What is the reason behind swallowing often during a sore throat?

There are a few reasons why people swallow often during a sore throat:

1. To clear away mucus and debris: Swallowing can help to clear away mucus and debris that has accumulated in the back of the throat. This can help to reduce irritation and make swallowing easier.

2. To lubricate the throat: Swallowing can help to lubricate the throat and make it easier to swallow. This is especially important when the throat is dry and irritated.

3. To reduce pain: Swallowing can help to numb the pain of a sore throat. This is because swallowing causes the muscles in the throat to contract, which can release endorphins. Endorphins are natural painkillers that can help to reduce the pain of a sore throat.

4. To avoid coughing: Swallowing can help to avoid coughing, which can further irritate a sore throat.

5. To protect the lungs: Swallowing can help to protect the lungs from any bacteria or viruses that may be present in the throat.
