Fever is a natural response of the body to fight off infections or illnesses. When the immune system detects an invader, it releases chemicals that raise the body’s temperature. This increase in temperature helps to kill the virus or bacteria, as they are unable to survive in higher temperatures. Additionally, fevers stimulate the production of white blood cells, which are crucial for fighting off infections. While fevers can be uncomfortable, they are usually a sign that the body is actively fighting an infection. It is important to monitor fevers and seek medical attention if they become too high or last for an extended period.
Do you recall the most recent instance when you fell ill? It might have initiated as a queasy stomach or a throat ache accompanied by coughing. However, eventually, you might have started feeling extremely fatigued and uncomfortably warm. Placing your hand on your forehead confirmed what you suspected: a sweaty forehead that felt significantly hotter than usual.
What are we referring to? A fever, of course! A fever is a definite indication that your body is combating something and probably requires medication.
Typically, human beings possess a normal body temperature of around 98.6º F. Some individuals may have a normal body temperature slightly higher or lower than this value. Additionally, your temperature may naturally fluctuate throughout the day, being slightly lower in the morning and a little higher in the evening. Nevertheless, a deviation above 98.6º F generally indicates the presence of a fever.
The body’s temperature is regulated by a brain component known as the hypothalamus. Located in the brain’s center, the hypothalamus acts as the body’s thermostat. It monitors changes in your body temperature and sends signals to different body parts to maintain it at the appropriate level.
So, how do fevers come about? They are usually caused by the invasion of germs, such as bacteria and viruses. Germs can introduce specific chemicals into your bloodstream, making you feel unwell. When the hypothalamus detects these chemicals in your blood, it communicates with the rest of your body to increase your internal thermostat.
For instance, instead of the usual 98.6º F, your hypothalamus might instruct your body to elevate its temperature to 102º F. Although experiencing a fever is not pleasant, raising your body’s temperature aids in combating the germs that are making you sick by creating an uncomfortable environment for them. Additionally, a fever informs you that you have an infection that requires treatment.
Upon developing a fever, you often experience slight shivering at first. Shivering is one of the ways your body generates more heat to reach the new, higher temperature set by the hypothalamus. Once your body reaches its new temperature, you will feel sufficiently warm.
As soon as your body manages to eliminate the germs, usually with the help of medication, your hypothalamus will readjust your body’s thermostat back to 98.6º F. You will likely start sweating more as your body uses perspiration to cool down to the correct temperature.
Most fevers resolve naturally. However, fevers in very young infants can be particularly perilous. Additionally, extremely high fevers of 104º F or higher in children might also necessitate contacting a doctor.
For most common fevers, over-the-counter medications like acetaminophen and ibuprofen can help alleviate the fever. If you have a fever, it is also important to consume plenty of fluids. As your body temperature rises during a fever, dehydration can occur easily, so make sure to drink ample fluids and get some extra rest.
Give It a Try
Phew! Today’s Wonder of the Day was a real scorcher! Cool down by exploring the following activities with a friend or family member:
- Do you currently have a high body temperature? The only way to find out is by taking your temperature. Request assistance from an adult or family member to use a thermometer. What is the result? If your temperature is around 98.6º F, then you are fine. If it is slightly higher, you may have a fever. Try taking your temperature twice a day for the next week. Does your body temperature remain constant or does it fluctuate? If it fluctuates, how much does it usually vary?
- What is the most common fever treatment used by your family? Ask an adult or family member to help you check the medicine cabinet for fever remedies. Look at the labels of different products to see which ones can be used to combat a fever. If you are interested, visit a local pharmacy and speak to a pharmacist about other options for fever treatment.
- Are you up for a challenge? Think of innovative ways to combat a severe fever. In certain emergencies, doctors have to rapidly cool down the body to fight fevers. They may use cold water or even place ice directly on the skin. Can you think of any other ways to quickly cool off? Use your imagination and be creative. Share your ideas with friends and family. What ideas do they have? Did you come up with any ideas that could be effective in an emergency situation? Why or why not?
FAQ
1. Why do we get fevers?
Fevers are a natural response of our body’s immune system to fight off infections and illnesses. When our body detects the presence of harmful bacteria or viruses, it releases chemicals that raise our body temperature. This increase in temperature helps to create an inhospitable environment for the pathogens, as they thrive at lower temperatures. The higher body temperature also stimulates the production of more white blood cells, which are essential for fighting off infections. Therefore, fevers are a sign that our immune system is working effectively to combat the illness.
2. Are all fevers a cause for concern?
No, not all fevers are a cause for concern. In fact, fevers are often a sign that our immune system is functioning properly. Most fevers are a result of common viral infections, such as the flu or a cold, and they typically resolve on their own within a few days. However, there are instances when a fever may indicate a more serious underlying condition, such as a bacterial infection or inflammation. It is important to monitor the duration and intensity of the fever and seek medical attention if it persists for an extended period of time or is accompanied by other worrisome symptoms.
3. Can fevers be dangerous?
While fevers themselves are not usually dangerous, extremely high temperatures can be a cause for concern, especially in young children and older adults. Prolonged fevers above 104°F (40°C) can lead to complications such as dehydration, seizures, or confusion. It is important to take measures to reduce the fever, such as drinking plenty of fluids and using over-the-counter fever-reducing medications like acetaminophen or ibuprofen. If the fever persists or worsens despite these measures, it is recommended to seek medical attention.
4. How can fevers be managed at home?
Fevers can be managed at home by following a few simple steps. First, it is crucial to stay well hydrated by drinking plenty of fluids like water, herbal tea, or clear broths. Dressing in lightweight clothing and keeping the room temperature cool can also help to lower body temperature. Over-the-counter fever-reducing medications, such as acetaminophen or ibuprofen, can be used following the recommended dosage. However, it is important to note that these medications only provide temporary relief and do not treat the underlying cause of the fever. If the fever persists or is accompanied by other concerning symptoms, it is advisable to consult a healthcare professional.
5. When should I seek medical attention for a fever?
While most fevers resolve on their own within a few days, there are certain situations when it is advisable to seek medical attention. You should consult a healthcare professional if the fever persists for more than three days, is accompanied by a severe headache, abdominal pain, difficulty breathing, or a rash. Additionally, if the fever is extremely high (above 104°F or 40°C), or if it is present in infants under three months of age, it is important to seek medical attention promptly. A healthcare professional will be able to assess the underlying cause of the fever and provide appropriate treatment if necessary.
