We have all seen movies where right before the hero starts fighting, he cracks his knuckles and makes it look like the coolest thing in the world! But then our parents told us that you should not crack your knuckles because that weakens your grip and hand strength. But is that true? While many people do say that they experience a small loss in strength immediately after they crack their knuckles, but are their long-term effects to it? And what is the sound actually coming from?

The reason why people crack their fingers is because the evident and sharp crack noise causes a sense of relief. Many people also do it when they have done an activity that required them to work with their hands a lot like typing or sewing, giving themselves a sense of satisfaction, similar to stretching after doing hard work. That "crack" sound can make some people cringe, while others find it strangely satisfying. Cracking your knuckles is a pretty common habit, but there are a lot of misunderstandings about it. Some people do it without even thinking, others can't stand the noise, and some can't crack their knuckles at all. You might have been told as a kid that it causes arthritis or makes your fingers swell up. But those are just old wives' tales. There's a real science behind this habit, and it's more interesting than you may think.

Why Do Knuckles Make That Popping Sound?

The "crack" isn't actually bones breaking or anything bad happening to your joints. It's a normal thing called "crepitus." This just means harmless popping, snapping, or grinding sounds that come from your joints. The main reason you hear this sound is because of gas bubbles in the fluid that cushions your joints. This fluid is called synovial fluid. When you move or stretch, these tiny bubbles form and then pop, making the sound. It's totally normal and doesn't hurt you. Sometimes, especially in bigger joints like your knees, shoulders, or ankles, the sound can also happen when the stretchy tissues that connect your bones (ligaments and tendons) move slightly and then snap back into place.

After you crack your knuckles, you can't usually do it again right away. You have to wait a bit. That's because the gas bubbles in your joint fluid have already popped, and it takes a little while for them to build up again. While cracking your knuckles doesn't give you arthritis, doing it too much might cause some problems. Doctors say that cracking them too often could make your joints a little wobbly and might even make your grip weaker. Also, if the stretchy tissues in your joints keep snapping over your bones, they can get irritated and sore.

When Joint Popping Might Mean Something More

Sometimes, a pop in your joint is just like cracking your knuckles, nothing to worry about. But other times, it can be a sign of something else. As we get older, the cushiony stuff in our joints, called cartilage, can start to wear down. This cartilage helps your bones move smoothly. When it gets thin or uneven, the bones can rub together, and that can make a grinding or popping sound. This is different from the pop you get from gas bubbles. If this grinding sound happens along with pain, it could be a sign of osteoarthritis. This is a type of joint problem that's more common in older people, but younger people can get it too, especially after a joint injury. If your joints hurt, especially in the morning or after you've been sitting still for a while, feel wobbly, or are hard to move, it's a good idea to see a doctor.

Long-term use of melatonin, a popular over-the-counter sleep supplement, has been linked to a higher risk of heart failure and early death in adults with insomnia, according to new research published on Monday.

While the findings don’t show that melatonin directly causes heart problems, experts suggest that the need to rely on it regularly to fall or stay asleep could point to hidden heart-related issues.

What Is Melatonin?

Melatonin is a naturally occurring hormone that plays a key role in regulating sleep. Often called the body’s “sleep hormone,” it helps control the circadian rhythm, which is the internal clock that tells us when to sleep and wake up. The pineal gland in the brain produces melatonin, but many people now turn to melatonin supplements to improve sleep quality.

According to the Cleveland Clinic, these supplements are often marketed for managing insomnia or jet lag. While melatonin can help set a natural sleep cycle, it is not meant to diagnose, treat, or prevent any medical condition. In several countries, including the United States, it is available over the counter without a prescription.

Can Melatonin Lead To Heart Issues?

As over-the-counter supplements are not strictly regulated, melatonin products can vary widely in their concentration and purity. This inconsistency may contribute to different long-term effects on the body.

To assess the potential risks, researchers examined health data from more than 130,000 adults diagnosed with insomnia who had used melatonin for at least a year. They compared these individuals with others who also had insomnia but did not take the supplement.

The results were concerning. People who used melatonin for 12 months or longer showed about a 90 percent higher risk of heart failure over a five-year period than those who did not.

“Melatonin supplements are widely considered a safe and ‘natural’ solution for better sleep, so it was striking to see such strong links to serious health outcomes even after accounting for other risk factors,” said study author Ekenedilichukwu Nnadi, as quoted by The Independent.

