Fever has multiple causes like exhaustion, exertion, excessive sports, viral, bacterial, chronic (tuberculosis) or serious infections.
In the case of acute onset, say fever lasting for a day or two: take Paracetamol 650 mg if you are an adult (for children the dose varies based on the body weight, consult your doctor) once in 4-6 hours. If the fever does not subside in 2-3 doses, it is advised to consult a doctor.
