Tremors: Types, Causes, and When to Seek Help

When you notice an unwanted shake, you’re experiencing Tremors, involuntary rhythmic movements of a body part, often the hands, arms, or legs, also known as shaking. Tremors can range from a mild buzz you barely notice to a vigorous quiver that interferes with daily tasks. Understanding why they happen helps you decide whether to monitor, adjust lifestyle, or see a doctor.

One common form is Essential tremor, a hereditary, action‑related shaking that usually appears during voluntary movements like writing or lifting a cup. It tends to run in families and often shows up after age 40. Another frequent culprit is medication‑induced tremor, a side‑effect caused by drugs that affect the central nervous system, such as certain antidepressants, asthma inhalers, or cancer therapies. When you start a new prescription, watch for a subtle tremor; it may be a signal to discuss dosage adjustments with your prescriber. Parkinson's disease, a progressive neurodegenerative disorder characterized by a resting tremor, rigidity, and slowed movement is another major source, where the shake often begins on one side and eases when the limb is in motion.

Other Triggers You Might Overlook

Beyond the classic neurological conditions, several metabolic and lifestyle factors can spark a tremor. Low phosphate levels, known as hypophosphatemia, weaken muscles and may produce a fine tremor alongside fatigue. Caffeine, nicotine, and high‑stress moments amplify the nervous system’s excitability, turning a calm hand into a jittery one. Certain vitamin deficiencies—especially B‑12 and magnesium—disrupt nerve signaling and can manifest as shaky hands. If you notice the tremor worsening after a workout, an intense coffee binge, or during periods of anxiety, consider these reversible contributors before labeling it as a chronic issue.
