Vaping involves inhaling an aerosol created by heating a liquid. Vaping can indeed cause a sore throat, a common concern for many users. This discomfort often arises from specific mechanisms involved in vapor production and the chemical composition of e-liquids. This article explores how vaping affects the throat, examines the roles of e-liquid ingredients, and offers advice for relief, alongside guidance on when to seek medical attention.
How Vaping Irritates the Throat
Vaping can irritate the throat through several physical mechanisms. Inhaling warm vapor directly affects the sensitive mucous membranes lining the throat, leading to a drying effect and a scratchy or sore sensation. The heat of the vapor itself also acts as a direct irritant to these delicate tissues.
The physical sensation experienced during vaping, often referred to as “throat hit,” can also contribute to discomfort. This sensation is essentially a mild irritation in the back of the throat. In some instances, issues with the vaping device, such as a “dry hit” where the coil burns dry cotton due to insufficient e-liquid, can produce a harsh vapor that severely irritates the throat.
Vape Liquid Components and Throat Discomfort
The ingredients within vape liquids contribute to throat irritation. Propylene Glycol (PG) and Vegetable Glycerin (VG) are base ingredients, with PG being a common cause of dryness and irritation. PG is hygroscopic, meaning it absorbs water from the mouth and throat, leading to dehydration and a scratchy feeling. Some individuals can also have a sensitivity or allergic reaction to PG, which can manifest as a sore throat, coughing, or even skin irritation.
Vegetable Glycerin (VG), while also hygroscopic, is smoother and less irritating than PG, producing a denser vapor. However, even VG can cause throat irritation and dryness, particularly with frequent use or if the body is not adequately hydrated. The ratio of PG to VG in e-liquids plays a role in the intensity of throat discomfort.
Nicotine concentration also influences throat irritation; higher nicotine levels produce a stronger, harsher “throat hit.” This is more noticeable with freebase nicotine, while nicotine salts provide a smoother sensation even at higher concentrations. Certain flavorings in e-liquids can also act as irritants. Some fruit and citrus flavors, for instance, are known to contribute to throat irritation.
Relieving Vaping-Related Throat Soreness
Several steps can help alleviate vaping-related throat soreness. Increasing daily water intake is important, as both PG and VG draw moisture from the mouth and throat, leading to dehydration. Staying well-hydrated keeps mucous membranes moist and reduces irritation.
Adjusting vape device settings can also provide relief. Lowering the wattage or temperature produces a cooler, less harsh vapor, gentler on the throat. Choosing e-liquids with a higher Vegetable Glycerin (VG) content and lower Propylene Glycol (PG) can significantly reduce irritation, as VG is known for a smoother vape. Trying a lower nicotine strength or switching to nicotine salt e-liquids can also decrease the harshness. Taking breaks from vaping allows the throat time to recover.
When to Consult a Doctor About Throat Symptoms
While vaping can cause temporary throat irritation, certain symptoms indicate a need for medical consultation. If throat pain persists or worsens over several days despite relief measures, seek medical advice. Symptoms like difficulty swallowing, fever, or swollen glands accompanying a sore throat could signal a more serious underlying condition.
Individuals experiencing persistent coughing, hoarseness, or worsening asthma symptoms related to vaping should consult a healthcare provider. If there are signs of an allergic reaction beyond typical throat irritation, such as rashes, widespread swelling, or significant breathing difficulties, immediate medical attention is needed. A doctor can help determine if the symptoms are solely related to vaping or if another health issue is present.
