How to handle altitude sickness

by ALTITUDE ATHLETIC | Altitude Training Information, Hiking, Climbing and Mountaineering

Imagine your worst hangover. Dizziness, nausea, loss of appetite, the deep desire to just lay down, wherever you are, and sleep. Now, imagine that instead of waking up in your bed after a night out, you’re three quarters of the way up a 12,000 ft. mountain, pushing yourself harder than you ever have in your life. You are experiencing the early symptoms of acute mountain sickness, (or AMS), commonly known as altitude sickness.

Altitude sickness is an illness that develops when the body doesn’t have time to adapt to the decreased air pressure and oxygen levels of high altitude—defined as any area 8,000 ft. above sea level. Symptoms include dizziness, fatigue, shortness of breath, and loss of appetite—wickedly similar to a brutal hangover.

In its most extreme cases, altitude sickness can develop into high altitude pulmonary edema (HAPE), an accumulation of fluid in the lungs, and high altitude cerebral oedema (HACE), swelling of the brain due to a lack of oxygen. Jon Krakauer provides a chilling description of Ngawang Topche, a Sherpa on the 1996 Everest expedition, experiencing HAPE in John Krakauer’s book Into Thin Air. “Ngawang was delirious, stumbling like a drunk, and coughing up pink, blood-laced froth.”

Don’t let this scare you off your planned trip to Kilimanjaro or Everest Base Camp, though. HAPE and HACE are extremely rare. They typically occur when people ignore the symptoms of altitude sickness and continue to physically exert themselves. Just be wary that if you let altitude sickness progress to this level of severity, it can prove fatal.

To ensure this doesn’t happen, follow these tips on how to handle altitude sickness.

Travel Slowly

We get it. You want to be the first one to the top of the mountain. But it’s not worth it if your group has to drag you back down. Don’t turn your ascent into a competition. By not giving your body enough time to adjust to the lack of oxygen you’re much more likely to experience altitude sickness.

According to contemporary research, age, sex and physical fitness have no bearing on a person’s likelihood to be afflicted by the illness. This means that even if you’re one of the fittest people on the planet you can still be affected, especially if you’re racing to the summit.

Before even starting your climb, it’s a good idea to take two to three days to acclimatize to higher altitude. Avoid flying directly into high altitude areas, though. Travel to the destination progressively, acclimatizing as you go.

During the climb, take it slow. Enjoy the view. If you’re hiking with porters or Sherpas, follow their lead. They know the mountain well and will know when it’s best to take a rest. If you’re climbing alone, don’t ascend more than 500 metres a day. After every 900 metres, or three or four days of climbing, take a rest day to avoid overexertion.

Remember, it’s not a race.

Stay hydrated and fed

Dehydration is a major cause of altitude sickness. In part, because high altitude has a diuretic effect on the body, causing you to pee…a lot. And with all the hiking you’ll be doing, you’re going to sweat out liquids fast. Take some hydration salts with you and toss a hydration pack in your bag that you can sip on during the hike. It’s better to carry too much water than not enough.

And just to clarify, no, beer doesn’t count as a liquid. Alcohol dehydrates you and can accelerate the altitude sickness. Save the liquor for the bar. Instead, bring water or sports drinks like Gatorade.

Altitude also tends to rob you of your appetite, slowing down your digestion. To have enough energy to hike each day, eat more than you feel is necessary. Oatmeal is a good idea in terms of meals, especially if you add some nuts and berries. And bring snacks for the climb. Munching on a chocolate bar along the way may give you the energy you need to make it to the summit.

Treat Symptoms immediately

As mentioned earlier, if not treated, altitude sickness can evolve into worse illnesses like HAPE and HACE. If you are feeling the onset of symptoms, stop and rest. Wait a day or two until the symptoms have completely receded before continuing to climb.

Proactively, you can take Diamox one to two days before starting your climb. The medication reduces symptoms and eases your adjustment to altitude. If you’re still feeling the effects while climbing, try combatting headaches with ibuprofen and Tylenol. And promethazine can work wonders when feeling sick.

If you’re still exhibiting symptoms after 24 hours, turn around and start to descend. Once down at the base, the symptoms should dispel after two to three days. Don’t try ascending to high altitude again until the symptoms are completely gone.

Train at Altitude

Before leaving for an expedition, mountaineers can pre-acclimate and prepare for high altitudes by sleeping and exercising at simulated altitude. This is a great option if you live at sea-level and can’t easily access the mountains.

