Bosy Temperature Affecting Hunger

After a long hard work out, human’s body temperature goes up. Does high body temperature from exercise increase or reduce hunger? If high body temperature reduce hunger, it can help many people who cut their diets from preventing overweight. Many can just exercise and automatically have their hunger reduced, instead of forcing starvation, which leads to dangerous effects. People’s thoughts are that after exercising, hunger is increased. To test the problem, will record body temperature after exercising for about 30 minutes.

Next, calculate the amount of calories eaten within the hour. Lastly, compare calories eaten with high body temperature and calories eaten with normal body temperature. This should prove if high body temperature reduces hunger and the difference of calories eaten.

It is not the exercise that causes appetite, it’s the heat generated by the exercise. The connection between exercise and appetite suppression lies in the arcuate nucleus portion of the hypothalamus. Arcuate nucleus contains appetite-suppressing POMC neurons. POMC stands for proopiomelanocortin.

About 66% of the POMC neurons also have TRPV1 receptors. TRPVI stands for transient receptor potential vanilloid 1. The receptors are sensitive to heat and capsaicin (component of chili peppers that produce a burning sensation). Researchers proved that the TRPV1 receptors in the POMC neurons detect the body temperature increasing caused by exercising with mice. Detection by the TRPV1 receptors activates the neurons which causes a reduce in hunger. Although the test with the mise prove that the connection between the temperature in the hypothalamus and appetite suppression may not work the same as humans.

The appetite-control system in humans is not fully understood, but if the results of the mice occur the same with humans then it will opens up new areas into the relationships between exercise, food intake, and weight control.

The hypothalamus controls the hormones control appetite. It is a small brain region near the base of the spinal cord, it play a big role in hormone regulation. Hypothalamus contains many important centers that control body temperature, hunger, and thirst. It exerts overall control over the sympathetic nervous system. It increases the heart rate, breathing rate, and blood flow to the muscles. Groups of nerve cells in the hypothalamus control the body temperature. Some of the nerves are sensitive to heat and cold, so when blood flowing to the brain is hotter or cooler than normal, the hypothalamus switches on temperature mechanisms. The hypothalamus receives information from internal sense organs regarding the body’s water content and the level of glucose in the blood. If they are too low, the hypothalamus stimulates thirst and appetite for food.

Scientists studied mice by having them run, then measured their food intake afterwards. Scientists discovered that reduced food intake was associated with a hypothalamic temperature of about 39 C. It is a step up from the normal mouse body temperature of 37-38 C. Based on the results of the experiment with the mice, it seem like any change in body temperature should result a change in appetite.

Blood-brain barrier protects the brain from potential poisons that might be circulating the blood. During that process, the blood-brain barrier also protects the brain from heat in the blood stream. There are some cells that dangle outside the protective barrier, the dangling cells might sit in the right place to sense temperature and respond to the tiny fever that animals get.

My hypothesis is that high body temperature due to exercise may reduce hunger. I believe that appetite is reduced after exercising because of the results of the mice that were tested to learn about the information. Mice and humans are both mammals and have the brain cells that cause what caused the mice to reduce appetite. After I learned about the background of the brain, humans have the same, so why can’t the same happen for us.
