Some people who are feeling burned out will report dizziness being one of their symptoms. This is not the case for everyone suffering from burnout, however, but it seems to be linked to people who are also experiencing symptoms of nausea and sweating. It is important to note that the root cause of feeling dizzy is not fully understood by clinicians. That said, it appears to be that the vestibular system, the one which regulates how we all feel balance and bodily orientation, can become overloaded by all of the sensory input we have when we are very stressed. As such, it can start to send the wrong sorts of signals to the brain, which, in the end, we notice as dizziness and nausea.
