Trekking the Annapurna Circuit: Health and Safety Tips for Altitude, Hydration, and Acclimatization

By Glorious Himalaya on February 25, 2024 in Trekking

The Annapurna Circuit Trek is one of Nepal’s most popular trekking spots. It is pretty challenging, so if you are a beginner, a few health and safety trips revolve around altitude, hydration, and acclimatization during your circuit trek.

In Nepal, the Annapurna Circuit Trek is among the highly commercial treks like Everest and the Annapurna Base Camp Trek. The trek is beautiful and takes you to the top of Thorong La Pass at 5416m. Since you will be trekking at such a height, taking care of your health and safety is essential.

The most crucial factor that can hamper your health during your high-altitude circuit trek is the high risk of altitude sickness. To be wary of altitude sickness, you must first know and understand it. You must also know its symptoms and how you can prevent them. Factors like acclimatization, hydration, and altitude are crucial for your health and safety during your trek.

So, let’s get more into it.

Health and Safety Tips for Annapurna Circuit Trek

To enjoy your Annapurna Base Camp Trek, you must be physically and mentally healthy. Follow these health and safety tips to stay healthy throughout the Trek.

Understand Altitude Sickness:

Altitude, or acute mountain sickness, is a primary concern for trekkers at high altitudes. During trekking at high altitudes, the body is not used to the weather, temperature, and, most importantly, the oxygen level. When the body doesn’t feel it is receiving the required oxygen, it becomes weak as breathing becomes difficult.

Altitude Sickness can be mild to extremely severe. There are two severe cases of sickness: high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). The light symptoms include coughing, fever, headache, and nausea; however, in HAPE and HAPE, the patient can even lose their life. Hence, it is essential to know the degree of severeness, prepare for medical help immediately, and lower the altitude as quickly as possible.


One of the best ways of preventing altitude sickness is gradual acclimatization. It is essential to take time to ascend to a high altitude and get used to it. The oxygen level is low at higher altitudes, so your body must get used to those levels for level breathing.

Hence, your trekking agency or guide advises you to include acclimatization during your trek. At least 1-2 days of acclimatization, especially during your Annapurna Circuit Trek, is always recommended. Avoid rushing to the altitude and rapid ascents at all costs.

Stay Hydrated:

Another way to prevent altitude sickness is to stay hydrated. Proper hydration is necessary to avoid dehydration, another major cause of dehydration. You must drink water throughout the day and other energy drinks, electrolyte-rich fluids, and herbal teas mixed with honey, lemon, and ginger.

So, to keep yourself hydrated, always bring a leather water bottle or buy sparkling water. Throughout your journey, you can ask for hot water in your tea houses for a specific extra charge, so do it all the time.

Eat Nutritious Meals:

It is essential to stay fit and healthy during your Annapurna Circuit Trek. The best way to do this is to eat nutritious meals throughout the trek. Meals filled with proteins and carbohydrates will give you additional energy and raise your stamina.

Throughout your trek, always keep dried fruits, energy bars, nuts, and juices with you to fuel your body with energy at any time. Also, always listen to your body when you feel hungry. It depends mostly on balanced diets and vegetable products rather than meats. This is because meats in higher altitudes are sometimes uncooked.

Be Physically Fit

Getting fit beforehand is essential if you plan to do the Annapurna Circuit trek. The trek involves walking on steep and uneven terrain, which can be challenging even for experienced trekkers. Therefore, we recommend starting a fitness routine at least two to three months before you begin the task.

If you want to increase your stamina and endurance, including cardio exercises such as running, cycling, or swimming in your fitness routine is essential. Strength training exercises such as squats, lunges, and push-ups should also be included to build muscle and prepare your body for carrying a backpack. Additionally, include stretching exercises to improve your flexibility and avoid injuries.

Listen to Local Advice:

Local guides and porters are invaluable resources for trekking in the Annapurna Circuit, as they have extensive knowledge of the terrain, weather conditions, and altitude-related risks. Listen to their advice and heed their recommendations for safe trekking practices, including pacing yourself, staying hydrated, and recognizing the signs of altitude sickness. Trust their expertise and experience, and don’t hesitate to ask questions or voice any concerns you may have about your health and safety on the trail.

Be Prepared for Weather Changes:

Weather conditions in the Annapurna region can be unpredictable, with sudden temperature, wind, and precipitation changes. Pack layers of clothing to stay warm and dry in varying weather conditions, including a waterproof jacket, insulated layers, and moisture-wicking base layers. Protect yourself from the sun’s harmful rays by wearing sunscreen, sunglasses, and a wide-brimmed hat. Be prepared for cold temperatures at higher altitudes by dressing in warm, insulating layers.

At the end:

Hence, these are essential health and safety tips for your Annapurna Circuit Trek. While the trek is mixed with fun and challenge, your health and safety always play a big part. Attention to acclimatization, altitude, weather, diet, and maintaining hydration is crucial so that you don’t fall ill and don’t miss out on one of the best experiences of your life.
