🌿 Overview
A fever is the body's way of fighting infection by running warmer than usual. A mild fever is often helpful, so the aim is comfort and fluids rather than erasing it. Rest, cool compresses, and plenty to drink carry most people through — while very high or lasting fevers, and any fever in the very young or very old, call for a doctor.
A fever is when the body runs warmer than normal — usually above about 100°F (38°C). It is not a sickness by itself, but a sign that the body is fighting something, most often an infection like a cold or the flu. Think of it as the body turning up the heat on purpose: a slightly warm body helps the immune systemYour body's built-in defense team that fights off germs and helps you heal. More →, the body's defense team, work faster and makes it harder for germs to thrive. Because a mild fever is part of healing, the goal usually isn't to erase it but to keep the person comfortable and well-hydrated while it does its job. Rest, cool cloths, and plenty of fluids carry most people through. A fever that is very high, lasts several days, or comes with worrying signs is different — that's when it's time to call a doctor. Fever needs more care in babies, young children, and older adults, whose bodies handle big temperature swings less easily. When in doubt with the very young or very old, it's always wise to check with a professional.

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Plenty of cool water and clear fluids
- Warm vegetable **broths** and simple soups
- Vitamin-C-rich fruits like citrus and berries
- Light, easy foods once appetite returns
Go easy on
- Heavy, greasy, or fried foods while you have no appetite
- Sugary drinks and alcohol, which work against hydration
- Forcing solid food during a high fever — fluids matter more
While a fever is high, lean on fluids; add gentle, light food back as the fever eases and hunger returns.
⚖️ Good to know
- A fever is a symptom, not a disease — the underlying cause still needs care.
- Take extra care with fevers in babies, young children, and older adults.
- Don't bundle a feverish person in heavy blankets — it can trap heat.
- Use lukewarm, not cold, water to cool the body; cold can cause shivering that raises the temperature.
🩺 When to see a doctor
- Any fever in a baby under 3 months
- A fever above 103°F (39.4°C) in adults, or that won't come down
- A fever lasting more than about three days
- Stiff neck, severe headache, confusion, or trouble waking
- Trouble breathing, chest pain, or a rash that doesn't fade when pressed
- Seizure, or a child who is very drowsy, limp, or hard to rouse
