why does my body temperature fluctuate so much

Your body s temperature seems to fluctuate somewhat higher
or lower than the normal 98. 6 F (37 C). Or, your body
temperature is somewhat different each time you take it. Normal body temperature on average is approximately 98. 6бF. It's quite common, however, for body temperature to fluctuate 1бF one way or the other. This fluctuation can occur for a number of reasons. For example, if you're quiet and relaxed, your body temperature may drop a bit. But if you're active and racing around during the day, it may elevate to the higher end within the normal range. Other factors that affect body temperature include metabolic rate, weight, exercise, age, hormones, pregnancy, and gender. The body's biological clock also affects body temperature. For example, prior to going to sleep the body cools its body temperature somewhat to help bring on sleep. As we wake up, the biological clock increases body temperature so that we can function normally during the day. Bacterial infection can also cause the body temperature to rise.


In fact, it's one of the most common causes of increased body temperature. Since viruses and bacteria have a hard time surviving at temperatures higher than normal body temperature, when the body detects a bacterial infection, it involuntarily increases its temperature (fever) and increases blood flow to speed up the body's defense actions in order to fight the infection. It's not uncommon for the body to raise its body temperature as much as 3 to 5бF to fight off an infection. Because elevated body temperature also causes harm to the body, we don't want to let prolonged high temperatures go untreated. As we mentioned earlier, isn't uncommon, however, for body temperatures to fluctuate 1б F above or below the normal range. This is considered normal. There are other factors that can affect body temperature, including:
Medications - antibiotics, narcotics, and antihistamines (to name a few) Medical conditions - heart condition, heart attack, cancer, leukemia, and Hodgkin's lymphoma How you take your body temperature may also produce varying results.


For example, rectal or tympanic (ear) temperatures are normally as much as 1бF higher than oral temperatures. Axillary (armpit) temperature may be as much as 1бF lower than oral temperatures. Regarding stress and anxiety, since both can increase the bodyБs metabolism, and the by-product of increased metabolism is heat, being stressed and/or anxious can also increase body temperature. It's also common for episodes of increased stress and anxiety to cause a person to feel cold or chilly because of the restricted blood flow to the skin due to the constriction of blood vessels caused by the stress response. When we feel cold or chilly, the body wants to increase its body temperature because it is dropping toward the low end within the normal range. So yes, stress and anxiety can cause a change in body temperature. But that change is a minor one, and not more than plus or minus 1б F. If you are experiencing a more dramatic change, you should see your doctor.


There may be another reason for your higher or lower body temperature. Addressing your stress and anxiety issues can help to diminish and eventually eliminate body temperature change due to stress and anxiety. Also, regular deep relaxation and regular mild exercise can also help to stabilize fluctuating body temperatures. Nevertheless, anxiety-caused changes in body temperature arenБt harmful, so thereБs no need to worry about a change in body temperature. These changes will subside as you address your stress and anxiety issues. Return to our page. Authors: Jim Folk, Marilyn Folk, BScN.

Short answer: ultra super mega important.


Keep warm in the cold. Long answer: The normal body temperature of a human is around 37 Celsius, depending on where you measure it and what you re doing. A drop to 35 core temperature is defined as hypothermia. You start shivering and feeling confused and things progress from there. A body temperature of 40 is life threatening. Neither of these are enormous variances in temperature in everyday life, but for our bodies temperature is TIGHTLY controlled. It has to be! Your enzymes, the proteins that catalyse all the chemical reactions that makes your life possible, work at a very specific temperature range too cold and they don t work well enough, too hot and they irreversibly change shape and cease to work. That s called denaturation. Enzymes are also very sensitive to pH. which is why thay too is tightly controled. Even slightly more acid or alkaline blood is a sign of serious problems with your kidneys at the very least, and requires immediate medical intervention.
