What Causes Itchy Throat: Common Triggers

An itchy throat can be caused by many things, like allergies or environmental irritants. Knowing what causes it helps find the right treatment.

Allergic Rhinitis and Hay Fever

Allergic rhinitis, or hay fever, is a big reason for an itchy throat. It happens when the body reacts too much to things like pollen or pet dander. Between 40 to 60 million Americans are affected by allergic rhinitis.

Symptoms include not just an itchy throat but also sneezing and itchy eyes. To deal with it, avoid things that trigger it. For example, stay inside with windows closed during pollen season. Over-the-counter antihistamines and nasal sprays can also help.

Viral and Bacterial Infections

Viral and bacterial infections also cause an itchy throat. Viral infections account for 85 to 95 percent of adult sore throats. The common cold and flu are common culprits. Bacterial infections, like strep throat, make up the rest.

It’s important to tell the difference between viral and bacterial infections. Viral infections usually get better on their own, but bacterial ones might need antibiotic therapy. A doctor can figure out what it is with a throat swab or other tests.

Dehydration and Environmental Irritants

Dehydration often leads to an itchy throat, more so in hot weather or after working out. When we lose more water than we drink, our throat gets dry. Drinking plenty of water helps a lot. Things like cigarette smoke and pollution can also make our throat itch.

To avoid dehydration, drink water all day. Using a humidifier in dry places helps keep our throat moist. Staying away from irritants and wearing a mask can also help.
