  1. I likes the article I think it was very informational. I think that having a fever will increase your heart rate because your body is trying to fight the fever so I do believe it might affect your pulse just because your heart rate is up. I have had fevers before and I don't think that it ever affected my breathing. Some damaging effects of the fever are that people try to fight it off right away, we'll doing that destroys your immune system because they take ibuprofen. A be idiot of having a fever is that it is the body's natural way of fighting off diseases.

  2. The body is incredible, from regulating core temperature to send blood on a 60,000 mile journey everyday. When you contract a fever you blood vessels dilate, blood pressure increases and your pulse accelerates. I would assume that respiration would increase because the lungs have to compensate and oxygenate all of the extra blood circulating. Fevers, those over 105F, can cause severe brain damage in a matter of minutes. This article has helped me understand the origins of fevers and the body's response to environmental temperatures.

  3. Although severe and abnormal fevers are something to be cautious about, the article states that "for most people moderate fevers probably serve to boost the host defenses and speed recovery," and have "a beneficial effect on the outcome of infections." Studies have shown that not all fevers are bad, like what most people consider a harmful affect on the body, instead it is in fact the body's way of helping itself. Moderate fevers we get are actually helping to fight infections and enhance our immune responses. With a fever a person's pulse, respiration, and blood pressure would increase.

  4. All biochemical changes are affected by temperature changes. Depending on what our body temperature is, our metabolic rate speeds up or slow down to accommodate our bodies. This is largely controlled by the hypothalamus. A fever is induced by the release of endogeneous protein, which is the response to coming into contact with a pathogen. This articles shows that fevers are, indeed, beneficial to the body. They are practical as a "readily available index of health status."

  5. I think this article is very informational especially for some people who might not have very much access to the medical world. This article helps people better understand what a fever means, and other facts about your core body temperature. Our body is a very intriguing machine that does many things inside that often goes unnoticed. Most people don't know that shivering is your bodies natural response to cold or that sweating actually cools your temperature. This article gives great insight to these things and does a great job explaining these phenomenon.

  6. This article is very informational. I believe that the higher your body temperature is it will affect your heart rate which will increase your pulse. I have never really had a fever that could affect your breathing, but it could be possible. Some people ignore their fevers, but some of them are so severe that it could damage your brain. If you have a fever you need to go to the doctor so you can figure out the right treatment to control and bring it down. Sometimes if you have a fever it's not exactly a fever it could be something else. This article has helped me learn more about how fevers come about and the effects they have on the body.

  7. I think the fever will raise the pulse. Breathing will most likely increase to try to get rid of the heat the fever causes. I also think blood pressure will rise also. Heart conditions can be dangerous with a fever.

  8. The article made some points about fevers I never thought of. I think that a fever would increase your pulse because your body temperature is higher. Heat opens your blood vessels and lets your blood circulate better, which makes the heart work harder.fever shouldn't cause a lot of respiratory problems.Bloodpressure would probably go up because of the stress on your body.A fever helps get rid of the viruses and bacteria in your body.It can also be bad if your pregnant because a fever can cause birth defects.

  9. A fever is basically when the temperature in your body begins to rise. This temperature is controlled by the hypothalamus. The hypothalamus is like your own thermostat. When your temperature begins to rise, then your white blood cells begin to work faster to fight your infection. The normal temperature of your body should be 37 degrees Celsius, but if it rises to 40 degrees Celsius it can cause neurological damage. To help control fever you can take a antipyretic. All in all your fever is an important function of your body and without it, it would be hard to fight off infection.

  10. I think some people over react about fever. I also think some people don't take fever serious enough. Fever could also turn into a serious illness I think this article is to inform people to what is right and wrong and what it is that way the next time you know what you should do to get back healthy as soon as possible !

  11. I think the article is very informative and interesting. I believe that fever could increase your heart rate and blood pressure. I do not believe it could affect your breathing, however breathing could change as a effect of illnesses that typically accompany fever. A possible damaging effect of fever, would be if the body temperature reached over 40 degrees Celsius. This could cause neurological damage. This article has helped me understand what a fever truly does and what it is caused by.

  12. Your body wants to stay in a state of equilibrium. So when your body may need to change the internal temperature It causes your body to rise or lower in temperature through the brain by sending it messages.
    Your body will release proteins to fight some viruses and bacterias that in return raise you're temperature. And fever regulates body temperature.

    Your body will rise or lower in temperature through the brain, by sending it messages from the body. Fever regulates body temperature. Your body will release proteins to fight some viruses and bacterias that in return raise you're temperature. Fever has adapted to help the host with infection.

  14. I feel like this article gave off some great information. I guess some people take their fevers serious and some are just blunt. A fever is when the temperature of your body rises. Fevers can turn into a serious illness at times. When you get a fever your white blood cells work harder and harder.

  15. A fever has evolved as an adaption to reduce the severity of infection. All biochemical processes are affected by changes in temperature. The ability to maintain a relatively constant temperature has allowed us to to be relatively free of the influence of fluctuations in the temperature of our environment. Our bodies have their own way of warming themselves up or cooling themselves down to maintain a constant body temperature. Studies have shown that small elevations in body temperature, similar to those during a fever, result in an enhancement of the immune response. So, statistically, fevers are beneficial. People with fever, who also have other medical problems may see that a fever could worsen their condition.

