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.

Vaccinated for human papillomavirus (HPV)? Now, take that Pap smear test. This is the most common advice women hear to prevent the risk of cervical cancer that annually causes around 6,60,000 new cases and around 350,000 deaths worldwide.

However, it's easier said than done for most of the fairer sex.

A Pap smear is typically a gynecological examination where a speculum is inserted to collect cells from the cervix.

Although the procedure is brief and generally safe, the discomfort discourages many from getting screened. Fear of pain, anxiety of the results, form the common psychological barriers worldwide, and is followed by shame, cultural attitudes, and concerns with male clinicians.

A study in Iran, published in the BMJ Open journal in January 2024, showed that psychological stress, cultural issues, and fear, along with limited information and health services, were the biggest hindrances to getting Pap tests.

Another research published in the BMC Women's Health in December 2022, focusing on Africa, Asia, and South America, reported that many women avoided or delayed Pap smears because they are afraid the procedure will hurt. Many also reported being embarrassed about the pelvic exam or fear of having a stranger see their private areas. Some also worried that the test could damage the uterus.

A Pap Smear test, however, is proven to be safe and is recommended for every woman above the age of 21 years.

“A Pap smear is a rapid, safe, and painless screening procedure that detects irregular cellular changes well before they become malignant. The ability to treat at this pre-cancerous stage of disease provides an excellent outcome,” Dr. Tirathram Kaushik, Senior Consultant GI, HPB, Gastrointestinal & Thoracic Oncology and Robotic Surgery, HCG Cancer Centre, Borivali, told HealthandMe.

A 2025 study, published in the Journal of Contemporary Clinical Practice, showed that pap smears are excellent at ruling out precancerous risks. It also remains a valuable screening tool where molecular testing is limited.

There are many myths about Pap smears that make people anxious or avoid screening. Let’s clear up the most common ones:

Pap Smears Are Painful

The Pap smear procedure, which takes only a few minutes, is often described as uncomfortable. While some feel like a quick pinch, others experience slight discomfort or spotting. Severe pain is not considered normal.

“From an oncology perspective, this myth results in a delay in diagnosis. Cervical cancer often occurs silently in its early stages, without any noticeable symptoms,” Kaushik said.

I Am Healthy, So I don’t need A Pap Smear

While individuals may feel completely well, they still have abnormal cells developing silently. As a result, regular Pap smear screening is important because it detects these changes early -- before they turn into cervical cancer.

“The HPV infection and subsequent changes that lead to cervical cancer happen slowly over many years. HPV infection is also very common, and one in two women is likely to get infected. Regular screening by a Pap smear will help to catch infection early before it can convert into cancer,” Dr. Deepak Jha, Chief - Breast Surgery & Sr. Consultant Surgical Oncology, Artemis Hospitals, told HealthandMe.

I Have Only One Partner, So I don’t need Screening

“HPV doesn’t need penetrative sex for infection. It can be transferred if there is any contact of bodily fluid. It’s always safe to test and be assured rather than repent later,” Dr. Jha said.

Testing Means Cervical Cancer

“Even if HPV is detected, it usually indicates a pre-cancerous stage that is highly treatable,” Dr. Parminder Kaur, Consultant Gynecologic Oncologist at CK Birla Hospital, Delhi, told HealthandMe.

Moreover, a Pap smear only screens for cervical cancer; it can’t detect other gynecological cancers such as cervical, ovarian, uterine (endometrial), vaginal, and vulvar cancers. So, screening and appropriate tests for those will be required, irrespective of the Pap smear.

I Am old, So I don’t need A Pap Smear

I Got Vaccinated, So I Do Not Need A Pap Smear

Irrespective of vaccinated status, a woman should go for regular screening between the ages of 25 and 79. Also, if a woman already had HPV exposure before being vaccinated, she would not benefit, the experts said.

“Screening is not just a routine procedure - it is a preventive measure. In the treatment of cancer, early detection alters the disease course, whereas waiting for symptoms to develop means the disease is likely to be already advanced,” Dr. Kaushik said.

Dr Kaur called for more awareness and stated that open discussion are key to help more women take the important screening test.

When To Get Screened

The United States Preventive Services Task Force (USPSTF) and the American Cancer Society (ACS) recommend getting your first Pap test at age 21, followed by Pap testing every 3 years. Even if you are sexually active, you do not need a Pap test before age 21.

• Individuals must start getting Pap tests at age 21. If the result is normal, repeat the test after three years.
• For individuals aged between 30 and 65 years old, doctors are likely to recommend an HPV test along with a Pap test. If both are normal, repeat after five years.

In women older than 65, you don't need to be screened anymore if:

• You have had at least three Pap tests or two HPV tests in the past 10 years, and the test results were normal or negative, and
• You have not had a cervical precancer in the past, or
• You have had your cervix removed as part of a total hysterectomy for non-cancerous conditions, like fibroids.

Are you still experiencing brain fog, fatigue, and mood changes even after years of a mild COVID-19 infection? A new study showed that the SARS-CoV-2 virus, behind the COVID infection, can cause persistent brain inflammation and lung injury, according to a study.

Researchers from Tulane University, in Louisiana, US found that the brain inflammation lasts long even after the virus was no longer detectable.

Their study, published in Frontiers in Immunology, can answer why long COVID often includes neurological symptoms such as brain fog, fatigue, and mood changes.

