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.

Smell is a sense that helps us navigate, feel, and in fact remember things. Thanks or not, but Covid-19 also helped us know its importance, when many people lost the sense of their smell, as one of the major COVID-19 symptom. But, that is not just it, in a podcast posted on Instagram Dr Sanjay Bhojraj, board-certified interventional cardiologist talked to Dr Michael Leon, PhD Professor Emeritus of Neurobiology and Behavior at the Charlie Dunlop School of Biological Sciences on surprising link between smell and overall well-being.

Can Smell Predict How Long Will You Live?

“By the time you reach middle age, your sense of smell can actually predict all-cause mortality,” says Dr Leon. “That means whether you live or die, for any reason, can be accurately reflected in your ability to detect odors.”

The expert says that out olfactory system bears a direct impact to the brain's memory and emotional centers. “It has a great deal of impact when you lose it. And also when you amplify it. When you smell a pleasant odor, it activates the cerebellum and increases sniffing. For example, when you smell a rose, you naturally take a deep sniff.”

How Does Smell Impact Your Brain?

When you encounter a bad or disgusting odor, your body reflexively stops respiration. You instinctively avoid breathing it in,” Dr Leon says.

The expert said it is these subtle responses that influence one's memories, emotions, and overall brain function. “The olfactory system is just much more powerful than most people realize,” he says.

Can Body Odor Also Reveal Things About Your Health?

This link between smell and health became famous when Joy Milne, a retired Scottish nurse, claimed she could detect Parkinson’s disease by scent alone. Years before her husband’s diagnosis, she noticed a distinct musky odor on him. When she later met others with Parkinson’s, they all carried the same smell. Curious scientists put her to the test — and she correctly identified patients just by sniffing their shirts, even predicting one man’s diagnosis a year before doctors confirmed it.

Her unique ability led researchers like Professor Perdita Barran at the University of Manchester to discover that people with Parkinson’s excrete specific lipid-like molecules through their skin. These include hippuric acid and octadecanal, which may form the disease’s distinct odor. Barran’s team is now developing a simple skin-swab test that could help doctors detect Parkinson’s much earlier.

Different diseases create different odors. For example, a fruity or “rotten apple” smell can indicate uncontrolled diabetes, caused by a build-up of ketones. A fishy or ammonia-like scent might suggest kidney problems, while a musty smell could point to liver disease. Even infections leave olfactory traces — cholera, tuberculosis, and C. difficile each produce distinct, unpleasant aromas.

Did you also wake up with a mild cold? A sneeze, blocked nose and a sore throat. It is worse because you had just shaken off the miserable cold and your energy was finally coming back and then now again you are sneezing. So, now the question is, could you really get the same cold twice, or is it just your bad luck?

As per the National Health Service, UK (NHS), adults could get an average of 2 to 4 colds a year. The NHS, UK notes that the viruses behind them behave in a complicated way. This is because some mutate quickly, and some stay in your system. This is why your body's ability to fight them off can differ depending on how well does your immune respond.

Catching The Same Cold, Twice

Conventionally, it is believed that once you have a virus, your body recognizes it and does not let you catch the same virus again. However, this is not the case, always.

Professor Brain Ferguson, who is the professor of viral immunity at the University of Cambridge told Yahoo UK, that it is possible to catch cold twice. This is due to the levels of antibodies that we have in our system.

Ferguson says, "It depends on the quality of the antibodies that your body generates when you get infected the first time. Sometimes your body might make really good ones, and that will stop you being reinfected with the same virus later. But another person might not, and they can catch the same virus, exactly the same one, again later."

The expert further added, "It is also down to the actual molecules, and the constituents of the virus, like proteins and things you make antibodies against. The longer they exist in your body, the better the antibody response tends to be."

This means that the cold can stay in your system, and the longer it stays the better your immune system will be prepared to build up a stronger defense.

Reinfection Time: How Long Does It Take?

If you had two colds very close together, you may not have had enough time to build immune response the first time. Ferguson says, "Reinfection can be very fast."

"It can be as soon as a couple of weeks if the antibody response is very weak... You might pick up a virus and get a few minor symptoms, but fight it off really quickly. In that case, you get much weaker antibodies that fight the virus, which means the same virus appears in your system again very quickly."

This means your body only has a "fleeting encounter" with the virus and thus it won't remember it well enough to protect you the next time. However, a more severe cold may trigger a stronger immune response, which can work as a longer-lasting protection.

