With the holiday season high, there is festive cheer, family gatherings and also an undeniable increases in alcohol consumption that fills the air. Christmas and New Year's Eve celebrations to spring break and bachelor parties and sporting events that bring together huge crowds for celebrations mean that drinking becomes synonymous with partying. But behind the revelry lies a much darker behavior: high-intensity drinking.

Alcohol is the most widely used substance in the United States; it has been reported that 84% of adults aged 18 and older reported lifetime use. Moderate drinking is socially acceptable, but high-intensity drinking is an alarming trend. The behavior of consuming eight or more drinks over a few hours for women and 10 or more for men exceeds binge drinking and significantly increases risk for harm.

High-intensity drinking is far from being just a mere passing concern; it is instead a public health crisis. The burden is even greater as 29 million people in the United States suffer from alcohol use disorder. That has caused over 140,000 deaths annually while accounting for 200,000 hospitalizations and 7.4% of visits to emergency departments in the United States. However, only 7.6% of these affected get treated, thus forming a glaring gap in handling this concern.

What Is High-Intensity Drinking?

High-intensity drinking is a dangerous escalation from traditional binge drinking, characterized by consuming double or triple the standard binge amounts. While binge drinking involves four or more drinks for women and five or more for men, high-intensity drinkers often surpass these levels, leading to blood alcohol concentrations (BAC) exceeding 0.2%—a level that significantly impairs judgment and motor skills.

According to Dr. George Koob, the director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), high-intensity drinking is one of the factors that intensify the risks of injuries, overdose, and death. It is also very highly associated with the onset of AUD, since the chance of addiction increases with increased alcohol consumption per occasion.

Blackouts and Memory Loss Risks

One of the most troubling consequences of high-intensity drinking is alcohol-induced blackouts, periods of amnesia where individuals may appear functional but are incapable of forming memories. Blackouts occur when alcohol disrupts the hippocampus, the brain region responsible for memory formation.

Blackouts are often categorized into two types:

1. Fragmentary Blackouts: Characterized by spotty memory, where recalling certain details can trigger partial recollection.

2. En Bloc Blackouts: Significant amnesia for hours, wherein no memory is created at all, even if tried to be recalled.

Aside from memory loss, intense binge drinking is linked with poor decision-making, violence, injury, and conflicts in personal relationships.

Why Holidays and Special Events Are Hotbeds for Excessive Drinking

Holidays and celebrations create the perfect storm for high-intensity drinking. According to research, adults drink nearly double the amount of alcohol during holidays like Christmas and New Year's Eve than they do at any other time of the year. It is during these periods of social gathering, holiday stress, and seasonal sadness that people drink in excess.

For college students, experiences like spring break and 21st birthdays increase the danger. Some studies indicate that students, especially those who travel with buddies to spring break, indulge in more alcohol and make more serious decisions than any student who remains at home or goes with their family to other destinations. Sporting events are, too, notorious for promoting drunk consumption, especially among male customers. Alcohol consumption usually goes high during Super Bowl Sunday, thus leading to games day violence and arrests.

Consequences of Heavy Intensity Drinking

High-intensity drinking impacts not only physical health and mental well-being but also social relationships.

Acute Risks

- Alcohol poisoning

- Severe dehydration and electrolyte imbalances

- Hypoglycemia

- Risky sexual behavior

- Injuries and accidents

Chronic Risks

- Liver damage, alcoholic hepatitis, and cirrhosis

- Cardiovascular diseases such as arrhythmias and cardiomyopathy

- Neurological damage, including memory deficits and blackouts

- Progression to alcohol dependence or AUD

Psychological Impact

High-intensity drinking is strongly linked with increased risks of depression, anxiety, and suicidal ideation. Poor decision-making during episodes can lead to long-lasting consequences, including damaged academic, professional, or personal outcomes.

How to Address the Problem

Combating high-intensity drinking requires education, early intervention, and accessible treatment options. The NIAAA has defined high-intensity drinking to be distinct from binge drinking and has called for targeted approaches to decline prevalence and associated harms.

One promising treatment option is naltrexone, which a medication helps control alcohol cravings. Encouraging in preliminary evidence, more extensive clinical trials will be necessary to ascertain its efficacy more specifically in high-intensity drinkers.

As we head into the holiday season and other special occasions, it is important to heighten awareness of the dangers of high-intensity drinking. A good understanding of long-term consequences and seeking help when alcohol-related issues arise can be the difference between life and death. Celebrations should be about joy and connection, not about the gateway to harm.

