The best way to avoid AMS is to follow these five simple steps:
1 – Go slowly. Trekking up to 5600m should be done at a snail’s pace. Be first out on the trail in the morning and last into the teahouses in the afternoon, take your time, keep your pulse and breathing rate down, enjoy the views and take plenty of breaks to take photos. Going slowly means that your body can focus on acclimatising rather than keeping you moving at a fast pace.
2 – Stay hydrated. Make sure you drink plenty of water whilst on the trail. Being hydrated helps with the acclimatisation process. As a guide, you should need the toilet more than normal and your urine should be clear.
3 – Eat. Trekking to Everest Base Camp requires lots of energy and so does the acclimatisation process. Eat well at each meal.
4 – Keep Warm. If you start to get cold your body will need to use extra resources to keep you warm. This slows down the acclimatisation process so make sure you put that fleece on when you stop and that you take a 4-season sleeping bag to stay warm at night.
5 – Get good rest. Sleep and rest are extremely important and also part of the acclimatisation process. Don’t be up chatting all night, get an early night and make sure you are warm and comfortable so that you can get a good night’s sleep.
