For symptoms of a cold and headache, if you have a fever, you can choose to use ice packs or a cool towel for local cold compresses. You can also use warm water to apply heat to the palms, soles, neck, and chest. This can dilate capillaries and relax sweat glands, promoting sweating and helping to restore normal body temperature. Additionally, you should adjust your diet, avoid stimulating, spicy, and overly greasy foods, and eat more foods that are high in rough fiber and vitamins.
