Taxi drivers have less risk of neurodegenerative diseases (Credit: Canva)
Becoming a taxi driver is no easy feat; it requires knowing practically every nook and corner of the city. Some neuroscientists in London saw an opportunity to study how the brain might change in response to the heavy demand for navigational and spatial memory. What they found is flabbergasting. They discovered that taxi drivers are less likely to develop Alzheimer's disease compared to people in other professions.
This study intrigued another group of scientists, who, in their study published in The BMJ, also examined drivers with fixed routes, such as bus drivers, ship captains, and aircraft pilots. "The results surprised us. We found that the two occupations with the lowest rate of Alzheimer’s death among all occupations studied were taxi drivers and ambulance drivers. Taken together, their risk of dying from Alzheimer’s disease was 56% lower than the general population at any given age." Taxi and ambulance drivers did not have lower rates of death from other forms of dementia, for which the hippocampus may be less involved.
However, bus drivers, aircraft pilots, and ship captains—the jobs with less spontaneous decision-making—had Alzheimer’s death rates typical of the rest of the population. This suggests that routine navigation along highly frequented routes might not impact the brain in the same way. Current research suggests there may be some cognitive activities, like games and simulations, that could help slow cognitive decline in the elderly, and research is ongoing on brain ageing.
Meanwhile, neurologists across the world have advised that brain games and puzzles can slow down brain ageing. research shows that brain-training games may help improve attention levels, memory, response time, logic skills, and other measures of cognitive function if played over a long period. And the good news is that these brain games are affordable and easily accessible to all. you just need a pen and paper for sudoku and the same goes on for crosswords. You can try these few games:

We all have habits we know are bad for us, yet we don’t stop doing them. Most smokers know that smoking is bad for their health, and even say they would like to quit, but something stops them. The National Institute of Health (NIH) explains how 70% smokers say they would like to quit, people who abuse drugs and alcohol also wish to give up their addiction but find it extremely difficult.
As such, there are many habits, people think do not harm them, but can take a toll on their body. In a recently posted video, Cardiologist Dmitry Yaranov, listed 5 habits that are slowly chipping away at your health.
In the video caption, Dr Yaranov explained that these habits, often picked up by mistake, can make your body weaker and more susceptible to illnesses.
Telling yourself, "I'll sleep when I'm dead," is a shortcut right to that outcome. Chronic lack of rest isn't just tiring; it’s physically damaging. Skimping on sleep constantly raises your blood pressure, makes you gain weight, and guarantees a serious burnout that you won't be able to recover from easily. Prioritize rest now.
From your office chair to the car and the couch, sitting for too many hours is silently wrecking your health. Being constantly still tightens your back, slows down your metabolism, hurts your digestion, and weakens your heart. Your body needs regular movement to survive, not just a ten-minute walk. Get up and move more often.
Saying "I'm fine" while carrying the weight of the world is a dangerous habit. Eventually, your body will stop listening to your mind. Stress you try to ignore explodes into physical problems, like unexplained chest tightness, constant gut issues, severe insomnia, and sudden panic attacks. Acknowledge your stress before it breaks you.
Skipping your morning meal, grabbing drive-thru lunch, and relying on sugar for quick energy creates chaos inside you. This erratic eating causes your blood sugar to swing wildly, stressing every major organ. Your body needs consistent, nutritious fuel, not a constant roller coaster of sugar and grease. Feed your body well, not fast.
You are always available, doing favors and taking on tasks for everyone else. But when was the last time you put your own needs first? Overcommitting drains your energy, time, and mental resources until there’s nothing left. This chronic neglect leads to resentment and exhaustion. Guard your boundaries and put yourself on the list.
Kicking any kind of habit can be difficult. The NIH explains that habits are just routines that we do without thinking. They are a normal, often helpful part of life, but they can also be things that harm your health.
While some habits are useful and do not require a lot of thinking, like brushing, showering, driving, other habits are based off-of pleasure or dopamine hit like smoking. Both types of habit use the same mechanics, but pleasure-based habits are much harder to break because of a chemical called dopamine.
The good news is that humans are not completely controlled by habit. We have other brain areas that can help us make better choices for our long-term health. There is no single solution; what works depends on the person. Dr. Volkow emphasizes that it's "not one size fits all." However, scientists recommend a few helpful techniques:
Figure out the exact time and place where your bad habit happens. Knowing your triggers is the first major step toward taking back control. Next, make a plan to avoid those spots. If the candy machine is your weakness, take a different route. Stay away from people who tempt you.
Before you face a tempting situation, close your eyes and picture yourself succeeding. Imagine choosing water over a sugary drink. Mentally rehearsing the healthy choice can prepare your brain. This practice boosts your chances of making the right decision when the real moment arrives.
Don't just stop the bad habit; actively replace that routine with a new, healthy activity. Fill the void with something constructive. Many people successfully replace strong urges, even addictions, with intense exercise like running. A new ritual helps fight the old habit's pull.

