1. Understanding Altitude Sickness

What is Altitude Sickness?

Altitude sickness occurs when you can’t get enough oxygen from the air at high altitudes. This can lead to symptoms like dizziness and headaches. It’s common in the Southern Alps, especially for new beginners.

Why Does It Happen?

As you climb higher, air pressure decreases. This means there’s less oxygen available. Your body tries to adjust, but sometimes it struggles, leading to altitude sickness.

Who’s at Risk?

Anyone can experience altitude sickness. However, factors like rate of ascent, altitude attained, and personal susceptibility play a role.

2. Symptoms of Altitude Sickness

Mild Symptoms

Initial signs can include headache, fatigue, and dizziness. If you notice these, it’s a signal to take things slow.

Moderate to Severe Symptoms

Shortness of breath, difficulty walking, and chest pain are more serious signs. If you experience these, descend immediately.

When to Seek Medical Attention

If symptoms persist or worsen after descending, seek medical help. Altitude sickness can lead to complications if not addressed.

3. Acclimatization is Key

What is Acclimatization?

Your body can adjust to the altitude over time. This natural process is called acclimatization, and it’s crucial to prevent altitude sickness.

How to Acclimatize?

Gradually increase your altitude over several days. Spend 2-3 days at an intermediate elevation before heading higher.

Benefits of Taking It Slow

By giving your body time, you reduce the risk of altitude sickness and enjoy the journey more!

4. Staying Hydrated

Drink Plenty of Water

Drinking water helps with altitude sickness. It aids in keeping your body hydrated and functioning efficiently.

Avoid Alcohol and Caffeine

Both can lead to dehydration. In the Southern Alps, it’s best to save the celebrations for lower altitudes!

Signs of Dehydration

Watch for dark urine, dry skin, and thirst. These might indicate you’re not drinking enough.

5. Proper Diet Matters

Eat Carbohydrates

Carbs provide energy which can be crucial in high altitudes. Opt for whole grains, fruits, and vegetables.

Avoid Heavy, Fatty Foods

These can make you feel sluggish. In the challenging terrains of the Southern Alps, you want to be at your best!

Regular Small Meals

Eating smaller meals more frequently can help maintain energy and prevent nausea from altitude sickness.

6. Over-the-Counter Medications

Ibuprofen and Aspirin

These can help alleviate mild symptoms of altitude sickness like headaches.

Prescription Medications

For those at high risk, doctors might prescribe medications like Acetazolamide. Always consult a physician first!

Always Carry a First-Aid Kit

It’s a good idea to have basic medications on hand, especially in remote areas of the Southern Alps.

7. Physical Conditioning

Stay Fit

Being physically fit doesn’t make you immune to altitude sickness, but it does help your body cope better.

Pre-Trip Training

Prepare for your trip with regular cardio exercises like running, swimming, or cycling.

Listen to Your Body

Pushing too hard can increase the risk of altitude sickness. It’s okay to rest when you need to!

8. Sleep at Lower Altitudes

Daytime Exploration

It’s okay to climb and explore during the day. But when it’s time to rest, go to a lower altitude.

Benefits of Descending

Sleeping at lower altitudes gives your body a break and reduces the risk of altitude sickness.

Remember: “Climb High, Sleep Low”

This mountaineer’s adage is a golden rule for preventing altitude sickness in places like the Southern Alps.

9. Educate Yourself

Attend Altitude Awareness Workshops

Some local organizations in New Zealand offer courses on understanding and preventing altitude sickness.

Join Group Tours

For new beginners, group tours can provide guidance, experience, and shared knowledge on managing altitude sickness.

Stay Informed

Always keep updated with weather and altitude conditions in the Southern Alps.

10. Know When to Turn Back

Recognize Limitations

There’s no shame in turning back if you feel unwell. The mountains will always be there!

Safety First

Remember, the goal is to enjoy the beauty of the Southern Alps safely. Don’t push yourself too hard.

Trust Your Instincts

If something feels off, trust your gut. It’s better to be safe than sorry, especially with altitude sickness on the line.


Exploring the Southern Alps of New Zealand is a dream for many. But to truly enjoy the experience, understanding and preventing altitude sickness is essential. By acclimatizing properly, staying hydrated, eating right, and listening to your body, you can relish the beauty of the mountains without the hindrance of altitude sickness.
