World Sleep Day 13th March 2026 Sleep Apnea: The Silent Night-Time Threat to Your Heart and Health

“Sleep apnea is not just snoring. It is a serious health condition that silently affects oxygen supply to the body and increases the risk of heart disease, stroke, and metabolic disorders. Early diagnosis and proper treatment can significantly improve both sleep quality and overall health.”

— Dhiren Shah, Director – Cardiothoracic & Vascular Surgery Department, Director – Heart-Lung Transplant Programme & MCS Programme

1. What is Sleep Apnea?

Sleep Apnea is a serious sleep disorder in which breathing repeatedly stops and starts during sleep. These pauses reduce oxygen levels in the body and disturb the natural sleep cycle. If left untreated, sleep apnea can increase the risk of heart disease, stroke, diabetes, and high blood pressure.

2. What are the common symptoms of Sleep Apnea?

Common symptoms include loud snoring, choking or gasping during sleep, excessive daytime sleepiness, morning headaches, poor concentration, and fatigue. Often, family members notice breathing pauses during sleep before the patient becomes aware of the problem.

3. What causes Sleep Apnea?

Sleep apnea usually occurs when the airway becomes partially or completely blocked during sleep. Factors such as obesity, enlarged tonsils, a thick neck circumference, aging, and certain lifestyle habits can increase the risk of airway obstruction.

4. Who is at higher risk of developing Sleep Apnea?

People who are overweight, individuals above the age of 40, men under 40, and women after menopause are at higher risk. Conditions such as hypertension, diabetes, and sedentary lifestyle habits also increase the likelihood of developing sleep apnea.

5. Why is Sleep Apnea often undiagnosed?

Many people assume snoring and daytime tiredness are normal, which leads to delayed diagnosis. Since breathing interruptions happen during sleep, patients may not realize the problem unless someone observes it.

6. How does Sleep Apnea affect heart health?

Sleep apnea repeatedly lowers oxygen levels in the body, which places continuous stress on the heart and blood vessels. Over time, it can increase the risk of hypertension, heart disease, stroke, and irregular heart rhythms.

7. Can Sleep Apnea affect daily life and productivity?

Yes. Poor sleep quality caused by sleep apnea can lead to fatigue, lack of concentration, mood disturbances, and daytime sleepiness. This can affect work performance, decision-making ability, and overall quality of life.

8. How is Sleep Apnea diagnosed?

Doctors usually recommend a sleep study, also called polysomnography, which monitors breathing patterns, oxygen levels, and sleep stages during the night. This helps confirm the presence and severity of sleep apnea.

9. What treatment options are available for Sleep Apnea?

Treatment may include lifestyle changes such as weight management, regular exercise, and avoiding alcohol before bedtime. In moderate to severe cases, doctors may recommend CPAP therapy or other specialized medical treatments.

10. When should someone consult a doctor for Sleep Apnea?

If you experience loud snoring, breathing pauses during sleep, persistent daytime fatigue, or morning headaches, it is important to seek medical advice. Early diagnosis and treatment can prevent serious long-term health complications.
