FutureStarrWhat is a normal temperature
You probably always heard that the average human body temperature is 98.6 F. But the reality is that a "normal" body temperature can fall within a wide range, from 97 F to 99 F. It’s usually lower in the morning and goes up during the day. It peaks in the late afternoon or evening, sometimes by as much as 1 or 2 degrees.Normal body temperature varies by person, age, activity, and time of day. The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).
A healthy body, generally, is pretty good at keeping its temperature at a comfortable level: “For example, if you go outside on a very cold day, you will notice that your skin temperature is going to go down, but your core temperature inside will stay in the normal range,” explains Dr. Ford. Normal body temperature ranges from 97.5°F to 98.9°F (36.4°C to 37.2°C). It tends to be lower in the morning and higher in the evening. Most healthcare providers consider a fever to be 100.4°F (38°C) or higher. High fevers may bring on seizures or confusion in children. It's not how high the temperature is, but how fast the temperature goes up that causes a seizure.
Most people think a normal body temperature is an oral temperature (by mouth) of 37°C (98.6°F). This is an average of normal body temperatures. Your normal temperature may actually be 0.6°C (1°F) or more above or below this. Also, your normal temperature changes by as much as 0.6°C (1°F) during the day, depending on how active you are and the time of day. Body temperature is very sensitive to hormone levels. So a woman's temperature may be higher or lower when she is ovulating or having her menstrual period. A decrease in metabolism, an abnormality in mechanical muscular function, or exposure to ambient temperatures below the normal body temperature may result in hypothermia. At a temperature of 32°C (89.6°F), oxygen consumption decreases as a function of hypometabolism, the oxygen dissociation curve shifts to the left so that less oxygen is given up to the tissues, and there is a generalized inhibition of enzyme activity.
