Patients with viral hepatitis should avoid staying up late at night, because the liver rests and detoxifies during night hours. Staying up late might lead to liver function damage. For a healthy individual, staying up late might cause mild liver function abnormalities the following day. Over time, if a patient with viral hepatitis continues to stay up late, their liver function may repeatedly become abnormal. Even if their virus status is negative and they are just carriers, their long-term poor lifestyle habits could lead to the onset of hepatitis. Therefore, it is crucial for patients with viral hepatitis to avoid staying up late and drinking alcohol.
