Seniors: This Sleeping Position Raises Your Stroke Risk

Left-Side Specific Benefits: Sleeping on the left side may improve blood return to the heart due to anatomical positioning, easing cardiac workload. It also helps reduce acid reflux, which can disrupt sleep and increase nocturnal stress.

Actionable Strategy: How to Safely Transition to a Healthier Sleep Posture
Step 1: Optimize Your Pillow
Your pillow should maintain a neutral neck alignment. When lying on your side:

Your head should be level with your spine.

Your chin should not be tucked toward your chest or pushed upward.

Consider a contoured memory foam pillow or an adjustable shredded latex pillow designed for side sleepers.

Step 2: Use the “Pillow Barrier” Method
To prevent rolling onto your back unconsciously:

Place a firm, body-length pillow or a rolled blanket against your back.

Hug another pillow in front of you. This supports the top arm and knee, preventing shoulder and hip strain, and makes side sleeping more comfortable.

Step 3: Consider a Wedge if Back Sleeping is Unavoidable
If you must sleep on your back due to other medical conditions (like severe GERD or certain spinal issues), use a bed wedge pillow to elevate your upper body at a 30-45 degree angle. This can help reduce apnea severity and improve circulation compared to lying flat.

Step 4: Address the Root Cause—Get Screened for Sleep Apnea
Loud snoring, witnessed breathing pauses, and daytime fatigue are red flags. A sleep study (in-lab or at-home) is essential. Treating sleep apnea with a CPAP machine is one of the most powerful stroke-prevention actions a senior can take.

Consistent Sleep Schedule: Maintain regular sleep/wake times to stabilize circadian rhythms and blood pressure patterns.

Blood Pressure Management: Monitor blood pressure in the evening and morning. Discuss with your doctor if nocturnal hypertension is present.
