Synopsis of Fever
A fever is a temporary rise in body temperature, usually above 100.4°F (38°C), as part of the body's natural response to infection, inflammation, or other immune triggers. It is regulated by the hypothalamus, which increases the body’s set point in response to signaling molecules called cytokines. Fever is not a disease itself, but a symptom of an underlying issue.
Common causes of fever include:
-
Viral or bacterial infections (e.g., flu, cold, COVID-19, urinary tract infections)
-
Inflammatory conditions (e.g., rheumatoid arthritis)
-
Heat exhaustion or sunstroke
-
Vaccination response
-
Certain medications or reactions (e.g., antibiotics, chemotherapy)
-
Autoimmune or malignant processes in rare cases
Symptoms that may accompany fever include chills, sweating, fatigue, muscle aches, headache, irritability, and loss of appetite. While mild fevers can be beneficial for immune defense, high or prolonged fevers may require attention—especially in infants, the elderly, or immunocompromised individuals.
When to see a doctor:
Seek medical attention if a fever is above 103°F (39.4°C), lasts more than 3 days, is accompanied by confusion, stiff neck, chest pain, rash, difficulty breathing, seizures, or if it occurs in an infant under 3 months old.
Natural remedies for Fever
Stay Hydrated: Fever increases fluid loss; drink water, broth, or electrolyte drinks.
Rest: Conserves energy for immune response and accelerates recovery.
Cool Compress: Apply to forehead, neck, or wrists to provide gentle relief.
Lukewarm Bath or Sponge: Helps regulate temperature without inducing chills.
Light Clothing and Bedding: Avoid heavy blankets unless chills are present.
