Alternating warm and cold liquids
Hot and cold temperatures have each a different effect on your body. On cold temperatures, you get a numbing sensation that significantly improves pain. On hot temperatures, you stimulate the circulation of your blood and allow your body to fight more efficiently against pathogens. Thus, it is a very good idea to alternate between warm and cold liquids.
Eating a sorbet is not only tasty but will also reduce the symptoms by making food a bit easier to swallow. It has a numbing effect that will stay with you for a while, but if you go out for ice cream, it is better to avoid adding seasoning that may scratch your mucosa and contribute to your sore throat.
On the other hand, your daily coffee routine is also a good thing to keep. Drinking warm liquids, including herbal infusions and tea, will provide a sense of relief and improve the drainage of mucus and other fluids in your respiratory system.
