The brain is the most complex organ in the human body. Even after all the scientific advancements, neuroscientists haven't discovered the exact percentage of the brain that we use. Some people believe that we may never be able to fully fathom the brain's capacity, but evidence suggests neuroplasticity is the key.

Neuroplasticity is described as the brain's ability to restructure or rewire itself when adapting to change. It can continue to develop throughout life in response to stimulation, environmental changes, and individual experiences.

Here are six scientifically supported methods to stimulate and rewire your brain:

1. Play Video Games

Video games often spark debates about their ill effects on health, especially mental health. However, research has shown that they have significant cognitive benefits. Online gaming can improve motor coordination, spatial navigation, memory, and decision-making. In addition, it can also foster qualities like leadership and teamwork.

Different genres of games offer unique benefits. For example, 3D adventure games enhance memory and problem-solving, puzzle games boost brain connectivity, and rhythm-based games improve visuospatial skills. Notably, these benefits begin to emerge after about 16 hours of gameplay, spread across regular sessions.

By teaching you to recover from failure or explore creative solutions, video games may also enhance real-world skills such as adaptability and critical thinking.

2. Learn a New Language

Mastering a new language strengthens both grey and white matter in the brain. Research has shown that when you learn a new language, grey matter—responsible for language, memory, and motor skills—volume increases, while white matter enhances connectivity between brain regions.

These changes contribute to improved problem-solving, better multitasking, and higher reading comprehension. Additionally, bilingualism can reduce cognitive decline and dementia risks as you age. To master a new language, you can explore in-person or online classes.

3. Make Music

Listening to and playing music stimulates neuroplasticity by engaging multiple brain pathways. Studies show that music can improve coordination, memory, and mood while slowing cognitive decline. Learning an instrument—even as an adult—can bolster brain health. Affordable options like the ukulele or keyboard, paired with free online tutorials, make it easier to start.

4. Travel

Exploring new places boosts cognitive flexibility, creativity, and communication skills. Experiencing different cultures broadens your perspective. It also gives you time to introspect and in the process, provide new personal and professional goals.

Even local adventures, like walking through unfamiliar neighbourhoods or trying virtual travel experiences, can stimulate your brain. These small shifts in routine encourage adaptability and mental growth.

5. Exercise Regularly

Physical activity not only benefits your body but also strengthens your brain. Motor coordination and neural connectivity are two important parts that are boosted by regular exercise. It also reduces risks of anxiety, depression and neurodegenerative diseases.

Centres For Disease Control and Prevention (CDC) recommend at least 150 minutes of moderate exercise weekly. Activities like group workouts also provide social interactions that contribute to emotional well-being.

6. Create Art

Art-making—whether sketching, painting, or doodling—fosters creativity and enhances cognitive abilities. it taps into the brain's default mode network, which facilitates mental relaxation, creative problem-solving, and habit interruption.

Wildfire Smoke May Rewire Your Immune System, Scientists Warn: Here’s How It Impacts Your Health

Updated Jul 2, 2025 | 12:00 AM IST

SummaryNew research reveals wildfire smoke can alter the immune system at a genetic level, increasing inflammation, allergy risks, and vulnerability to illness—even in healthy individuals.

As wildfires become an all-too-familiar headline across the globe, their visible devastation—scorched forests, lost homes, and displaced communities—often overshadows a more insidious threat: the impact of wildfire smoke on human health. While the immediate dangers of flames and evacuations are clear, a new study published in Nature Medicine reveals that wildfire smoke does far more than irritate eyes and throats. It can fundamentally alter the immune system, potentially making people more susceptible to illness long after the smoke has cleared.

The study, led by researchers from the Harvard T.H. Chan School of Public Health, found that people exposed to wildfire smoke exhibit changes in gene expression and immune function, even if they’re otherwise healthy. This suggests that the health consequences of wildfires may extend far beyond the immediate coughing, wheezing, and watery eyes that so many experience during fire season.

How Smoke Alters Immunity?

