What Are the Common Causes of a Sore Throat?
A sore Throat is most often caused by viral infections, such as the common cold, flu, or other upper respiratory viruses. These infections can lead to inflammation of the throat tissues, causing pain, dryness, or a scratchy feeling, especially when swallowing. Seasonal allergies are another common cause, as pollen, dust, or pet dander can trigger postnasal drip that irritates the throat over time. Environmental factors also play a role, including dry air, cold weather, or spending long periods in air-conditioned or heated spaces, which can dry out and irritate the throat lining.
Bacterial infections, such as Strep Throat, may also cause a sore throat, though they are less common than viral causes. Other contributors include acid reflux, where stomach acid travels upward and irritates the throat, as well as voice strain from excessive talking or shouting. Exposure to smoke, pollution, or other irritants can further increase throat discomfort. Fortunately, most sore throats are mild and temporary, and understanding the cause helps support timely care, comfort, and a smooth recovery.
