Avoid Altitude Illness While Exercising Decreased Availability of Oxygen. As you move from sea level to higher altitude the air pressure decreases and your Dehydration. While the reduced availability of oxygen is the primary reason that exercising at altitude is more Heat Illness. Summer in.His advice: take the first couple days at altitude especially easy.
Understand—and accept—the fact that the altitude decreases your aerobic abilities and dial back your training plan.Best natural remedies for altitude sickness: Take time to acclimatise. The people that I met around south America who were most commonly caught out with altitude Try to sleep at lower altitudes.
High altitudes are a big sleep stealer. Low oxygen levels.Avoiding Altitude Illness The most important and effective way of avoiding all forms of altitude illness is to ascend gradually. Even before you get to.If you want to prevent altitude sickness, try to ascend to higher altitudes as slowly as possible, since you typically need 3-5 days to adjust to heights above 8,000 feet.
Do not go above 9,000 feet in altitude in one day.Prevention of Altitude Sickness Not surprisingly, managing altitude and ascent is key to avoiding altitude sickness. If you do this effectively, your body can adjust its physiology to run on rarefied air.
Acclimatization: It’s remarkable how well we can adapt to altitude, if we give our body time to do so.Slowly acclimating greatly helps to prevents altitude illness, improves sleep, and increases comfort and well-being. Try only increasing your altitude by 1,000 feet (305 meters) per day and plan to take rest days along the way. 2.
If you walk, hike, or climb over 10,000 feet, only go up an additional 1,000 feet per day. For every 3,000 feet you climb, rest at least a day at that height. “Climb high and sleep low”: If.Avoid over-exertion for 1-2 days after arrival to altitude.
Acetazolamide (Diamox®) taken 24 hours prior to arrival to altitude and the first 2 days at altitude is 75% effective in preventing AMS. It speeds up the acclimatization process in the body, stimulates breathing, raises blood oxygen and increases urination.If you cannot drop down by 1,000 to 2,000 feet, a portable hyperbaric chamber can help simulate a lower altitude.
You can also improve oxygen saturation with 2-4 liters per minute of oxygen. If nausea is a problem, there are antiemetic medications a doctor can prescribe.Acclimatization prevents altitude illness, improves sleep and cognition, and increases comfort and well-being, although exercise performance will always be reduced compared to what it would be at lower elevations. Increase in ventilation is the most important factor in acute acclimatization; therefore, respiratory depressants must be avoided.A related illness, high-altitude pulmonary edema (HAPE), can occur with or without warning symptoms that signal altitude sickness.
HAPE causes fluid to enter the lungs. A type of altitude sickness called high-altitude retinal hemorrhage (HARH) can cause eye damage. Coma and death are the most serious consequences of altitude sickness.Practice kappalabhati, because it pumps up your oxygen level quickly.
But do not use Ujjayi in this pranayama. Do short, sharp exhales, with a relaxed minimal inhale after each exhale, for 75 to 100 pumps. Then inhale deeply once, holding for as long as it is interesting.
A simple breathing exercise that could prevent altitude sickness which could also help dementia and autism.Drink plenty of water to reduce the risk of altitude sickness. If the ascent takes place on a remote mountain, it is important to be prepared.

Excellent job explaining this. Thank you! Can you also do one on Hypothyroidism?
I’d like to learn on Panic disorder exercise. If you can share any videos or guidline, I would appreciate it very much.
Can some one tell me at which part he explains acclimatization?
I used to live at elevation greater than 2500 m. When I descended to sea level I felt that the air is dense and somewhat uncomfortable but I acclimatized to it after 14 weeks. Why did this happen? I am supposed to feel more comfortable at sea level because there is more oxygen but what happened to me during those 14 weeks was the opposite.
You really honest this really helps me and the exercise helps me because I am currently 9000 feet high from the capital in South America also this really helps my breathing pattern it helps me a lot thank you
Can anyone tell me. I’m in a debate. At high altitudes, fighter jets, mountain climbs. Is it anything like being suffocated by choking. At that height, do you pass out or suffocate
still didnt understand why high altitude causes cerebral edema. Hypoxia in the lung causes shunting, in the brain too?
Great vid. Have you every heard of chewing coca leaves to tackle altitude sickness? Apparently the incas used it for a long time https://youtu.be/VzUZAnOVVJo
Best explanation!
Someday I might die but this glorious slide will remain forever hopefully..
