. If you smoke, you should make an effort to quit. Smoking is bad for your overall health. It can make you more susceptible to throat infections such as bronchitis and strep  throat. It can also cause overall damage to the throat and vocal cords, resulting in discomfort and congestion. Talk to your doctor about quitting smoking. Smoking also predisposes a person to carcinogens which can lead cancer. Oftentimes, a dry environment can result in throat irritation. Consider purchasing a humidifier if you live in a dry area. Turning a humidifier on during the day or overnight can increase moisture in your home, reducing throat irritation. If you're prone to frequent throat irritation, evaluate how you speak. Straining your voice can cause a sore throat, resulting in the build up of phlegm.  If you have throat irritation, try to avoid coughing. Too much coughing can actually make an infection worse. If necessary, take over-the-counter cough suppressants or lozenges to ease irritation that leads to coughing.  Avoid screaming, shouting, or cheering. If you work in a field that requires you to talk loudly, make an effort to rest your voice at the end of the day. Speak softly and try not to raise your voice. Coughing, wheezing, and otherwise attempting to clear your throat can sometimes provide momentary relief. However, if you engage in these behaviors too frequently when you have a sore throat this can cause irritation. This could potentially increase the duration of symptoms. If you feel tempted to clear your throat, consider purchasing over-the-counter cough drops or lozenges at the drugstore to provide some relief. Alcohol and caffeine can both increase dehydration, leading to a dry and irritated throat. Try to avoid drinking caffeinated beverages or alcohol in excess. For men, limit your alcohol intake to two drinks a night. For women, try to stay around one drink. A sore or congested throat is not usually a medical concern and should clear up on its own. However, if you remain congested for more than two weeks see your doctor to rule out an underlying medical condition. Keep in mind that a sore throat and congestion are two separate symptoms that can result in worsening of each individual symptom. Congestion refers to nasal areas and sinus swelling increasing stuffy sensation, while a sore throat refers to pain in the throat. Post nasal drip and cough can worsen sore throats.

Summary:
Quit smoking Invest in a humidifier. Avoid straining your voice. Do not clear your throat too often. Avoid alcohol and caffeine. Seek medical help.
