Travelling is an exciting adventure, whether you’re heading off on a once-in-a-lifetime trek to the Andes or simply taking a long-haul flight to your dream destination. But did you know that your body can react to changes in altitude and prolonged periods of sitting in unexpected ways? From jet lag and dehydration to the risks of altitude sickness, there are several factors to consider when preparing for your trip.

At Eltham Pharmacy Travel Clinic, we provide expert travel health advice and altitude sickness medication to ensure you stay well while travelling. Whether you’re planning to scale Kilimanjaro, explore the Himalayas, or visit the high-altitude city of La Paz, it’s important to be prepared.

Did You Know? High Altitude Can Cause Altitude Sickness

Altitude sickness, also known as acute mountain sickness (AMS), occurs when your body struggles to adjust to lower oxygen levels at higher elevations. It can affect anyone travelling above 2,500 metres (8,200 feet), with symptoms becoming more severe the higher you go.

Destinations where altitude sickness is common include:

• – Cusco and Machu Picchu, Peru (3,400m)
• – La Paz, Bolivia (3,640m)
• – Everest Base Camp, Nepal (5,364m)
• – Kilimanjaro, Tanzania (5,895m)
• – Rocky Mountains, Colorado, USA (3,000m+)

Symptoms of altitude sickness can develop within hours of arrival at high altitude and include:

• – Headaches
• – Nausea and dizziness
• – Shortness of breath
• – Fatigue and weakness
• – Difficulty sleeping

Did You Know? Altitude Sickness Medication Can Help

While gradual acclimatisation is the best way to prevent altitude sickness, altitude sickness medication such as acetazolamide (Diamox) can help your body adjust more quickly. This medication works by stimulating breathing, allowing you to take in more oxygen, and reducing fluid build-up in the lungs and brain.

At Eltham Pharmacy, we offer travel health consultations where we can advise whether altitude sickness medication is suitable for you, provide the correct dosage, and offer tips on how to use it effectively.

Did You Know? Hydration Is Key to Staying Healthy When Flying

Long-haul flights and high-altitude environments can both lead to dehydration, which can make altitude sickness symptoms worse. Airplane cabins have low humidity levels, which can dry out your skin, eyes, and throat, leading to discomfort.

To stay hydrated while flying and at high altitude:

• – Drink plenty of water before and during your journey
• – Avoid excessive caffeine and alcohol, as they contribute to dehydration
• – Use a hydrating nasal spray or saline solution to prevent dry airways
• – Consider electrolyte-replacement drinks if travelling to a very dry climate

Did You Know? Blood Circulation Slows Down on Long Flights

Sitting still for long periods during a flight can lead to poor circulation, increasing the risk of deep vein thrombosis (DVT). DVT is a condition where blood clots form in the deep veins, typically in the legs, and can become dangerous if the clot travels to the lungs.

To improve circulation on a flight:

• – Get up and move every couple of hours
• – Perform simple foot and leg exercises while seated
• – Wear compression socks to help blood flow
• – Stay hydrated to prevent thickening of the blood

At Eltham Pharmacy, we stock a range of travel essentials, including compression socks, to help reduce your risk of DVT while flying.

Did You Know? Your Diet Affects Your Energy Levels at High Altitudes

Eating well before and during your high-altitude trip can help your body cope with the reduced oxygen levels. Heavy, greasy foods can slow digestion, making altitude sickness symptoms worse, while nutrient-rich foods can help maintain energy levels.

For a healthy high-altitude diet:

• – Eat carbohydrate-rich foods like whole grains, fruits, and vegetables to provide energy
• – Avoid excessive salt, as it can contribute to dehydration
• – Include iron-rich foods such as spinach, beans, and lean meats to support oxygen transport in the blood
• – Drink ginger tea to help with nausea, a common altitude sickness symptom

Did You Know? UV Exposure Is Stronger at High Altitudes

At higher elevations, UV radiation levels are much stronger, increasing the risk of sunburn and eye damage. The thinner atmosphere provides less protection from the sun, meaning even on cloudy days, you can still get sunburnt.

To protect yourself from UV exposure:

• – Wear high-factor sunscreen (SPF 50+) and reapply regularly
• – Use UV-protective sunglasses to shield your eyes
• – Wear a wide-brimmed hat for extra protection

Eltham Pharmacy stocks a range of travel-sized sun care products to help keep you protected on your adventures.
