I got frostbite on both my ears once. It was -40 celsius, very windy and I was outside for an hour without ear protection. My ears literally felt like they were on fire and then I looked in the mirror and my ears were like 3 times their normal size. It freaked me out. I think it took like 3 days before they shrank back to normal size and all the skin came off as they healed. They looked dead. It was nasty.
That Sherpa Documentary aired in here and was quite an eye opener. Always knew Everest has become commercial never knew what Sherpas go through. Good guy Discovery.
I swear if you Eat my wife's home made spicy chicken soup or as I call it molten penicillin I guarantee you could go bareback up Everest in boxer shorts and flip flops
When I was a kid growing up in Ohio, I use to be outside for hours in the snow just wearing gym shoes and when I would get home, my feet would be frozen solid. I am lucky I never got frost bite
+Exde if you go in the summer time, its obviously warm, but in the winter time, thats a different story. This is coming from someone who lives in northern Canada...
there seems to be a problem with the captions Dnews! sorry for this but I require ur captions for my learning (i have problems with my ear) thank you so much for posting everyday as usual, it was great learning from your uploads!
"Oxygen molecule for energy" Ok so i kinda see what you mean but that i outright wrong. We dont get energy from oxygen, why would we need to eat then. Oxygen acts as a final electron receiver in the aerobic metabolism, so it is required for maximun ATP output of 36 ATP per glucose, vs the anaerobic metabolism of 2 ATP. You also could have added that the hypoxia climbers get is also called hypobaric hypoxia since the lack of oxygen is mostly due to low pressure in high altitudes. I think at mount everest is something like 26mmHG
I'd say oxygen is the molecule for energy. Oxygen is necessary for aerobic respiration and the production of ATP (as you know) the currency for energy throughout the body. So, while oxygen isn't directly energy, it certainly a molecule for energy.
FinTheDew the pressure at the top of Mt. Everest is more like 260MMHG, not 26. And I do think it’s fair to say O2 is energy because it’s essential for aerobic respiration. Without it our digestive system can’t work, and we can’t power our bodies very well.
Yay a fellow michigander. Also this video makes me wonder how common frostbite was in northern reaches of the US from the days of indigenous rule to colonial and early American rule.
Maybe the reason that the risk for frostbite elevates dramatically when deprived of oxygen is because, then, there is not as much of it the blood and maybe that makes it harder to distribute heat
I was pretty close to lousing fingers once.. In was on a trip, and we ofcourse stayed in the cabin, but i got stuck outside when i had to get wood in around -40C maybe even less for like 20 minutes.. Two of my fingertips looked weird for like a year after that lol..
I'm in northern Maine and I had to walk across a bridge that was on a river, and it was like 30-40 below with windchill, and my brother and I were in physical pain with a full winter kit on
The temperature shown on a thermometer doesn't mean much if the air is still. What is far more debilitating is wind and damp. Temperatures around freezing-point with driving rain are far worse than lower temperatures in areas that have dry-cold and no wind. This was confirmed by contractors who had worked in Thule. Sadly the cold and wet in England caused one contractor to fall and sustain fatal injuries.
Trust me my friend, I know the pain of wind, I'm from Canada. -20 aint horrible, but when the wind blows It can feel < -40. You need to walk backwards even to go down the street.
One time I was pushed into the snow while standing still waiting for the busses at my school. It was funny the first time but the two other times I was furious and in pain because I used my gloveless hands to catch my fall. My hands were turing purple and they were going numb. I cried the rest of the way home....
SwedishPerson its quite possibly dangerous, but if you end up in hospital you do have the worlds hottest nurses, i know cos ive seen the 1990s porn films!
You don't have to climb Everest to get frostbite as you can get it at a railway station in the UK in winter. Scenario car breaks down and one's Recovery has been reduced to twenty miles so one tries to get home by train. Train terminates at a station halfway through the journey and the station closes at the dead of night. There are NO WAITING ROOMS as the accountants have done away with them. One has to wait outside for the "milk train" (the very first train in the morning) in the freezing cold wind. All shelter has been eliminated in order to discourage "street people". Four or five hours of being blast-frozen and one has a problem. Absolutely disgusting when one has a through-ticket. Three months after this fiasco a sore is still present and electrifying nerve-pain sometimes occurs. The circulation in the leg exposed to the wind has been affected and this results in calf-pain after walking a hundred yards or so. It was never like that before as I used to be able to walk for miles. Although I am not a doctor it may well be DVT that has been caused by the cold. Take Care!
We're American, it's what we use. And the reason being when at least 200,000 of us petitioned the White House to change it to the metric system, the White House commented on it, stating freedom of choice, allowing companies and individuals to use whatever system they want. So unfortunately, we Americans, are stuck with the Imperial system because too many want to be different from the rest of the world and hate change in general.
Neuker nar Bohemia And you're telling me you unsubscribed why? DNews is meant primarily for an American audiance, hence any metric unit is in parentheses. But given your attitude, it was no loss on their end. I also suggest you unsubscribe from any American RU-vid channel, because we use the Imperial system.
Hey Dnews, I want more current events and i wanna hear more about what we can do on the micro level to improve our world u teach us so much about. You guys make some of the most interesting and thought provoking videos on youtube. Such an interesting world we live in, yet we are collectively destroying it. Much love to one of my fav channels, Nathan Smith of Little Rock, AR
Unskippable ads, are the worst and ruin the video. I understand you want to earn money and I want to watch the video, but at least let me skip the video or put it at the end 😖
Hello , if anyone will see this comment , I recently just got a tiny bit of frostbite on my ankles and my lower arm. It is itchy and bumpy , I have no idea what to do about it. My parents say a little bit won’t affect you , but none of my parents are doctors , so if anyone knows what to do about it or if it even is frostbite , comment on this.-Justin
I always wondered why people cut of their limbs when they are extrem cold and on the way freezing to death but never found a good answer. Could someone explain it please?
+Sameed M No. Isnt it because that portion of your body (ex. arm) has its majority frozen and without enough blood for it to keep functioning. so by that limit amputation is necessary.
McGeek well old people usually regret not taking risks risks can make you happier trust me search up your not alive I'm not dead or something like that by Prince ea
Non-everest climber here, so do have any leisure activities that involves purchasing stuff like games or movies? Could be putting that to saving the world.
They have no respect for the purity of the mountain. They have litter everything on this beautiful and sanctity of the mountain. So yes, I don't think anyone should go there.
I got frostbite on my left hand one winter. Not very severe, I am fine now. But still. It felt like i was wearing a glove made from my own skin. It was freaky.
Wow i didn't know everest was only -20 deg Celsius. That's actually rather tiny compared to -70 at siachen where Indian soldiers maintain a permanent presence.
The captioning is bad, at some points it's too fast can't read it other times it's slower than than the picture. For us deaf and hard of hearing very difficult to follow. There is an attempt but not the delivery.
