Tracking Shakiness and Tremor Day to Day
Tremor is an involuntary rhythmic movement of the hands, arms, head, voice, or legs. Some people describe an outward shake others can see, some describe an internal buzzing or vibration that nobody else notices. It can arrive with a coffee, a missed meal, a stressful meeting, or for no obvious reason at all. Because tremor comes and goes, memory alone rarely captures it accurately. A written record of when it appears, and what your body was doing at the time, is far more useful in a ten minute appointment.
Why track this symptom?
- Tremor fluctuates by hour, so a record shows what a single clinic visit cannot.
- Caffeine, skipped meals, and poor sleep amplify shaking in ways a timeline exposes.
- Noting whether it shakes at rest or in action gives your clinician the key clinical split.
How Trace Health helps
Shakiness often passes within minutes, so logging has to be fast. Trace Health takes one tap for mild, moderate, or severe, and you can add a note about whether your hand was resting, holding a cup, or reaching. Caffeine, meals, sleep, stress, exercise, and medications sit on the same timeline, so amplifiers show up as patterns rather than guesses.
Common causes
Most everyday shakiness is physiological tremor turned up by something: caffeine, nicotine, low blood sugar, poor sleep, adrenaline from anxiety or panic, hard exercise, or an inhaler such as salbutamol. Alcohol withdrawal produces a coarse tremor within 6 to 24 hours of the last drink. An overactive thyroid causes a fine fast tremor alongside weight loss, heat intolerance, and a racing pulse. Lithium, valproate, some antidepressants, and steroids are common drug causes. Essential tremor is an action tremor, worst when holding a cup or writing, often familial, often improved briefly by alcohol. Parkinson's disease typically causes a rest tremor in one hand that eases with movement, with slowness and stiffness. Less commonly, tremor follows dystonia, cerebellar disease, multiple sclerosis, neuropathy, or low magnesium.
When to see a doctor
Seek urgent care if tremor starts suddenly with weakness on one side, slurred speech, drooping face, double vision, or trouble walking. Also urgent: shaking with confusion, fever above 38.5°C (101.3°F), a stiff jerky body after starting a new psychiatric drug, or tremor during alcohol withdrawal with sweating and hallucinations, which can progress to seizures. Severe shaking with sweating and confusion may be very low blood sugar and needs sugar immediately. Book a routine appointment if tremor is new, steadily worsening over months, affects one side only, interferes with writing, eating, or work, or began within weeks of a new medication.
Frequently Asked Questions
Why do my hands shake when I haven't eaten?
Falling blood sugar triggers an adrenaline response, and adrenaline amplifies the normal physiological tremor everyone has. The result is fine, fast shaking, often with hunger, sweating, irritability, and a fast heartbeat, usually settling 10 to 20 minutes after eating. It is common in people who skip breakfast, train fasted, or take diabetes medication. Log the time of your last meal, what the meal contained, how long the shaking lasted, and whether food fixed it. If shaking happens repeatedly despite regular eating, or you take insulin or sulfonylureas, discuss glucose testing with your clinician.
How much caffeine causes tremor?
There is no universal threshold, and sensitivity varies widely. Many people notice hand shaking above roughly 200 to 400 mg a day, which is about two to four cups of brewed coffee, but people with anxiety, thyroid overactivity, or an existing tremor can react to much less. Energy drinks, pre-workout powders, strong tea, and some painkillers add to the total. Effects usually peak 30 to 60 minutes after drinking and can persist for hours in slow metabolizers. Log every caffeinated drink with the time and the tremor severity alongside it. A two week reduction, tapered to avoid headaches, usually makes the link clear.
What is the difference between essential tremor and Parkinson's tremor?
The situation in which the shaking appears is the most useful distinction. Essential tremor is an action tremor: hands are steady in the lap but shake when holding a cup, using a spoon, or writing. It is often symmetrical, may involve the head or voice, frequently runs in families, and can ease temporarily with a small amount of alcohol. Parkinson's tremor is typically a rest tremor: the hand shakes while resting and quiets when you reach for something. It usually starts on one side and comes with slowness, small handwriting, reduced arm swing, and stiffness. Log which position provokes it, and both hands separately.
When should I worry about shaky hands?
Get emergency care if shaking comes on suddenly with one-sided weakness, slurred speech, facial droop, or difficulty walking, or if it accompanies confusion, high fever, or severe alcohol withdrawal with sweating and hallucinations. Arrange a routine appointment within a few weeks if tremor is new for you, is clearly worse on one side, has progressed over months, makes eating, writing, or holding a phone difficult, or started after a change in medication such as lithium, valproate, an antidepressant, or an inhaler. Weight loss, heat intolerance, and palpitations alongside tremor warrant thyroid testing.
What should I bring to a neurology appointment about tremor?
Bring answers to four questions: when it started, which body parts are involved, what position brings it out (resting, holding a posture, or moving toward a target), and what makes it better or worse, including alcohol, caffeine, sleep, and stress. List every medication and supplement with doses and start dates. A short video of your hands at rest and while holding a cup is genuinely useful. A Trace Health report puts your severity entries, triggers, and lifestyle factors on one timeline as a doctor-ready PDF, so the pattern is visible without relying on memory.

Everything is right there, there’s widgets, it’s fast and simple and syncs! I freaking love this app! I’m still playing with it so I haven’t seen if it has a “how are you feeling right now” feature but it is everything I have ever wanted the symptoms on health to be!” (grofica82, United States)
