 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.

How safe and effective are contact lenses?

There is a growing tendency to wear contact lenses when vision is impaired. It is usually placed directly on the upper part of the eye and is a means of improving the eyesight. On the one hand, it solves the problem of vision, on the other hand, the color of the pupil of the eye can be shown as per one's wish. This is a good alternative to glasses. But it also has its disadvantages.

Dryness due to salt

Some people who wear contact lenses often complain of rough eyes in the evening. This is because the contact lenses are actually dry.

Due to the natural tears in the eyes, the lens stays in contact with salt throughout the day. As much as tears come out of the eyes naturally, some salt sticks to the lens. Some salts are good for the eyes but too much salt is not good.

When you cry, the salt goes away

Everyone knows that tears contain salt, but you are surprised to learn that tears that come out of your eyes when you cry are less salty than tears that stay in your eyes.

So when you cry, it affects the balance of salt in the pupil of the eye. When you cry, your contact lenses become so salty that you may find it strange.

New technology lens easier

After various comments about the lens in the early stages, it was extensively researched and the lens was improved. The lens is the first of its kind to have three letters.

The hydrophilic surface gel is applied on the front and back of the sheet between the silicon hydrogels. It is much more soluble than a conventional single-lens lens. This lens gives a lot of moisture to the pupils of the eyes and it is very effective.

Lenses worn daily are good

There are many types of contact lenses. The main ones are daily, once in two weeks, or once in a month. Generally, people choose lenses that can be worn for a long time.

However, lenses that are taken off daily are better. It is the safest. This lens also protects against bacteria for a long time.

Clean properly

People are often worried about the price of the lens, but if you add the price of the lens cleaning solution and other things to it, then the price of daily lenses and long-lasting lenses is the same.

Lenses worn daily are also effective for people who wear lenses regularly because the lenses cannot be kept in a solution for a long time.

Lenses that can be worn at night

This is likely to happen in the future. After sleeping at night wearing lenses, a person's vision should be completely normal by morning. Corneal resection arthroscopy has been used for many years.

Ortho-K lenses fix the cornea overnight. The cornea stays the same size throughout the day. This procedure is good for children and adolescents whose eyesight is constantly deteriorating. Those who do not want to wear glasses and who have mild myopia.

Lenses better than LASIK surgery

Some people decide to have a LASIK operation because they are tired of wearing lenses. However, it also has some disadvantages. The effect of LASIK cannot be reversed.

If you have a problem with the lens, you can take it off. However, many times after LASIK, there is a permanent problem of dry eyes, night vision problems, and infections.

Hard contact lenses for anxious people

First of all, the contact lens hard contact is really very good. It is the only lens of its kind that fixes any problem on the surface of the eye such as blemishes or injuries.

Hard lenses do not make direct contact with the eye, so wearing this lens causes tears to fall between the lens and the eye. This helps in removing the vision defects caused by the lack of tears on the surface of the eyes.

 The first contact lens was made of glass

Contact lenses were originally designed for people with impaired vision. Lenses were not used at that time for people with poor eyesight.

This is about the end of the 19th century. The lenses were made of glass and then applied to the eyes with the help of animal jelly so that people could regain their sight. Doctors later realized that with the help of this technology, even the visually impaired can be treated.

 Affected by contact lens telescope

Although contact lenses originated in the 19th century, they gained immense popularity only in the 20th century.

Astronaut William Herschel and his son John William Herschel were experts in grinding telescope lenses. Jon discovered that if the same lens was ground a little, it could enhance human vision.