If you or someone you know drinks at dangerous levels or have an alcohol use disorder, there is help available. Remember, for suspected cases of alcohol poisoning, dial 911. In this way, we can foster healthier relationships with alcohol and create safer environments for everyone.

Clear vision does not always mean that the eyes are healthy. Diabetes can damage the retina the sensitive layer at the back of the eye long before a person notices any change in eyesight.

This happens because high blood sugar can weaken the blood vessels that supply the retina causing them to leak fluid or blood.

What happens as retinopathy progresses?

Diabetic retinopathy is a complication in which high blood sugar damages the blood vessels. In the stages these vessels may swell or develop small areas of bleeding without affecting vision.

As the condition advances, reduced blood supply can cause abnormal new blood vessels to grow. These vessels are fragile. May bleed into the vitreous the clear gel inside the eye. In some cases, scar tissue can pull the retina away from its normal position leading to retinal detachment and potentially permanent vision loss.

How diabetes affects central vision

Diabetes can also affect the macula, the part of the retina responsible for sharp detailed vision. When fluid builds up in this area it can cause macular oedema and gradually affect the quality of vision.

It may lead to:

• Distorted central vision
• Difficulty reading or recognising faces
• Problems with activities that require clear detailed vision, such as driving

Diabetic macular oedema can occur at different stages of diabetic retinopathy and does not always cause symptoms in the early stages.

Who is at risk?

The likelihood of eye damage increases with the duration of diabetes and poor blood sugar control. High blood pressure, abnormal cholesterol levels and kidney disease can further increase the risk.

Women with diabetes may also need monitoring during pregnancy as hormonal and blood sugar changes can worsen existing retinal disease.

Why regular eye examinations matter

On World Sight Day, doctors recommend that a routine eyesight test may not detect damage to the retina. People with diabetes should therefore undergo an eye examination, including a dilated retinal examination at intervals recommended by their ophthalmologist.

Keeping blood sugar, blood pressure and cholesterol, under control can help reduce the risk of complications. If damage is detected treatment may include eye injections, laser therapy or surgery depending on its severity.

Diabetic eye disease can often be managed effectively when identified early. Regular retinal examinations remain important when a person can see clearly as changes may develop before symptoms appear.

Menopause is a natural stage of aging that ends menstruation and reproductive function. It usually occurs between ages 45 and 55.

But growing interest in extending the reproductive years has raised a question: Can menopause be delayed, and would doing so actually benefit women's health?

Longevity influencer Kayla Barnes-Lentz, in her mid-30s, recently told Business Insider that she is trying to delay menopause until 60 using lifestyle changes and experimental treatments.

Can Menopause Be Delayed?

Scientists are studying ways to slow ovarian aging, including ovarian tissue freezing and drugs such as rapamycin.

Early human research suggests rapamycin may slow ovarian aging by around 20%. However, evidence remains limited, and the drug is not FDA-approved for delaying menopause. Its use for this purpose is off-label.

The 2024 Research by Dr. Kutluk Oktay at Yale School of Medicine has also explored whether menopause could eventually be postponed or prevented by preserving ovarian function.

But delaying menopause is not necessarily an all-round health benefit. Longer estrogen exposure may support bone, heart and brain health, while potentially increasing the risk of some hormone-sensitive cancers.

What Are The Risks Of Early Menopause?

Menopause around age 45 or younger can affect several aspects of health as estrogen levels fall.

• Bones: Faster bone loss and higher osteoporosis risk.
• Heart: Changes in blood vessels and cholesterol may increase cardiovascular risk.
• Brain: Hormonal changes can affect memory and cognition.
• Sexual health: Vaginal dryness and reduced lubrication can cause discomfort.
• Urinary health: Lower estrogen can contribute to urinary symptoms and incontinence.

Is Later Menopause Healthier?

Menopause at 55 or older means longer exposure to estrogen and has been associated with some benefits, including better bone and cardiovascular health.

But the picture is not straightforward. Longer estrogen exposure has also been linked to a higher risk of breast, endometrial and ovarian cancers. So, later menopause should not automatically be considered healthier.

Can HRT Delay Menopause?

No. Hormone replacement therapy treats menopause symptoms but does not stop or postpone menopause.

It can help with hot flashes, sleep problems and vaginal dryness and may benefit some women at risk of bone loss. HRT can contain estrogen alone or estrogen with progesterone.

