A hangover occurs for several reasons. The first is that alcohol causes severe dehydration (normal, it is very diuretic). It is this dehydration that causes headaches, dry mouth and difficulty concentrating after particularly drunken evenings. In addition, alcohol is high in sugar: as it encourages the body to produce insulin, it causes our blood sugar levels to drop… which also causes unbearable headaches that are hard to get over. rid.
But those who are least prone to hangovers are mostly those who are not very sensitive to the effects of acetaldehyde, the toxic substance produced when alcohol is metabolized by the liver. Lucky you, you might think. Not quite. Because if their metabolism does not feel the effects of alcohol so openly, that does not mean that these “lucky little guys” are immune to its long-term effects .
“On the contrary, people who have a hangover tolerance tend to drink more excessively, since their body does not send them warning signals. However, the more alcohol we consume during his life, the more increases the risk of many pathologies: cancers, diseases of the liver (cirrhosis) and pancreas, cardiovascular disorders, arterial hypertension, diseases of the nervous system and psychic disorders (anxiety, depression, behavioral disorders)” explains Dr Sarah Jarvis, Medical Adviser to the Alcohol Prevention Association of Great Britain.
The simplest thing, on festive evenings, is therefore to drink “in moderation”. But if despite everything, the next morning, you have a headache, apply our anti-excess SOS plan.
