Altitude Sickness and Kids

At this time of the year, families across the country (and world) are taking vacations. They head to the beach, the mountains, to the lakes & the deserts.  In the United States in particular, many east coasters head west to see our National Parks, our majestic mountain ranges, and our still-wild frontier.  The effects of moderate to high altitude on children should be considered when planning your family trip to the mountain ranges of the west.

I recall quite distinctly my first trip to the Rocky Mountains of Colorado.  We flew into Denver (from PA) and drove immediately up to meet a friend at Estes Park, camping on BLM land in RMNP.  Sleep was tough to come by that first night. As I later realized, the 8,000 foot change in altitude (from sea level to RMNP) in less than 24 hours was not an example of good planning.  We should have spent the first night in Denver (around 5,000 feet) and then taken the trip north.  We didn’t.

One symptom of altitude sickness is difficulty sleeping, others are headache and nausea.  Water helped to minimize my headache and I woke up in the morning ready to get started despite a restless night of sleep (another symptom).  We hiked into the Monastery, a one hour hike down to some great sport climbing.  We carried water, climbing gear, rope, & food.  The hike in was time consuming and a bit strenuous with our gear. Activity/exertion can bring on altitude sickness symptoms and as the day of climbing wore on I found myself with a headache, some nausea and a bit of breathlessness as my body tried to adjust to the change in oxygen and altitude.  By the time we hiked out, our friend (a Denver resident) was carrying my pack and I was stopping every few feet to throw up on the side of the trail.  It was not the best start to our two week vacation.

Looking back, I know all of the things we did wrong or could have done differently and I’m glad that we had this experience so that we would remember what not to do for our next trip.  I’ve found that I’m susceptible to altitude sickness (apparently if you get it once you are likely to get it again under similar circumstances). Example: When we hiked a 14er later in the trip, (Mt. Sneffles) near Telluride/Ouray, I found myself acting confused/irrational (I ran down the mountain at a pretty fast and unsafe pace).

So what are the symptoms of altitude sickness and how can you prevent it?  What altitudes are safe for children and at what ages?  Here are some of the things I’ve found with the relevant sources linked for more information.

Symptoms:

  • Headache
  • Nausea
  • Dizziness
  • Restless Sleep
  • Shortness of breath
  • Confusion
  • Tired/Fatigue
  • Not hungry/little to no appetite

Factors that increase likelihood and onset of altitude sickness:

  • Dehydration
  • Faster you climb/ascend altitudes, more likely you’ll have symptoms
  • Live at sea level
  • Have had it before

Things to decrease likelihood/onset of altitude sickness:

  • Stay hydrated/drink lots of fluids
  • Sleep at lower altitudes
  • Ascend slowly (2,000 feet per day)
  • Avoid alcohol
  • Eat regularly, particularly meals high in carbs

Young children are unable to communicate their symptoms and many of the symptoms (lack of sleep or appetite for instance) are typical issues for young children without altitude sickness.  Because of the difficulty in understanding a young child’s symptoms, many sources recommend that children under the age of 1 should not be taken to high altitude locations (locations above 8000 feet).  Children under 3 should ascend extremely slowly and should be monitored closely for signs of altitude sickness.   There are many types/degrees of severity with regard to altitude sickness.  Become familiar with what to look for and begin descent immediately if the symptoms are severe (carrying the child so as to minimize their exertion).

  • Children can be taken to 8000 feet but should ascend past that height gradually.
  • Children who can not communicate their symptoms should be monitored closely and/or not be taken to altitudes above 3000 meters.
  • Children under 1 should not be taken to high altitudes (above 3000 meters).

General information from Wilderness Medical Society.

Studies of people at moderate altitudes (1890 – 2910 meters) indicate that altitude sickness can occur at those moderate heights so it is important to note that just driving your car to the top of Pikes Peak or any number of mountain locations can cause some level of altitude sickness in you and/or your child.  Know the symptoms and consider that children can’t (or won’t) communicate that they aren’t feeling well.  Keep them hydrated and fed, and be sure to descend (when possible) to avoid more serious symptoms.  While this post discusses primarily the symptoms of mild altitude sickness, there are many degrees of severity and variations of altitude sickness.  Click here to read more about the different types of symptoms and severity of sickness.  Here’s a research article about Acute Mountain Sickness and Pre-verbal children (for your reading enjoyment).

New River Gorge with Kids

New River Gorge Climbing Trip We finally made our way back to the New River Gorge in West Virginia for a weekend of climbing.  It has been years (pre kids) since we had been to this area as it seemed to be a bit less kid friendly than other areas that we had been to.  Our ClimbingWeather.com app was showing predictions of snow on Friday night - and it wasn't far off.  The drive took us eons, especially in the Appalachians with the travel trailer.  We … [Read More...]

Hiking in a Creek

Have you ever started out on a day hike with children only to have it turn into something completely different that what you planned?  Ha. Of course you have. Many of our adventures start out as one thing ("I want to climb X route" or "sleep at X campground". . . "I want to relax in a tube on the water", or "I want to sleep in the sand") and end up as something completely different ("The route had a group staked out on it for the day" or "I couldn't … [Read More...]

Those that know me will laugh at the irony. . . My … [Read More...]

Stand Up Paddleboarding

The best rock climbing areas tend to be located in or near wilderness, national parks, mountains, and forests.  There are exceptions, of course!  Still, when we took a family trip to the jersey shore this summer, there was no rock to be found.  As usual, my husband and I sought out something both "active" and "family friendly" to try with the kids. Surfing, Kite Surfing, Kayaking Ryan has wanted to try surfing for years, but that's a solo endeavor, as … [Read More...]

The Mount Rushmore Dilemma

Visiting Mount Rushmore with Kids Our summer trip to Wyoming and South Dakota was amazing.  We combined climbing with family time, history, geography, science and more.  When we planned the trip, climbing was the main focus, but hitting some of the National Parks and National Monuments were also a must.  Mount Rushmore is one of those locations that combines both.  There are amazing climbing opportunities in the shadow of the National Monument.  There are … [Read More...]

    Nice post. I got Altitude sickness the first 14er I ever tried. I had been living in Colorado for a few months and we even camped at 10,000 but that didn't seem to prevent it. I've learned that when I hike at my own pace and drank and eat more often it really seems to help me. It's scary to see people who just keep going when they start getting the symptoms, instead of hiking down. The mountain isn't going anywhere, you can always try again another time.Oh, and the hike to The Monastery is hot and pretty miserable whether you live in Colorado or not, if you ask me. 😉

    I'd love to see your Monastery pics if you have any! When I told Ryan (husband) that I said the hike to the monastery was 1 hour, he was like "yeah, if you knew where you were going." Apparently, it took us and hour and a half at minimum, and then we hiked around more to find a certain route. The first day we left because the weather turned (we didn't want to be the stupid out of towners who got struck by lightening out there) so we went back a second day to actually climb. That was WORK! I don't remember as well as he does because I was so SICK! Blah.

    Nice post!I have heard that not getting altitude sickness doesn't necessarily mean you won't get it again.So far I've been pretty lucky (knock on wood). I live at sea level and the first time I climbed Mt. Whitney I went from sea level to Lone Pine (not high enough for acclimation) for one night then it was Whitney in one day very early the next morning, luckily I was fine.My second Whitney trip (technical route) I did spend some time acclimating.And only last year did I realize that all my time spent climbing in the Sierras is also in the altitude sickness zone.

  4. Great post! My 3 yr old has gotten sick while driving over high mountain passes so I always try to be extra attentive to her in situations where altitude is a factor.
