The normal body temperature of a healthy human should be 98.6 degrees Fahrenheit or 37.0 degrees Celsius. Your body temperature is low when you have a slow metabolic rate. When your metabolic rate is fast your body temperature is higher. Usually temperature is lower in the morning between 4 and 6 am since your body is at rest but throughout the day as you exercise and intake food your body temperature rises. The highest temperature is between 6 and 8 pm. If your body temperature is above or below normal you might have a serious medical condition. Obviously, body temperature changes according to your geographic location. For instance, if you live in a tropical country chances are your body temperature will increase as your calorie metabolism increases. Women generally have higher body temperature than men. Since women conserve body heat more than men then they tend to feel the cold more as well. Women also have more trouble maintaining normal blood flow which will lead to cold hands and feet. Also, the more tired you are the colder you will feel. A research has found that women need to get hotter than men in order to sweat. The research also shows that women have less body fluids therefore they sweat less in order to adapt to the hot environment. Both women and men can acclimate better to heat if they exercise regularly.
