Hi. .   . Rest. Get plenty of sleep and rest your voice. Drink fluids. Drink plenty of water to keep the throat moist and prevent dehydration. Try comforting foods and beverage. Warm liquids — broth, caffeine-free tea or warm water with honey — and cold treats such as ice pops can soothe a sore throat. Gargle saltwater. A saltwater gargle of 1 teaspoon. Gargle the solution and then spit it out.
