A fever can come out of nowhere, leaving you sweaty, achy, and feeling completely off your game. While a fever itself is often just the body’s way of fighting off an infection, knowing how to properly manage it—whether at home or with medical care—is key. This guide will walk you through the essential steps to handle a fever, help you decide when to treat it at home, and understand when it’s time to seek professional help.
By the end of this read, you’ll have a better understanding of how to care for yourself (or a loved one) when fever strikes, and you’ll feel more in control of your health.
What Is a Fever and Why Do We Get It?
First, it’s important to understand what a fever is and why it happens.
A fever is your body’s natural defense mechanism. When your internal thermostat (controlled by the hypothalamus in your brain) detects an anomaly—usually caused by viruses, bacteria, or other invaders—it raises your body’s temperature to create an environment that’s less hospitable for harmful pathogens.
Typically, a normal body temperature sits around 98.6°F (37°C). If your temperature reaches 100.4°F (38°C) or higher, it’s classified as a fever.
But a fever is more than just an elevated number—it may come with accompanying symptoms like:
- Chills or shivering
- Muscle aches
- Fatigue
- Sweating
- Rapid heart rate
While a fever is often harmless, it’s important to know how to differentiate between manageable fevers and ones that require medical intervention.

When to Treat a Fever at Home
Not all fevers signal a medical emergency. Minor fevers—often caused by common viral illnesses like a cold or the flu—can be treated comfortably at home with proper care. Here's a step-by-step guide on how to treat it yourself.
Step 1: Measure Your Temperature Accurately
To manage a fever effectively, start by knowing the facts. Use a dependable thermometer (preferably digital) to measure your body temperature. Oral, rectal, and ear thermometers tend to be more accurate than forehead strips.
Pro Tip: Check the temperature at regular intervals, especially if symptoms worsen.
Step 2: Stay Hydrated
When you have a fever, your body loses water faster than usual through sweat. Dehydration can make you feel worse and even prolong your illness.
- Drink plenty of fluids such as water, electrolyte drinks, herbal teas, or diluted fruit juice.
- Avoid caffeine and alcohol, as these can dehydrate you further.
Step 3: Take Fever-Reducing Medications
Over-the-counter medications like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) are highly effective at reducing fever and alleviating discomfort. Always follow the recommended dosage on the label.
Caution: Never give aspirin to children or teenagers with a fever, as it increases the risk of a rare condition called Reye’s syndrome.
Step 4: Dress Comfortably
It might sound counterintuitive, but don’t bundle up in thick blankets or heavy clothing when you’re running a fever. This traps heat and can make you feel worse. Instead, wear lightweight clothing and use a breathable sheet or throw.
Step 5: Rest Up
Your body fights infections best when it’s not overexerting itself. Make sure to give your body the downtime it needs to recover. Sleep is your strongest ally!
Step 6: Use Cool Compresses
If you’re feeling especially warm, applying a cool washcloth to your forehead, neck, or wrists can provide soothing relief. This method works by drawing heat away from the skin.
Bonus Tip for Natural Remedy Seekers
Many health enthusiasts swear by natural remedies for fever. Ginger tea, peppermint tea, and lukewarm baths infused with apple cider vinegar are all popular options. However, proceed with caution and consult your doctor if you’re unsure about any remedy.
When to Seek Medical Help
Not all fevers can (or should) be managed at home. Knowing when to seek professional care is crucial for ensuring your safety.
Symptoms That Require Immediate Attention
Contact your doctor or seek emergency medical help if you or someone you’re caring for experiences any of the following:
- A fever above 103°F (39.4°C) in adults or 102°F (38.9°C) in children
- Persistent fever lasting longer than 3 days
- Severe headaches or unexplained rashes
- Shortness of breath or chest pain
- Repeated vomiting or inability to keep liquids down
- Signs of confusion, disorientation, or seizures
Fever in Infants and Children
Fevers in infants require special attention because their immune systems are still developing. Seek immediate medical care if:
- Your baby is younger than 3 months and has a rectal temperature of 100.4°F (38°C) or higher
- Your child aged 3–12 months has a temperature of 102°F (38.9°C) or higher
- The child has difficulty eating, is listless, or is unusually irritable.
Fever With Underlying Health Conditions
Adults or seniors with chronic illnesses (like diabetes, heart conditions, or a compromised immune system) should err on the side of caution. A fever can exacerbate underlying health issues rapidly in these cases. Check in with your healthcare provider.
How to Prevent Fevers
While it’s impossible to avoid every illness, some habits can reduce your risk of developing a fever-inducing infection:
- Wash your hands frequently (especially during flu season).
- Stay up-to-date with vaccinations, including annual flu shots.
- Boost your immunity with a balanced diet, exercise, and adequate sleep.
- Avoid close contact with sick individuals when possible.
- Ensure proper food safety hygiene when cooking and eating.
Prevention is the best defense—and these steps will help keep your immune system in tip-top shape.
