Drink some light porridge during a cold, such as vegetable porridge or rice porridge, because at this time, the body's resistance drops, and you can't eat some foods that are too spicy, irritating and greasy, which will lead to nausea, vomiting, abdominal pain and bloating.

We should also strengthen nutrition and eat more foods rich in protein, such as beef, milk, lean meat and eggs. Drink more warm water, eat more fresh fruits and vegetables, keep warm and avoid catching a cold. If there are symptoms such as fever, headache, cough and yellow sputum due to bacterial infection, active anti-inflammatory and anti-infection treatment should be taken according to the drug sensitivity results of sputum culture.