Why Some People Catch More Often?

This has something to do with genetics. This is because of their immune system, how good it works against different infections. As Ferguson says, "Some people are just naturally better or worse at fighting off viruses or bacteria due to their genetic makeup."

While it is believed that multivitamins and supplements can help "boost" immunity, Ferguson says that the evidence is mixed.

There’s not a great evidence base for [vitamins] for repeat infections," he says. However, Ferguson adds there is evidence that people who spend more time outside and get more vitamin D tend to have a slightly better-functioning immune system.

"I wouldn't use the word hide," said Dr Sue Goldie to NPR, she is a professor at the Harvard TH Chan School of Public Health, who has finally told the world after four years about her Parkinson's.

She learned about her diagnosis in 2021. She told NPR, "I think I was really trying to give myself room and time to fall apart, to panic, to think about what it meant for me.” For Goldie, silence wasn’t secrecy, it was self-preservation.

She revealed she needed space to understand to first accept that it is happening with her, and secondly to understand how to live with a condition that would alter her movements, her voice, and even her sensing. So she calls the 4-year-gap of not telling anyone as a "process of figuring out how I could be OK."

Parkinson's Disease: How Does It Start?

We often read about Parkinson's disease, what is it, and what it does to someone. However, what we do not talk a lot about is how it starts. We don't talk about the subtle signals one's body sends.

Goldie says it started with a tremor. It was so slight, that it was almost invisible. Then, a running coach mentioned her off cadence. The New York Times (NYT) reports that a trainer noticed her left arm did not lift properly in the pool. Eventually, afterwards, her fingers began twitching. Goldie, then was 50.

She was also at the height of her academic career and was newly obsessed with triathlons. She was in fact, training for Ironman races, reported NYT.

When tests confirmed Parkinson’s, a degenerative neurological disease that affects movement and coordination, her first reaction was disbelief. Then fear. Would her students notice? Would colleagues see her differently?

The diagnosis left her confronting an identity crisis. At what point, she wondered, does a disease become who you are?

Sue With Parkinson's, Who Lived Two Lives

Goldie began to divide her world. At Harvard, she was the confident professor and global health leader, still producing intricate teaching materials and mentoring students. In triathlons, she was freer, surrounded by people who saw her as an athlete, not a patient.

But the effort to maintain that balance came at a cost. As reported by NYT, early mornings were the hardest: walking unsteadily to the bathroom before medication took effect, hiding tremors from colleagues, managing the dopamine pills that controlled her symptoms. “You have no idea how hard it is to trick you into thinking I’m OK,” she later said.

Eventually, she could no longer keep it private. “Starting today, I am Sue with Parkinson’s,” she decided. Most of the people in her professional life would learn about it through her story.

The Camera For Healing

When Goldie's hand tremors made writing impossible, she began to record thousands of video diaries. They were often short, unfiltered glimpses of her daily struggle, which were filmed in her office, car, or home. Sometimes, calm, sometimes in tears.

Her videos began with a "Hello Sue", talking to her future self. In one video as posted by the NYT from 2023, she confessed, “I’m trying hard to do all this stuff that will help, but I’m not feeling OK... I just need to not be alone with it.”

Goldie refused to stop training. Her research had shown that exercise helps manage Parkinson’s symptoms. So, she doubled down, calling herself “an N of 1” — a one-person experiment. She adapted creatively: pink tape on her hands to guide her swim strokes, modified gear on her bike so she wouldn’t lose balance.

In 2022, she completed the Lake Placid Ironman, a 140.6-mile challenge. She crossed the finish line after collapsing, crying, and reapplying lipstick. Her small team called her S.F.G., with the middle initial standing for an unprintable word that captured her spirit.

As her symptoms progressed, Goldie’s fears shifted from physical decline to the erosion of identity. Parkinson’s, she realized, isn’t just about tremors; it’s about dignity, perception, and the quiet grief of being misunderstood.

She worried about whispers at Harvard, about whether others would still see her as capable. When she finally told university leaders, she felt both vulnerable and relieved.

Still, her mission remained unchanged. “I can’t change this,” she told The New York Times in 2024. “So what happens when I get worse?”

She continued teaching, designing, and mentoring. Her hands might tremble, but her mind stayed sharp. “I want to get things done while I’m still the best me,” she said.
