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.

Rubbing your eyes is a common habit, often triggered by itching, dryness or tiredness. However, frequent and vigorous rubbing can damage the cornea and increase the risk of keratoconus, a progressive condition that causes it to thin and bulge outward, experts warn.

World Keratoconus Day is observed every year on November 10 to raise awareness about the condition.

Early diagnosis is important to slow its progression. Frequent changes in spectacle prescriptions or deteriorating vision should prompt an eye examination.

Why Should You Avoid Rubbing Your Eyes?

Frequent or aggressive eye rubbing can put mechanical stress on the cornea, potentially weakening its structure and worsening existing eye conditions.

Speaking to HealthandMe, Dr Janhvi Mehta, Consultant Ophthalmologist, Jaslok Hospital and Research Centre, Mumbai, said, "Frequent or vigorous eye rubbing can damage the cornea, particularly by contributing to keratoconus. It can also cause corneal epithelial injury and worsen existing ocular allergy."

Repeated rubbing can:

• Contribute to corneal thinning and biomechanical weakening.
• Accelerate keratoconus in susceptible individuals.
• Cause corneal abrasions and increase the risk of infection.

Dr Mahipal Singh Sachdev, Chairman and Managing Director, Centre for Sight Group of Hospitals, explained that excessive rubbing puts pressure on the cornea and can damage its collagen structure.

"The cornea might become thinner than usual or its shape may become uneven, leading to impaired vision. Hence, people should avoid the habit of rubbing their eyes," he told HealthandMe.

Why Are Children More At Risk?

Children with allergies, especially allergic conjunctivitis, may be more vulnerable to keratoconus because of frequent eye rubbing.

Allergies can cause persistent itching, redness, watering, and discomfort, encouraging children to rub their eyes repeatedly. The resulting mechanical stress may contribute to the development or progression of keratoconus in susceptible individuals.

The experts urged parents to watch for excessive rubbing and changes in their children's vision. Timely allergy treatment and regular eye examinations can help identify potential problems early.

Other risk factors for keratoconus include:

• Vernal keratoconjunctivitis (VKC)
• Atopic eye disease
• Family history of keratoconus
• Genetic predisposition
• Certain connective tissue disorders

However, not everyone who frequently rubs their eyes develops keratoconus.

Why Is Keratoconus Often Diagnosed Late?

Dr Janhvi noted that keratoconus commonly begins during adolescence or early adulthood but may remain undiagnosed until vision deteriorates.

Its early symptoms can resemble common refractive errors such as myopia. Children and young adults may experience mild blurring or require frequent changes in their spectacle prescriptions, which can be mistaken for routine vision changes.

The condition can also progress gradually and initially affect only one eye, making changes harder to recognise. Routine eye examinations may not always detect early keratoconus without specialised corneal assessment, Dr. Mahipal said.

Warning signs to watch for include:

• Increasing myopia
• Progressive or irregular astigmatism
• Frequent changes in spectacle prescriptions
• Reduced visual clarity despite corrective lenses
• Ghosting, glare or double vision in one eye
• Difficulty driving at night

Increasing astigmatism despite repeated spectacle corrections is an important warning sign that warrants further evaluation.

How Can You Prevent Corneal Damage?

Preventing excessive eye rubbing and managing its underlying causes can help reduce avoidable stress on the cornea.

1. Break the eye-rubbing habit

• Avoid pressing or massaging closed eyelids.
• Use a cold compress when your eyes itch.
• Avoid rubbing your eyes even through a towel or handkerchief.
• Keep children's fingernails short to minimise accidental injury.

2. Treat underlying allergies

If itching triggers eye rubbing, consult an ophthalmologist about appropriate treatment. Options may include topical antihistamine or mast-cell stabiliser drops, such as olopatadine or ketotifen.

Other measures include:

• Using preservative-free artificial tears for irritation
• Treating associated blepharitis or dry eye
• Avoiding prolonged use of topical steroid drops without medical supervision

3. Reduce exposure to environmental triggers

• Avoid dust, smoke and known allergens
• Wear protective glasses outdoors
• Avoid direct airflow from air conditioners.

Come Saturday morning, many people have just one thing on their mind: catching up on sleep. After a week of early mornings, office deadlines, late-night screen time and household responsibilities, the weekend feels like the perfect opportunity to stay in bed for a few extra hours. Some people even sleep until noon, believing that the extra rest will make up for all those late nights. But is it really possible to undo five days of poor sleep in just two days?

Unfortunately, the brain doesn't work that way. Sleeping longer over the weekend can certainly help you feel less tired, but it cannot completely compensate for a week of inadequate sleep.

Sleep is much more than physical rest. It is when the brain gets down to some of its most important work. Memories are processed, information gathered during the day is organised, and the brain gets an opportunity to recover from constant activity. When we repeatedly cut short our sleep, these processes can suffer.

Why Do We Feel Better After Sleeping In?

Think about how you feel after several nights of going to bed late. You may find yourself forgetting small things, struggling to concentrate during meetings or becoming unusually irritable over minor issues. These are some of the ways sleep deprivation can affect everyday functioning.

Sleeping for a few extra hours over the weekend can ease some of this fatigue. You may feel more alert and find it easier to concentrate. However, feeling refreshed is not necessarily the same as being fully recovered. Certain effects of repeated sleep restriction, particularly on attention and reaction time, can take longer to resolve.

Can Weekend Lie-ins Disturb Your Sleep Cycle?

