Drinking alcohol when your head is groggy all day and night may be associated with psychiatric factors, insufficient blood supply to the brain, and alcohol dependence syndrome. However, this effect can not be sustained, and drinking itself is not conducive to good health, can not be used as a treatment method. 1. Psychological factors: Long-term mental tension and anxiety can lead to dizziness, and some people’s mental tension can be relieved after drinking alcohol so that their dizziness can be improved. 2. Insufficient blood supply to the brain: commonly found in patients with cerebral arteriosclerosis, due to the narrowing of the blood vessel lumen and thickening of the blood vessel wall, which leads to the obstruction of blood flow, resulting in insufficient blood supply to the brain, resulting in dysfunctions of the brain tissue, which can be manifested as symptoms of dizziness and lightheadedness. Drinking alcohol can briefly improve blood supply to the brain and relieve dizziness because of its vasodilating effect. 3. Alcohol Dependence Syndrome: seen in long-term drinkers, various uncomfortable symptoms will appear after quitting drinking, such as tremor, restlessness, dizziness, etc., which can be relieved after drinking. It is recommended that patients clarify the specific causes of dizziness and receive symptomatic treatment as soon as possible, and do not use alcohol to alleviate the symptoms.
