What causes headaches after drinking beer?

Alcohol is one of the most common drinks in people's daily life. Of course, no matter what kind of alcohol it is, the main ingredient is ethanol, but the content of ethanol varies with the type of alcohol. Many men get a headache after drinking a little beer. What's going on?

Why do I get a headache after drinking?

1. Headache after drinking alcohol -- caused by alcohol oil:

Whether it is brewed wine or distilled wine, there are trace amounts of alcohol oils, which are also the factors that cause dizziness after drinking.

2. Amine stimulation:

Beer, rice wine and fruit wine are rich in amines, which are catecholamines that stimulate the sympathetic nerve endings to release adrenaline. Adrenaline has the effect of constricting blood vessels and increasing blood pressure, thereby causing headaches.

3. Insufficient blood supply to the brain:

Drinking alcohol can reduce cerebral blood flow, and the reduction in cerebral blood flow can cause the accumulation of lactic acid, oxygen ions, methyl ions, adenosine, prostaglandins and catecholamines in the brain. These substances are pain-causing substances themselves, and these substances can also cause cerebral vasodilation.

Notes

Honey water can cure headaches after drinking. Honey contains a special fructose that can promote the decomposition and absorption of alcohol and relieve headache symptoms, especially headaches caused by red wine.