Simulated altitude training is exercising in or breathing air with less oxygen to replicate the thinner air you find up in the mountains. Simulated altitude is created by decreasing the percentage of oxygen in the air below 20.9% oxygen (the amount of oxygen in the air at sea-level). There are two strategies for altitude training: Live High, Train Low and Intermittent Hypoxic Training. Both methods have been shown to improve performance in recreational and professional athletes, and those travelling to high altitudes.

Live High, Train Low

Doing sedentary tasks at altitude for longer durations, i.e “Living High”, while training at a lower level, can stimulate erythropoiesis (the process that produces red blood cells).

Sleep tents and larger altitude tents can be set up at home, so you can get 6+ hours of high-altitude exposure and then be back down to sea-level in seconds. Simulated altitude training can lower the age of red blood cells and increase hemoglobin mass (hemoglobin is an oxygen-carrying protein). These changes in the blood can help reduce and prevent symptoms of altitude sickness.

Intermittent Hypoxic Training

Intermittent Hypoxic Training (IHT) is living at sea-level and exercising at altitude. If you’ve got a stationary bike or treadmill at home, you can use a simulated altitude training mask to breath hypoxic air while you’re training. Otherwise, there are special gyms that can actually simulate altitude with no masks needed.

Go to top

Finally, if you’re experiencing symptoms – tell someone. Your travel companions are there to help and will have clearer heads to assess the situation.

While it is a hindrance, if you monitor and treat the symptoms appropriately, altitude sickness should not be the reason you miss making it to the summit.

5 Tips To Prepare for the Trek to Everest Basecamp

by Altitude Athletic | Altitude Training Information, Hiking, Climbing and Mountaineering

Are you planning to trek to Everest basecamp? With an altitude of 5,364 meters (17,598 feet), the Base Camp is the starting point for mountaineers who are attempting to climb the world’s highest mountain, Mount Everest. But you don’t have to be a mountaineer to experience the magic of the Everest Base Camp trek.

Whether you’re a seasoned hiker or a beginner, it’s important to prepare your body for the physical demands of this challenging journey. So get ready to lace up your hiking boots and learn how to prepare for a journey to the roof of the world. Here are some tips for training:

Build endurance: Trekking to Everest basecamp involves long days of hiking at high altitudes. If you have access to a simulated altitude environment (like an altitude chamber), doing your cardio sessions in this environment would be an ideal form of preparation to build endurance and increase aerobic performance. Training at simulated altitude will help you resist fatigue and maintain high energy during long hikes. If you do not have access to a simulated altitude environment, you can focus on building your endurance by going on longer hikes or walks, gradually increasing the distance over time.
Train with a backpack: You’ll be carrying a backpack with your essentials, so it’s important to get used to the weight. Start by carrying a light backpack and gradually increase the weight as you get stronger.
Get outside: Incorporating outdoor hikes into your training plan is a great way to prepare your body for the challenging weather conditions and terrains you may encounter on the trek to Everest basecamp.
Pre-acclimatize: Altitude sickness is a concern when trekking at high elevations. The trek to Everest basecamp takes you through a range of elevations up to 5,364 m. Longer duration exposures to simulated altitude can help prepare your body for the thin air. Long exposures create hematological adaptations (changes in factors in the blood), which can help reduce and prevent symptoms of altitude sickness. Hematological changes can also further improve delaying fatigue while at high altitudes.
Work with an expert on a training plan: Hiking uphill and downhill for several hours a day can be tough on your legs. Good balance is important when dealing with unstable terrain while fatigued. And stamina is critical on long hiking days. A good coach can make sure you’re well trained for each of these factors – cardio, strength and balance – before you leave. The duration of your training plan will depend on how much time you have to prepare and where you’re currently at physically. But in general, it’s recommended that you start preparing at least 3 months before your trip.

4 Common Misconceptions about Altitude Training

by ALTITUDE ATHLETIC | Altitude Training Information, General Fitness

Altitude training has been around for a while – ever since the 1968 Mexico Olympics. Despite its long history, it remains relatively unknown, especially here in North America. This is because altitude training has been used only exclusively by the pros. Only recently has the technology become more accessible to everyday athletes. Because of how elusive it is, we have come across some misconceptions about altitude training. Here are 4 of the most common ones we’ve heard:

1. It’s only for people who are planning to race at altitude

No, altitude training is not just for people competing at altitude. It’s also for people looking to improve their athletic performance at sea level, specifically increase their VO2 max, aerobic capacity and power output.

Look at it like resistance training, but for your endurance. Reducing the oxygen percentage in the room is like adding resistance to your workout. And building that kind of training into your program will improve (or at the very least, maintain) performance at any elevation.

