About the topic
A fever is commonly a temperature of 38°C or above. How unwell you feel and whether symptoms are worsening also matter.
Practical care & comfort
- Rest and drink fluids regularly, unless a clinician has restricted your intake.
- Avoid close contact with others while you have a fever.
- Ask a clinician or pharmacist before choosing medicines, especially if you have other conditions.
Symptoms & signs
- A temperature of about 38°C or higher.
- Feeling hot, cold or shivery, sometimes even below that reading.
- Sweating or a chest and back that feel hotter than usual.
When to speak with a clinician: Seek prompt advice if home care is not helping, the fever worsens, or you are concerned.
Food & nutrition
Hydration is supportive care. Get urgent advice if fever worsens, you cannot keep fluids down or you pass very little urine.
Foods & nutrition to follow
- Drink water regularly, unless your clinician has restricted fluids.
- Use small sips if nausea makes drinking difficult.
Foods to limit or avoid
- Avoid alcohol while you are at risk of dehydration.
- Avoid caffeinated drinks if you are dehydrated.
