Why fever is your friend and what to do if you have one


When you’re sick, a fever can be your friend. It signals that your body is working hard to fight an infection, and the rise in body temperature may help it do so more effectively. But how do you know if it’s time to call the doctor? And what should you do if your fever persists or gets worse? We’ll explain these questions and more in this guide. Here is our guide on “Why fever is your friend (and what to do if you have one)”:

A fever is often the first sign of illness.

Fever is the body’s response to an infection. It can be a good sign that your immune system is working. But if you’ve had a fever for more than two days and your symptoms aren’t improving—or get worse—you should see a doctor. Some types of fevers are caused by bacteria or viruses (like the kind that causes colds). But some are caused by something called pyrogens: chemicals released into your body during infections that cause inflammation and raise the temperature of blood vessels around them.

Fever is common among children under five years old because their immune systems aren’t fully developed yet; adults often have high fevers at times when they get sick because they have stronger immune systems than children do (10).

Most fevers respond well to rest, fluids, and over-the-counter medicines.

Most fevers respond well to rest, fluids, and over-the-counter medicines.

  • Rest: If your child is in an uncomfortable position (lying down or sitting up), try to keep him or her still for as long as possible. This will make it easier for the body to get rid of excess fluids and fight off illness.
  • Fluids: Give your child enough liquids that are easy on their stomachs (like Pedialyte) but not so much that they’re feeling sick later—just enough so that they aren’t becoming dehydrated after vomiting or diarrhea.
  • Over-the-counter medicines: If you have symptoms from something other than a fever (like sore throat), check with your family doctor before taking any over-the-counter medicine; he might recommend a prescription alternative instead.*

In most cases, you don’t need to do anything to lower your fever.

In most cases, you don’t need to do anything to lower your fever. If you have a high temperature and feel sick, rest and drink plenty of fluids are typically enough for the body to fight off the infection on its own. You can also use over-the-counter fever reducers such as acetaminophen or ibuprofen if needed.

If you do have an infection with symptoms like chills or nausea that last longer than three days (and especially if there’s no improvement after two days), it might be worth talking with your doctor about whether they think it’s necessary for them to treat your illness. Particularly if they’re concerned about possible complications related specifically to the virus causing this condition.

When your body temperature rises, it can be a sign that your immune system is doing its job.

When you have a fever, your body is fighting an infection. Your immune system is working hard to kill off the virus or bacteria that caused it in the first place. The more fever you have, the better this works. But this can also be dangerous if your temperature goes too high or past 101 degrees Fahrenheit (38 Celsius).

If you’re sick with something like flu or bronchitis and are taking anti-viral medications at home, your doctor may tell you that your temperature should come down before they prescribe stronger doses of medicine for additional relief. If not, then perhaps some other measures will help get things under control:

  • Drink plenty of fluids so that your thirst is satisfied but not so much as to make yourself feel faint
  • Try adding ice packs wrapped around neck or wrists if possible

Sometimes you should call your doctor right away if you have a fever.

  • If you have a fever, it’s important to call your doctor right away. Your doctor may ask you questions about what time of day and how long you’ve had the fever, as well as other details about your illness.
  • Pregnant women should see their doctors if they have any signs of pregnancy-related complications such as morning sickness or excessive vaginal bleeding.
  • Someone who is having trouble taking care of themselves can also call 911 immediately if they believe that they’re suffering from an emergency like choking or difficulty breathing (which could indicate pneumonia).

Body temperature rises when the immune system is fighting an infection and this can be a good sign.

Fever is a sign that your body is fighting an infection. It can be a good thing if you have a fever! Because it means the immune system is working properly and fighting off germs. If you have the flu or some other type of infection, then the fever will last for about 3-4 days. After that symptoms begin to disappear (the duration depends on how severe the infection was). However, if your immune system has been weakened by drugs or other factors such as cancer treatment, then this can prevent it from working properly.

When you have a high temperature due to an illness like malaria – which causes fevers ranging from 103 degrees F (39 C) up into 104 F (40 C) – then doctors recommend keeping fluids down until they fall below 100F (38C).


It’s important to know that your body temperature is a sign of your immune system working hard. A fever is not always dangerous—it’s just something that happens sometimes. If you have a fever, don’t worry too much about it! Try to stay as comfortable as possible until it goes down naturally with rest and fluids. If you feel sick enough for doctors to recommend antibiotics or other medications, then get them as soon as possible so you can get better sooner!
