The symptoms of dizziness and nausea when patients stay up late are related to extreme brain fatigue, body under tension, brain nerve dysfunction, and also brain ischemia and hypoxia. Staying up late can also lead to disorders of the gastrointestinal tract, nausea, vomiting, physical weakness, sleepiness, and severe dizziness. When patients already have these symptoms, they must not continue to stay up late because this condition may induce acute cardiovascular and cerebrovascular problems, such as inducing spasm of cerebral blood vessels, leading to severe dizziness, nausea and vomiting, and easily inducing acute coronary syndrome, leading to angina pectoris. So be sure to pay attention to lifestyle conditioning and avoid staying up late often. In addition to dizziness and nausea problems from staying up late, staying up late for a long time can also lead to disruptions in the patient’s biological clock and problems such as sleep disorders.
