Wearing wrist splints while you sleep may be all you need to treat the numbness and tingling of early-stage carpal tunnel syndrome, says a study in the Archives of Physical Medicine and Rehabilitation. Carpal tunnel syndrome occurs when the wrist’s median nerve is compressed for long periods, such as during repeated motion. The study involved workers at an automotive plant who showed early symptoms of the syndrome—burning, tingling, numbness and pain in the hand. Those who wore splints every night for six weeks found their symptoms’ severity lessened by almost half. If you suffer from early symptoms, it may be worth giving splints (available at drugstores) a six-week trial. No improvement? Talk to your doctor. Left untreated, the condition can cause permanent nerve damage.
