Experiencing numbness or tingling in your hands from time to time is fairly common, especially after waking up or keeping your arm in the same position for an extended period. However, when the sensation becomes frequent, persistent, or severe, it may indicate a deeper issue that requires medical attention.
This sensation is medically known as paresthesia, which includes symptoms such as tingling, numbness, or a “pins and needles” feeling. While occasional numbness is usually harmless and temporary, persistent paresthesia could be a sign of nerve dysfunction, circulatory issues, or chronic medical conditions.
In this article, we explore the common causes of hand numbness, when to seek medical attention, and the possible health conditions associated with it—based on scientific research and official health sources like the National Institutes of Health (NIH), Mayo Clinic, and the Cleveland Clinic.
