If your hands have a mind of their own, you’re not alone. Essential tremor (ET) is a neurological disorder that causes rhythmic shaking, usually in the hands, but sometimes in the head, voice, or even legs. It’s the most common type of tremor, often mistaken for Parkinson’s disease, but with its own unique quirks.

ET tends to run in families—so if your dad spilled coffee with flair, there’s a 50/50 chance you might too. It usually shows up after age 65, but younger folks can experience it as well. The cause? Still a mystery, but experts suspect poor communication between brain parts like the cerebellum.

Symptoms worsen during movement (not rest), and things like stress, caffeine, or even some medications can make it worse. Oddly enough, a little alcohol might calm the shakes—cheers to that?

Diagnosis is clinical, often requiring tests to rule out other causes. Treatments include medications like propranolol or primidone, which can calm the tremors but come with side effects. Botox and deep brain stimulation surgery are options for severe cases.

Lifestyle changes can also help: avoiding stimulants, managing stress, and checking your medications. While ET isn’t dangerous, it can be frustrating and even disabling over time. The good news? With the right help, something as simple as yoga, you may be able to steady the course and feel better.
