Greetings from Tibet! Yesterday morning we departed Kathmandu and drove to the
Tibetan border town of Zhangmu at 2500m. After going through immigration we
had lunch and then continued to the town of Nyalam at 3750m, where we spent
the night. Today we are resting and acclimatising in Nyalam. Most members went
for a walk in the surrounding hills to an altitude of around 4400m to assist
our acclimatisation. From these hills we had excellent views of Shishapangma,
the worlds 14th highest mountain. We will stay in Nyalam again tonight and
tomorrow we will continue to the village of Tingri at around 4300m. All
members are doing well and the weather has been perfect. Lets hope it
those readers unfamiliar with what 'acclimatisation' means, it basically means
that as the human body goes to higher elevations, where each breath contains
fewer oxygen molecules, the human body recognizes that it is not getting
enough oxygen to supply the brain and other body parts. Being a very smart
machine, the human body subconciously begins to produce more oxygen carrying
red blood cells to compensate for this deficiency. As oxygen levels return to
'normal' due to this production of red blood cells and hence oxygen carrying
capacity, the body is said to have 'acclimatised'. The ability to acclimatise
varies with different people. For most people the acclimatisation process
continues to around 7000m above which, except in exceptional athletes, the
human body is unable to produce enough red blood cells to allow normal body
oxygenation. This of course affects climbing performance. Hence many climbers
choose to use supplemental oxygen when climbing above this altitude.
