Beyond Neck Pain: How Your Smartphone Is Affecting Your Heart, Eyes, and Nervous System

January 06, 2026

That device in your hand as you read this? It's quietly impacting your heart, eyes, sleep, and nervous system in ways you never expected. As your local chiropractor in Toronto, Yorkville Chiropractic and Wellness Centre sees an awful lot of tech-related issues, and the latest research reveals the issue runs deeper than you may imagine. It's not always "just' neck pain. Our gentle spinal manipulation treatment can help!

YOUR SPINE AFFECTS YOUR HEART

You might be amazed to learn that 'text neck' is doing more damage than causing neck pain alone. New studies show it's directly impacting your autonomic nervous system—the part managing your heart rate, blood pressure, and stress response. (1) When your head shifts forward into "text neck" position, it sets up compression in your upper cervical spine, interfering with proper nerve signaling and triggering your sympathetic nervous system. Your body stays in fight-or-flight mode, increasing heart rate and blood pressure—all from looking down at your phone. Weird to think about, but you are not the only one feeling these effects!

THE SPINE-EYE CONNECTION YOU NEED TO KNOW

Researchers are now documenting "cervical oculopathy"—where neck misalignments cause vision problems ranging from blurry vision, eye pain, dry eyes, to even contributing conditions like glaucoma. (2) When your cervical spine is misaligned, it can compress blood vessels and nerves supplying your eyes. Studies found that patients with chronic, unexplained visual symptoms often show significant cervical spine issues and compressed jugular veins, impairing drainage from the brain and eyes.

WHY DIFFICULT TASKS MAKE EVERYTHING WORSE

When researchers measured how people hold their phones, they discovered that challenging tasks lead to worse posture. (3) Typing creates neck flexion angles exceeding 30 degrees while watching videos averages around 26 degrees. People who use phones more heavily develop even more extreme flexion angles—a downward spiral affecting spinal alignment with every text.

THE REAL RISK FACTORS MIGHT SURPRISE YOU

After tracking patients for a full year, researchers discovered that phone posture wasn't actually the leading predictor of neck problems. (4) Instead, poor sleep quality and lack of physical activity were the real culprits triggering neck pain. The lifestyle factors that come with heavy phone use—disrupted sleep and sedentary behavior—may cause even more musculoskeletal damage.

This research reinforces our healthcare approach at Yorkville Chiropractic and Wellness Centre. Regular chiropractic adjustments maintain proper cervical alignment and nervous system function, but you also need quality sleep and physical activity. When using your phone, bring it closer to eye level, especially when typing, and take breaks often.

Your nervous system controls everything. When smartphone habits compromise your spinal health, the effects travel. Keeping proper spinal alignment via regular chiropractic care may well protect your heart, eyes, sleep, and overall nervous system function for the long term.
