Introduction
In general, uncontrollable trembling due to physical tension may be caused by sympathetic nervous system activation, excessive muscle tightness, essential tremor, hyperthyroidism, Parkinson's disease, or other conditions. If symptoms occur frequently, it is recommended to seek timely medical evaluation at a正规 hospital. In daily life, maintain a regular sleep schedule and avoid staying up late; learn relaxation techniques such as meditation and progressive muscle relaxation.
Generally, uncontrollable trembling when the body is tense may be caused by sympathetic nervous system activation, excessive muscle tension, essential tremor, hyperthyroidism, Parkinson's disease, or other reasons. If symptoms occur frequently, it is recommended to seek timely medical evaluation at a reputable hospital. Specific causes are analyzed as follows:
1. Sympathetic Nervous System Activation
When anxious, the sympathetic nervous system becomes abnormally activated, increasing adrenaline secretion and elevating muscle excitability, which leads to trembling. Immediately stop current activities, practice deep breathing, cross your arms to apply gentle pressure for relaxation, and shift attention to calming stimuli.
2. Excessive Muscle Tension
Under stress, sustained muscle contraction throughout the body increases energy consumption, potentially leading to cramping and trembling. Gently stretch muscles in the limbs, shoulders, and neck; apply warm towels to the body; and maintain a quiet, comfortable environment.
3. Essential Tremor
A hereditary movement disorder in which imbalances in brain neurotransmitters worsen limb tremors during periods of anxiety. Medications such as propranolol tablets, atenolol tablets, or gabapentin capsules may be used under medical guidance. Avoid consuming coffee and strong tea.
4. Hyperthyroidism
Excessive thyroid hormone secretion accelerates metabolism and increases neuromuscular excitability, exacerbating tremors during stress. Medications such as methimazole tablets, propylthiouracil tablets, or extended-release propranolol may be taken under a doctor’s supervision, with regular monitoring of thyroid function.
5. Parkinson’s Disease
Degeneration of dopamine-producing neurons in the brain leads to impaired motor control, resulting in prominent resting tremors during stress. Treatments include levodopa-carbidopa tablets, extended-release pramipexole, or extended-release piribedil, as prescribed. In severe cases, deep brain stimulation surgery may be considered.
In daily life, maintain regular sleep patterns and avoid staying up late; learn relaxation techniques such as meditation and progressive muscle relaxation; eat a balanced diet to ensure adequate nutrition and reduce intake of stimulating foods; and undergo regular physical check-ups to detect and manage underlying conditions early.