  16. I personal ally enjoyed this article. I think it was very helpful in understanding fever and how it effects the body. Fever can damage the body but can also help make it stronger after recovery. It helps the immune system when dealing with any illness and makes it more difficult to become sick sometimes.

  17. It can be both helpful and harmful for a child's well being, it's harmful by being dangerously hot for a baby's unprotected brain. It does help by making the body stronger and able to prevent future illness of that extreme. The body is trying to maintain equilibrium by raising and lowering the body temperature ?

  18. I believe that the higher your body temperature is it will affect your heart rate which will increase your pulse. According to this article fever can effect your breathing. Most people ignore their fevers, but some of them are so severe that it could damage your brain. Your body will rise or lower in temperature through the brain, by sending it messages from the body.

  19. The article was informative and helped me to form an educated opinion of the subject. I believe that fevers, as long as they are strictly monitored can be beneficial to the individual affected. This is because, the fever helps to heat the body to fight off the infection, it also helps to activate the white blood cells; thus giving an alternative to artificial antipyretic medications. However, there are downsides to fevers, if the fever raises the body temperature too high the individual runs the risk of having permanent brain damage.

  20. I liked this article especially the part where it says fevers have a beneficial effect on the outcome of infections and that it can make the body stronger and serves to boost host defenses and speed recovery.

  21. Our brains r meant to handle a certain temperature and if it goes below or above the temperature then it's dangerous and harmful for the brain itself.

  22. Your body heats up due to a bacterial infection. Your body can also heat up due to your metabolic rate. Some people become immune to a fever and don't realize they even have one. When your body becomes exposed to heat your body absorbs the heat and can increase your blood stream. The ancient people said that if you got a fever your body was trying to cook the poison out of your body and fight Infection. There are even some types of cold blooded animals that can run fever. When to your u r body is cooled down then your blood began to slow down and shivering begins. The same medicine used in pain reliever are also used in fever reducers.

  23. In this article the writer gave you a lot of good information on fevers that can be very helpful. I believe that a fever will raise your blood pressure. That is because you body is trying to get more blood to the injured or infected area, and because of this your pulse will raise too so that it can pump more blood out to those areas. Your respiration should also raise too. This is because you pulse has gone up so your body is doing more work and it needs more oxygen to function properly. Most fevers are beneficial because it helps fight off infection, but if your fever gets too high it can damage your organs and be potentially fatal.

  24. I really liked this article. It taught me a lot of different things about a fever that I've never known before. It gave very believable information that made you question whether or not fever is always an indication of an illness. I think it was funny how in ancient times, they thought that a fever cooked the infections out of a persons body and that they taught based on that for years.

  25. I like this article but then I don't think that a fever is good for the body because if it gets to hot you can die. Even though when you get in a sauna or a hot tub of some sort you can have really bad problems with your body if your in too long. Too much sweat is probably a bad thing.

  26. Personally, I like this article because it has useful tips about fevers you should know about. Like the body has a "set point" temperature and if it reaches above or below this point the body with begin to create sickness. Sometimes your heart rate can cause you to have a fever. But how a fever a comes about is when you have a bacterial infection.

  27. If a fever gets over 40 degrees celcius, there could be neurological problems. The beneficial outcomes of having a fever is the activity of white blood cells, increased mobility and activation of T lymphocytes.

  28. When you have a fever your blood pressure and pulse increases. Moderate fevers enhance the immune system and helps fight infections, but if a fever reaches over 40°C it could possibly cause neurological damage.

  29. A fever has developed as an adaption to minimize the cruelty of the infection. The ability to keep a constant temperature allows us to be relatively worry free of influence of variations in the degree of temperature in our domain. Studies have shown that little advances in body temperature conclude in an improvement of the immune outcome.

  30. Even though a fever can be somewhat beneficial, it still is harmful. When you have a fever your body's temperature rises. Which can result in a far more serious illnesses. Your bodies temperature is controlled by your hypothalamus, when you get a fever your white blood cells try to fight the infection and bring your bodies temperature back to 37 degrees celsius

  31. This article was interesting because it shares important facts and information about fevers that is not always known by a numerous people. For example, I didn't know there was benefits out of having a fever, and now I know a fever has evolved as an adaptation to reduce the severity of infection meanwhile is below 40 C. This article also explains different way to gain or to lose heat which might be helpful for the readers in different situations.

  32. I liked the article actually it was very informational. I believe that I learned something very valuable about fevers. I like how it could befit the person infected but it can be harmful in ways also. Your body temperature is controlled by hypothalamus,so when you get a fever your white blood cells try to fight off the infection and bring the temperature back to the normal temperature.

  33. I predict that fever will cause respiration and heart rate to go up while lowering blood pressure. If core temperature get's to high there is a risk of neurological damage. However, there are also benefits of a fever. Small rises in temperature enhance the immune response causing increased mobility of the white blood cells.

