Back Pain and Chronic Dehydration

This article describes some observations about a possible connection between not drinking enough water and suffering from back pain. The guest author is James Lehman, DC, who is a professor of orthopedics and neurology at the University of Bridgeport College of Chiropractic.

Why Hydration Matters for Your Spine

The intervertebral discs that cushion the bones of the spine depend heavily on water. The gel-like center of a healthy disc, the nucleus pulposus, has a high water content, which helps it resist compression and spread load evenly. Discs have very little direct blood supply, so they rely on the movement of fluid in and out of the disc to receive nutrients and remove waste products.

Discs naturally lose some fluid during the day under the load of standing and sitting, and regain it while you lie down at night. This is why most people are slightly taller in the morning than in the evening. With age, discs gradually lose some of their ability to hold water, which is part of normal disc aging.

What the Evidence Does and Does Not Show

Water is clearly essential for healthy disc structure and function. However, research has not shown that drinking more water will prevent or cure back pain on its own. Back pain has many contributing factors, including physical activity, posture and workload, sleep, stress and general health. Staying well hydrated is best seen as one part of a healthy routine that supports your spine, not a standalone treatment.

Practical Hydration Tips

• Drink water regularly through the day rather than large amounts at once
• Keep a water bottle at your desk; refilling it also gives you a reason to stand up and move
• Drink more in hot weather, during exercise and when you are ill with a fever
• Pale yellow urine is a simple sign that you are generally well hydrated
• If you have heart, kidney or liver disease, ask your doctor how much fluid is right for you

Other Habits That Support a Healthy Back

Pair good hydration with regular activity, movement breaks and a supportive workstation; see our guides to ergonomic desk setup and the best sleeping positions for back pain.
