Question: A very common belief is that eating ice- creams and ice golas (photo on the left) during summer gives a cooling effect to the body. This is not scientifically true. Do you know why?
Answer: Human being is a warm blooded animal. The natural thermostat, hypothalamus present in the human brain, maintains the body temperature at 370 Celsius (98.6 Fahrenheit). Due to summer heat, even if the body temperature rises above its normal level, ice or ice creams do not have the capacity to absorb the extra heat. For example: an ice cube of 2.5 x 2.5 x 2.5 centimetres dissolves in the mouth, it absorbs heat equivalent to only 1.3 calorie. Thus the fall in temperature is nearly 0.004° Celsius for an average human being weighing 68 kilograms.
