 Why do people get headaches and red eyes after drinking alcohol?

A headache after drinking alcohol is a common problem, which people know as a ‘hangover’. That is why most people say they have a hangover after drinking too much alcohol.

According to an article based on a study published on the American website National Institute of Alcohol Abuse and Alcoholism (NIAAA), a hangover refers to the symptoms that appear as a result of drinking too much alcohol.

What science says is that when we drink too much alcohol, we experience a hangover, or when our head starts to hurt, we feel dizzy, and by that time there is no alcohol left in our body.

Why do we get headaches after drinking alcohol?

Dr. Rajiv Jha says that headaches are common after drinking alcohol. ‘Alcohol itself is a bad drink, which keeps the body in its grip for a long time,’ says Dr. Jha, ‘A person who drinks alcohol can have a hangover for two days. That is why people who drink alcohol experience headaches, body aches, laziness, and weakness.

After drinking alcohol, there is an immediate and another long-term side effect. Headache is an immediate side effect, says neurologist Sunilram Koirala. ‘Alcohol is a substance that mixes with the blood as soon as it reaches the stomach. Its full effect starts to be seen within 10 minutes to one to two hours,’ says Dr. Koirala. ‘Our brain needs to be informed by the nervous system. Various chemicals are being produced there. Alcohol blocks them and changes the brain’s information system.’

That is why people who drink alcohol start to experience problems such as being unable to think, unable to make decisions, slurred speech, and unable to remember, says Koirala. He says, ‘Alcohol overstimulates our nervous system and brain, making it almost like thinking.’

Alcohol is made from ethanol. Ethanol is a type of poison found in alcoholic beverages. Enzymes in our body break it down and convert it into various other chemicals. The most important of these is acetaldehyde. The main cause of hangovers is this acetaldehyde, says Dr. Saroj Kumar Suwal, a specialist in orthopedics and neurology.

According to Dr. Suwal, when alcohol is broken down in our liver, a more toxic chemical called acetaldehyde is formed. A substance called glutathione tries to make acetaldehyde less toxic. But when you drink a lot of alcohol, the level of glutathione decreases and acetaldehyde starts accumulating in large quantities in the body. It is broken down further and converted by enzymes into another chemical, acetate.

This acetate chemical is converted into fatty acids and water. Acetaldehyde enters the bloodstream and is distributed around the body. It damages healthy cells and causes hangovers, including dizziness.

Drinking too much alcohol can lower blood sugar levels, which can lead to weakness, lightheadedness, and fatigue, says Dr. Suwal. “After drinking alcohol, you urinate more than usual,” says Dr. Suwal. “In this case, not drinking enough water can lead to dehydration. Dehydration can trigger headaches and migraines in people with migraines. Also, people with migraines are more likely to have hangovers after drinking alcohol.”

Alcohol consumption also affects sleep. Most people drink alcohol late at night. As a result, they do not get enough sleep. This is also why they experience fatigue and headaches, said Suwal.

Why do eyes turn red after drinking alcohol?

Alcohol has different effects on each person. Alcohol consumption slows down the speed of communication between neurotransmitters in the brain. This can delay the brain and eye receiving messages. It weakens the coordination of the eye muscles. Due to which excessive alcohol consumption can cause problems such as dry eyes and redness, says Dr. Koirala.

When the effects of alcohol increase, the amount of sugar in the blood decreases. Koirala says that due to the lower amount of sugar in the blood than required, the eyes become blurry and vision becomes weak and the eyes become red.

Prevention methods

You can find a lot of information on social media about ways to reduce alcohol hangover. However, Dr. Koirala says that none of the methods have been scientifically proven to be effective.

‘There is no medicine to get rid of a hangover,’ says Dr. Koirala, ‘it starts to go away on its own after some time. You have to wait for the person’s body to digest alcohol, eliminate toxins from the body, rehydrate, repair the cells that have been burned by alcohol, and restore normal brain activity.’

To reduce the effects of a hangover, you need to reduce the amount of alcohol. He says that the more you reduce the amount, the less hangover you will have.

Don't drink alcohol under the pretext of cold, it can cause nerve damage

The human spinal cord is made up of many bones. There is a black disc in the middle of each bone. A type of fluid disc is like nauni ghee. If there is a broken arm or leg due to an accident or if there is a problem in moving the bone, the disc protrudes from between the two bones and squeezes the nerve. In common parlance, this is called an intervertebral disc prolapse.

Alcohol makes sanitizer

As the coronavirus infection is spreading in the world, the panic has also increased in Nepal. People are increasingly using masks and sanitizers to prevent infections. Due to which the market demand is increasing. There are allegations that there is a lack of it in the market due to some black market as an opportunity to make money. Meanwhile, Lalitpur Metropolitan City has trained the locals to make masks and sanitizers. The metropolis has conducted training to make sanitizer from alcohol to prevent a shortage in the market.

The metropolis has imparted training on making sanitizer from alcohol with the technical assistance of the Nepal Academy of Science and Technology (NAST). Sixty representatives from 29 wards of the city participated in the training which started last Sunday. The metropolis had earlier given training in making masks. "Initially, we trained to make masks by understanding the lack of market," said Harishchandra Ghimire, a senior engineer at the metropolis.

Ghimire said that the participants were taught the whole method of making sanitizer from home-made liquor. Nast spokesperson Suresh Kumar Dhungel said that they have been trained to prepare local manpower for the production as sanitizers can be made through the use of home-made liquor.

After the training, it will be very easy to make sanitizer by processing home-made liquor, says Sajan Lal Syaula, head trainer and senior scientist of Nast. According to Syaula, domestic alcohol contains 35 to 42 percent ethanol. About 75 to 80 percent ethylene is needed to kill the virus. "We have learned how to increase the amount of ethanol in alcohol," he said. "We have learned how to increase the amount of ethanol in alcohol in the way recommended by the World Health Organization."

What is a sanitizer?

Sanitizer is a chemical that usually kills germs by cleaning. We use soap to clean our hands and disinfectants to clean the floor. Antiseptics are used to treat the body's living organisms, according to Scientific Syaula. All chemicals have their own method of cleaning. "When we clean our hands, the soap washes away the dirt and doesn't kill the germs," ​​says Syaula. "We can't use disinfectants in the body, they are used to kill bacteria." Therefore sanitizer is antiseptic.

Let's not put sanitizer in the eyes

What can be used to make sanitizer?

Sanitizers can be made in thousands of ways. However, only sanitizers made from alcohol are considered effective. Alcohol also falls into the category of chemicals. Alcohol contains chemicals including methanol, ethanol, butanol. The World Health Organization recommends making sanitizers from methanol, ethanol, and butanol. We have learned to make sanitizer using ethanol found in homebrew.

When to use it?

It can be used in any situation. It doesn't matter if you use a sanitizer to hold a newborn baby. It is used to prevent infection from one person to another. They also use sanitizer in and out of the hospital's operating theater. It is always useful to avoid any infection.

Does too much use affect or not?

Does not This is because alcohol does not stay on the skin for long. It flies away in an instant. Being in the body does not harm. There is nothing to be afraid of. But, it should not be overlooked.
