What Is Altitude Sickness?

Altitude sickness, also known as acute mountain sickness (AMS), occurs when your body struggles to adjust to lower oxygen levels at high elevations. Symptoms can range from mild discomfort to more serious conditions if left untreated.

Common symptoms include:

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

Most visitors experience only mild symptoms that improve within 24 to 48 hours.

Why Does Altitude Sickness Happen in Cusco?

Cusco’s elevation is significantly higher than many major cities around the world. At this altitude, the air contains less oxygen, forcing your body to work harder to deliver oxygen to your muscles and organs.

Travelers flying directly into Cusco may notice symptoms shortly after arrival because the body has not had enough time to acclimatize.

Best Altitude Sickness Tips in Cusco

Take It Easy on Your First Day

One of the most important altitude sickness tips in Cusco is to avoid strenuous activities immediately after arrival.

Instead of rushing to visit every attraction, spend your first day:

• Walking slowly around the city center
• Relaxing at your hotel
• Staying hydrated
• Allowing your body to adjust naturally

Saving demanding activities for later can significantly reduce discomfort.

Stay Hydrated

Dehydration can worsen altitude sickness symptoms.

Drink plenty of:

• Water
• Herbal teas
• Electrolyte drinks

Avoid excessive consumption of alcohol and caffeinated beverages during your first days, as they can contribute to dehydration.

Drink Coca Tea

Coca tea is one of the most traditional remedies used throughout the Andes. Many hotels in Cusco offer complimentary coca tea to help visitors adapt to the altitude.

Benefits may include:

• Reduced headaches
• Improved digestion
• Increased energy

While coca tea is not a medical treatment, many travelers find it helpful during acclimatization.

Eat Light Meals

Heavy meals can make your body work harder when it is already adjusting to the altitude.

Choose foods such as:

• Soups
• Fruits
• Vegetables
• Lean proteins

Traditional Peruvian soups are an excellent option during your first days in Cusco.

Get Plenty of Rest

Your body needs extra energy to adapt to higher elevations.

Try to:

• Sleep well before your trip
• Avoid overexertion
• Schedule downtime during your first day

Even healthy and physically fit travelers may feel tired initially due to the reduced oxygen levels.

Avoid Alcohol During Acclimatization

Although Cusco offers exciting nightlife and excellent restaurants, it is wise to limit alcohol consumption during the first 24 to 48 hours.

Alcohol can:

• Increase dehydration
• Intensify headaches
• Disrupt sleep quality

Waiting a couple of days before enjoying alcoholic beverages can help your body adjust more effectively.

Consider Spending Time in the Sacred Valley First

Many experienced travelers choose to stay in the Sacred Valley before spending several days in Cusco.

The Sacred Valley sits at a lower elevation than Cusco, allowing for a gentler acclimatization process.

Popular destinations include:

• Sacred Valley of the Incas
• Pisac
• Ollantaytambo

This strategy is especially useful for travelers planning hikes or multi-day adventures.

Listen to Your Body

Everyone adapts differently to altitude.

If you experience symptoms:

• Rest immediately
• Drink fluids
• Avoid strenuous activity
• Seek medical attention if symptoms worsen

Never ignore severe symptoms such as confusion, difficulty breathing at rest, or persistent vomiting.

Altitude Sickness Medication

Some travelers use medications such as Acetazolamide (Diamox) to help prevent altitude sickness.

Before taking any medication:

• Consult your doctor
• Follow prescribed instructions
• Discuss any existing health conditions

Medication may be especially useful for travelers with previous experiences of altitude sickness.

How Long Does It Take to Acclimatize in Cusco?

Most visitors begin feeling better after 24 to 48 hours. Full acclimatization may take several days depending on:

• Age
• Physical condition
• Previous altitude exposure
• Individual response

Giving yourself time to adjust is one of the best ways to enjoy your trip comfortably.

Can You Visit Machu Picchu if You Have Altitude Sickness?

Yes. Interestingly, Machu Picchu sits at a lower elevation (approximately 2,430 meters / 7,972 feet) than Cusco.

Many travelers who experience mild symptoms in Cusco feel noticeably better when visiting Machu Picchu.

However, proper acclimatization before exploring the region is still recommended.
