The main reason why shivering easily occurs when you are nervous and anxious is that nervousness is accompanied by plant nerve dysfunction, especially increased secretion of adrenaline. In addition to shivering, other physical symptoms may also occur, such as headache, dizziness, nausea, vomiting, upper abdominal discomfort, stomach pain, loss of appetite, and muscle tension and stiffness, especially in the back of the neck and back, as well as various discomforts throughout the body. There may also be behavioral symptoms, such as fidgeting, a particularly tense expression, and walking back and forth. If the problem of tension accompanied by trembling has already appeared, it must be actively adjusted and treated. Consider taking medication, such as taking glutamate, vitamin B1 for treatment, or consider benzodiazepines, such as lorazepam, oxazepam and other short-acting benzodiazepines for symptomatic treatment.