The research, led by Dr. Kari Nadeau of the Harvard T.H. Chan School of Public Health, provides the most detailed look yet at how wildfire smoke affects the body on a cellular level. By analyzing blood samples from 31 firefighters and civilians exposed to wildfire smoke and comparing them to 29 unexposed individuals, the study uncovered a complex web of immune changes.

People exposed to wildfire smoke showed a marked increase in memory immune cells—cells that typically provide long-term immunity. At first glance, this might seem beneficial, but the study also found elevated biomarkers of inflammation and immune activity, as well as changes in dozens of genes linked to allergies and asthma. In short, the immune system was not just activated—it was thrown into overdrive, potentially increasing vulnerability to illness.

Dr. Mary Johnson, the study’s lead researcher, explains, “Our findings demonstrate that the immune system is extremely sensitive to environmental exposures like fire smoke, even in healthy individuals. Knowing exactly how may help us detect immune dysfunction from smoke exposure earlier and could pave the way for new therapeutics to mitigate, or prevent altogether, the health effects of smoke exposure and environmental contaminants.”

What’s in Wildfire Smoke?

Wildfire smoke is a toxic brew. It contains:

  • Fine particulate matter (PM2.5)
  • Toxic gases
  • Heavy metals
  • “Forever chemicals” like PFAS
  • Cancer-causing compounds

The ultra-fine PM2.5 particles are particularly dangerous. At less than 2.5 micrometers in diameter, they are 28 times smaller than the width of a human hair and can be inhaled deep into the lungs, enter the bloodstream, and affect organs throughout the body.

“These findings suggest that even short-term exposure to wildfire smoke can act as a biological stressor with long-lasting effects,” said Dr. Mary Johnson, lead researcher and environmental health scientist at Harvard. “That’s especially concerning as wildfire seasons grow longer and smoke plumes travel farther.”

What are the Genetic Impacts of Wildfires?

One of the most striking findings of the study was the alteration of 133 genes related to allergies and asthma in those exposed to wildfire smoke. This genetic shift may help explain why people living in wildfire-prone areas often report more respiratory problems, even months after the fires have ended.

The study also found that smoke-exposed individuals had more immune cells affected by toxic metals, further increasing inflammation and the risk of immune dysfunction. These changes may make people more susceptible to infections, worsen existing respiratory conditions, and potentially contribute to the development of new allergies or asthma.

The United States, particularly western states like California, has witnessed a dramatic increase in wildfire frequency and severity. In 2023 alone, California experienced over 7,000 wildfires, with the California Department of Forestry and Fire Protection responding to nearly 590,000 related emergencies. The devastating January 2025 fire in Los Angeles County, which claimed 30 lives and scorched 40,000 acres, underscored the deadly toll of these disasters.

Climate change is a major driver, creating hotter, drier conditions that fuel longer and more intense fire seasons. As wildfires become more common, understanding and mitigating the health risks of smoke exposure is more urgent than ever.

What are the Immediate and Long-Term Health Effects?

Wildfire smoke can trigger a range of symptoms, from burning eyes and runny noses to persistent coughs and breathing difficulties. For people with pre-existing conditions like asthma, COPD, or eczema, exposure can lead to dangerous flare-ups.

But the risks extend beyond the lungs. Fine particulate matter (PM2.5) can enter the bloodstream, causing inflammation throughout the body. Studies have linked wildfire smoke to increased emergency room visits for heart attacks and coronary heart disease within 24 hours of exposure. There is also emerging evidence that PM2.5 can impair cognitive functions such as memory and attention, likely by inducing inflammation in the brain.

How to Protect Yourself and Your Family?

Experts emphasize the need for proactive measures as wildfire season peaks:

  • Stay indoors when smoke levels are high. Keep windows closed and seal gaps in doors.
  • Use HEPA-grade air purifiers to reduce indoor particle pollution.
  • Wear a certified N95 mask when outdoors, especially if you’re in a smoke-affected region.
  • Monitor air quality via apps or government alerts, such as AirNow.gov.
  • Avoid outdoor exercise when AQI levels are poor; opt for indoor alternatives instead.
  • Keep emergency medications handy, especially for people with asthma or heart conditions.

