The end of the year comes and the toasts multiply. But after several "chin cheeks", many of us damaged so much hullabaloo.
Strenuous headache, stomach ailment, fatigue and flexibility are some symptoms of hangover.
However, it does not happen to everyone: lucky people do not continue drinking the next day.
In fact, some research suggests that 25% of those who drink excessively to avoid excessive consumption.
- Months and years of loss of life if you drink alcohol every day
- Why do some people remember the unfortunate neglected (and do they think about health)?
Ava Karuso is one of those people. He says that Australia's 25-year-old friends can snuggle with friends, drink with them and be healthy the next day (but not with their friends).
Ava wanted to know this and why he asked Rutherford and Fry's "The curious houses of Rutherford and Fry" BBC radio show, Adam Rutherford and Hannah Fry scientists investigating everyday mysteries sent by the public.
"Why do some people suffer from drinking one night and others (like me) do not feel the same?" The young Australian asked.
To find out, Rutherford and Fry started asking for a specialist who causes allergic effects on our body.
"When you drink alcoholic beverages, it can feel effects between 10 and 90 minutes, but alcohol is very effective in your blood flow," said Sally Adams, Ph.D., from the University of England, at the University of Bath.
"(Alcohol) crosses the blood brain barrier and basically interacts with all the neurotransmitters in the brain," said the expert, one of the few scientists in the world.
Neurotransmitters are molecules that bind the brain and nerve cells and cause alcohol to be transmitted.
"This explains why the rare effects are not good to talk or have fun," said Adams. We do not think clearly and we act fairly.
But the consequences of alcohol on our brain have more dizziness. To better understand respect, we need to concentrate another organ: liver, alcohol processes.
"When you drink alcohol, you want to eliminate your body, that you have an alkohol dehydrogenase, a liver enzyme," said Andrea Sellak, from University College London, to this program.
It removes hydrogen from the enzyme from the alcohol and becomes something called aketaldehyde.
"Acetaldehyde is very toxic," said Sella. Many experts think the main cause of hangovers.
But if we process alcoholically in this way, why only feel the consequences of a rescue?
Sella linked the liver dehydrogenase with enzyme to the liver.
"The speed of alcohol treatment depends on your system's alcohol dehydrogenase," he explained.
This factor (your amount of enzymes that metabolize your liver alcohol) determines your genetics.
"They have different amounts of alcohol from different people," said Sella.
"If you have the cost of eliminating the aketaldehyde and accumulate the level of this compound, you will feel very bad," he said.
This is likely to be the key to answering Ava's question.
Maybe he cooks genetically better than alcohol and does it with his friends and explains tolerance.
But there are other possible explanations.
For example, it can do it with your immune system.
"We still do not know exactly why people feel so bad during hangover, but the theory is best because the response is immune," says Adam Rogers, author of the book "Evidence: Alcohol Sciences."
Experts believe that excess alcohol creates an immune reaction that causes certain substances that release inflammation and causes many symptoms.
"If you have respected, you know it's like a flu," said Rogers. "You feel ill, like an infection."
So you know. If you have a drink in New Year's Eve and Christmas, the liver and the immune system may be considered a tide.
Of course, if you are not like Ava.