  34. Sometimes, a fever can be beneficial to the human body. For example, when a person has a low fever it can be beneficial to their body because when ones body temperature rises their white blood cells start working even harder to possibly fight an infection. In other words, low fevers serve to boost host defense and speed up recovery. Other times a fever is not beneficial to a persons body because an extremely high fever can cause serious problems such as birth defects in pregnant women.

  35. This article was very informative and helped me gain knowledge on fevers I wouldn't have been aware of. Fevers can at times be helpful but can be hazardous if not treated properly. Fevers can also be very harmful, fevers can change your heart rate and and increase your blood pressure, so a fever is something you should watch and take proper care of.

  36. This article about fevers showed me that fevers can fevers can be beneficial and not so beneficial to you. Studies have shown that small elevations in the body temperature result in an enhancement of the immune response. They can increase mobility and activity in white blood cells, stimulate of interferon production and function and activation of T lymphocytes. In individual cases, fever may be maladaptive. It could cause increased incidence of birth defects while pregnant, but most fevers serve to boost host defenses and speed recovery

  37. A fever is something that is caused by a bacterial infection and is often overlooked by most people. Fevers can be helpful and harmful. Speeding up recovery is one of the few things that fevers can help; however, more severe fevers can cause brain damage. In my opinion I believe that overall fevers are beneficial to the body but should be monitored and watched very closely so that they can't become too severe.

  38. I like this article, it informs a lot of people about temperature of your body and how it can be somewhat beneficial to your body but also not good for you. It tells you about the regulations of your body temperature and how your metabolic rate speeds up or slows down depending on whether body temperature is rising or falling. It also talks about how there studies that show that changes in temperature like fever result into a enhancement in the immune response. Which not a lot of people know about.

  39. I also think that the article is very informational. It helps you understand better what your body is doing when you have a fever. They can increase your heart rate because your body is trying to fight off the fever so it makes your pulse go up higher. Having a fever can also increase your blood pressure as well. But if it is 99.8 that isn't high enough to raise your blood pressure.

  40. A fever is your body's natural response to something abnormal like an infection. The body temperature rises and your white blood cells are now working to defeat the problem. A fever is also a key symptom for doctors to help diagnose you. Any temperature above 98.6 degrees F could be considered as a fever. A high (100.0+) fever is dangerous and could cause cardiovascular and neurological problems. I think a fever is a positive effect on the body. You may not feel this way but when you are burning up and not feeling well, but your fever could be the reason your doctor determines the diagnosis!

  41. A fever is your body's response to fighting an infection or illness that you may have caught. Being a positive effect, a fever lets you know that "Hey, something is going on but we're doing the best we can to fix it."
    You may not feel very good but the faster your fever leaves the faster you'll get better because the infection or illness is gone.

  42. The regulation of body temperature affects multiple forms of life such as "birds, mammals, and some species of insects to be free of influence of fluctuations...of the environment." Heat stabilizes the body and is easily lest from the surface of the skin. Sweat is a process that releases heat and evaporates to cool off the body. Fevers are useful to the body by raising the natural temperature to fight off diseases. Another name for raising the temperature is hyperthermia. Hyperthermia is not the same as a fever. In conclusion it is statistically shown that when a body has a natural fever it is beneficial.

  43. The normal temperature of your body should be 37 degrees Celsius if it rises to 40 degrees Celsius it can cause neurological damage. A fever is when the temperature in your body begins to rise. The temperature is controlled by the hypothalamus which is like your own thermostat. Your fever is an important function of your body, without it, it would be hard to fight off infection. When your temperature begins to ride then the white blood cells in your body work faster to fight your infection.

  44. A fever can be both good and bad for your body. If the fever is too high then it can be bad, and the same affect if it is too low. The average body temperature for the human being is 98.6 but may vary. If you have a fever (change in internal body temperature) then you are no longer in the state of homeostasis. In the instance of a fever, your heart rate may rise not so much in a low grade temperature as in a higher grade temperature. This means a rise in your breathing rate and blood circulation; this is your body attempting to fight off the fever. This article gives a good deal of information, and good information at that. I just wish that they would've explained their point a little more.

  45. This article has useful tips for fever. A fever tells you that you have some kind of infection in your body. A temperature over 100 is dangerous and could cause cardiovascular and neurological. A temperature above 98.6 degrees is could be consider a fever.

  46. Of course I find this article very informal. It's amazing how the body reacts to many things to regulate and heal itself, and I find it pretty interesting how a fever has evolved as an adaptive host-defense response to infection, and the reason you get colder while having a fever is because your blood and body has not adapted to the rise of the body temperature, but of course not always is a fever a good thing, as in hypothermia. It's a good way of recognizing the sickness, but the sickness itself isn't a very fun experience. A higher fever, especially for children or kids is not a good sign.

  47. I find it pretty astounding that the human body can react to things by causing things such as a fever and essentially benefit from the heightened body temperature

  48. I think this article gives very helpful information. I have learned that while a fever can damage your body in a way, it can also help make your immune system stronger.

  49. I personally think fevers are more bad than good depending on the age. If babies get fevers they have a higher risk of dying
