What Is Altitude Sickness?

Altitude sickness, also known as acute mountain sickness (AMS), occurs when the body struggles to adapt to lower oxygen levels at high elevations.

At high altitude, the air contains less oxygen, making it harder for the body to function normally until it acclimates.

Altitude sickness can affect travelers of any age or fitness level.

Why Does Puno Cause Altitude Sickness?

Puno’s high elevation is the main reason travelers experience altitude-related symptoms.

Many visitors arrive directly from lower-altitude cities such as Lima, causing the body to react quickly to the sudden change in oxygen levels.

The combination of:

• High altitude
• Dry air
• Cold temperatures
• Physical activity

can make symptoms stronger during the first days of the trip.

Common Symptoms of Altitude Sickness

Symptoms usually appear within the first few hours after arriving in Puno.

• Headaches
• Dizziness
• Fatigue
• Nausea
• Shortness of breath
• Difficulty sleeping
• Loss of appetite

For most travelers, symptoms are mild and improve after proper acclimatization.

How to Prevent Altitude Sickness in Puno

Acclimatize Slowly

Allow your body time to adapt before engaging in strenuous activities.

Many travelers spend time in Cusco before continuing on to Puno, which can help with acclimatization.

Drink Plenty of Water

Staying hydrated is extremely important at high altitude.

The dry Andean air can quickly lead to dehydration, which may worsen symptoms.

Avoid Alcohol on the First Day

Alcohol can intensify dehydration and make altitude symptoms worse.

It is best to avoid alcohol during the first 24 to 48 hours.

Eat Light Meals

High-carbohydrate meals such as quinoa, potatoes, rice, and soups are easier to digest at altitude.

Rest During Your First Day

Take it easy after arriving in Puno.

Avoid intense hikes or excessive physical activity until your body adjusts.

Does Coca Tea Help?

Coca tea is one of the most traditional remedies used in the Andes for altitude sickness.

Many hotels and local restaurants in Puno offer coca tea to travelers.

Although scientific evidence is limited, many visitors report feeling relief after drinking it.

Should You Take Altitude Medication?

Some travelers use medications such as acetazolamide to help prevent altitude sickness.

It is important to consult a healthcare professional before taking any medication.

Travelers with medical conditions should seek professional medical advice before visiting high-altitude destinations.

When Symptoms Become Serious

In rare cases, altitude sickness can become severe.

Seek medical attention immediately if you experience:

• Difficulty breathing
• Chest pain
• Confusion
• Loss of coordination
• Severe headaches that do not improve

These symptoms may indicate serious altitude-related conditions that require immediate treatment.

How Long Does Acclimatization Take?

Most travelers begin feeling better after 24 to 48 hours.

The body gradually adapts to lower oxygen levels, allowing travelers to enjoy activities more comfortably.

Everyone reacts differently to altitude, so some visitors may acclimatize faster than others.
