Consider it a gastrointestinal cold. To prevent and treat the common cold, it’s important to maintain a strong physique and adopt certain nourishing methods. Normally, try to drink ginger tea, using fresh ginger and a moderate amount of brown sugar to boil water for tea, which can effectively prevent and treat the common cold, helping to enhance the body’s resistance to illness. Each night, soak your feet for 15 minutes, ensuring the water covers the feet, and after soaking, your feet should turn red, which can also prevent colds. Additionally, it’s important to exercise regularly and keep the bedroom well-ventilated.