2. Altitude training is dangerous

We commonly get the question – “Is altitude training safe? There are risks associated with any form of physical activity – whether it be hot yoga, a high intensity spin class, or a run around the neighborhood. The same goes for training in a simulated altitude environment. To reduce risk as much as possible – members are assessed and screened before entering the altitude room. During training, members are given carefully regulated programs based on their conditioning. Additionally, members are always under supervision from trained coaches. Heart rate monitors and pulse oximeters are used regularly to monitor exertion.

Of course, not all forms of exercise are safe for everybody. And altitude training isn’t recommended for people who are pregnant, have breathing problems like asthma, have high blood pressure or other serious medical issues.

3. But I’ll lose strength and power exercising at altitude

Training in reduced oxygen typically means you are unable to reach the same levels of ‘intensity’ as you can at sea level. It is this stress of hypoxia on the body that stimulates it to be more efficient in using oxygen and providing energy to active muscles, improving aerobic conditioning and endurance. Continuous exposure to high altitude will cause you to lose power. But, when you combine simulated altitude training sessions (2-3 per week) with your regular strength and power sessions at sea level – you can maintain, and actually boost, your strength and power levels no problem.

4. I’ve heard that you are supposed to sleep in an altitude tent. Why exercise?

Altitude tents are designed for the “live high, train low” model. This method of training (sleeping at altitude) is commonly used by athletes to increase their red blood cell count and improve overall performance.

For those of us living at sea level, and who aren’t professional athletes – altitude tents can become impractical. We don’t have the benefit of naturally ‘living high’ and it can be hard to get the most out of an altitude tent – which you should be using for 4 weeks, 16 hours/day while maintaining training. See here.

A great alternative is simulated altitude training, which follows the “live low, train high” model. You already live low, and perhaps mostly compete low. Training high gets the job done quicker (2-3 sessions per week is usually recommended) and it’s much easier to convince your partner about heading to the gym than sleeping in a tent.

Altitude Training Rooms – The Evolution

by ALTITUDE ATHLETIC | Altitude Training Information, General Fitness

Altitude training, once the secret weapon of elite athletes, has evolved dramatically over the years. The concept of training in reduced oxygen environments to enhance performance has a rich history dating back to the mid-20th century. Today, altitude training rooms, often referred to as hypoxic chambers, have become accessible to a wider range of athletes and fitness enthusiasts. In this blog post, we will explore the evolution of altitude training rooms and how they have revolutionized the way athletes prepare for peak performance.

The Early Days of Altitude Training:

The history of altitude training can be traced back to the 1940s when it was first used as a method to improve athletic performance. Initially, athletes had to travel to high-altitude locations to benefit from the reduced oxygen environment. These high-altitude camps were remote and often inconvenient, making altitude training accessible only to a select few.

The Emergence of Hypoxic Chambers:

The next major development in altitude training was the creation of hypoxic chambers or altitude training rooms. These rooms, equipped with specialized equipment, allow individuals to simulate high-altitude conditions without leaving the comfort of their training facilities. This marked a significant shift, making altitude training more convenient and accessible.

Altitude Training Rooms Today:

Modern altitude training rooms have come a long way from their early iterations. They are now equipped with advanced technology that allows for precise control of oxygen levels, temperature, and humidity. Athletes and fitness enthusiasts can customize their altitude training experience to suit their specific goals and training regimens.

Benefits of Altitude Training Rooms:

Enhanced Endurance: Training in reduced oxygen environments helps the body adapt by increasing red blood cell production, leading to improved oxygen-carrying capacity and enhanced endurance.
Faster Recovery: Altitude training can accelerate the recovery process, allowing athletes to train harder and more frequently.
Increased Stamina: Athletes can build greater stamina, vital for endurance sports, by incorporating altitude training into their routines.
Mental Toughness: Altitude training not only enhances physical capabilities but also strengthens mental resilience, a key component of success in sports.
Accessible to All: With the availability of altitude training rooms, this powerful training method is no longer limited to elite athletes and is accessible to individuals of all fitness levels.

Conclusion:

The evolution of altitude training rooms, from the early days of high-altitude camps to the advanced hypoxic chambers of today, has revolutionized the way athletes prepare for peak performance. These rooms offer a controlled and convenient environment for athletes and fitness enthusiasts to harness the benefits of altitude training. As technology continues to advance, we can expect even more precise and effective altitude training methods in the future. This technology will help individuals push their physical and mental boundaries to achieve their fitness and performance goals.
