90% of People Over 60 Still Sleep in the Wrong Position, Increasing Their Risk of Stroke and Blood Clots
90% of People Over 60 Still Sleep in the Wrong Position, Increasing Their Risk of Stroke and Blood Clots
For millions of Americans over the age of 60, getting a good night’s sleep is a top priority. But according to sleep specialists and cardiologists, how you sleep may be almost as important as how long you sleep. While social media often claims that one sleeping position can directly cause a stroke or blood clot, medical experts say the reality is more nuanced.
There is no definitive evidence that a single sleeping position alone causes strokes or blood clots. However, certain positions can worsen underlying conditions—such as obstructive sleep apnea, acid reflux, or poor circulation—that are known to increase cardiovascular risk over time. For older adults already living with high blood pressure, heart disease, diabetes, or obesity, making simple adjustments to sleep posture may support better overall health.
Here’s what doctors say seniors should know.
Why Sleep Position Matters More After Age 60
As people age, the body undergoes several changes that can affect sleep and circulation.
These include:
Reduced muscle tone in the airway
Increased risk of sleep apnea
Stiffer blood vessels
Slower circulation
More frequent nighttime awakenings
Higher rates of heart disease and high blood pressure
Many adults over 60 also take medications or have chronic conditions that make quality sleep especially important.
During sleep, the heart continues working to pump blood throughout the body. When breathing becomes interrupted or circulation is compromised, the cardiovascular system may experience additional stress.
Sleeping Flat on Your Back: Helpful for Some, Problematic for Others
Sleeping on the back is often recommended for spinal alignment, but it may not be the best choice for everyone.
For individuals with obstructive sleep apnea, lying flat on the back allows gravity to pull the tongue and soft tissues backward, narrowing the airway. This can increase:
Loud snoring
Pauses in breathing
Drops in oxygen levels
Nighttime spikes in blood pressure
Stress hormone release
Over months or years, untreated sleep apnea has been linked to an increased risk of:
High blood pressure
Irregular heart rhythms
Heart attack
Stroke
For this reason, sleep specialists often advise people with sleep apnea to avoid sleeping on their backs whenever possible.

Does Sleeping Position Cause Blood Clots?
One common misconception is that sleeping in the “wrong” position causes blood clots overnight.
In reality, sleeping position alone is not considered a direct cause of deep vein thrombosis (DVT).
Blood clots are more commonly associated with:
Long periods of immobility
Recent surgery
Certain cancers
Smoking
Obesity
Hormone therapy
Inherited clotting disorders
However, remaining inactive for prolonged periods—whether during long flights, hospitalization, or extended bed rest—can contribute to clot formation.
For healthy adults who move normally throughout the day, changing sleep position is unlikely to prevent blood clots by itself.
Side Sleeping May Offer Several Benefits
Many physicians recommend side sleeping for older adults, particularly those who snore or have mild sleep apnea.
Potential benefits include:
Improved airflow
Reduced snoring
Better oxygen levels during sleep
Less nighttime acid reflux
More stable breathing patterns
Sleeping on either side also helps keep the airway more open than lying flat on the back in many individuals.
Is the Left Side Better?
Some cardiologists suggest that left-side sleeping may benefit certain people with cardiovascular conditions.
Possible advantages include:
Improved blood flow back to the heart
Reduced pressure on major blood vessels
Better circulation during pregnancy
Less acid reflux for some individuals
However, others may find the right side more comfortable, especially if they have certain heart or lung conditions. The best position often depends on an individual’s health and comfort.
Who Should Pay Special Attention?
Older adults with the following conditions may benefit from discussing sleep habits with their healthcare provider:
High blood pressure
Atrial fibrillation
Coronary artery disease
Previous stroke or transient ischemic attack (TIA)
Diabetes
Obesity
Chronic snoring
Diagnosed or suspected sleep apnea
If a bed partner notices frequent pauses in breathing or gasping during sleep, a formal sleep evaluation may be recommended.
Other Nighttime Habits That Can Affect Cardiovascular Health
Sleep position is only one part of healthy sleep.
Doctors also recommend:
Maintain a Consistent Sleep Schedule
Going to bed and waking up at similar times each day helps regulate the body’s internal clock.
Avoid Heavy Meals Before Bed
Late-night meals can worsen acid reflux and disrupt sleep quality.
Limit Alcohol
Alcohol may relax airway muscles, increasing the severity of snoring and sleep apnea.
Keep Blood Pressure Controlled
Taking prescribed medications as directed and monitoring blood pressure remain among the most effective ways to reduce stroke risk.
Stay Physically Active
Regular exercise supports healthy circulation and lowers the risk of many cardiovascular diseases.
Warning Signs That Should Never Be Ignored
Seek emergency medical care immediately if you experience any symptoms of stroke, including:
Sudden numbness or weakness on one side of the body
Facial drooping
Difficulty speaking or understanding speech
Sudden confusion
Vision changes
Loss of balance or coordination
A sudden, severe headache with no known cause
Remember the FAST warning signs:
F – Face drooping
A – Arm weakness
S – Speech difficulty
T – Time to call emergency services immediately
Rapid treatment can significantly improve outcomes.
Tips for Sleeping More Comfortably and Safely
Simple strategies may improve sleep quality:
Sleep on your side if back sleeping worsens snoring or sleep apnea.
Use a supportive pillow to keep your neck aligned.
Maintain a healthy weight.
Stay hydrated throughout the day.
Avoid smoking.
Discuss persistent snoring or excessive daytime sleepiness with your healthcare provider.
Follow treatment plans for high blood pressure, diabetes, and heart disease.
For individuals diagnosed with obstructive sleep apnea, treatments such as continuous positive airway pressure (CPAP) therapy can substantially improve breathing during sleep and reduce cardiovascular strain.
The Bottom Line
While dramatic claims online may suggest that “the wrong sleeping position” directly causes strokes or blood clots, the scientific evidence does not support that conclusion. Sleeping position alone is not a proven cause of either condition.
However, for many adults over 60—especially those with obstructive sleep apnea, high blood pressure, or existing cardiovascular disease—sleeping flat on the back may worsen breathing disturbances that contribute to long-term cardiovascular stress. Side sleeping may improve airflow and sleep quality for some individuals, but it is only one part of an overall strategy for healthy aging.
The most effective ways to lower the risk of stroke and blood clots remain well established: keep blood pressure under control, manage diabetes and cholesterol, stay physically active, avoid smoking, maintain a healthy weight, and seek medical evaluation for persistent snoring or suspected sleep apnea. Combining these habits with healthy sleep practices can help support both heart and brain health for years to come.
