Altitude Dream

Does being in good shape help against altitude sickness?

How good a person's fitness should be depends on the physical strain of the journey: the duration of the journey as a whole, the number of hours active during the days, the amount of rest days, the amount and weight of the pack, the environment and the type of activity. It is important to have all this clearly in order to be able to train in a targeted way and to ... read more

How can altitude sickness be prevented?

You should limit the speed at which you ascend by taking as much time as possible for acclimatisation. From experience we know that between 2500 and about 4000 metres is a safe ascent rate for almost everyone of about 300 metres per day. The speed of ascent is the difference in sleeping height between two stages of the day. As it takes 4-12 hours on average for altitude sickness to set in, the ... read more

What is high cerebral edema?

Altitude cerebral oedema (HACE) is also a disease that can occur at altitude. It is more commonly seen from 3700 m, but can already occur from 2600 m. This disease also involves fluid accumulation. This is not in the lungs, but in the brain: the control centre of our body and therefore crucial for our survival. The fluid accumulation causes the brain to swell and ... read more

What is pulmonary oedema?

Altitude pulmonary oedema is another illness that can occur at altitudes as low as 2500 m. The term oedema refers to an accumulation of fluid. As the name suggests, this accumulation occurs in the lungs, more specifically in the alveoli. Gas exchange takes place in these alveoli. The oxygen from the inhaled air is absorbed into the alveoli, and this is exchanged ... read more

Recognising altitude sickness and how to act

AMS is diagnosed according to the following three criteria: High rate of increase in the last 4 days Presence of headache and the presence of at least one other symptom (loss of appetite, nausea, dizziness or fatigue); A total score of 3 or more on the Lake-Louise questionnaire A total score of 3 or more on the Lake-Louise questionnaire read more

What is the cause of altitude sickness?

As we climb to higher altitudes, much changes in the environment. Apart from the fact that the air is less polluted and the trees make way for rocks and snow, the composition of the air also changes. One of these changes is that the oxygen partial pressure is getting lower. This means that there are fewer oxygen molecules in the same volume of air than there are at a lower altitude. read more

Altitude training for runners

Altitude training is a part of almost all elite training programmes for runners. More than 95% of the medalists at the World Championships and the Olympic Games have lived or trained at altitude. This simulated altitude takes place over a period of weeks or months. Studies say it takes 21 to 28 days for the body to adapt. The ... read more
