When you close your eyes at night, you feel that the blood in the whole body rushes towards your head, which may be due to the sudden increase of blood pressure or mental tension. 1. Sudden rise in blood pressure: when blood pressure rises suddenly, it leads to dilation of blood vessels in the head and face, and the feeling of blood rushing to the head will appear, so it is necessary to closely monitor the blood pressure, and if necessary, improve the 24-hour ambulatory blood pressure monitoring to assist in the definitive diagnosis. 2. Mental tension: when the sympathetic nervous system is excited by mental tension, the feeling of blood rushing to the head will also occur, and it can be improved after relaxation. If the above symptoms occur frequently, it is recommended to consult the hospital in time to improve the anxiety and depression assessment scale and other related examinations, so as to make a clear diagnosis and timely treatment. Regardless of the above reasons for the feeling of blood rushing to your head when you close your eyes at night, you need to closely observe the changes in your own situation, and it is recommended that you consult a doctor in a timely manner to make a clear diagnosis and avoid delays in your condition.
