The purpose of current task was to understand the relation between body temperature and watching horror movies. Total 125 subjects shared in this research work. Our body performances like a small furnace. It produces heat all the time. This heat accumulates from all day activities. When there is more or low heat out than usual, it clues to a problem. Everyone has dissimilar body temperature from normal range. The average body temperature is 98.6-degree Fahrenheit. But it can alter from the normal figure. It changes from 97 (36.1°C) to 99 0F (37.2°C) for adults and in case of babies and children, it persists higher between 97.9 and 100.4. It does not rest same all the day and throughout life. It is always fluctuating. It diverges due to your activities, age, gender, day time and food you eat. A body temperature higher from 100.4 is signified as fever. This condition is named as pyrexia. When temperature drops very low, it is hypothermia. Both states are fatal. The numbers of horror movies are accessible today. The science discovers that it activates body's fight or flight response when we follow some danger even it is not real at the moment. Our body's fight or flight machinery is regulated by hormones. The cortisol hormone is out when there is stress and it activates brain through adrenaline secretion. We realize some changes in our internal and external mechanism. The blood flow increases towards muscle and reduces towards chest and palm. So, we perceive cold around chest and palm because of sweating and dropping down of body's temperature. It was determined that here is non-significant linkage between normal body temperature and watching horror movies.
