Brain-Computer Similarities, 5

Both the brain and the computer work best when they are cool. Overheating of either one can result in malfunction. Laptops can overheat when there is insufficient airflow inside the computer case. This might occur because dust builds up and block the fan openings, or some of the internal components are over working (generating more heat than usual). Your brain may overheat if you are in a situation of high heat and high humidity. This can result in a heat stroke, so called. Your brain can overheat if your temperature reaches 104 to 106 degrees, often from a virus. Very high body temperatures can lead to brain damage. If you are out in high humidity and high heat for a prolonged period you can get heat stroke. Or if you exercise excessively, especially in combination with dehydration. Signs of overheating of the brain may include headache, dizziness, fainting, confusion, nausea, hallucinations, faintness, and even coma. More tomorrow.
