Altitude sickness, also known as acute mountain sickness (AMS), is a common concern for people undertaking expeditions above 4,000 metres (13,123 feet). Altitude Sickness occurs when the body struggles to adapt to decreased oxygen levels at high altitudes, leading to symptoms ranging from mild headaches and fatigue to severe complications. Fortunately, there are effective strategies to prevent altitude sickness, including pre-acclimatisation using the Boxd altitude hypoxic chamber.
Understanding Altitude Sickness
Altitude sickness typically affects individuals at elevations above 2,500 metres (8,200 feet) and can impact anyone, regardless of fitness level. As the body reacts to reduced oxygen availability, symptoms can include:
Effective Strategies to Prevent Altitude Sickness
1. Gradual Ascent
One of the most effective ways to prevent altitude sickness is to ascend gradually. Aim to increase your elevation by no more than 300 to 500 metres (1,000 to 1,600 feet) per day once you reach elevations above 2,500 metres (8,200 feet). This gradual approach allows your body ample time to acclimatise to the changing oxygen levels.
• Spend Extra Days at Intermediate Elevations: If you’re planning a significant ascent, consider spending an additional day or two at intermediate altitudes. This extra time can enhance acclimatisation and reduce the risk of AMS.
2. Stay Hydrated
Dehydration can worsen altitude sickness symptoms, so it’s essential to stay well-hydrated. Drink plenty of water, aiming for at least 3-4 litres per day, especially when at higher altitudes. Consider the following:
• Electrolyte Solutions: Adding electrolyte tablets or powders to your water can help maintain electrolyte balance, further aiding hydration.
3. Balanced Diet
A well-balanced diet is vital for maintaining energy and combating altitude sickness. Focus on the following:
• Carbohydrate-Rich Foods: Consuming complex carbohydrates can help maintain energy levels. Foods such as whole grains, fruits, and vegetables are excellent choices.
• Avoid Heavy Meals: High-fat and heavy meals can hinder digestion and contribute to nausea. Opt for lighter meals that are easier on the stomach.
4. Medications
Some individuals may find it beneficial to use medications to aid in acclimatisation:
• Acetazolamide (Diamox): This medication can help speed up the acclimatisation process and is often recommended for those prone to altitude sickness. It’s essential to consult a healthcare professional before starting any medication.
• Ibuprofen or Aspirin: These over-the-counter pain relievers can help alleviate mild headaches associated with altitude sickness.
5. Rest and Recovery
Rest is a critical factor when acclimatising to high altitudes. Ensure you prioritise the following:
• Listen to Your Body: Pay attention to how you feel. If you experience symptoms of altitude sickness, take time to rest and avoid strenuous activities until you feel better.
• Sleep Quality: Try to maintain good sleep hygiene. Sleep disturbances are common at altitude, so consider using techniques such as earplugs and eye masks to improve rest.
6. Avoid Alcohol and Smoking
Both alcohol and smoking can exacerbate dehydration and hinder your body’s ability to acclimatise. Avoid these substances before and during your time at high altitude to minimise the risk of altitude sickness.
Why Pre-Acclimatisation is Crucial
To mitigate the risk of altitude sickness, it is essential to prepare your body for the challenges of high altitude. Pre-acclimatisation allows your body to adjust to lower oxygen levels before you ascend, significantly enhancing performance and safety while reducing the likelihood of AMS.
Using the Boxd Altitude Hypoxic Chamber
The Boxd altitude hypoxic chamber provides a cutting-edge solution for pre-acclimatisation. This chamber simulates high-altitude conditions, enabling users to train in lower oxygen environments without leaving their home or gym. Here are some key benefits of using the Boxd chamber:
1. Controlled Environment: The Boxd hypoxic chamber offers a safe and controlled space for acclimatisation, reducing the risks associated with high-altitude travel.
2. Customisable Heights: Boxd Altitude can adjust oxygen levels to replicate specific altitudes, tailoring training sessions to your upcoming expeditions.
3. Increased Lactate Threshold: Regular sessions in the hypoxic chamber can improve lactate threshold, enabling alpinists to perform at higher intensities for longer periods.
4. Improved Recovery: Training in hypoxic conditions can accelerate recovery, allowing for more effective training sessions.
5. Enhanced VO2 Max: Exposure to lower oxygen levels can lead to improved VO2 max, crucial for endurance during demanding high-altitude activities.
How to Incorporate Boxd Altitude Training
To effectively utilise the Boxd altitude hypoxic chamber, consider the following steps:
• Start Early: Begin your sessions at least a few weeks before your planned high-altitude expedition to give your body adequate time to acclimatise.
• Gradual Increase: You will start at lower altitudes and progressively increase the intensity and duration of your sessions, mimicking natural acclimatisation.
• Stay Hydrated: Ensure you are well-hydrated before, during, and after your hypoxic training sessions, as dehydration can exacerbate altitude sickness symptoms.
• Monitor Your Body: Pay close attention to your body’s responses during training, while using the most accurate and precise Pulse Oximeter to measure the body’s blood oxygen saturation and pulse, making sure it’s a safe level.

Conclusion
Preventing altitude sickness is essential for anyone planning to undertake high-altitude expeditions. By incorporating pre-acclimatisation strategies, with the Boxd altitude hypoxic chamber, you can significantly reduce your risk of AMS. Alongside gradual ascent, proper hydration, and dietary considerations, you can effectively prepare your body for the challenges of altitude.
If you’re looking to enhance your training and tackle your next alpine adventure with confidence, consider using Boxd Altitude hypoxic chamber into your routine. Together, we can help you conquer the heights without the fear of altitude sickness.
