Gases in Earth's atmosphere absorb about 90 percent of this heat and radiate it back to the surface, which is warmed to a life-supporting average of 59 F (15 C). This very helpful process is called the greenhouse effect.
Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure; this includes a high fever, low blood sugar, alcohol or drug withdrawal, or a brain concussion. Under these circumstances, anyone can have one or more seizures.
While the exact cause of some seizures can be hard to pinpoint, many seizures can be classified as either provoked or unprovoked. A provoked seizure would include traumatic injuries to the head, whereas an unprovoked seizure would include seizures caused by, for example, a congenital defect.