Its risks and benefits depend on factors such as age, timing, formulation, dose and duration. For appropriate women, the benefit-risk balance is generally more favorable when treatment begins before age 60 or within 10 years of menopause.

Can lifestyle delay menopause?

Genetics play a major role in determining when menopause occurs, and there is no lifestyle change proven to reliably postpone it.

Some factors have been linked with later menopause or a lower risk of early menopause:

• Breastfeeding: Longer breastfeeding has been associated with a lower risk of early menopause.
• Exercise: Supports overall health, although evidence that it directly delays menopause is limited.
• Not smoking: Smoking is linked to earlier menopause.
• Healthy diet: Some research links diets rich in antioxidants and omega-3 fatty acids with later menopause.

These habits cannot guarantee a later menopause but can support overall health through midlife.

For now, treatments specifically designed to delay natural menopause remain experimental. There is no established method that can reliably and safely postpone menopause in healthy women.

The suspected plague situation in Russia has reportedly claimed another life, fueling fears of a potential outbreak. However, Russia has not confirmed that either death was caused by plague, and investigations into the cases are ongoing.

India, which has witnessed plague outbreaks in the past, including the 1994 Surat outbreak and a pneumonic plague outbreak in Himachal Pradesh in 2002, also has rodent populations that can serve as reservoirs for plague. But does the situation in Russia pose a risk to India if plague is eventually confirmed?

To understand the potential risk to India, HealthandMe spoke to two experts with experience investigating plague outbreaks in India.

Plague From Test-Tube Exposure?

The death of a 28-year-old laboratory worker in Russia’s Irkutsk region has raised concerns about possible plague exposure. Reports said she may have accidentally broken a test tube containing Yersinia pestis, the bacterium causing plague, while collecting samples. However, Russian authorities have not confirmed plague and said she died of pneumonia of unknown cause.

Dr NK Ganguly, former Director General of the Indian Council of Medical Research (ICMR) told HealthandMe that the case has not been established as plague and questioned whether a test-tube exposure could explain plague pneumonia.

“Actually, the case in Russia has not been proven to be plague. It has been reported as a case of unknown cause and undiagnosed pneumonia. They have been investigating plague among about 2,000 people in the vicinity, as well as among people in the laboratory. So, they have not confirmed it as a plague case. And from a test tube exposure, it is difficult to have plague pneumonia.”

Unconfirmed reports have also claimed another death linked to the same laboratory, but this has not been independently verified.

Dr Ganguly was one of the people who investigated the 1994 plague outbreak in Maharashtra’s Beed district.

Should India Be Concerned?

There is currently no indication that the situation in Russia poses a significant pandemic risk to India.

Dr Ganguly said there is no reason for India to be very concerned about the Russian situation, particularly because plague has not been confirmed.

“So from the Russian plague, there is no, we need not be very worried. Firstly, they have not reported it as plague. It might be plague, but they have not reported it as plague.”

The WHO has also assessed the risk to the wider population as low. WHO spokesperson Christian Lindmeier said the initial assessment based on available information put the risk at moderate to low for Irkutsk, low for Russia as a whole and very low for the WHO European Region.

How Does Plague Spread?

Plague is caused by the bacterium Yersinia pestis and is primarily associated with rodents and their fleas. It can occur in different forms, including bubonic, septicemic and pneumonic plague. Russia is suspected to have pneumonic plague.

Dr Amitabh Banerjee, who investigated the Himachal Pradesh plague outbreak in 2002, said plague does not typically spread rapidly from person to person.

“So it's not a very quick transmission, particularly person to person. But plague is a disease which cannot be eradicated because it is in wildlife, it is in rodents and all. So the only thing is hygiene and, with modern antibiotics, there should not be any panic,” he told HealthandMe.

Banerjee also noted that pneumonic plague can be severe, while bubonic plague does not typically spread easily from person to person.

“So pneumonic plague can be very deadly particularly pneumonic plague and that will be localized pandemic it is not possible because those persons will be very sick, they cannot move out or not and bubonic plague will not transmit very easily from person to person and both are treatable…”

How Should India Prepare?

While Dr Ganguly said there is no immediate reason for India to be worried about the Russian situation, he stressed the importance of continued surveillance of rodents and other animals, particularly where wildlife and human habitation overlap.

“So the main thing is that go on doing surveillance in the rats and other, in the vicinity of where the forest and the human habitat march. And whenever you find any activity, then take preventive precaution.”
