why am i shaking so much

Shaking or tremors can happen for many reasons, commonly including stress or anxiety, fatigue or sleep deprivation, high caffeine intake, and intense exercise. They can also be caused by neurological conditions like Parkinson's disease or multiple sclerosis, low blood sugar, medications, alcohol withdrawal, overactive thyroid, or essential tremor, which is a neurological disorder causing uncontrollable shaking. If the shaking is temporary, it might be related to a stimulant or stress, but if it persists or worsens, it is important to seek medical evaluation to identify the underlying cause.
