Must stay warm
According to Unmerir Mirza, anyone who is trapped in the cave should be careful in the beginning so that he can stay warm.
The clothes will be kept dry. If the temperature decreases abnormally in hypothermia or body, the worst danger in the cave, then it becomes difficult for anyone to survive. '
Water
'Keeping the body warm is as important as it is necessary to keep the body's body level or water supply properly.
Drink water, but beware of dirty water. Because the stomach may be bad and vomiting for polluted water. This will make the body more dehydrated. '
However, some experts have different differences in this regard. According to them, most of the cave's water is drinkable.
However, the water that is not dirty or pure water may not harm immediately. Due to the fact that the water supply to the body should be eaten even if it is dirty.
The wind
Oxygen is very important. But the fear that people are afraid of, it's not all right, experts say. Because most of the caves have natural means of ventilation.
Even in the places where people can not move or enter, there are exactly air-going places in those places. However, carbon dioxide may increase if more people are trapped in smaller places.

Emotional pain
You may have warmth arrangements, there is no shortage of water and air, but it is difficult for anyone to keep long head cool in the dark.