"Long-term effects on the brain were unique to SARS-CoV-2. That distinction is critical to understanding long COVID," said lead author Dr. Xuebin Qin, professor of microbiology and immunology at the Tulane National Biomedical Research Center. Qin also mentioned "lasting lung injury" among COVID patients.

In a mouse model, the team found that immune cells in the lungs failed to fully stand down and also spiked the buildup of collagen -- a protein associated with scarring.

The changes stiffened lung tissue, making breathing feel more labored -- a possible answer to breathlessness faced by COVID survivors.

Further, the researchers also noted no repair to the injury, suggesting the virus may interfere with the lung's natural healing process.

On the other hand, in the brain, the mice with COVID showed signs of persistent brain inflammation weeks later. The team also reported tiny areas of bleeding.

Conducting a gene expression analysis, the team found ongoing inflammatory signaling and disruption of pathways involved in serotonin and dopamine regulation -- brain functions linked to mood, cognition, and energy levels.

What Is Long COVID?

Long COVID is a collection of symptoms that last three months or longer after your first COVID symptoms. They include fatigue, brain fog, headaches, breathlessness, altered sense of smell or taste, headaches, and more.

While many of the Long conditions remain to be fully recognized, some people have more than one symptom.

mRNA Vaccine Against COVID

As per recent data from the World Health Organization, more than 43,000 new cases have been reported from 61 countries, between January and February.

Vaccination that prevents SARS-CoV-2 infection is the most effective way to prevent long COVID.

Recently, the European Medicines Agency (EMA) recommended a marketing authorisation in the European Union (EU) for mCombriax -- a messenger RNA vaccine for protecting people aged 50 years and older against COVID-19 and seasonal influenza (flu).

Co-infection with the influenza virus and SARS-CoV-2 can result in more severe disease than would occur with either SARS-CoV-2 or influenza virus infection alone.

mCombriax works like other vaccines by preparing the body to defend itself against infection. It contains messenger RNA with instructions for making proteins found on SARS-CoV-2 and the following seasonal influenza viruses: influenza type A-H1N1, influenza type A-H3N2, and influenza type B of the Victoria lineage.

Vitamin B12 might sound like just another nutrient on a health label but it plays a major role in how your body works. The vitamin is crucial in helping the body produce red blood cells, supports your nervous system and essential for making DNA, which is the genetic material inside all your cells.

Symptoms of a Vitamin B12 deficiency often appear slowly. You may not notice them at first, or may blame them on stress, lack of sleep or a busy schedule. However, if this deficiency continues for too long, it could lead to serious health problems.

Here are three key signs to look out for:

1. Ongoing Fatigue and Weakness

Vitamin B12 is extremely crucial for making red blood cells who are responsible for carrying oxygen from your lungs to the rest of your body. Oxygen is what your cells need to produce energy.

Without adequate levels of B12, the body cannot produce enough healthy red blood cells, leading to a condition called anemia.

This can make you feel constantly exhausted, even after getting enough sleep. You may also feel weak, short of breath or find that everyday tasks feel harder to do than they generally are.

If the fatigue feels persistent and does not improve with rest, it is important to seek a consultation with a doctor.

2. Tingling or Numbness in the Hands and Feet

Vitamin B12 is also essential for maintaining the myelin sheath, a protective covering around your nerves. You can think of it like the protective plastic that we see around electrical wires. It helps nerve signals travel quickly and correctly between your brain and the rest of your body.

When B12 levels are too low, this protective layer can become damaged and subsequently lead to nerve signals slowing down or misfiring. This may lead you to feel pins and needles, tingling or numbness in your hands and feet. Some people also experience burning sensations or difficulty with balance.

At first, it may seem minor, such as your foot ‘falling asleep’. But if these sensations happen often or without a clear reason, they should not be ignored. Long-term B12 deficiency can cause permanent nerve damage, which is why early medical consultations are important.

3. Brain Fog, Memory Problems or Mood Changes

Your brain also depends on vitamin B12. It helps your body produce neurotransmitters, which are chemicals that allow brain cells to communicate with each other. These chemicals influence memory, focus and mood.

When B12 levels are low, communication between brain cells may not work as efficiently. You may notice difficulty concentrating, forgetfulness or a feeling of mental fog. Some people feel more irritable, anxious or unusually low in mood.

As these symptoms are common during stressful times, they are often dismissed. However, if you feel mentally different from your usual self for a long period, it is important to investigate the cause.

Why Does B12 Deficiency Happen?

Vitamin B12 is mainly found in animal-based foods such as meat, fish, eggs and dairy products. People who follow vegetarian or vegan diets may need fortified foods or supplements to get enough.

Absorption is also a key factor. Vitamin B12 needs a special protein in the stomach called intrinsic factor to be absorbed properly. Certain medical conditions, medications, or aging can reduce absorption. This means that even if someone eats enough B12, their body may not absorb it efficiently.

When to See a Doctor

If you experience ongoing fatigue, tingling sensations or noticeable changes in memory or mood, consult a healthcare professional. A simple blood test can measure your B12 levels.

The good news is that Vitamin B12 deficiency is usually treatable. Treatment may include dietary changes, oral supplements or, in more severe cases, injections. When identified early, most people recover well.

The Bottom Line

Vitamin B12 supports your blood, nerves and brain. A deficiency can quietly affect your energy, sensation and thinking over time.

Pay attention to persistent changes in your body. If something feels consistently wrong, it is important to seek medical advice. Early detection can prevent long-term complications and help restore your health.
