Colds caused by exposure to wind are common, so it's advisable to take some cold medicine or drink herbal teas, such as chrysanthemum tea, to alleviate symptoms. It's important to maintain adequate sleep, avoid excessive stress and overheating. If the cold is severe, it is best to visit a local hospital for symptomatic treatment by a doctor rather than self-medicating blindly. In terms of home environment, it’s recommended to avoid direct exposure to air conditioning or fans. Drinking plenty of lukewarm water and eating nutritious foods, such as lean meats, eggs, beans, and dairy products, can help boost the immune system. It's also wise to consume less spicy and irritating foods.
