During a cold, it is advisable to eat some liquid foods appropriately. If it is a cold caused by wind-cold, at this time, you can appropriately drink some brown sugar ginger water, which can expel the coldness in the body and alleviate some symptoms of the wind-cold cold. If it is a wind-heat cold, then you can drink some rock sugar pear water or Fritillaria pear water at this time, which has the effects of clearing heat and detoxifying, reducing fire, moisturizing the lungs, and relieving cough. At the same time, it is recommended that everyone must pay attention to getting more rest during a cold, not to overwork, eat more fresh fruits and vegetables, supplement vitamins, and increase their resistance. Additionally, it is also appropriate to drink some millet juice or vegetable juice, and yam juice, etc., which can supplement the body's vitamins and meet the body's needs for vitamins.
