 [ Symptoms ] is a 96 9 degree temperature normal [ Disease ] the answer is probably if you are an adult body temperature readings can vary depending on how you take your temperature for example in an adult with no symptoms of illness a 96 9 armpit reading would not be considered abnormal at all even a 96 9 oral reading in an adult probably would not be any cause for concern a 96 9 rectal reading in an adult might be a bit unusual if you have symptoms of illness or have been exposed to frigid temperatures then that is a whole other story while most people run a fever when they become ill certain conditions and situations can cause a drop in core body temperature mild hypothermia is defined as a core body temperature below 95f if you are concerned about low body temperature especially if you are experiencing other symptoms i would suggest you make an appointment with your primary care provider this information only applies to healthy adults temperature issues are different for infants children and the elderly    all of whom may be more susceptible to hypothermia hope this helps
