Freeze the pain of chilblains

Watch out for the blisters arising at high altitudes
|
Ladakhis say that if somebody reaches you all the way there it has to be a thickest friend or the fiercest enemy.
The Indian Army is on its toes at the world's highest battlefield, Siachen, so that the nation has its peaceful days and nights.
The commonest problem arising at that altitude is a small blister on the hands or feet which could form an ulcer and if the complexity continues, could lead to amputation too.
It is blood circulation that maintains our body temperature.
The increased sensitivity of the nervous system due to low temperatures causes constriction of the blood vessels and thereby the tissues of hands and feet are not replenished with oxygen thereby resulting in decreased sensation and function.
Even a minor injury to feet or internally to the blood vessels can initiate rapid clotting that can travel anywhere along the vessels to cause strokes.
The fluid between body tissues and cellular spaces also freezes and crystallise leading to reduced oxygen supply to the injured areas.
As the numbness ensues in fingers and toes, it is difficult to feel the amount of heat of water that could lead to scalds and blisters again.
To say the least even a blister is not a good development as it can lead all the way to necrosis. In addition, the repeated warming and freezing of an injured part can accentuate necrosis.