If evacuation orders are issued, follow them promptly—not just for safety from flames, but from the health threats the smoke carries.

As wildfires continue to reshape landscapes and communities, their invisible legacy—on our immune systems and overall health—demands urgent attention. The message from scientists is clear: wildfire smoke is not just an environmental nuisance, but a profound health hazard that can affect anyone, anywhere the wind blows. Proactive measures, informed guidelines, and continued research are essential to protect public health in an increasingly fiery world.

24-Year-Old Suffered A Heart Attack Due To Vaping, Now He Has Permanent Lung Damage - 'I Have The Lungs Of A 70-Year-Old Now'

Updated Jul 1, 2025 | 07:00 PM IST

SummaryVaping may seem cool to young kids and teenager, but it can have a lasting impact on their health. This 24-year-old took to social media with his story to warn any teens or young adults who may vape.

Recent years have seen a rapid rise in kids vaping all over the world. A popular habit among young teens as well as young adults, vaping is the act of inhaling aerosol from electronic cigarettes or vape. But this popular habit has cost the health and well-being of this 24-year-old, who took to social media to warn people about this habit, as reported by the People.

“I Have Been Vaping Since The Age Of 12”

A young man is taking to social media with a serious warning for anyone who uses e-cigarettes. He claims that vaping caused him to suffer a heart attack at just 24 years old and has led to lasting lung damage. Through a series of TikTok videos, Jacob Temple from Kentucky is urging people to quit vaping right away.

Temple, who started vaping at age 12, now says his lungs are like those of a 70-year-old man. He explained that he has permanent scarring on part of his lungs, meaning he can never fully inflate or deflate them again. "It feels like I’m breathing through a straw constantly, always, just never getting enough air and there’s nothing that can be done," he shared. This damage means he'll forever feel like he's not getting enough oxygen.

Lung Damage As Well As Suffering Heart Health

Temple also revealed that his vaping habit directly led to a "minor" heart attack, specifically an anterior myocardial infarction. He described the terrifying experience, saying, "My whole body was fighting to stay alive at a certain point." While the physical damage to his lungs can't be fixed, he hopes his story will motivate others to stop vaping before it's too late for them.

Temple admits he still has "good days and bad days." On some days, he can be active with the help of his rescue inhaler. However, on other days, he can barely function and struggles to sleep. He reflected on his past habit, saying, "It was fun while it lasted, but now I am paying for it dearly." His struggle highlights the long-term, painful consequences of what might seem like a harmless habit.

Research Warns Against Vaping

In a 2021 BMJ Case Reports study, researchers explored the link between vaping spontaneous pneumothorax, which is when air leaks into the space between your lung and chest wall, causing the lung to collapse. They also presented a case study of a A 34-year-old man, who was a healthy weight, came to the emergency room struggling to breathe and experiencing back pain for a full day.

An X-ray of his chest showed a large collapsed lung on his right side. He had quit regular cigarettes three years prior and switched entirely to vaping. A more detailed CT scan revealed bullae (air-filled sacs) in his lungs, and he had to undergo surgery to remove part of his lung. Lab tests on the removed tissue showed mild inflammation.

There are many other studies like the same, prompting researchers and healthcare professionals to issue warnings.

Temple’s case is not an isolated incident; there are many who have suffered the same fate.

How To Quit Vaping?

According to Heart Organization, quitting smoking or vaping for good can seem tough, but it's totally possible. Just take it one step at a time. Here are five easy steps to help you on your journey to a healthier life.

Pick Your "Quit Day" and Make a Promise

Choose a day within the next week when you'll completely stop. This is your "Quit Day"! Promise yourself and tell supportive friends you're quitting. Slowly cut down before this day.

