You wake up tired—even after a full night in bed. Your partner says you snore loudly or stop breathing for seconds at a time. You feel foggy, irritable, and your blood pressure’s been creeping up.
It might seem like just bad sleep. But what if it’s your heart that’s being silently stressed every night?
Many adults in Dubai, Abu Dhabi, and Al Ain don’t realize that sleep disorders—especially obstructive sleep apnea—can have serious effects on heart health. And the connection isn’t just indirect: untreated sleep issues can directly increase your risk for high blood pressure, arrhythmias, heart attacks, and stroke.
At KidsHeart’s Adult Cardiology department, we work with patients every week whose heart concerns turn out to be linked with breathing disturbances during sleep.
What Is Sleep Apnea—and Why Does It Affect the Heart?
Obstructive sleep apnea (OSA) is a common but underdiagnosed condition where your airway becomes partially or fully blocked during sleep. This causes:
- Loud snoring or choking sounds
- Gasping for air
- Interrupted breathing (often noticed by a partner)
- Frequent nighttime awakenings
- Morning headaches and dry mouth
Each time breathing stops, your oxygen levels drop and your body experiences a mini stress response—raising your heart rate and blood pressure. Over time, this repeated strain contributes to hypertension, heart rhythm issues, and even heart failure.
How Common Is It?
In the UAE, research shows that up to 30–40% of middle-aged men and 20–25% of women may have some degree of sleep apnea—often without knowing it. The rates are even higher in people who:
- Are overweight or have a large neck circumference
- Have high blood pressure or diabetes
- Experience daytime fatigue or snoring
- Have a family history of apnea or stroke
Yet most adults don’t get screened until a serious cardiac issue brings them to a specialist.
How Sleep Impacts Heart Function—Silently
Poor sleep affects your cardiovascular system in several hidden ways:
- High Blood Pressure (Hypertension)
Each episode of apnea spikes your blood pressure—eventually making it chronically elevated. Even in young adults, this creates long-term heart damage.

- Irregular Heart Rhythms (Arrhythmias)
Sleep apnea is closely linked with atrial fibrillation (AFib)—a common arrhythmia that increases stroke risk.
We offer full Palpitations and Arrhythmia Workups if you’re experiencing fluttering or skipping heartbeats.
- Low Oxygen to the Heart
Frequent oxygen dips reduce the blood supply to your heart muscle. In people with existing coronary artery disease, this can trigger chest pain or heart attacks overnight.
- Increased Risk of Stroke
Untreated apnea doubles your risk of stroke—particularly concerning for adults with other risk factors like diabetes or smoking.
Signs You Should Be Evaluated
Consider a cardiopulmonary evaluation if you:
- Snore loudly or have been told you stop breathing in sleep
- Feel exhausted during the day despite 7–8 hours of sleep
- Have high blood pressure that’s hard to control
- Wake up gasping or with a dry mouth
- Have frequent morning headaches or mood swings
- Already have heart disease, AFib, or a recent stroke
Our Cardio-Pulmonary Care services bridge heart and lung evaluations—ensuring your sleep issues don’t go unnoticed.
UAE Lifestyle Factors That Add to the Problem
In cities like Abu Dhabi and Dubai, several environmental and lifestyle factors increase the risk of sleep-related cardiac problems:
- Heavy meal timing and late-night work hours
- Use of screens before bed, which disrupt melatonin and deep sleep
- Over-reliance on air conditioning, which dries the airway and increases snoring
- Common smoking/shisha habits, which worsen airway inflammation
In our clinics, we routinely counsel patients on realistic sleep improvement strategies—tailored for UAE lifestyles.
Diagnosis and Treatment: What to Expect
Diagnosis may include:
- Sleep history and symptom evaluation
- A home sleep study (in many cases, no hospital stay required)
- Oxygen and heart monitoring overnight
- ECG, Holter monitor, or echocardiogram to assess your heart’s response
Treatment may involve:
- Lifestyle adjustments (weight loss, sleep positioning)
- CPAP or BiPAP therapy to keep the airway open
- Medication review or adjustments
- Cardiovascular monitoring and follow-up care
Our integrated approach means your heart and sleep concerns are addressed together, rather than in isolation.
Breathing Easy, Sleeping Strong
Many patients feel embarrassed or hesitant to talk about sleep problems. But if you’re dealing with snoring, exhaustion, or unexplained heart symptoms, your sleep may be the missing piece of the puzzle.
At KidsHeart, our cardiology team in Dubai, Abu Dhabi, and Al Ain works with pulmonologists and sleep specialists to connect the dots between sleep and heart health.
