Drink Water to Stay Hydrated
Having a dry cough means that your throat is dry, and it must be understood that during a dry cough your body requires more water intake. Hence it is advised to drink eight 8-oz. glasses of warm water daily for the betterment of health.
If you rub Eucalyptus oil on your throat as well as the chest area after regular intervals, it will make the mucous membranes open, thus allowing the passage of mucous, water and other fluids which will lubricate the sore dry throat.
Breathe Humidified Air
While having a sore throat, particularly in winter, if you are sitting in a warm room, it may often lead to irritation of the airway that will make a dry cough even worse. Therefore, it is recommended to have a humidifier in your room to add moisture in the air you are inhaling.
A dry throat will make you feel pain while you cough. For this reason, you should try to keep it lubricated as much as possible. In order to do so, you must try to have a hot cup of tea with honey. Having chicken or hot vegetable soup also keeps your throat lubricated.