It will remain forever.
I’m not sure if amount of oxygen changes with height or the lower partial pressure of oxygen is the case ��
Great content! Cheers from Poland!
Thank you I was born in sea level city and always have high altitude signs. I hope it work
Can this work if you practise it 2 weeks before trekking? I’m planning to trek but i didn’t know about it before
If you live or used to live at elevation greater than 2500 m (8202 ft) like me then give me a like.
I have RA. I live in western WA. I went on a trip to Spokane in eastern WA. I had much less inflammation in Spokane. Why would that be?
Yes, the rich people need to stop trying to climb Mt Everest. Your money won’t change your physiology. Also, good job sneaking those jokes in. ��
Very informative video. Just wanted to clarify one thing though. Is it a bad idea to sleep at higher altitudes primarily? It wasn’t entirely clear in the lecture.
I agree with tanvirul. The atmospheric pressure at the top of Mount Everest is just about half that at sea level. Therefore If the atmospheric pressure is 350 and o2 is still 21 percent then 350 x.21 is 70 Therefore a partial pressure of oxygen of just 70 before the gas is inhaled. That is already less than a normal pao2 on blood gas. By the time it gets to the alveolar capillary membrane the pao2 is maybe 35. Clearly a pao2 of 35 is no where near enough pressure to saturate hgb. In fact according to the oxyhemoglobin dissociation curve a sao2 of 90 correlates to a pa o2 of 60 and then the steep part of the curve manifests and small decreases in pao2 cause major decreases in sao2
Thanks Ninja Nerd! This playlist really helped me alot to understand respiratory physiology. Actually you are my physiology teacher �� I barely get a thing from lectures in university
Have gained alot, love ur way of teaching, LOVE from Pakistan❤
I’m in the process of making a video about various breathing techniques that may help for altitude including the wim hof method. I’ll add this one to the list!
Thanks I’m going to try this as I’m heading to the alps in 7 weeks
man i cant express how much i love you and ur videos i cant imagine med school without u!!!
This was so informative but still comprehensive the way you broke each process down. I especially appreciated the diagrams you drew as you were lecturing. That really helped me to better understand each process. I took two semesters of anatomy and physiology (AP), and I understood and learned far more from just this one video of yours than I ever did from my AP professor on a given topic. Thanks so much for the great video!
Is it possible that covid is this sickness? Can 5g disrupt the regular breathing process?
i’ve been practicing yoga breathing exercises for years & swear by it. start out w/the tibetan 5 rites in the morning & breathing exercises.
is it possible for excessive HAFE to damage internal organs?
This is solid content! Great info, great edit! Glad I found you!
Thanks Ninja! I downloaded it all. Lot of my colleagues also watch ur videos. Keep dodoing them:)
I’m moving to Vegas soon. I planned on training in the mountains three days a week at about 8000 feet, but I would be sleeping in the city, which is 2030 feet. Would that be ok for my body? I’d also like to be hiking up to the 11,000 peak for fun. How often would you recommend?
I feel like thats what I have only Im not on a mountain!!! What do I do?? Is it the virus?
Thank you sir. For explaining everything in huge manner.����
But in one of your videos you said that hyperventilation converts to normal ventilation once the body needs are met. Then is this situation due to altitude??
Thank you so, SO much for putting up comprehensive info and making physiology easy to understand.
You guys are such gems!
lol ‘what dat mean man’
Keep the excellent work going. Your channel is brilliant, helping so many medical students throughout the world
Thank you ninja nerd ��
This video help me to understand the lecture that take it PhD student thank you teacher.
This pandemic is also described as high altitude sickness and more pressure related than pneumonia could you do some explanation of individual treatments for each stage of this sickness with meds per stage? Pls
can I please know the name of that enzyme you said which can’t be hydroxilized? Thank you
Wow, man, your explanation is so incredible! A million thanks!
I recently summit Mt. Rainier. This breathing exercise helped me to breathe easier at high altitude and didn’t even feel any symptoms of high altitude sickness. I did 200 to 400 a day for couple months before climb date. I highly recommend this if you are planning to climb mountains higher than 11,000 feet.
Thank you for making this video. I could’ not have summit without this exercise.
DANG!! What a great video! I am new to the channel. Have you ever looked at the effects of freediving and breath holds? There are some pretty CRAZY physiological changes that happen especially at depth. I’d love to see a video by you in this topic. ������
I would like to know how to create angiogenesis for better faster running. Can you have a tutorial on this topic?
