My family probably thinks I’m nuts. Every time someone gets sick in my family, I tell them to drink lots of ginger ale.
I’ve found that ginger ale will settle an upset stomach quickly, so it is a great cure for nausea. And it is easier on the stomach than plain water, so it is a great beverage to drink to prevent dehydration. It has a little bit of sodium and sugar, so it helps to keep the body nourished when it might otherwise be suffering from little food intake.
When I’m sick, I drink room-temperature ginger ale. I find that cold beverages are harder on the stomach and sinuses, so I try to avoid drinking anything cold.
