The intention of present study was to evaluate any relation between nitrite in urine and watching horror movies. Over-all 100 subjects participated in this project. Nitrates and nitrites are the nitrogen comprising compounds. The variance is only in their structures. They are existing naturally in some vegetables, for example, green vegetable, celery and cabbage. The urine containing nitrates is considered as normal but existence of nitrites leads to urinary tract infection (UTI). Injurious bacteria live in kidneys, ureters, bladder and urethra. They induce nitrates into nitrites by the support of their enzymes. These are the cause of nitrites in urine that is perilous medical condition. The symptoms usually confronted during this problem are cloudy urine, smelling urine, blood in the urine, burning urination and increased urgency of urination. As we consider horror movies, the first thing that derives to mind is horror, fear or terror. Such movies even can congeal your blood. The impact of horror movies depends upon the person. Some people take pleasure watching these movies and some feel uncomfortable. But mostly people are ignorant about the effects of such scary movies. Some theories depict the positive impacts of such films and some make known their negative prospects. It was determined from the present study that watching horror movies had not really influenced people for having nitrites in their urine. A very few exhibited the positive results of nitrites in the urine which exposed non-significant relation between urine nitrites and watching horror movies.