Excellent detailed video/explanation on high altitude medicine and physiology!!!
I see ninja nerd acknowledged the mistake and I must say his videos are still great
I’m planning to go to annapurna circuit on March 2020. The main goals are to go to Tilicho Lake first and then to Thorung La Pass. I was thinking to take jeep to Manang and start trekking from there (to save time, because can’t leave my job for too long). Is it safe for us to sleep in Manang? Or should we start lower, say at Chame or Pisang? And how many days does it take for us to acclamitized at Manang?
If trying to aid ones brain, to offset damage are there any changes you would recommend? The 30 plus 3 progression sounds doable. Although balance issues means it’s necessary to lightly lean against a wall with ones back, that should be ok?
Please can you explain How Acetazolamide can reduce cerbral edema.
born and raised at sea level for 31 years. im heading on my first backpacking trip. its 8 days long. and the highest peak is 1,030 meters. i should be perfectly fine right, thats not high enough to effect the body?
this was an awesome video. it really helps make sense of peoples mountain climbs. ive allways wondered why people go up and down Everest like 5x before they even attempt to the summit. thanks for another awesome video.
I do have a question…Could Pernicious Anemia have something to do with this? in your explanation it sounds like it might. Just wondering as I have been diagnosed with that.
OMG…! Now I know why I feel this way going up in elevation. I feel pressure in my chest, my heart starts pounding, I feel dizzy, nausea, throat feels restricted. Scary..I guess i’ll have to find another way to grandma’s house! Thank you Thank you!
i have an idea why don’t you creat a small mcq of 10 question after each lecture this will boost things for us thank u
The beginning is incorrect. The percentage Oxygen within the atmosphere remains approximately constant, even at high altitude. What changes is the atmospheric pressure (i.e. the absolute amount of air in a given volume), and for that reason even though the percentage oxygen is still around 21%, as the absolute amount of air for a given volume is lower, the partial pressure of oxygen is lower.
Why edema occur in brain, there is vasodilation in brain right due to hypoxia?
When we ascend partial pressure of oxygen does not decreases. One who decreases is total atmospheric pressure.patrial pressure remains same or sometimes changes slightly
Dear Sir thank you very much. I started doing your exercises before one month & was doing 200 reps as you said before I went on work to a very very remote place where no tourists or trekkers go, that is approx 5600 meters in Himalayas & was absolutely fine. Even i could do push ups in snow & did skipping and I was absolutely fine.
You have helped me so much that I can’t possibly thank you enough.
Amazing job ������
Greetings from Greece
Would you produce lactic acid from being hypoxic? If so does that change anything with how the body will try to compensate?
Thank you so much for this pranayama.. how sacred that a yogi shared his precious knowledge with you and now you are paying it forward. God bless you. I am going to Mount KAILASH next year and though I practice pranayama every day this one is excellent. I am grateful to you. Om
I think it is also important to mention the increase in 23 bisphospoglycerate at high altitude
There is also another important mistake. In fact the partial pressure of carbon dioxyde in the atmospheric mixture (inspired gaz) is below 1 mm Hg (0.04% of the gaz mixture). And even if it is true to say that this absolute partial pressure is lower in high altitude, it is negligible! The respiratory alcalosis is real, but it is the result of the hyperventilation induced by the hypoxemia that you describe in detail in you video, not by the diminution of carbon dioxyde in the inspired gaz.
Thank you very much brother
I has recently discovered your channel, yes i mean it, it is a discovery!
This video is not the only video I watched in your channel, it is obvious that you are a high IQ man ما شاء الله.
There are many things you were astonishing in the way you introdeuced them, among which i was very amzed in etymology, actually i used etymology late in the med school… but i think it is very important.
Excuse me,,,
The first thing changed in high altitude is not the FIO2, what decreases is the PIO2.
The FIO2 which is the fraction of air comprised by O2 is not changed in high altitudes, it remains constant, i.e approximately 21 %.
However PIO2, which is given by the folowing equation, decreases:
PIO2 = FIO2 x (Pb 47 mmHg), where FIO2 is the fraction of oxygen in inspired air, Pb is the barometric pressure, and 47 mmHg is the vapor pressure of H2O at 37°C.
The PIO2 is directly affected by the barometric pressure ( which i think is the hallmark change in high altitude, because of decreased weight of air above the measuring unit ).
