Why Does My Throat Hurt at Night?
Sore throat at night is a common complaint that many people experience. A sore throat is generally caused by inflammation of the pharynx (the part of the throat that is located behind the mouth and nasal cavity). The pharynx is responsible for transmitting food and air to the esophagus and trachea, respectively. A sore throat at night can be caused by several factors such as acid reflux, postnasal drip, dry air, and sleeping with your mouth open. In this article, we will discuss the anatomy of the throat, common causes of nighttime throat pain, less common causes of nighttime throat pain, when to see a doctor, and tips for preventing nighttime throat pain.
Anatomy of the Throat
The throat is made up of several structures, including the pharynx, larynx, tonsils, and epiglottis. The pharynx is divided into three sections: the nasopharynx, oropharynx, and laryngopharynx. The nasopharynx is located behind the nasal cavity and is responsible for transmitting air to the lungs. The oropharynx is located behind the mouth and is responsible for transmitting food to the esophagus. The laryngopharynx is located at the bottom of the pharynx and is responsible for transmitting both food and air.
The tonsils are located in the oropharynx and play an important role in the immune system. They are responsible for filtering out harmful bacteria and viruses that enter the body through the mouth and nose. The epiglottis is located at the top of the larynx and prevents food and liquid from entering the trachea during swallowing.
Common Causes of Nighttime Throat Pain
Acid reflux: Acid reflux occurs when stomach acid flows back into the esophagus. This can cause irritation and inflammation of the esophagus and throat, leading to a sore throat. Acid reflux is more common at night because when you lie down, the acid in your stomach is more likely to flow back up into your esophagus.
Postnasal drip: Postnasal drip occurs when excess mucus drains from the back of the nose into the throat. This can cause irritation and inflammation of the throat, leading to a sore throat. Postnasal drip is more common at night because when you lie down, the mucus in your nose is more likely to flow down into your throat.
Dry air: Dry air can irritate the throat and cause it to become dry and scratchy. This can lead to a sore throat. Dry air is more common at night because the air in your bedroom is typically drier than the air during the day.
Sleeping with your mouth open: Sleeping with your mouth open can cause your throat to become dry and irritated. This can lead to a sore throat. When you breathe through your mouth, the air is not humidified as it is when you breathe through your nose.
Less Common Causes of Nighttime Throat Pain
Allergies: Allergies can cause inflammation of the throat, leading to a sore throat. Allergies can be caused by a variety of factors such as pollen, dust, mold, and pet dander.
Infections: Infections such as strep throat and tonsillitis can cause inflammation of the throat, leading to a sore throat. These infections are caused by bacteria and are typically accompanied by other symptoms such as fever and swollen lymph nodes.
Injuries: Injuries to the throat such as burns, cuts, and abrasions can cause inflammation and pain. These injuries can be caused by hot liquids, swallowing sharp objects, or trauma to the neck.
Gastroesophageal reflux disease (GERD): GERD is a chronic condition that occurs when the lower esophageal sphincter (LES) fails to close properly, causing stomach acid to flow back into the esophagus. This can cause irritation and inflammation of the esophagus and throat, leading to a sore throat. GERD is more common at night because when you lie down, the acid in your stomach is more likely to flow back up into your esophagus.
When to See a Doctor
While most cases of nighttime throat pain are not serious and can be treated at home, there are some situations where you should see a doctor. You should see a doctor if:
- Your throat pain lasts for more than a week
- You have difficulty swallowing
- You have a fever
- You have swollen lymph nodes in your neck
- You have a rash
- You have difficulty breathing
If you have any of these symptoms, you should see a doctor as soon as possible. Your doctor will perform a physical examination and may order additional tests such as a throat culture, blood tests, or imaging tests.
