(HealthDay News) -- Laryngitis, an inflammation of the larynx, makes a person's voice hoarse. It's typically caused by a viral infection, and can be exacerbated by smoking.

Smokers should quit while waiting for laryngitis to improve, the National Library of Medicine (NLM) says.

Because it's typically caused by a virus, common laryngitis often doesn't require treatment with antibiotics. Call your doctor if the condition is accompanied by difficulty breathing or swallowing.

Laryngitis typically will clear up on its own, but you can use a humidifier to ease throat irritation and hoarseness.

Resting your vocal cords can help restore your voice more quickly, the NLM says.
