Trekking at high altitude can be intimidating. If you have been considering one of these adventures for a while, you have probably heard all the horror stories already… Headaches and vomiting. Helicopter rides and hyperbaric chambers. Failed dreams and crushed egos…
Unfortunately, in Australia, if you haven’t been to high altitude before, you have no way of experiencing this environment before your trek. And this can be a massive source of stress and anxiety for both you, and your family. So, to help relieve some of this stress, this article is all about the basics. And it will be discussing some of the most common mistakes first-time altitude trekkers make and what to do instead.
Mistakes to Avoid While High Altitude Trekking
Mistake #1: Climbing Too Fast
Rate of ascent is the #1 risk factor when it comes to altitude sickness. Your body needs time to adapt and acclimatise to the new environment. If you don’t give it enough time, you will get yourself into some serious trouble…
This the single most common mistake first-time trekkers will make at altitude. And it needs to be avoided!
An interesting statistic is that people who are generally more ‘fit’ have higher rates of altitude sickness. This is not because being fit puts you at a higher risk of getting sick (as some people would have you believe) but simply because people who have greater levels of fitness want to climb faster!
On the mountain, slow and steady will always win the race. You will need to be hiking at a much slower pace than you would at sea level. You will need to be taking more breaks then you might feel like you need. But this is incredibly important to stay safe!
Mistake #2: Not Eating Enough
When you are at high altitude your appetite gets suppressed. At the same time, you are burning A LOT of extra energy in this environment.
These two factors can make getting enough energy to power your body quite difficult. This is a problem. Because if you under eat, you under fuel. And if you under fuel, your physical and mental performance will be reduced, and you will be at risk of early exhaustion (which is a big risk factor in altitude sickness!)
So, what can you do to combat this?
Well first of all, you need to force yourself to eat at EVERY meal. It might be the last thing in the world you want to be doing… but you need to make it happen!
On top of this, here are a few other tips to help you get your fuel in:
- Bring a range of energy dense, highly palatable (i.e. delicious) foods in your pack to snack on (good examples include chocolates, nut mixes, dried fruit and cheese)
- Ensure you bring a mix of both sweet and savoury snacks (to avoid taste fatigue)
- Take an electrolyte supplement which has added carbohydrates (for a super easy source of calories)
Mistake #3: Using Alcohol and Sleeping Pills A Night
Sometimes at the end of a long day of trekking, all you want to do is curl up and get a good night’s sleep. But when you are at altitude, this can be easier said than done…
High altitude insomnia is a very common condition. But please, no matter how bad it gets, don’t reach for the alcohol or sleeping pills! These are incredibly dangerous…
The single most important change your body goes through during acclimatisation is an increase in the speed and depth of your breathing. Sleeping pills and alcohol act as something called a ‘respiratory depressant’. This means they slow your breathing rate down. This will significantly affect your rates of acclimatisation and increase your risk of altitude sickness!
If you need a sleeping aid for altitude, much safer alternatives are either magnesium or melatonin.
Mistake #4: Becoming Dehydrated
Dehydration happens very quickly at altitude. This is for several reasons:
- Your respiration rate in increased (making you lose more water through breathing)
- Inhalation of dry air (your body uses a certain amount of water to humidify air before reaching the lungs)
- Exertion and heavy clothing (increasing how much you sweat)
- Increased urination (from acclimatisation as well as common altitude medications)
There are several issues with this. To start with dehydration significantly reduces your physical and mental capabilities. On top of that, the symptoms of dehydration are very similar to altitude sickness – which can cause some genuine issues on the mountain!
To combat this, you need to be regularly drinking throughout your trek.
The easiest way to judge of hydration is urine colour. Ensure that it is kept either clear or light yellow. And to do this you need to actively be drinking throughout the day and never let yourself get thirsty.
* Thirst isn’t the best judge of hydration as there is a delay between your thirst reflex and your hydration level. So, if you wait until you are thirsty before you drink water, chances are you are already dehydrated!