As COVID and viral infections cases rise in numbers, researchers are finding out how, following the bout of cases, the risk of heart diseases has also increased in people. To explore this connection, new research published today in the Journal of the American Heart Association reveals a strong link between both acute and chronic viral infections and an increased risk of serious cardiovascular events, such as heart attacks and strokes.
The lead author, Dr. Kosuke Kawai, noted that while we know viruses can cause cancer, their link to non-infectious diseases like heart disease hasn't been clear. This study confirms that acute (short-term) and chronic (long-term) viral infections are connected to both immediate and lasting risks for heart and brain events.
When your body fights off a virus, your immune system releases chemicals that cause inflammation (swelling) and make your blood more likely to clot. Both of these problems can linger even after the virus is gone.
This ongoing inflammation and tendency to clot can damage the heart and blood vessels, which is likely why the risk of a heart attack or stroke spikes so dramatically right after an illness.
The research details what happens to your heart risk right after you get a respiratory infection. The study combined data from many high-quality reports and found a major, temporary jump in risk:
In the month immediately following a confirmed flu infection, people were 4 times more likely to have a heart attack and 5 times more likely to have a stroke compared to when they weren't sick.
After a COVID infection, the risk was also high. People were 3 times more likely to have a heart attack and 3 times more likely to have a stroke in the first 14 weeks. Worryingly, this risk stayed higher than normal for an entire year.
This part of the study focused on people who have had certain chronic (long-lasting) viral infections, tracking their health for an average of over five years to see if their risk remained high:
People with HIV had a 60% higher risk of heart attack and a 45% higher risk of stroke.
This infection was linked to a 27% higher risk of heart attack and a 23% higher risk of stroke.
Even this common virus was associated with a 12% higher risk of heart attack and an 18% higher risk of stroke.
Even though these percentage increases are smaller than the immediate post-flu/COVID jump, they are still very important because the risk lasts for years. Shingles, for example, affects about one in three people in their lifetime, meaning that this seemingly small increase in risk will lead to a large number of extra heart problems across the general population over time.
The study suggests a powerful way to fight these risks is by getting vaccinated. The findings strongly support the idea that increasing the number of people who get flu, COVID, and shingles shots could lower the overall rate of heart attacks and strokes in the community. As an example, previous research has shown that getting a flu shot can be linked to a 34% lower risk of major heart problems.
The American Heart Association recommends that everyone, especially those with existing heart conditions or heart risk factors, talk to their doctor about getting the right vaccines. Vaccination is a simple step that offers crucial protection to people whose hearts are already vulnerable.
It’s important to remember that this study was based on looking at people's health records (observational studies), not on controlled experiments. The main focus was on single viruses. Researchers noted that we still need more studies to fully understand how some other viruses, like dengue and HPV, might be linked to heart disease.

Is India getting drunk? While rest of the world is cutting its alcohol consumption, India's shows some contradicting results. As per a London-based market analytics firm Euromonitor International, the country is projected to consume an additional 357 million litres between 2024 and 2029. This is the biggest increase anywhere in the world.
the report titled World Market for Alcoholic Drinks 2025 notes that the there is a stagnating overall in alcohol consumption, and the only high points are countries like India, Brazil, Mexico, and South Africa.
The reason is Zebra Stripping. What exactly is that? Zebra Stripping is the act of switching between alcoholic and non-alcoholic drinks in the same social setting. The Print reported that people in India are moderating their alcohol consumption, rather than completely dismissing it. People, however, are avoiding binge drinking, and switching to zebra stripping.
Health is the main driving factor of this change. There is a generational divide among the Gen Z adults of legal drinking age. As 36% of them have never consumed alcohol. This is the case globally too. For instance, in the US, the National Institute of Drug Abuse shows that lifetime drinking, past month drinking, and past year drinking among young people have declined from year 2000. This means that the decline is most severely seen among the Gen Z, those who are born between 1997 to 2012.
Despite this drop in Gen Z drinkers, the report, aforementioned, shows the number of alcohol consumers will only increase.
The National Institute on Alcohol Abuse and Alcoholism notes that alcohol could lead to organ damage and immune dysregulation. Alcohol could cause cardiac arrhythmias, cardiomyopathy, ischemic heart disease, hypertension, ischemic stroke or hemorrhagic stroke, acute respiratory disease, distress syndrome, pneumonia, oesophageal cancer, and oral cavity cancer.
Other impact that alcohol could cause on one's body are:
It can also increase the risk of liver, colon, breast, oral cavity and rectum cancer.
The Centers for Disease Control and Prevention (CDC), USA, notes that around 178,000 deaths have happened in the US, annually, just by excessive alcohol use. CDC notes that while drinking levels at any point is not safe, moderate alcohol use is only up to two drinks or less in a day for men, and one drink or less in a day for women.
Apart from the diseases and chronic conditions, CDC notes that alcohol use could also lead to injuries through motor vehicle crashes, falls, drownings, and burns. It could also lead to violence, overdose, alcohol poisoning, sexual transmitted infections, miscarriage, stillbirth, or fetal alcohol spectrum disorder (FASD).
