How Does Stress Affect Body Temperature?
It's Getting Hot in Here!?
By: Lorena Barrera and Sara Broggi
We found out that our Hypothesis was correct, it does affect you body temperature because of your blood and your body. Because your body and brain becomes very anxious.
We think that it does affects your body temperature. Because the more you get stressed out the higher your blood pressure rises and your blood heats up and changes your temperature.
Work Sited


1. Design a very challenging test to give to your test subjects. For example, you could create a multiplication test with many questions and ask test subjects to complete the test in just five minutes. Tell test subjects that they will receive a reward if they are able to complete the test perfectly within the time frame.
2. Before starting the test, ask the participant to rate his or her stress level on a scale of one to ten.
3. Ask the test subject to sit quietly for five minutes before taking the test.
4. Take and record the subject’s basal body temperature
5. Ask the test subject to take the test.
6. Immediately after the test, repeat the basal body temperature measurement and ask the test subject to rate his or her stress level on a scale of one to ten.
7. Repeat steps 2 to 6 with approximately ten test subjects.
8. Analyze your results. Do you notice changes in your test subjects’ body temperatures after they took the challenging test? If so, how much did temperature change on average? Did test subjects who rated a higher increase in stress level exhibit larger temperature fluctuations

What happens inside your body
When you are stressed, your body releases a flood of adrenaline, cortisone, and other stress hormones that induce physiologic changes. The heart pounds and blood pressure rises. You start to breathe more rapidly, and you feel more alert. Blood races to your brain and heart and moves away from the kidneys, liver, stomach, and skin. Your blood sugar level rises, as do the amounts of fats and low-density lipoprotein (LDL) cholesterol, also known as bad cholesterol, in your bloodstream.

Common things that causes stress
•Family gatherings
•Losing your job
•Health problems
•Having kids
•Aggressive and rude people
•Getting married
The death of a family member, partner or close friend
Having a long term illness
Being bullied or picked at work or school

Scientific Question

This experiment will investigate if stress alters body temperature.
Normal body heat
In the US, normal human body temperature is often said to be 98.6F degrees. In other places, like Russia, the commonly quoted number is 36.6 Celsius, which is 97.9F. Why the difference? Both numbers come from the same source, in which a German study found that the average body temperature was 36.6 degrees Celsius.
What is Blood pressure ??
Force originating when the heart's pumping pushes the blood against the walls of the blood vessels. Their stretching and contraction help maintain blood flow. Usually measured over an arm or leg artery in humans, blood pressure is expressed as two numbers; normal adult blood pressure is about 120/80 mm of mercury.
Does stress affect body temperature?
We found people that where really stressed out. We took their stressed temperature and I compared it to the normal human body temperature. So that i can see the difference between someone stressed and when not stressed. To see if when someones stressed really affects their body temperature.
Stress stimulates the release of hormones that affect the body in a variety of different ways. In the experiment, It will evaluate whether changes in body temperature can be detected when people are placed in stressful situations.
