Fever, also known as pyrexia or high fever, refers to a temperature above 37 degrees Celsius (normal body temperature) and is a natural reaction of the body to a variety of diseases and infections. Fever is one of the most common medical symptoms. For this reason, in this article, we will look at different types of fever in children and adults. Stay with us until the end of the article.
Why do we have a fever?
Fever is the most common side effect of illnesses such as the flu and colds. Fever indicates that the immune system is struggling with an infection or disease. In general, when the immune system produces more white blood cells to fight infection, these cells stimulate the brain to raise body temperature, resulting in fever. On the other hand, the body reacts to this phenomenon and tries to cool itself by restricting blood flow to the skin and contractile muscles, which causes chills and pain in the body and muscles.
Factors that cause fever in adults include the following:
- fungal infection;
- Sun burn;
- Bacterial infection;
- food poisoning;
- Viral infection (flu, cold).
The following diseases may also cause high fever:
- Liver disease;
- kidney disease;
- Take certain medications for a long time.
Types of body fever
Normal body temperature is between 36.1 to 37.2 degrees Celsius. If your body temperature rises above this level, you have a fever. Fever is divided into 4 groups:
- Low-grade fever: When the body temperature reaches 38 degrees Celsius;
- Moderate fever: When the body temperature reaches 39.1 to 40 degrees Celsius;
- High fever: When the body temperature reaches 39.4 ° C or more;
- Hyperpyrexia / High fever: When the body temperature reaches above 41.1 ° C.
Most fevers usually go away on their own in 1 to 3 days. However, persistent or persistent fever may recur for up to 14 days. Just as recurrent fever is a sign of a more serious infection or illness, persistent fever can be serious; Even if the fever is mild.
- If the fever lasts less than 7 days, the fever is acute;
- If the fever lasts up to 14 days, it is semi-acute;
- If the fever persists for more than 14 days, the fever is chronic or persistent.
Symptoms of fever
Symptoms of fever include the following:
- muscles pain;
- Decreased appetite.
See your doctor if you have a high fever (temperature above 39.4 ° C) or your fever was persistent and did not go away after 3 days or you had the following symptoms:
- Water shortage;
- Light sensitivity;
- Difficulty breathing;
- Muscle cramps and abdominal pain.
Treatment of fever in adults
Fever is not usually dangerous on its own. Most fevers go away within a few hours or days of the body defeating the infection. You can use the following simple and effective methods during this period to feel better:
- Take a hot shower;
- Get enough rest;
- Drink plenty of water, juices and soups to hydrate your body;
- Eat a spicy, soft diet and choose light foods.
Some over-the-counter medications can also help relieve fever and related symptoms such as headache, body aches and muscle aches. If the fever is very severe, treatment depends on the cause of the fever, and your doctor may prescribe the following medications to treat severe infections:
- Antifungal drug;
- Antiviral drug.
Proper diet to manage fever
You need to use good food to manage the fever to relieve the symptoms and get faster recovery. A balanced diet helps strengthen the immune system. Because the body burns more calories during a fever, high-energy foods are important, and a high-calorie, high-protein, low-fat, fluid-rich diet is recommended during a fever.
For the first 2 or 3 days of fever, the diet should include more fluids such as soup, water, juice, and milk (if you do not have diarrhea). Continuous small meals should be consumed about every 2 hours and gradually increased to every 4 hours. Also, eat spicy soft foods that are easily digested and absorbed to provide nutrients to your body. These foods include the following:
- Soft or mashed rice;
- Soft fruits such as bananas, papayas, apples, oranges, melons;
- Cooked vegetables (potatoes, sweet potatoes, carrots, squash).
During a fever, you need more essential nutrients such as vitamin A, vitamin C, vitamin B, and minerals such as calcium, iron, and sodium. Limit fatty, spicy and high-fiber foods that are difficult to digest and add the following foods to your diet instead:
- Fruit juice;
- Coconut water;
- Rice porridge;
- Boiled eggs;
- Lean meat;
- Cooked or steamed fish;
In case of fever, avoid the following foods:
- Spicy foods;
- Canned food;
- Fried foods;
- High fiber foods.
