Prepare yourself for altitude changes and stay safe while hiking.
Don’t let altitude sickness ruin your hiking adventure! Whether you’re tackling high mountain trails or just exploring higher elevations, altitude sickness can sneak up quickly. Fortunately, with the right precautions, you can prevent or manage its symptoms.
Here are eight effective ways to prevent and treat altitude sickness while hiking, so you can enjoy the great outdoors without discomfort.
1. Acclimate Slowly to High Altitudes
Give your body time to adjust to higher altitudes by ascending gradually. Spend a day or two at a moderate elevation before tackling higher trails to allow your body to acclimatize. If possible, climb slowly, increasing your elevation by no more than 1,000 feet per day. This will reduce your risk of altitude sickness and allow your body to get used to the thinner air. Staying hydrated and resting during this period is also important for acclimation.
2. Stay Hydrated to Combat Dehydration
At higher altitudes, your body loses fluids more quickly, increasing the risk of dehydration, which can worsen altitude sickness. Drink plenty of water throughout your hike, even if you don’t feel thirsty. Avoid alcohol and caffeine, as they can dehydrate you. Adding electrolyte tablets to your water can help maintain a proper balance of salts in your body, keeping you hydrated and less prone to altitude sickness symptoms like headaches and fatigue.
3. Eat Light, Nutritious Food for Energy
Eating smaller, more frequent meals that are rich in carbohydrates can help your body adjust to high altitudes. Carbs are easier to digest and provide your body with the energy it needs to function in thinner air. Avoid heavy, fatty foods that can slow digestion and make you feel sluggish. Instead, opt for high-energy snacks like fruits, nuts, and whole grains to fuel your hike and help prevent nausea or dizziness associated with altitude sickness.
4. Pace Yourself and Avoid Overexertion
Hiking at high altitudes requires more effort, so it’s crucial to pace yourself and avoid pushing too hard. Overexertion can worsen altitude sickness symptoms such as headaches and shortness of breath. Take frequent breaks, especially when climbing steep sections, and listen to your body. If you feel fatigued or dizzy, slow down or stop to rest. By hiking at a steady pace and gradually increasing your altitude, you’ll reduce your risk of experiencing altitude sickness.
5. Consider Using Acclimatization Medications
If you’re hiking to very high altitudes, consider using medications like acetazolamide (Diamox) to help your body acclimatize more quickly. These medications can reduce symptoms of altitude sickness by increasing your breathing rate, which helps you get more oxygen. Consult with your doctor before your hike to see if medication is appropriate for you, especially if you’re prone to altitude sickness or planning a trek above 8,000 feet. Take these medications as directed for the best results.
6. Use Breathing Techniques to Increase Oxygen Intake
Practicing deep, controlled breathing can help you maximize oxygen intake and reduce symptoms of altitude sickness. Focus on taking slow, deep breaths in through your nose and out through your mouth, expanding your diaphragm with each breath. This technique can help you get more oxygen to your muscles and brain, making it easier to hike at high elevations. Breathing exercises are especially helpful during steep ascents, when oxygen levels drop and symptoms might start to develop.
7. Descend If Symptoms Worsen
If you start to experience severe altitude sickness symptoms like intense headaches, nausea, or confusion, descend to a lower altitude immediately. Even a descent of a few hundred feet can significantly reduce symptoms and allow your body to recover. Don’t ignore worsening symptoms, as altitude sickness can become dangerous if untreated. Rest at a lower elevation until you feel better, and consider abandoning the hike if symptoms persist.
8. Rest and Sleep at Lower Elevations
Sleeping at a lower elevation than where you’ve hiked during the day allows your body to recover and acclimatize more effectively. If possible, plan your hike so that you gain altitude during the day but descend to lower campsites for the night. This helps reduce the strain on your body while still allowing you to explore high-altitude areas. Resting at a lower elevation also improves sleep quality, which is crucial for your body’s recovery and adaptation
