You can have sex after recovering from a subarachnoid hemorrhage. Moderate sexual intercourse will not have any effect, but it is not recommended to have sex too often. Sex is not recommended during the recovery period because the bleeding is caused by rupture of blood vessels in the arachnoid membrane, and the speed of the blood increases during sex, which may lead to congestion of the blood vessels and reoccurrence of bleeding, aggravating the condition. People with a history of subarachnoid hemorrhage should avoid emotional stress. Excessive sexual activity can lead to a lack of energy, which can affect recovery. People with a history of subarachnoid hemorrhage should avoid strenuous exercise in addition to reducing sexual activity. Subarachnoid hemorrhage should be rested for at least four weeks, during which time the blood pressure should be controlled and the bowel movement should be smooth. To prevent delayed hemangioma, you can choose to take oral nimodipine.