Fever in children and related tips
Types of fever in children
Every child may have a fever over and over again. Although fever is not in itself harmful and can be a good sign, it can not be ignored when your child wakes up in the middle of the night with a hot flush, heat or sweating. Pediatric fever may occur for the following reasons:
- Infection: Most fevers occur due to infection or disease;
- Immunization: Infants and children sometimes develop a low-grade fever after receiving the vaccine;
- Wearing a lot of clothes: Because babies’ bodies, especially newborns, do not adapt to the temperature of the environment like other children, they may develop a fever if they dress too much or are in a hot environment. On the other hand, fever in infants may be a sign of a serious infection and a doctor should check for their fever.
What is the child’s fever?
According to pediatricians, if the child’s body temperature is higher than 38 degrees Celsius, his health is in danger. Be sure to see your doctor in the following cases:
- Is less than 6 months old;
- He has not been vaccinated yet;
- Your baby’s body is warm;
- His fever lasted 3 days or more;
- There are other symptoms that may be bothering you.
In the following cases, your child may not be seriously ill:
- If he is still interested in playing;
- If he eats well and drinks well;
- Reacts to you and laughs;
- He seems to be fine by lowering his body temperature.
Do not worry if your child drinks fluids and has enough bowel movements but does not like to eat. This is normal and there is nothing to worry about.
What thermometer is best for diagnosing a child’s fever?
Digital thermometers are the best option that can be used orally, anal or axillary. For young children, it is best to measure body temperature through the anus. However, if your child is 4 or 5 years old, you can notice a fever in his mouth. Underarm temperature is not reliable, but it is easier to measure.
How to lower a child’s body temperature?
In addition to seeing your doctor, there are several other ways to lower your baby’s body temperature, including:
You can usually use ibuprofen or acetaminophen to treat a cold, which is also good for relieving pain. These medications are usually given based on the age or weight of the child. Consult your doctor if you are unsure about the dosage of the medicine.
– Medicines should not be given to children under 2 months without a doctor’s prescription;
Do not use a combination of cold and flu medicine for children. These drugs may not work well for children under 4 years of age;
– Do not give aspirin to people under 19 years of age. Aspirin use in children may increase the risk of Reye’s syndrome, a serious and rare condition. The disease sometimes damages the brain and liver.
2. Home care
- Avoid rubbing alcohol, cold water and ice on the baby;
- Make sure the baby crib is warm and not too hot or cold;
- See your doctor if your baby’s diaper is dry, has a dry tongue or mouth, or is eating poorly;
- Put on light clothes and put a light sheet or blanket on the child. Excessive covering of the child usually raises his body temperature;
- You can also use a lukewarm water bath and sponge. Of course, this method can temporarily lower the body temperature. Do not continue this method if your child is not comfortable.
3. Foods and beverages
Believe it or not, chicken soup is useful. Research shows that there is a link between eating chicken soup and reducing inflammation. The ingredients of this soup contain nutrients that help improve health and hydration. But do not limit yourself to chicken soup. Check for signs of dehydration and give plenty of other fluids. These fluids include the following:
- Solutions containing pedalite electrolyte, which should be used with a doctor’s prescription.
See a pediatrician for older children who have symptoms of dehydration (for example, do not urinate enough, do not drink enough fluids, and have abnormal functions).
4. Adequate rest
Make sure your baby gets enough rest. This does not mean that he is in bed all the time. It is enough to stay at home and not go to school or kindergarten and rest a little.
When to see a pediatrician?
You should see a doctor immediately if your child has a high fever or dehydration. However, apart from these 2 cases, in what other cases should you see a doctor? Here are a few:
- If his fever lasted 3 days or more;
- If the child under 12 months does not urinate or drink enough;
- If you suspect that your child under 12 months has the flu;
- If the baby’s nasal mucosa is green or yellow (after a 10-day period any discharge caught your eye or if discharge came out of his eyes).
Some conditions are more serious in children and you should go to the emergency room as soon as possible, which can include the following:
- Severe illness;
- Difficulty breathing;
- Not eating or not drinking;
- Symptoms of skin irritation;
- And anything that worries you.
