Patients who get dizzy and get better after a nap may be due to the following reasons: 1. Consider that it is because of brain nerve dysfunction, neurasthenia, and lack of sleep that causes patients to have dizzy symptoms. In the process of sleeping, the nerves of the brain will be partly restored, and after the brain gets sufficient rest, the patient’s dizziness will be improved. 2. The patient’s dizziness may be caused by migrainous vertigo disease, which usually occurs under the stimulation of exertion, poor sleep or diet. The symptoms of headache and dizziness will be relieved after rest. 3. Patients who get better after taking a nap may also be related to stressful reasons, if they are under stress and emotional tension, their symptoms will improve when they are well rested.
