Drinking alcohol before bedtime is not good for the body, a small amount of alcohol for some more sensitive patients may help sleep, but most patients will instead have insomnia, this is because alcohol in small doses on the nerve excitatory effect will lead to consciousness to stay awake, in larger doses only when there is an inhibitory effect on the symptoms of sleep, and long-term alcohol consumption will have significant damage to health, especially the cardiovascular and cerebrovascular system, alcohol Alcohol can damage blood vessels. If the blood vessel wall is damaged, atherosclerosis and vitreous changes will occur, and atheromatous plaques will easily form in the damaged area, leading to secondary stenosis and poor blood flow, and plaque dislodgement can lead to obstruction of the distal blood vessels causing cerebral infarction or myocardial infarction, so long-term alcohol consumption is an independent risk factor for cardiovascular and cerebrovascular diseases, and it is recommended to quit.
