What Causes Dizziness Due to Sleep Deprivation?

Sleep deprivation–induced dizziness commonly occurs because inadequate sleep typically weakens the body’s immune function, increasing susceptibility to bacterial or viral infections—such as the common cold—which can then cause dizziness. Moreover, sleep deprivation may lead to neurasthenia and neurological dysfunction, both of which can also contribute to dizziness. Improving sleep duration often alleviates these symptoms; when necessary, symptom-targeted medications may be prescribed under a physician’s guidance.
