Which of these is a substance that reduces fever in the human body

What's the temperature in the room where you're sitting right now? My guess would be that it's not exactly 98.6 ∘ F 98.6\,^\circ\text F 9 8 . 6 ∘ F 98, point, 6, degrees, start text, F, end text / 37.0 ∘ C 37.0\,^\circ\text C 3 7 . 0 ∘ C 37, point, 0, degrees, start text, C, end text . Yet, your body temperature is usually very close to this value. In fact, if your core body temperature doesn't stay within relatively narrow limits—from about 95 ∘ F 95\,^\circ\text F 9 5 ∘ F 95, degrees, start text, F, end text / 35 ∘ C 35\,^\circ\text C 3 5 ∘ C 35, degrees, start text, C, end text to 107 ∘ F 107\,^\circ\text F 1 0 7 ∘ F 107, degrees, start text, F, end text / 41.7 ∘ C 41.7\,^\circ\text C 4 1 . 7 ∘ C 41, point, 7, degrees, start text, C, end text —the results can be dangerous or even deadly. 1 ^1 1 start superscript, 1, end superscript The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick. Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of...

Aspirin Generic name: aspirin (oral) [ AS-pir-in] Brand names: Bufferin, Durlaza, Ecotrin, Ecpirin, Miniprin, Vazalore. Drug classes: Medically reviewed by • • • • • • • What is aspirin? Aspirin is used to treat pain, and reduce fever or inflammation. It is sometimes used to treat or prevent Aspirin should be used for cardiovascular conditions only under the supervision of a doctor. Warnings You should not use aspirin if you have a bleeding disorder such as hemophilia, a recent history of stomach or intestinal bleeding, or if you are allergic to an NSAID (non-steroidal anti-inflammatory drug) such as Advil, Motrin, Aleve, Orudis, Indocin, Lodine, Voltaren, Toradol, Mobic, Relafen, Feldene, and others. Do not give this medication to a child or teenager with a fever, flu symptoms, or chickenpox. Salicylates can cause Reye's syndrome, a serious and sometimes fatal condition in children. Before taking this medicine Do not give this medicine to a child or teenager with a fever, flu symptoms, or chickenpox. Aspirin can cause Reye's syndrome, a serious and sometimes fatal condition in children. You should not use aspirin if you are allergic to it, or if you have: • a recent history of stomach or intestinal bleeding; • a bleeding disorder such as hemophilia; or • if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID (non-steroidal anti-inflammatory drug) such as Advil, Motrin, Aleve, Orudis, Indocin, Lodine, Voltaren, Toradol, Mobic, Re...

Overview A fever is a temporary rise in body temperature. It's one part of an overall response from the body's immune system. A fever is usually caused by an infection. For most children and adults, a fever may be uncomfortable. But it usually isn't a cause for concern. For infants, however, even a low fever may mean there's a serious infection. Symptoms Body temperatures vary slightly from person to person and at different times of day. The average temperature has traditionally been defined as 98.6 F (37 C). A temperature taken using a mouth thermometer (oral temperature) that's 100 F (37.8 C) or higher is generally considered to be a fever. Depending on what's causing a fever, other fever signs and symptoms may include: • Sweating • Chills and shivering • Headache • Muscle aches • Loss of appetite • Irritability • Dehydration • General weakness Taking a temperature To take a temperature, you can choose from several types of thermometers, including oral, rectal, ear (tympanic) and forehead (temporal artery) thermometers. Oral and rectal thermometers generally provide the most accurate measurement of core body temperature. Ear or forehead thermometers, although convenient, provide less accurate temperature measurements. In infants, a rectal temperature, if doable, is somewhat more accurate. When reporting a temperature to your health care provider, give both the reading and the type of thermometer used. When to see a doctor Fevers by themselves may not be a cause for alarm...

The term “chemical mediators” encompasses a wide array of substances found in various body fluids and tissues throughout the body. Chemical mediators may work alone or in conjunction with each other to inhibit microbial colonization and infection. Some chemical mediators are endogenously produced, meaning they are produced by human body cells; others are produced exogenously, meaning that they are produced by certain microbes that are part of the microbiome. Some mediators are produced continually, bathing the area in the antimicrobial substance; others are produced or activated primarily in response to some stimulus, such as the pre...

A fever is a rise in body temperature. It's usually a sign of infection. The fever itself is generally harmless and probably helpful. Fevers usually don't need treatment. The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. Your body temperature can vary depending on how active you are or the time of day. Generally, older people have lower body temperatures than younger people have. The following thermometer readings generally indicate a fever: • Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher • Oral temperature of 100 F (37.8 C) or higher • Armpit temperature of 99 F (37.2 C) or higher Should I treat a fever? When you or your child is sick, the main goal is to relieve discomfort and promote rest. Treating a fever neither shortens nor particularly prolongs the course of an illness. Treating fever in a child Children with relatively high fevers may not look or act particularly sick. Treating a fever depends on the degree of discomfort. If your child is uncomfortable or restless, these home care strategies may help: • Encourage your child to drink fluids • Dress your child in lightweight clothing. • Use a light blanket if your child feels chilled, until the chills end. • Don't give aspirin to children or teenagers. • Don't give an infant any type of pain reliever until after you've contacted a doctor and your child has been evaluated. • If your child is 6 months old or older...

When you or your child has a fever, you want something that works quickly and works well. But with so many over-the-counter (OTC) medications available, it can be tough to know which one is best for you. You can choose between two main types of OTC fever reducers: acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs include ibuprofen, aspirin, and naproxen. In general, no particular one of these fever-reducing drugs is better than the others. Instead, you should compare the drug forms, side effects, and other factors to choose a fever reducer that will work well for you or your child. Here’s what you need to know to make an informed decision. Acetaminophen is a fever reducer and a pain reliever. It’s not fully understood how this drug works. Acetaminophen doesn’t decrease swelling or inflammation. Instead, it likely changes the way your body senses pain. It also helps cool your body to bring your fever down. Forms and brand-name versions Acetaminophen comes in several forms. These include: • tablets • extended-release tablets • chewable tablets • disintegrating tablets • capsules • liquid solution or suspension • syrup You take any of these forms by mouth. Acetaminophen is also available as a rectal suppository. Common brand-name drugs that contain acetaminophen include Tylenol, Feverall, and Mapap. Side effects When taken as directed, acetaminophen is generally safe and well-tolerated. However, in some cases, it can cause side effects such as: • nausea ...