Choose How You'll Quit

You have options: go "cold turkey" and stop all at once, or cut down slowly each day. For example, reduce cigarettes from 20 to 10, then 5. Or take fewer puffs from each one.

Talk to Your Doctor About Help

Speak with your doctor. They can tell you if medicines or other support tools, like patches or gum, would make quitting easier for you. Get their personalized advice to help you succeed.

Plan for Your Quit Day and Beyond

Get ready for your Quit Day! Have healthy snacks ready, like fruits or gum. Plan fun activities to keep busy when you feel like smoking. Try a walk, movie, or new hobby to keep your hands busy.

Are People Too Busy To Take Care Of Their Own Health? Study Finds Lack Of Check-ups Increase Chances Of This Eye Condition

Updated Jul 1, 2025 | 03:00 PM IST

SummaryTaking care of our own health is an important aspect of living, but statistics find that most of us fail to even get even basic checkups done.
Study Finds Lack Of Check-ups Increase Chances Of This Eye Condition

“Health is Wealth” is something we all teach our kids so that they learn to put themselves first, however many times they fail to learn it as we ourselves do not follow it.

While we are constantly urged to take care of our health above anything else, it is a message not many of us take seriously. Many people in the UK are putting their health on the back burner, claiming they're simply too busy.

A recent study reveals that one in five Brits are neglecting their own well-being, often skipping important appointments like eye exams, dental visits, and doctor's check-ups. In fact, three-quarters of people have either missed or postponed a health appointment because their schedules were too packed.

Why Are We So Busy?

The main culprits for these missed appointments seem to be work demands and childcare responsibilities. On top of that, the sheer stress of arranging the appointments themselves is another big reason adults avoid necessary blood tests or eye exams. This research, commissioned by Specsavers for Glaucoma Awareness Week, aims to shed light on glaucoma, often called the "silent thief of sight."

What is Glaucoma?

Glaucoma refers to a group of eye diseases that can lead to vision loss and even blindness. It does this by harming your optic nerve, which is like a cable at the back of your eye that sends images to your brain.

The tricky part about glaucoma is that its symptoms often begin so slowly you might not even notice them. This is why it's often called the "silent thief of sight." The only way to truly find out if you have it is by getting a thorough eye exam where your pupils are dilated.

While there's no cure for glaucoma, catching it early and starting treatment can often stop the damage and help protect your vision from getting worse.

Don't Wait for Symptoms

A spokesperson highlighted that it's easy to push check-ups aside when you feel fine and life is hectic. However, conditions like glaucoma can develop slowly without any noticeable symptoms. By the time you notice an issue, "irreversible damage" might have already occurred. That's why it's crucial not to wait for symptoms to appear; regular check-ups can help protect your long-term health.

Initially, glaucoma usually has no noticeable symptoms. This is a big reason why about half of the people who have it don't even know it.

Over time, you might slowly start to lose your vision. This often begins with your side (peripheral) vision, especially the part closest to your nose. Because this happens so gradually, many people don't realize their vision is changing at first. As the disease worsens without treatment, you may begin to notice significant blind spots and, eventually, it can lead to complete blindness.

Simple Tasks Often Overlooked

The study also found that busy adults often neglect other simple health tasks due to lack of time. These include getting a full night's sleep or drinking enough water. A significant number of people (one-fifth) admitted they've been so focused on work that they haven't taken proper screen breaks or even moved from their seats for long periods.

Among those who don't prioritize their own health, 28% put their children's needs first, while 19% prioritize housework. Sadly, over a third confessed that only a health scare or a clear symptom would finally push them to book a delayed check-up. Many understand the need for appointments but find them easy to forget.

Making Health a Priority

Many Brits believe that easier booking systems (four in ten) or simply more time in their day (a third) would help them focus more on their health. Specsavers emphasized that even though schedules are busy, ignoring eye care isn't an option. A quick eye check every couple of years can protect you from serious long-term problems. Your vision is incredibly valuable and deserves your attention.
