To control early signs of a cold, first and foremost pay attention to adjusting your lifestyle and diet. Avoid staying up late and overworking, opt for bland, soft, and easily digestible foods, abstain from smoking and alcohol, and avoid eating meat. Consume more fruits and vegetables that are rich in vitamins, ensure sufficient and good quality sleep, and drink more ginger sugar water or scallion white broth. These can warm the body and disperse cold, aiding in the recovery from a cold. Additionally, measure your temperature twice daily to check for any signs of fever, and treat the symptoms accordingly.
