Overheating occurs when an object or system exceeds its optimal temperature range, leading to potential damage or malfunction. This can happen in various contexts, such as electronics, engines, or even the human body. For example, when a computer runs too many applications simultaneously, it may overheat, causing performance issues or hardware failure. In the human body, overheating can result from excessive physical activity, high temperatures, or dehydration. Symptoms may include excessive sweating, dizziness, or heat exhaustion. It is essential to recognize these signs and take action, such as drinking water or moving to a cooler environment, to prevent serious health risks.
