Do you wake up tired even after spending enough time in bed? Do you snore loudly or wake up with a dry mouth or headache?

Sometimes these problems are simply related to poor sleep habits. But they can also be signs of sleep apnea, a sleep disorder in which breathing repeatedly becomes interrupted during sleep.

Sleep problems are common in the United States. CDC data show that 30.5% of U.S. adults slept fewer than 7 hours per night on average in 2024.

Sleep apnea is different from simply not getting enough sleep, and persistent symptoms deserve medical attention.

What Is Sleep Apnea?

Sleep apnea is a condition in which normal breathing is repeatedly disrupted during sleep.

One common form is obstructive sleep apnea (OSA). It occurs when the upper airway becomes blocked or narrowed during sleep.

Because these breathing disruptions happen while you're asleep, you may not realize they are occurring.

A sleep partner or family member may notice symptoms before you do.

1. Loud, Frequent Snoring

Snoring is one of the best-known signs associated with obstructive sleep apnea.

However, not everyone who snores has sleep apnea, and not everyone with sleep apnea necessarily snores loudly.

If your snoring is persistent or unusually loud, especially when accompanied by other symptoms, discuss it with a healthcare professional.

2. Gasping or Choking During Sleep

Some people with sleep apnea may wake briefly after breathing becomes interrupted.

A sleeping partner might notice:

• Gasping
• Choking sounds
• Pauses in breathing
• Sudden changes in breathing patterns

You may not remember these episodes the next morning.

If someone regularly notices these signs while you're sleeping, tell a healthcare professional.

3. Feeling Extremely Tired During the Day

Repeated breathing disruptions can interfere with normal sleep.

As a result, someone with sleep apnea may experience:

• Daytime sleepiness
• Fatigue
• Difficulty staying alert
• Feeling unrefreshed after sleep

These symptoms can overlap with many other conditions, so they don't automatically mean you have sleep apnea.

4. Morning Headaches

Some people with sleep apnea report waking with headaches.

Morning headaches can have many possible causes, however, so this symptom alone isn't enough to diagnose sleep apnea.

If morning headaches happen regularly alongside loud snoring, gasping or daytime sleepiness, consider discussing the combination with a healthcare professional.

5. Difficulty Concentrating

Poor-quality sleep can affect daytime alertness and concentration.

You might notice that you're having more difficulty:

• Focusing on tasks
• Remembering things
• Staying alert
• Completing everyday activities

Persistent concentration problems should be evaluated rather than automatically attributed to poor sleep.

6. Dry Mouth or Sore Throat in the Morning

Some people wake with a dry mouth or sore throat.

Mouth breathing during sleep can contribute to dryness, although there are many other possible causes.

If morning dry mouth occurs together with loud snoring or other sleep-apnea symptoms, mention it during a medical evaluation.

7. Waking Up Frequently During the Night

Repeated nighttime awakenings can interfere with restorative sleep.

Some people may wake without knowing why, while others may notice gasping, choking or difficulty breathing.

Frequent nighttime waking can have many causes, including insomnia, stress, medications and other sleep disorders, so professional evaluation may be helpful if it persists.

Who Is More Likely to Develop Sleep Apnea?

Sleep apnea can affect people with different body types and backgrounds.

Risk can be influenced by factors including:

• Age
• Family history
• Certain anatomical features
• Obesity
• Some medical conditions
• Alcohol use
• Certain medications

Having a risk factor does not mean you definitely have sleep apnea.

How Is Sleep Apnea Diagnosed?

A healthcare professional will usually review your symptoms and medical history.

If sleep apnea is suspected, a sleep study may be recommended.

Depending on the person's situation, testing can involve an overnight study in a sleep center or a home sleep apnea test.

The American Academy of Sleep Medicine recommends appropriate diagnostic testing for adults suspected of having obstructive sleep apnea.

A home test isn't appropriate for everyone, so testing should be selected by a qualified healthcare professional.

Can Sleep Apnea Be Treated?

Yes. Sleep apnea can be treated, but the appropriate treatment depends on the type and severity of the condition.

Treatment may involve options such as:

• Positive airway pressure therapy
• Oral appliances for selected patients
• Lifestyle changes
• Positional approaches in appropriate cases
• Other medical treatments when indicated

A healthcare professional can determine which option is appropriate.

You should not attempt to diagnose or treat sleep apnea solely from an online symptom checklist.

When Should You See a Doctor?

Consider talking with a healthcare professional if you regularly:

• Snore loudly
• Wake up gasping or choking
• Feel excessively sleepy during the day
• Wake with frequent headaches
• Have repeated nighttime awakenings
• Feel unrefreshed despite getting enough time in bed

If a partner tells you that your breathing repeatedly stops during sleep, that is particularly important to mention to a healthcare professional.

Frequently Asked Questions

Is loud snoring always sleep apnea?

No. Snoring can occur without sleep apnea. However, loud persistent snoring combined with gasping, breathing pauses or daytime sleepiness can warrant evaluation.

Can you have sleep apnea without snoring?

Yes. Snoring is common but isn't required for sleep apnea to occur.

Why am I tired even after sleeping for 8 hours?

There are many possible reasons, including poor sleep quality, an inconsistent sleep schedule, stress, medications and sleep disorders such as sleep apnea.

Can sleep apnea go away on its own?

Sleep apnea shouldn't be assumed to disappear without evaluation. The appropriate treatment depends on the cause and type of sleep apnea.

Is sleep apnea dangerous?

Untreated sleep apnea can be associated with significant health problems. If you suspect you have it, speak with a healthcare professional rather than trying to diagnose yourself.

How is sleep apnea tested?

A healthcare professional may recommend a sleep study. Depending on the situation, this can involve a sleep-center study or an appropriate home sleep apnea test.

Final Thoughts

Occasional snoring or tiredness doesn't necessarily mean you have sleep apnea. But persistent loud snoring, gasping during sleep, daytime sleepiness and repeated nighttime awakenings shouldn't simply be ignored.

If these symptoms are happening regularly, talk with a qualified healthcare professional. Proper testing can determine whether sleep apnea or another sleep disorder is responsible.
