What causes whole-body tremors?

In general, whole-body tremors refer to involuntary shaking of the body, which may be caused by factors such as cold exposure, anxiety, common cold, hyperthyroidism, Parkinson's disease, and others. Symptomatic treatment should be conducted under a doctor's guidance. Specific causes are analyzed as follows:

1. Cold Exposure

When the body is exposed to cold environments, it automatically begins to shiver in order to generate heat and maintain body temperature. It is important to keep warm promptly by wearing thick clothing or adding extra blankets.

2. Anxiety

When a person is in a state of tension or anxiety, whole-body tremors may also occur. Psychological counseling and relaxation techniques can help ease both mind and body.

3. Common Cold

If a cold is caused by a viral infection, it may also lead to whole-body tremors. A warm water sponge bath can be used for physical cooling; once body temperature decreases to a certain level, the shivering may subside.

4. Hyperthyroidism

Hyperthyroidism refers to excessive production of thyroid hormones by the thyroid gland, leading to an increased metabolic rate. This can affect nervous system function and result in uncontrollable muscle tremors. Patients may take medications such as propylthiouracil tablets or carbimazole tablets under medical supervision.

5. Parkinson’s Disease

Parkinson’s disease is a chronic, progressive neurological disorder that commonly causes symptoms such as muscle rigidity, reduced movement, and tremors. The tremor associated with Parkinson’s disease is typically a resting tremor—occurring when the body is at rest—especially affecting the hands, legs, jaw, and around the lips. Tremors often begin mildly and may become more pronounced as the disease progresses. Patients may take medications such as trihexyphenidyl hydrochloride tablets or amantadine hydrochloride tablets under a doctor’s guidance.

It is advisable to drink plenty of warm water and increase caloric intake in the diet. If whole-body tremors persist for a prolonged period or are accompanied by other symptoms, prompt medical attention is recommended.
