The memory loss of patients after staying up late can be restored, when memory loss is caused by brain cells in a state of fatigue and brain nerve function disorder. When the patient sleeps regularly, the patient’s brain memory function can be completely restored. Patients are advised not to stay up late often and to develop the habit of regular rest and relaxation. Patients are advised to eat more green leafy vegetables after staying up late, and fruits rich in vitamins can help improve patients’ memory. Patients are usually advised to eat more dried fruits, such as pine nuts, almonds, walnuts and pistachios, which can play a brain-boosting role and can help patients’ memory recovery. Patients must develop the habit of regular work and rest and avoid staying up late.
