Carpal tunnel syndrome (CTS) occurs when the median nerve becomes compressed or restricted
as it passes through the wrist. Early on, this may cause mild, intermittent tingling, numbness, or pain in
parts of the hand, but over time, symptoms can become more frequent and activity-limiting. While CTS
can develop at any age, it’s most common during midlife due to the convergence of three key factors:
occupational stress, hormonal and metabolic changes, and age-related anatomy.
When we perform frequent, repetitive hand movements, the tendons that run through the carpal
tunnel glide back and forth against one another. Over time, the lubricating sheaths surrounding these
tendons can become inflamed and sustain micro-injuries that need time to recover. However, occupations
or hobbies that involve non-neutral wrist positions, high gripping forces, or vibration exposure often
provide little opportunity for rest. After years—or decades—of repetitive stress, minor irritation can
progress into chronic inflammation that’s difficult to ignore or manage with over-the-counter remedies.
In addition to repetitive movement, hormonal changes and worsening metabolic health during
midlife increase CTS risk. Chronically elevated blood sugar can thicken connective tissue (including the
transverse carpal ligament) and increase fluid retention, both of which reduce space inside the carpal
tunnel and place pressure on the median nerve. Poor metabolic health also damages the microvessels that
supply the nerve and fuel systemic inflammation that can narrow the tunnel even further. Women face an
added risk during this stage of life, as changes in estrogen and thyroid hormones can make tissues less
elastic and more vulnerable to shear forces.
Age-related changes compound the problem. As we grow older, damaged tissues heal and
regenerate more slowly. Tendons thicken, ligaments stiffen, and the myelin sheath that insulates nerves
can begin to thin, leaving the median nerve more susceptible to compression at the carpal tunnel. Muscle
mass naturally declines as well, reducing the stabilizing forces around the wrist. These changes affect not
only the carpal tunnel itself but the entire course of the median nerve—from the neck and shoulder down
through the elbow and forearm—meaning that restriction anywhere along its path can heighten sensitivity
to compression at the wrist.
Fortunately, all is not lost. Although we can’t stop the aging process, we can control occupational
and metabolic risk factors. Adjusting tools to maintain a neutral wrist position, scheduling regular microbreaks, and performing nerve-gliding or wrist-mobility exercises can help reduce pressure in the tunnel.
Supporting overall metabolic health is equally important: limit sugary drinks and ultra-processed foods,
increase fruit and vegetable intake, take daily walks, and aim for 150 minutes of moderate activity plus
two resistance-training sessions per week.
Finally, chiropractic care can help restore normal motion to the wrist and surrounding joints,
reducing strain on the median nerve along its entire pathway. Your chiropractor can also teach you the
most effective exercises for symptom management and guide you on ergonomic adjustments to keep your
wrists healthy long-term.
