Alcohol produces acetaldehyde, a carcinogen. [사진=게티이미지뱅크]Drinking too much alcohol can leave you with a severe headache and constant anxiety the next day. This phenomenon is called ‘hangxiety’. Experts say that this phenomenon also has physiological factors.

David Nutt, an author and neuropsychopharmacologist who specializes in the effects of alcohol on the brain at Imperial College London, told National Geographic, “If you drink small amounts, you may feel confused. However, if you drink a lot, you may feel anxious,” he said.

According to the Cleveland Clinic, gamma-aminobutyric acid (GABA), a neurotransmitter in the brain, can reduce stress and anxiety by calming the central nervous system. However, alcohol also temporarily has the same effect by binding to the protein that GABA affects.

Because alcohol mimics the effects of GABA, the body produces less GABA and, as a result, does not have enough of the chemical to reduce anxiety the day after drinking. “This is why when people drink alcohol, they feel more relaxed, less inhibited, and less cautious,” Yale School of Medicine professor Stephen Holt told National Geographic.

Additionally, increased GABA activity while drinking reduces the effectiveness of glutamate, a stimulatory neurotransmitter that increases energy. This causes the brain to produce excessive glutamate. “It can take several months for the body to properly regulate the GABA-glutamate system,” Professor Holt said. “People who drink alcohol on a daily basis may show symptoms of dysregulation before their first drink because their brains have been trained to anticipate alcohol consumption and naturally lower GABA levels,” Nutt said.

Alcohol can be considered a poison because it breaks down in the liver and produces acetaldehyde, a carcinogen that can cause stomach upsets, headaches, and anxiety.

[사진=게티이미지뱅크]Recently, the number of couples who sleep in separate rooms is increasing. The number of couples who do not share a separate room but are considering changing their double bed to a single bed is also increasing.

When a couple shares a bed, they can feel secure and comfortable, but the situation changes if their spouse snores or keeps tossing and turning while sleeping. Concerns are growing that it will be difficult to sleep well.

According to a recent paper published in the academic journal Current Biology, rats that slept together showed that although they slept together and woke up together, their sleep quality overall decreased.

Researchers led by Ada Evan Rothschild, a professor of psychology at the University of Michigan, studied the effects of co-sleeping on sleep quality in rats. By monitoring brain activity during sleep, the researchers were able to track the rats’ sleep intensity and sleep-wake cycle.

The study found that mice that sleep together tend to fall asleep and wake up at the same time, synchronizing the intensity of their non-rapid eye movement (REM) sleep. REM sleep is a concept that encompasses three stages of sleep, including deep sleep, which is essential for physical recovery and memory strengthening. However, it has also been found that synchronization in sleep stages fragments sleep and reduces overall sleep quality.

But despite these difficulties, the rats tried to find other rats they could sleep with. The rats were willing to give up their preferred sleeping location and environment to sleep next to their fellow rats.

Another interesting finding was that REM sleep was synchronized between male sibling rats sleeping together, but not between female or unfamiliar rats. The exact reason for this gender difference is unclear, but the researchers hypothesize that the degree of synchronization may vary depending on how safe one feels.

“The findings clearly show that not everyone responds to co-sleeping in the same way,” the researchers said. “If the benefits of comfort and safety outweigh the potential disruption, co-sleeping may be a good choice. However, if you wake up every hour to the sound of snoring next to your ear, it may be a good idea to use a separate bed.”
