Waking Up Tired? Why Sleep Apnea Occurs & Medical Next Steps

If you regularly wake up feeling exhausted—even after what should have been a full night's sleep—sleep apnea could be the reason. Many people assume they're simply stressed, overworked, or "bad sleepers." But when sleep doesn't restore your energy, your body may be struggling to breathe properly at night.

Sleep apnea is common, underdiagnosed, and treatable. Understanding why it happens and what to do next can significantly improve your health, mood, and long-term wellbeing.

What Is Sleep Apnea?

Sleep apnea is a medical condition where breathing repeatedly stops and starts during sleep. These pauses can last from a few seconds to over a minute and may happen dozens or even hundreds of times per night.

Each time breathing stops, oxygen levels drop. Your brain senses this and briefly wakes you up—often without you remembering—to restart breathing. These constant interruptions prevent deep, restorative sleep.

There are three main types of sleep apnea:

• Obstructive Sleep Apnea (OSA): The most common type. It occurs when throat muscles relax and block the airway.
• Central Sleep Apnea: The brain doesn't send proper signals to control breathing.
• Complex Sleep Apnea Syndrome: A combination of obstructive and central sleep apnea.

Most people with sleep apnea have the obstructive type.

Why Does Sleep Apnea Occur?

Sleep apnea usually develops due to a combination of physical and neurological factors.

1. Airway Blockage (Most Common Cause)

In obstructive sleep apnea, the airway collapses or becomes blocked during sleep. Contributing factors include:

• Excess weight, especially around the neck
• Enlarged tonsils
• A naturally narrow airway
• Relaxed throat muscles during sleep
• Large tongue or soft palate
• Sleeping on your back

When these structures narrow the airway, airflow decreases or stops entirely.

2. Brain Signaling Problems

In central sleep apnea, the issue is not a blocked airway. Instead, the brain temporarily fails to send proper signals to the muscles that control breathing. This can be linked to:

• Heart failure
• Stroke
• Certain neurological conditions
• Use of opioid medications

3. Risk Factors That Increase Likelihood

Sleep apnea can affect anyone, but risk increases with:

• Being overweight or obese
• Male sex (though women are affected too)
• Age over 40
• Family history of sleep apnea
• Smoking
• Alcohol use, especially before bed
• High blood pressure
• Type 2 diabetes

Even children can develop sleep apnea, often due to enlarged tonsils or obesity.

Common Signs and Symptoms of Sleep Apnea

Many people don't realize they have sleep apnea because symptoms occur during sleep. Often, a partner notices first.

Nighttime Symptoms

• Loud, chronic snoring
• Gasping or choking during sleep
• Pauses in breathing witnessed by another person
• Restless sleep
• Frequent waking

Daytime Symptoms

• Waking up tired, even after 7–8 hours
• Morning headaches
• Dry mouth upon waking
• Difficulty concentrating
• Irritability or mood changes
• Falling asleep during the day
• Reduced work performance

Excessive daytime sleepiness is not just inconvenient—it can increase the risk of car accidents and workplace injuries.

Why Sleep Apnea Should Be Taken Seriously

It's important not to ignore persistent symptoms. Untreated sleep apnea can increase the risk of serious health problems over time.

Potential complications include:

• High blood pressure
• Heart disease
• Heart rhythm problems (arrhythmias)
• Stroke
• Type 2 diabetes
• Depression
• Memory issues
• Complications after surgery

This does not mean that everyone with sleep apnea will develop these conditions. But untreated, moderate to severe sleep apnea significantly raises long-term risk.

The good news: effective treatment can reduce these risks.

What to Do If You Suspect Sleep Apnea

If you often wake up exhausted, snore loudly, or feel sleepy during the day, taking action is important.

Step 1: Assess Your Symptoms

Before scheduling a doctor's appointment, you can quickly evaluate your symptoms using Ubie's free AI-powered Sleep Apnea Syndrome symptom checker to see if your symptoms match common sleep apnea patterns and understand what to discuss with your healthcare provider.

This is not a diagnosis—but it can guide your next steps.

Step 2: Speak to a Doctor

If symptoms suggest sleep apnea, make an appointment with a healthcare provider. Be prepared to discuss:

• Your sleep patterns
• Snoring severity
• Daytime sleepiness
• Medical history
• Medications you take

If anything feels severe—such as extreme daytime sleepiness, chest pain, or shortness of breath—seek medical care promptly.

How Sleep Apnea Is Diagnosed

Doctors typically confirm sleep apnea with a sleep study.

1. Polysomnography (Sleep Lab Study)

This overnight test measures:

• Breathing patterns
• Oxygen levels
• Heart rate
• Brain activity
• Body movements

It provides the most comprehensive information.

2. Home Sleep Apnea Testing

In some cases, doctors may recommend a simplified test done at home. It monitors breathing and oxygen levels but collects less data than a lab study.

Results are reported as the Apnea-Hypopnea Index (AHI):

• Mild: 5–14 events per hour
• Moderate: 15–29 events per hour
• Severe: 30+ events per hour

This number helps guide treatment decisions.

Treatment Options for Sleep Apnea

Treatment depends on severity and individual factors. Many options are effective and manageable.

1. CPAP Therapy (Most Common Treatment)

Continuous Positive Airway Pressure (CPAP) machines deliver air pressure through a mask to keep the airway open.

Benefits:

• Reduces snoring
• Improves daytime energy
• Lowers blood pressure
• Reduces cardiovascular risk

It may take time to adjust, but modern machines are quieter and more comfortable than older versions.

2. Oral Appliances

Custom-fitted mouthpieces can reposition the jaw to keep the airway open. These are often used for mild to moderate sleep apnea.

3. Lifestyle Changes

For some individuals, lifestyle adjustments significantly reduce symptoms:

• Weight loss
• Regular exercise
• Avoiding alcohol before bedtime
• Sleeping on your side
• Quitting smoking

Even modest weight loss can reduce severity in overweight individuals.

4. Surgery

In certain cases—such as enlarged tonsils or structural airway issues—surgery may be considered.

Can Sleep Apnea Be Cured?

In some cases, especially when caused by weight gain or enlarged tonsils, sleep apnea can improve or resolve. However, many people manage it as a long-term condition.

The key is ongoing treatment and follow-up care.

---

When to Seek Immediate Medical Attention

While sleep apnea itself develops gradually, certain symptoms require urgent evaluation:

• Chest pain
• Severe shortness of breath
• Sudden confusion
• Stroke-like symptoms
• Falling asleep while driving

If you experience any of these, seek emergency medical care immediately.

The Bottom Line

Waking up tired every day is not normal—and it's not something you should ignore. Sleep apnea is common, treatable, and often life-changing once addressed.

If you:

• Snore loudly
• Feel exhausted despite sleeping
• Wake up with headaches
• Struggle with concentration
• Or have been told you stop breathing at night

Take the next step.

Start by completing a free online Sleep Apnea Syndrome symptom checker, then speak to a doctor about your symptoms. Proper diagnosis and treatment can dramatically improve your sleep, energy, and long-term health.

Sleep should restore you. If it doesn't, it's time to find out why.
