Tremors can happen at any age. They are more common in older people. Everyone has some tremor when they move their hands. Stress, fatigue, anger, fear, caffeine, and smoking may make this type of tremor worse.
A tremor that does not go away over time may be a sign of a medical problem and should be checked by your health care provider.
Essential tremor is the most common type of tremor. The shaking most often involves small, rapid movements. It usually occurs when you are trying to do something, such as reaching for an object or writing. This type of tremor may also run in families.
Tremor may be caused by:
Your provider will likely suggest self-care measures to help with daily life.
For tremors caused by stress, try ways to relax, such as meditation or breathing exercises. For tremors of any cause, avoid caffeine and get enough sleep.
For tremors caused by a medicine, talk to your provider about stopping the drug, reducing the dosage, or switching to another medicine. Do not change or stop medicines on your own.
For tremors caused by alcohol use, seek treatment to help you stop drinking alcohol.
Severe tremors may make it hard to do daily activities. You may need help with these activities.

You may not need treatment unless the tremor interferes with your daily activities or causes embarrassment.
Treatment depends on the cause. Tremor caused by a medical condition, such as hyperthyroidism, will likely get better when the condition is treated.
If the tremor is caused by a certain medicine, stopping the drug will usually help it go away. Never stop taking any medicine without first talking to your doctor.
You may be prescribed medicines to help relieve symptoms. How well medicines work depends on your overall health and the cause of the tremor.
In some cases, surgery is done to relieve the tremors.
