Sleep Disorders & Stroke Risk | What You Need to Know
By Dr. Amit Sahu – Interventional Radiologist & Interventional NeuroRadiologist, Mumbai
Sleep is one of the most vital processes for the human body. It allows the brain and body to rest, repair, and regulate vital functions.
However, when sleep is disturbed either in quality or duration it can have serious effects on brain health, including an increased risk of stroke.
Research has shown that people with sleep disorders such as sleep apnea, insomnia, or restless leg syndrome are at a significantly higher risk of developing a stroke.
Dr. Amit Sahu, a leading Interventional NeuroRadiologist in Mumbai, explains how sleep disorders increase stroke risk, and how timely diagnosis and treatment can save lives.
Understanding the Link Between Sleep and Stroke
How Sleep Affects Brain and Blood Vessels?
During sleep, your body undergoes several restorative processes.
Blood pressure drops, heart rate slows, and the brain clears out toxins that accumulate during the day.
When you don’t get quality sleep, it disrupts these mechanisms, leading to:
- Increased blood pressure (hypertension)
- Reduced oxygen flow to the brain
- Higher inflammation levels in blood vessels
- A greater risk of clot formation
Over time, these factors contribute to the hardening and narrowing of arteries, significantly increasing the risk of a stroke.
Why Are Stroke Risks Higher at Night?
Studies show that stroke risk is higher at night or early morning, often between midnight and 6 a.m. This happens because:
- Blood pressure naturally dips during sleep and may not rise fast enough upon waking
- Sleep apnea episodes can cause sudden drops in oxygen levels
- Heart rhythm changes during deep sleep can trigger clots or vascular stress
If you or a loved one snores heavily or frequently wakes up gasping for air, it may be a sign of sleep apnea, a major risk factor for stroke.
Common Sleep Disorders Linked to Stroke
Sleep Apnea and Stroke
Sleep apnea is one of the most common and dangerous sleep disorders.
It causes repeated pauses in breathing during sleep, leading to low oxygen levels and increased strain on the heart and brain.
Can sleep apnea cause a stroke?
Yes, untreated sleep apnea can double or even triple the risk of strokes. The constant oxygen deprivation and blood pressure spikes damage blood vessels over time.
Signs of sleep apnea include:
- Loud, chronic snoring
- Episodes of stopped breathing during sleep
- Gasping or choking while sleeping
- Daytime sleepiness or fatigue
- Morning headaches or irritability
Getting tested for sleep apnea and treating it early is essential for preventing stroke and other heart-related complications.
Insomnia and Stroke
Insomnia, or chronic difficulty falling asleep or staying asleep, disrupts the body’s stress and hormone regulation. This can lead to:
- Elevated cortisol levels
- Increased blood pressure
- Vascular inflammation
Over time, these changes increase the risk of cardiovascular issues, including stroke.
Restless Leg Syndrome (RLS) and Stroke
RLS is characterized by an uncontrollable urge to move the legs at night, often leading to disturbed sleep.
This sleep fragmentation contributes to poor circulation and higher stroke risk, especially in older adults or those with metabolic conditions.
What Sleep Disorders Cause Stroke?
Sleep disorders that have been scientifically linked to increased stroke risk include:
- Obstructive Sleep Apnea (OSA)
- Insomnia
- Restless Leg Syndrome (RLS)
- Circadian Rhythm Disorders
Recognizing the Signs Early
Symptoms of Sleep Disorders You Shouldn’t Ignore
- Persistent fatigue despite adequate sleep
- Loud snoring or interrupted breathing
- Morning headaches or brain fog
- Difficulty concentrating or irritability
- Restless legs or frequent nighttime awakenings
Signs of Sleep Apnea
Be especially alert if you notice:
- Loud snoring and gasping during sleep
- Pauses in breathing noticed by your partner
- Dry mouth or sore throat upon waking
- Difficulty focusing or excessive sleepiness during the day
If these symptoms persist, consult a specialist immediately for evaluation and treatment.
When to See a Specialist?
Consulting an Expert for Sleep and Stroke Prevention
If sleep issues persist or you notice warning signs of a sleep disorder, it’s crucial to consult a specialist early.
A NeuroInterventional Radiologist can help identify underlying vascular issues and recommend appropriate preventive or treatment strategies.

FAQs About Sleep Disorders and Stroke
- Can sleep apnea cause a stroke?
Yes. Sleep apnea causes oxygen levels to drop during sleep, which increases blood pressure and puts strain on the brain’s blood vessels, making stroke more likely.
- What sleep disorders cause stroke?
Sleep apnea, insomnia, restless leg syndrome, and circadian rhythm disorders are all associated with an increased risk of stroke.
- Why are stroke risks higher at night?
Stroke risks rise at night because of lower blood pressure, reduced oxygen levels, and changes in heart rhythm — especially in people with sleep apnea.
- What are the best ways to prevent a stroke?
Maintain good sleep hygiene, treat any underlying sleep disorders, control blood pressure, eat a healthy diet, and avoid smoking or excessive alcohol.
- What is the best sleep position after stroke?
Sleeping on your side is generally best after a stroke as it helps with breathing and reduces airway blockage, especially for those with sleep apnea.
- Who is the best doctor for brain stroke in Mumbai?
Dr. Amit Sahu, an expert Interventional NeuroRadiologist, is among the best doctors for brain stroke in Mumbai, offering world-class stroke and paralysis treatments using minimally invasive techniques.
