But despite their physiologica benefit, those neurochemical changes can affect our brain, and impair our mental functioning. During the initial stages of an emergency situation our brains may perform poorly, potentially resulting in poor decision-making and memory failures. Fortunately when the flood waters came crashing in, the Thai footballers and coach appear to have remained level headed. They were able to control feelings of panic, and made the rational decision to find a safe place and wait. (5) As the immediate danger from the flood waters receded, more long-term survival needs will have come into focus. Everyche knows that the human body has basic physical requirement: an adequate supply of food, water and warmth. What people often forget is that brain function is also sonsitive to environmental factors. When exposed to the elements, dehydrated, hungry, or suffering from sleep deprivation the human brain cannot function within its normal operating parameters. In these conditions people can make poor decisions which can put them at risk. The Thai footballers seem to have managed to keep themselves hydrated, and although they were clearly hungry when they were found, they appeared cognitivelyg intact, looking alert and asking appropriate questions Again, this shows that the boys and their coach managed to stay both physically and psychologically healthy during the nine long days they spent waiting in the dark @2 How did the boys and their coach react to the life-threatening situation? A They kept themselves alive and mentally stable. B They made poor decisions due to the chemical changes in their brains. C They became too weak to react, due to lack of food and water. D trauma they went through. They became physically and mentally weak from the
