Children are most vulnerable to experience it because it is often left behind and locked in the car, for example due to overslept. In Australia, at least 1500 children trapped in a car that is overheating during the period November to December 2011.
"If the outside temperature is 29 degrees centigrade, the cabin temperature could rise to 44 degrees Celsius in 10 minutes and to 60 degrees centigrade in the next 10 minutes and it's very deadly," said Prof Peter O'Meara from La Trobe University, as quoted from Indiavision, Thursday (01/05/2012).
Brain damage caused by the heat left in the car according to Prof. O'Meara could cause loss of consciousness. If do not get immediate help, the victim could even die immediately, especially if the damage is very serious.
According to him, children are more susceptible to brain damage when overheated because of that age are much easier to lose body fluids or dehydrated. Body tissues including the brain very easily damaged when the liquid level is reduced.
"Children and pets can die or suffer serious brain damage if left in a hot car even if only in a very short time. The damage that sometimes can not really restored," said O'Meara prof.
To prevent this, Prof. O'Meara advised not to leave small children in the car. Or you can also always lock car doors when parked so that children can not enter and then trapped in the car.
The temperature inside a parked car in the sun is generally very high because of heat trapped by the glass film. The brain can experience serious damage in just 20 minutes, if someone was locked in an overheated car.
