Guangzhou Worlda Tips: Heat Stroke

The typhoon Nida just cracked a big joke with the people in Guangzhou.

But any way one of the two pieces of good news is that they brought us a happy day off. The other one is we enjoyed a cool week.

However after that, heat wave is attack again.

So now we have to face a big trouble, Heat Stroke.

Heat stroke is the most serious form of heat injury and is considered a medical emergency. If you suspect that someone has heat stroke -- also known as sunstroke -- call 120 (NOT 911 in China) immediately and give first aid until paramedics arrive.

Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes.

Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps, heat syncope (fainting), and heat exhaustion. But it can strike even if you have no previous signs of heat injury.

Heat stroke results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system. The medical definition of heatstroke is a core body temperature greater than 105 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, confusion, disorientation, and sometimes loss of consciousness or coma.
