If your forehead is warm and your energy is low, you probably have a fever. Before you call in sick to work and swallow a couple of acetaminophen, read this.
Use these tips to understand your body temperature and treat fevers effectively.
Clearing Up Myths about Fevers
1. Understand healthy fevers
You might be surprised to learn that fever is a symptom, not an illness. It’s your body’s way of defending itself against infection.
You feel hot because blood vessels are expanding to bring the excess heat up to the surface of your skin.
2. Find your baseline
Temperature readings of 98.6F are an average figure based on the fact that your temperature fluctuates throughout the day, usually peaking in late afternoon.
Measure yourself a few times on a day when you feel well to find your normal range.
3. Monitor recurring fevers
Fevers that come and go can feel like they’re continuous. Medical tests will rule out more serious causes if you have recurring fevers.
4. Get out of bed
Did your parents order you to stay under the covers? It is okay to get out of bed if you feel good enough. Just avoid strenuous activity.
5. Call your doctor
Immediate medical care is required for infants with rectal temperatures of 100.4F or higher, or any child with a fever above 104F. Most adults will need to see a doctor for temperatures starting at 105F or additional symptoms including a stiff neck, severe stomach pain, or skin rashes.
Taking Your Temperature
Pick your method. You can take your temperature almost anywhere on your body. Older children and adults will usually get the most precise and convenient reading from an oral thermometer.
Watch your timing. Many factors can affect your body temperature. That includes eating, intense exercise, or a hot shower, so wait at least 30 minutes to ensure an accurate reading.
Follow instructions. Read the directions that come with your thermometer. For an oral reading, place the instrument under your tongue, and keep your mouth closed for the recommended amount of time, which is usually about 3 minutes.
Take care of your thermometer. For good hygiene, clean your thermometer after each use with cool water and soap. If you’re using a digital model, check the batteries, especially if it’s been stored away for a long time.
Treating Your Fever
Visit the drugstore. It’s usually safe to let a mild fever run its course, but you can treat higher temperatures and relieve discomfort with over-the-counter medications like acetaminophen or ibuprofen. Your doctor may also prescribe an antibiotic for the underlying infection.
Lower the thermostat. Keeping your house cool will help you to rest and sleep more comfortably. Keep a light blanket handy if you feel chilly.
Dress in layers. Multiple layers are better than heavy clothing or bedding that could make you sweat. That kind of rapid heat loss actually makes a fever worse.
Drink liquids. You might not feel like eating much when you’re sick, but it’s important to stay hydrated. Sip water, low sodium soup, or other beverages.
Sponge off. Taking a sponge bath while sitting in shallow water provides additional quick relief. Stick to warm water to prevent chills.
Keep your cool about fevers. Call your doctor if you or your child have a dangerously high temperature or show other warning signs such as seizures or being unresponsive. Otherwise, fever symptoms are usually a sign that your immune system is working properly and protecting you from illness.
