Sherpa’s Working on Mount Everest
If you ask anyone what does a ‘Sherpa’ do in the Himalayas most will probably say that it is a local person who is employed by an expedition company to carry their bags and equipment up and down high mountains such as Mount Everest.
Frostbite at High Altitude
Frostbite is an injury which happens in extreme cold conditions i.e. at a temperature of zero degrees Celsius or below. In medical terms frostbite is known as congelatio. The injury happens because of the freezing of the tissues of the affected parts. The most affected parts are fingers, chin, toes, nose, cheeks and earlobes. The skin tissues and the blood vessels in the extreme cold conditions get damaged and this is what results in a frostbite.
