What Is Altitude Sickness?
Altitude sickness is a physical discomfort that usually occurs when visiting a place located at a higher altitude, such as Cusco, on the way from Arequipa to Colca Canyon, Huaraz or Puno.
Did you know that the alternative rainbow mountain Palccoyo is in Cusco at 16,076 ft. (4900 m)?
Most travellers who are affected by the altitude sickness in Peru are those traveling by plane, coming from a place with higher temperatures and lower altitude. This is due to the abrupt changes in altitude and climate as the air is thinner and the weather is colder.
What are the symptoms of altitude sickness?
The majority of people usually get altitude sickness between 6 and 24 hours after having reached altitudes of more than 3000 m.
Some of the typical symptoms of altitude sickness are:
- nausea and vomiting
- breathing difficulties/shortness of breath
- loss of appetite
That doesn’t sound like great holidays, does it? The average duration of the altitude sickness is around two to three days. This is normal as the acclimatization time for a traveler in Peru is approximately two days.
But don’t worry, there is always a solution. In this case, proper preparation is key.
There are certain tips to avoid the altitude sickness. These tips are recommendations from locals and past travellers who enjoyed a great (or not so great) time in the Peruvian highlands.
Avoiding the Altitude Sickness in Peru and Its Symptoms
Some of the most common pills to prevent and to treat altitude sickness and its symptoms are the following:
- Acetazolamide (sold under the name of Diamox) to prevent and treat high altitude sickness
- Altitude sickness pills (f.e. Sorojchi pills, sold in Peruvian pharmacies)
- Ibuprofen and paracetamol to treat headaches
- Gravol or Promethazine to treat nausea
You should take Diamox or Sorojchi pills to prevent the altitude sickness 1-2 days before going up in altitude. However, you should still be careful and go up in altitude gradually without rushing it.
If you feel like you are getting the symptoms mentioned above even though having taken medicine, it’s recommended to rest or go down until feeling better. The pills are available at every pharmacy and the staff at your hotel/hostel will also be able to help you out.
We recommend getting them before traveling to high altitudes so that you can prevent the symptoms as much as possible. Furthermore, talk to your doctor before traveling for personal recommendations and read all the instructions thoroughly.
In Cusco you’ll get coca tea at every restaurant or hotel/hostel. Besides that, just chewing on the leaves will help you deal with the altitude as well.
Drink Coca Tea or Chew Coca Leaves
The coca tea (mate de coca) is the most popular tea in the Peruvian highlands. You can easily prepare a coca tea yourself! Just put some coca leaves into hot water, wait a few minutes and add some sweetener if you want.
Important note: Avoid drinking coca tea if you have to take job related drug tests. It is possible that a drug test might turn out positive, even if the leaves only contain a very small amount of cocaine.
Among locals, chewing coca leaves is very common. It’s part of their culture and they say it allows them to focus better. We have done it during several hikes, such as the Rainbow Mountain Vinicunca hike or the 5-Day Salkantay Trek to Machu Picchu and it definitely helped us.
You can also find the coca leaves in the form of cookies or sweets in every tourist shop. They are the perfect “on-the-go” snack.

Get Used to the Altitude Step by Step
Your body normally needs a couple of days to get used to the new altitude. That’s why you should take 2-3 days to get used to it. When arriving to Cusco, it’s a good idea to visit the Sacred Valley and Machu Picchu first, as they are located lower. After that you can do hiking tours, such as to the Rainbow Mountains or to the Humantay Lake.
A tour that offers all of that is our Best of Cusco in 4 Days Tour.
As a general rule of thumb for altitude sickness you should avoid climbing more than 984 – 1,640 ft. (300-500 m) a day and have a rest day every 1,968 – 2,952 ft. (600 – 900 m) you go up, or every 3-4 days.
Drink Plenty of Water
As a general rule of thumb, you can add 1.5l to your normal usage. It’s very important to keep your body hydrated.
Avoid Alcohol and Sports
It’s best to avoid alcohol, smoking and any kind of exhausting physical exercise until getting used to the altitude after a couple of days.
Eat Low-Fat Dishes and Avoid Fatty Meals
Soups, rice, pasta, potatoes, bread, fruit and chicken are great low-fat dishes and give your body the energy it needs. A good way to prevent altitude sickness is a high-carb diet, as that have shown to increase the mood, but make sure to mix it up and also to include some lean protein, such as chicken, and some healthy fats, such as avocado or nuts.
Carbohydrates are good because they require less oxygen for your metabolism than fat and protein.
Try to avoid eating anything creamy or salty because your body will need more time to digest this kind of food. Salty meals, for example, will cause a faster dehydration of your body.
Important note: Many travellers have a lack of appetite after arriving due to the altitude. As a result, they consume up to 40% less calories than usual. That’s why it’s important that you eat enough food when arriving to your destination, even if you don’t feel hungry.
Get Agua de Florida
Agua de Florida is a small bottle of yellow cologne made of different herbs. Inhaling it is supposed to help when having difficulties with the altitude, headaches and breathing problems.
It’s a famous medicine among locals. You can find it in pharmacies, small shops and in markets.
Oxishot is a small dischargeable that contains up to 8 l of oxygen. It will help you reduce headaches, fatigue and also when you have breathing problems. You can buy it in pharmacies or small shops in Cusco for around S/ 45 (around $14).
The tour of the Sacred Valley will help you with getting used to the altitude, as most sites are 1,312 – 1,640 ft. (400 – 500 m) lower than Cusco.
