Relation of normal body temperature with cheek dimples

Body temperature is defined as the ability of our body to generate heat. Our body maintains its temperature within a moderate range even the outer temperature of environment is change. Like when we are feeling too hot, our body starts sweating to maintain its temperature within optimum range and the evaporation of sweat cools our body.5 When we feel too cold, the surface area of our blood vessels reduced to save heat by decreasing blood flow. We start shivering and by trembling of muscles our body generate more heat. Normal temperature of human body is 98.6°F or 37°C. It is an average body temperature and it may be above or below 1°F or 0.6°C depending upon the activity of body. Thermometer is a device used to measure body temperature either in Fahrenheit (°F) or degree Celsius (°C). We can measure body temperature from different parts of our body like armpit, mouth, the ear and the forehead.6 To take temperature reading from rectum is the most accurate way of measuring body temperature. If body temperature is less than the normal body temperature, this condition is said to be hypothermia. There are different reasons of hypothermia like being out in cold or excessive use of alcohol and some disorders like low thyroid. If body temperature is more than normal body temperature, this condition is known as fever or heatstroke. When heatstroke occurs human body fails to control its temperature within normal range and the temperature of the body keep rising. Heatstroke is deadly even it cause dehydration and the organs of body stop working. We need special medical treatment whenever we face this conditions.7–9