There is another side to this weekend habit that people rarely consider. If you sleep at 11 pm during the week but stay awake until 2 or 3 am on Friday and Saturday, your body's internal clock can get disrupted.

This internal timing system, called the circadian rhythm, helps regulate when you feel sleepy and when you wake up. Large changes in sleep timings can make it harder to fall asleep on Sunday night. Before you know it, Monday morning arrives and you are back to feeling exhausted.

It becomes a familiar cycle: insufficient sleep during the week, prolonged sleep on weekends and difficulty getting back into a routine.

What Does Repeated Sleep Deprivation Do To The Brain?

One of the biggest areas affected is memory. Sleep plays an important role in consolidating information, which is why a poor night's sleep can make it harder to remember things or absorb new information the following day.

It can also affect emotional regulation. People who regularly sleep less may become more impatient, anxious or sensitive to everyday stress. Their ability to focus and make decisions may also take a hit.

Persistent sleep deprivation has also been associated with metabolic and cardiovascular problems. It is therefore important not to treat poor sleep as an unavoidable part of a demanding work schedule.

What Is A Healthier Way To Catch Up On Sleep?

Rather than depending on Saturday and Sunday to recover, try making small changes to your routine throughout the week.

• Keep a consistent schedule: Try to go to bed and wake up at roughly the same time every day.
• Don't compromise on sleep duration: Most adults need around seven to nine hours of sleep each night.
• Put your phone away before bedtime: Late-night scrolling can keep the mind stimulated and delay sleep.
• Be mindful of caffeine: That evening cup of coffee may be affecting your ability to fall asleep.
• Step outdoors in the morning: Natural daylight helps regulate the body's sleep-wake cycle.
• Pay attention to persistent tiredness: If you wake up exhausted despite getting enough sleep, speak to a doctor. Sleep disorders such as obstructive sleep apnoea may need to be ruled out.

Your brain needs rest every day, not just when the calendar says it is the weekend. Instead of treating sleep as something you can postpone and recover later, make it a non-negotiable part of your daily routine.

For decades, vaccines have transformed numerous fight against aggressive infectious diseases, saving millions of lives. Still, despite years and years of research proving their effectiveness, there is still significant skepticism surrounding vaccination. One of the most enduring claims is that vaccines, especially the measles, mumps and rubella (MMR) vaccine, can cause autism.

The belief that vaccines can cause autism has been debated for decades, despite a solid body of research failing to establish a link between the two.

In an exclusive interview with HealthandMe on World Immunization Day, Dr. Paul Offit, paediatrician and director of the Vaccine Education Center at Children’s Hospital of Philadelphia and former member of the CDC’s Advisory Committee on Immunization Practices, explained why the vaccine-autism claim is a myth difficult to debunk.

Why Is The Vaccine-Autism Issue Still Debated?

According to Dr Paul Offit, the controversy can be traced back to a 1998 paper that claimed the measles, mumps and rubella (MMR) vaccine caused autism. “I think it was born in that 1998 paper that MMR caused autism,” he said.

He said that the paper did an excellent job at convincing the masses that the adverse events related to vaccines can be long-standing and irreversible, like autism. Offit said the original claim had a lasting effect on public understanding of vaccine safety.

He said, “It’s very hard to unring the bell once you've rung it. I think it's hard to unscare people.”

He said the public-health and academic communities responded by conducting study after study to examine the alleged association. “But vaccines don't cause autism,” Offit said.

He believes that the research conducted after the 1998 paper helped address the concern. He said, “The question has been answered. Most parents of children with autism no longer believe that's the case. So I think that those studies were of value,” he said.

The 1998 paper by Andrew Wakefield and colleagues, which suggested a connection between the MMR vaccine and autism, was later retracted by The Lancet. Subsequent research has not established that MMR vaccination causes autism.

Offit said vaccines had been studied extensively as a possible environmental factor in autism. “Vaccines are probably the best studied environmental factor and that ain't it,” he said.

Dr. Offit said that genetics plays an important role in autism, while several factors related to maternal health and pregnancy have also been associated with the condition. He said, “About 80% of autism is genetic.”

He added, “There are a number of sort of factors regarding maternal health, regarding maternal drugs, infections during pregnancy that are associated with autism.”

His comments highlight the need to understand autism through research into its different possible causes rather than focusing on vaccines. To which, Offit said that the vaccine-autism controversy has affected essential autism research.

When asked whether vaccine debates were diverting resources from research into autism causes and diagnosis, he pointed to the work of Alison Singer at the Autism Science Foundation and said there were several promising areas of investigation.

However, he criticised anti-vaccine groups for continuing to use autism as part of their arguments against vaccination. “I think that anti-vaccine groups have sadly taken the autism story hostage,” he said.

He argued that this had reduced the attention and resources that could go towards more promising areas of autism research. “So they hurt children with autism in the end,” he said.

On Revising Autism-Vaccine Debate

When asked what new evidence could make him reconsider his position on vaccines and autism, Offit said he would be open to changing his mind if a particular standard of scientific evidence were met.

“If there was an excellent retrospective study that controlled for things like healthcare seeking behavior, socioeconomic background, medical background, maternal health, et cetera, that was published in an excellent scientific journal and reproduced, then I'm willing to change my mind,” he said.

He added that a study would have to account for factors that could influence the results and be independently reproduced. “But until then, you're just hearing a lot of conspiracy theory and hand-waving,” he said.
