Earth... with an extra bonus.
It might sound like a dirty joke, but it is actually a thing. According to Srinath Varma, a passionate 26-year-old climber who spoke to Vice about this phenomenon, the entire blood flow slows down as you get higher on the mountain and the heart beats harder and faster:
The lack of blood flow to your brain, paired with oxygen deficiency really does make your mind go blank. You feel as though you have no retained knowledge and you start to forget how your body works—it’s scary!
When asked if he got a boner, he answered that he gets one after 4.500 meters. This phenomenon is not isolated and has a name: the airplane boner.
As the cabin pressure changes with altitude, the male penis becomes erect. The lower cabin pressure due to altitude then causes blood to flow directly to the boner region of the male anatomy. This situation is worsened if an attractive female is sitting next to him. However, screaming children on planes seem to lessen the severity of the swelling.
Climbing the Everest is a bit different than being on a plane, as the experience, we can only guess is more intense, we imagine the boner might be also more intense. When asked how long did it last Srinath answered:
About two hours per day, I think. I just had to drink a lot of water to speed up blood circulation, and also keep my body warm and constantly moving. It’s a patience game.
He also admitted it didn't make too much difference when he climbs but it's difficult to hide the third limb. But, with the lack of oxygen 'his mind was already playing tricks', so it's not a big issue. We reckon The Everest is worth the trouble.
