Cold is a common acute whistle blower disease caused mainly by viral infection. Seasonal changes, crowded environment, sedentary lifestyle, advanced age, smoking, poor nutrition, stress, overwork, insomnia and low immunity make people more susceptible to colds. The symptoms of cold are mainly runny nose and sneezing in the early stage, throat discomfort, cough and small amount of phlegm in the later stage, and severe fever. First of all, it is very important to get proper rest and avoid fatigue. Fatigue lowers the body’s immunity and provides an opportunity for viruses to wreak havoc. Rest is the same as giving our bodies time to grow and give them an edge in fighting viruses. People with fever, serious illness and those who are old and weak should be on bed rest. Next, avoid bad habits. Bad habits such as smoking and staying up late can lower immunity, so quitting smoking and good lifestyle habits are also measures to strengthen your resistance. Drink plenty of water and eat light foods properly. Ensuring adequate water intake helps prevent the body from becoming dehydrated. A light and easily digestible diet helps to reduce the burden on the intestinal tract. Medications can reduce the range of symptoms associated with a cold. When symptoms are mild, you can wait for self-recovery. When symptoms are severe, medications can be used to improve them. Since there is a limited selection of antiviral medications available, and considering that most viral infections can be cured on their own, the current treatment is mainly symptomatic and relieves cold symptoms.
