Waking up with a headache could signal a sleep disorder or another health problem. It's essential to identify triggers such as poor sleep, allergies, or depression.

According to Health, there are seven reasons why you might wake up with a headache.

Sleep apnea

A common cause of morning headaches is sleep apnea, a condition in which you periodically stop breathing during the night.

Then your body wakes you up and you continue to breathe. You may not even realize this is happening. Ask your partner or a friend if you snore loudly, as this is often a sign.

However, remember that snoring does not always mean that you have sleep apnea. However, your doctor may refer you for a sleep study, which is the most accurate way to diagnose sleep apnea.

Insomnia

You've probably heard of insomnia, a common sleep disorder that can cause trouble falling asleep or preventing you from getting a good night's sleep. Headaches are one of the health problems caused by this condition.

Symptoms of insomnia include difficulty falling asleep, staying asleep for a short time, or waking up too early. You may also wake up feeling sleepy and tired during the day.

Teeth grinding

Teeth grinding, also known as bruxism, can cause pain in the jaw muscles or temporomandibular joint (or TMJ, the common name for a jaw disorder that sometimes involves grinding) at night. This pain can lead to headaches.

You may not realize you're grinding your teeth, but watch out for earaches, muscle tenderness, tooth sensitivity, or jaw pain. These are all symptoms of bruxism. A dentist can detect a problem if one exists.

Allergies

Morning headaches can also be caused by allergens. Exposure to dust mites while you sleep (they like to live in your sheets and mattress) can also wake you up with a headache due to the sinus congestion they cause.

If you have allergies, try using allergy-resistant sheets, pillowcases, mattress covers, and special comforters designed to protect you from exposure to dust mites, and wash your sheets more often. Your doctor can help you find additional ways to relieve your symptoms.

Migraine

Although these recurring headaches can occur at any time, migraines are most common in the morning. They often occur on one side of the head, with moderate to severe throbbing or pounding pain.

Other signs that you may have a migraine include nausea, weakness, and sensitivity to light and noise. There are also possible symptoms that can occur up to 24 hours before the headache, such as an aura.

Lack or excessive sleep

Too much or too little sleep can cause tension headaches. They often feel like a bandage is tightening around your head. You may also experience pain or discomfort in your head, scalp, or neck.

Depression and anxiety

Depression and anxiety can also cause morning tension headaches. If you notice headaches that occur during times when you experience or anticipate stress (such as in the morning before work), talk to a healthcare professional to assess whether a mental health condition is the cause.
