Acclimatization During the Everest Base Camp Trek

Acclimatization is a process by which your body adapts to the surroundings at high altitudes. This includes adapting to lower oxygen levels and lower air pressure.

It is a way of preventing the possibilities of altitude sickness. The first acclimatization point on the trek is at Namche, 3440 meters. You need a one day’s rest there. Play with the Himalayan weather while enjoying the beautiful place.

From Namche, the trek ascends to higher points day by day. That’s why you need to acclimatize there and prepare your body for higher places. Acclimatizing in Namche doesn’t mean you no more have risks of altitude sickness.

1000 meters above from Namche, Dingboche 4440 meters is the destination for the second acclimatization. To prevent altitude sickness, you must acclimate your body in every 1000 meters ascent.

Resting your body at higher altitude means you are allowing your lungs to adjust to thinner air by itself. This will encourage a less risk and an easier journey.

In preventing altitude sickness, proper acclimatization is the most important thing to do. Skipping your acclimatizing schedule means you are increasing the risks of altitude sickness.

Some Tips to Prevent Everest Base Camp Altitude Sickness

Research on Altitude Sickness

Gather every possible information about the Everest Base Camp trek before going. Focus mainly on the possibilities, symptoms, preventive measures and remedies of altitude sickness.

Everest Base Camp trek isn’t a normal trek. The trek takes you to an altitude of 5500 meters (max). Trek in high altitudes is always difficult. Be ready to encounter newer risks and challenges as the trek progresses.

You are more likely to get altitude sickness while on the trek. Researching on the EBC trek, possibilities of the altitude sickness, and its prevention is thus, mandatory.

Getting altitude sickness is common amongst the trekkers. Even the experienced guides and trekkers can get the sickness if they lack proper preparations.

You can research about altitude sickness via various means. Consult your doctor, visit websites, blogs, and other sources for valuable information.

Choose the Right Traveling Agency

Choosing the right traveling agency means getting rid of half of your problems.

A good traveling agency provides you proper suggestions during the treks. Also, they will guide you as per their previous experiences. They will organize your trek properly.

They will schedule the most suitable acclimatization schedule for your EBC trek. They will clearly advise you about the do’s and dont’s during the trek.

While choosing a travel agency, don’t look for a cheaper rate but on the itinerary and acclimatization schedule.

During your EBC trek, you will need a professional guide by your side to keep you safe. The trek can be fatal if taken carelessly.

Walk in a Slow and Steady Pace

Walking at a slow and steady pace is one of the keys to a successful EBC trek. It helps you to prevent yourself from altitude sickness.

On the Everest Base Camp trek, the ascending paths are mostly steep and rocky. So, you must move gradually maintaining a uniform speed.

In most of the cases, trekkers who attempt speedy treks are the one who gets the altitude sickness symptoms. Hurrying up increases breathing rates. It makes your body restless.

As a result, you will suffer from shortness of breath. Also, you won’t have enough time and energy to cope with the changing atmosphere.

The low oxygen levels can cause your body to dehydrate sooner. This is when you start seeing the altitude sickness symptoms.

Hit High Altitudes During Daytime and Sleep at Lower Altitude

In general, the symptoms of altitude sickness are hardly seen during days. On the other hand, air gets thinner during days. Furthermore, the low temperature adds to it. So, you are more likely to see altitude sickness symptoms at nights.

So, it is better to trek to higher altitudes during days. Descend down to lower altitudes for night stays. It is not recommended to sleep at altitudes above 5000 meters during EBC treks.

Sleeping above such altitude means there is a risk of severe altitude sickness (HAPE and HACE). So it isn’t a right decision to stay at the Base camp, 5360m and Kalapathar, 5545m during your EBC trek.

Get Some Physical Fitness Training Before Trekking

Altitude sickness generally affects a person having weak physical and medical conditions. Regardless of age group, or gender, it can happen to anyone.

But being physically fit is a sign of a healthy body. This doesn’t prevent the sickness but can reduce its risks to some extent.

Keep Your Body Hydrated

While trekking in cold surroundings and high altitudes, your body dehydrates very fast. You will feel less thirsty, but deep inside your body tends towards dehydrating.

Thus, you might not be known but you are dehydrating. This can cause altitude sickness. So, you must drink water from time to time to stay hydrated.

Do not restrict drinking water, in order to avoid urinating too often. Doctors suggest drinking up to 5 liters of water every day during your EBC trek.

Hydrating helps you to cure the acute altitude sickness symptoms. Carry a refillable water bottle with you. Drink water in certain intervals, breaks, or during rests.

Avoid Drinking Alcohols and Smoking During the Trek

Drinking alcohol pushes your body to dehydrate. Smoking causes shortness of breath. This means you can get symptoms of altitude sickness so easily. In some cases, drinking and smoking can worsen your health conditions.

Never smoke or drink alcoholic beverages while on high altitude treks.

Never Try to Hide the Symptoms of Altitude Sickness

Throughout the EBC trek, keep in mind that you are in the risk zone. Avoid ignoring minor symptoms of altitude sickness while overestimating your strength.

You must discontinue your trek and descend down to safer altitudes as soon as you see any symptoms. If you try to ignore the symptoms, that’s when the sickness gets you badly.

Inform your team/ partner/ guide when you see any signs of the sickness. It is necessary to take steps of preventive measures to resolve your sickness immediately.

Never push your limits. Do not lie or keep quiet.

Take Immediate Medications and Other Medical Precautions

Take Energy Bars and Dark Chocolates
