Minor colds generally do not require medication. If your resistance is normal, adjusting your diet and ensuring proper rest usually allows for natural recovery. In terms of diet, it's important to avoid overly greasy, high-calorie foods, prevent overeating, maintain indoor air cleanliness, drink more ginger tea, avoid staying up late, take your temperature twice daily, and consume fruits and vegetables high in vitamin C, such as kiwi, tomatoes, dragon fruit, and mango. Typically, recovery occurs within three to seven days.
