What Causes Fever in Adults?
A fever is the body’s natural response to bacterial or viral infections, signaling that your immune system is actively fighting off invaders. By raising your body temperature, your system creates an inhospitable environment for temperature-sensitive bacteria and viruses.
Fevers are commonly associated with illnesses like colds and flu and often resolve on their own within a few days.
Tips for Managing Fevers in Adults
While most fevers are not serious, knowing how to manage them is essential. Always consult your doctor if you have any questions or concerns.
Stay Hydrated
Drink plenty of water to prevent dehydration and help lower your body temperature.
Rest
Your immune system is working hard to combat infection, so be sure to get adequate sleep to aid recovery.
Eat Light
Choose easy-to-digest foods like crackers, broth, and soup. Avoid dairy products such as milk and cheese.
Use a Cool Compress
Applying a damp, cool washcloth to your forehead can help bring down your temperature.
Take Pain Relievers
Medications such as NOTTS Extra Strength can help reduce fever, alleviate muscle aches, and relieve headaches when used as directed.
When to Seek Medical Attention
If your fever persists, reaches 104°F or higher, or is accompanied by other concerning symptoms like confusion, chest pain, or seizures, seek medical attention immediately.
By staying informed and following these steps, you can effectively manage fever symptoms and support your recovery.