You’re good. Explained very nicely and effectively.Helped a lot
I’d like to learn on Panic disorder exercise. If you can share any videos or guidline, I would appreciate it very much.
Awesome video! Super informative and I love the editing with the cartoon guy! ��
Thank u so much
Today I have done very well in my exam
In ur debt sir������
What fabulous video!!
I just miss understood some last points:
-Vasodilation (systemic circulation) triggers a high blood flow into the cerebrum and leads the cerebral edema??
-Vasoconstriction (pulmonary circulation) leads high blood flow to the lungs and produce the Pulmonary Edema??
Thank you!
I have gotten AMS twice and in both cases I had overexerted myself significantly while at altitude. I will never forget it…chills, confusion, no appetite, and a general feeling of just wanting lay down and not move. I am in much better shape now and want to try San Gorgonio (11.5k) and White Mountain Peak (14.2k). I am going to take it very easy and slow once I get above 9k
Great info, besides acute mountain sickness there is also chronic mountain sickness (Monge`s sickness) wich was identified in the 1930`s. Its ethiology is thought to be because of prologned polycithemia the blood viscosity increases and therefore less pulmonary perfusion.
thank you so much you:) are amazing! keep the great work fighting!!
Loved this! I’ll be taking pathophysiology classes next year in my nursing studies. You make learning fun and easy to remember with your upbeat style! Keep it up:)
Thank you so much sir. I have watched your every video related to respiration series and then gave reading to gyton. I want to tell everyone that it made my concepts crystal clear I definitely suggests everyone to grab your pen and register and make notes guys it’s definitely gonna work trust me. Anyhow thank you sir again��
First time hiking on a high elevation I went to Mt. Baldy Summit (10k ft elevation) last Sunday. Before reaching the summit, I start having this massive headache (like a hangover) and wanted to throw up. My hiking pace went from normal to really slow like tip-toeing lol. Some hikers noticed and asked if I’m ok. Thank goodness I reached the summit. From there I ate granola bars and slept for 2 hours. Thinking sleeping would take out the headache but it gets a lil bit worse when I woke up. Despite the situations, I still managed to descend.
Ur info is so practical
So many other vids have tips we already know
Keep iy up bro!
Beautiful content! But do change the mic system,to cut out the room booming kind of sound.Hope u grow!
Why is your t shirt having holes?? Btw good video keep up the good work man. Cheers!
Great video, but did you not miss the brachiocephalic trunk from the aorta?
You just explained all of the key points of the 1 hour lecture I sat in today, and made it much easier to follow…Great video
Chase I tried mont Blanca last year and the altitude sickness finished me at the gouter hut, where abouts could I acclimatise in the Chamonix area safely
so, here is a question / concept that i’ve been having trouble with: doesn’t increase pH left shift the Oxygen dissociation curve (Bohr effect)? why in this case does it shift to right? i get that the body is in hypoxemic state etc…
I am 64 do not smoke anything and about 4 years ago noticed I feel fatigue visiting my grandchildren who live at 2400 feet. I was born and have always lived about 200 feet altitude. Thank you for help.
You can increase the pO2 just by hyperventilation when there is konstant pO2 in the air?
thank you so much. I am going to trek to ebc soon and was looking for some exercise to prevent altitude sickness. Will let you know if this work
I have no idea whats “High Altitude Illness” until I experienced it last Sunday.
First time hiking on a high elevation I went to Mt. Baldy Summit (10k ft elevation) last Sunday.

Thinking sleeping would take out the headache but it gets a lil bit worse when I woke up. Despite the situations, I still managed to descend.
Next time if I’m hiking on a high elevation, I should bring Tylenol as a backup. Thank you for this video now I know whats “High Altitude Illness” is all about!:D
My friend’s bro died due to hape while he was trekking himanchal pradesh
��
Am I the only one that developed a crush for her just by her voice and knowledge?
Youre wrong at 1:35. People die in colorado quite frequently from altitude sickness at those measely mile high altitudes and I got altitude sickness from driving to Vail from Salt Lake City in a day. I had a “hangover” for 3 days when i got there. Luckily my friend knew what was up and made me lay around for a few days.
what if you transfer to work at high altitude 2000 m is it dangerous to your body or it can acclimate?
Does anyone know why coca leaves helps altitude sickness? https://youtu.be/VzUZAnOVVJo
