Fever is one of the most common reasons people visit a doctor. But not every fever is dangerous, and not every fever needs antibiotics. As a doctor, I often see patients who are worried the moment their temperature rises. In this blog, let’s understand what fever really means, when to worry, and simple steps to take care of your health when you have a fever.
What is Fever?
It is usually caused by viral or bacterial infections, but sometimes by other conditions like heat stroke, dehydration, or autoimmune issues.
A body temperature of 100.4°F (38°C) or above is generally considered a fever.
Common Causes of Fever:
Viral infections like flu, dengue, or COVID-19
Bacterial infections such as urinary tract infection, tonsillitis, or pneumonia
Seasonal illnesses like malaria or chikungunya in certain regions
Non-infectious causes (rare): heat exhaustion, inflammatory conditions
How to Take Care of Yourself at Home:
Rest is essential – Allow your body to recover.
Hydration is key – Drink enough water, coconut water, soups, or ORS.
Light meals – Eat easily digestible foods; avoid oily and heavy meals.
Fever medicines – Paracetamol is safe when taken in the right dose (only after consulting a doctor).
Cool compress – A wet cloth on the forehead can help relieve discomfort.
When to See a Doctor Immediately:
High fever above 102°F (38.9°C) that doesn’t reduce with medicines
Severe headache, stiff neck, rashes, or breathing difficulty
Persistent vomiting, dehydration, or confusion
Fever lasting more than 3 days
Fever in children below 5 years, elderly people, or those with chronic conditions
Prevention Tips for Good Health:
Wash hands regularly and maintain hygiene
Get recommended vaccines (flu, typhoid, etc.)
Eat a balanced diet and exercise regularly to boost immunity
Use mosquito protection during rainy seasons
Regular health checkups, especially if you have diabetes, kidney, or heart issues
