There is no “best” way to treat a cold with low-grade fever. The symptoms can be relieved by general treatment. Colds are viral infections that are self-limiting and can usually be cured in about 1 week. During the period of illness, patients should pay attention to keep a light diet, drink more water, and avoid eating spicy and greasy food. Avoid staying up late, regular work and rest, ensure adequate sleep, and enhance the body’s immunity. For symptoms of low fever, you can choose to use towels to wipe the body, apply ice and other methods to physically cool down the temperature. If the patient’s symptoms worsen or other discomforts occur, he should seek medical treatment as soon as possible and receive regular treatment.
