Drink Ice cold carbonated water.
Can improve swallowing ability
In one study, 16 healthy people were asked to repeatedly swallow different liquids. Carbonated water showed the strongest ability to stimulate the nerves responsible for swallowing (9Trusted Source).
Another study showed that the combination of cold temperature and carbonation strengthened these beneficial effects (10Trusted Source).
In a study in 72 people who felt a persistent need to clear their throats, drinking ice-cold carbonated water led to improvements in 63% of participants. Those with the most frequent, severe symptoms experienced the greatest relief (11Trusted Source).