Heart failure occurs when the heart cannot pump enough oxygen-rich blood to meet the body’s needs, which can be life-threatening. The study also observed a similar rise in heart failure risk among people who had at least two melatonin prescriptions filled 90 days apart. In fact, melatonin users were found to be 3.5 times more likely to be hospitalised for heart failure compared to non-users, according to the research, which was presented at the American Heart Association’s 2025 Heart Disease and Stroke Statistics meeting but has not yet been peer-reviewed.

So, Is Melatonin Safe To Consume?

To understand the implications, we spoke with Dr. Khushboo Hatekar, Assistant Professor of Neurology at Dr. D.Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune. She explained that long-term dependence on melatonin often points to underlying conditions such as cardiovascular stress caused by chronic insomnia.

“Insomnia itself raises blood pressure, stress hormones, and inflammation, all of which strain the heart. So, prolonged melatonin use may serve as a signal of hidden heart issues rather than being the direct cause,” she said.

Dr. Hatekar also cautioned against taking melatonin regularly without medical supervision. “Most guidelines recommend melatonin for short-term use, mainly for jet lag or specific sleep disorders,” she added. However, current evidence highlights the need for more detailed clinical studies to determine whether extended use poses a cardiovascular risk.

While short-term use of melatonin appears safe for most people, taking it continuously for a year or longer may increase the likelihood of heart failure and related complications. Both patients and doctors should carefully weigh the benefits and monitor heart health if the supplement is used over an extended period.

Do you struggle to concentrate and find it hard to focus on one task for more than a few minutes? You might be dealing with what psychologists are calling “popcorn brain”. The name may sound lighthearted, but experts say the condition is real and growing more common.

With constant use of smartphones, laptops, tablets, and televisions, people, especially teenagers and young adults, are spending most of their waking hours in front of screens. This nonstop exposure is leading to what’s now known as Popcorn Brain Syndrome, a modern problem that is affecting focus, attention span, and emotional balance.

To understand the condition better, we spoke with Dr. Astik Joshi, Child, Adolescent, and Forensic Psychiatrist at Veda Clinic, Rohini, and Fortis Hospital, New Delhi.

What Is Popcorn Brain Syndrome?

Popcorn Brain Syndrome refers to a state where the brain becomes so used to fast, constant digital stimulation that it struggles to adjust to slower, real-world activities. Much like popcorn rapidly popping in a microwave, the brain starts craving constant bursts of new information. When the pace slows down, like during reading or in-person conversations, the mind becomes restless, impatient, or easily bored.

According to Dr. Joshi, “Popcorn brain syndrome isn’t a formal medical term or diagnosis. It’s a phrase used to describe how our minds can’t stay still and keep jumping from one thought to another, just like popcorn pops when exposed to heat.”

However, now, the term “popcorn brain” has been gaining attention in mental health circles. It was first introduced by David M. Levy, Ph.D., a computer scientist at the University of Washington, who described it as a state where people become so used to multitasking online that real life feels too slow and uninteresting.

The syndrome is not limited to social media enthusiasts or office workers glued to their emails, the constant pings and alerts from our devices make this phenomenon relatable to almost everyone.

How Does Popcorn Brain Syndrome Affect Your Brain?

Popcorn brain can cause difficulty focusing, frequent distraction, restlessness, and poor time management. Dr. Joshi explained that screen time creates a continuous flow of stimulation that makes our thoughts and emotions jump around, causing mental and emotional unease.

“This constant mental restlessness can have a negative impact on teenagers and young adults,” he said. “Their brains are still developing, and they haven’t yet built full control over their emotions and thoughts. Continuous exposure to screens interferes with healthy brain development and emotional regulation.”

According to a Healthline report, people experiencing popcorn brain also often complain of eye strain, headaches, blurred vision, and neck or shoulder pain, symptoms that overlap with computer vision syndrome (CVS) or digital eye strain.

Social Media Is to Blame for Popcorn Brain Syndrome

It is no surprise that social media plays a major role in this growing issue. Studies show that frequent use of phones, computers, and apps like Instagram can deeply affect our ability to concentrate.

One study published in Scientific Reports found that simply having a smartphone nearby reduced participants’ focus during attention tests. When their phones were switched off or placed out of sight, their concentration levels improved noticeably.

Another study by Stanford University showed that constantly shifting attention between screens—whether social media, phones, or TV, makes it harder to complete even simple tasks. In a 2022 survey conducted by King’s College London, half of adults in the U.K. admitted they felt their attention spans had shortened significantly over time.

How To Cure Popcorn Brain Syndrome?

To break the cycle of checking your phone every few minutes and give your brain a reset, Dr. Aditi Nerurkar, Harvard Physician, suggests four simple practices:

Limit your scrolling time

Restrict yourself to no more than 20 minutes twice a day for social media or non-essential phone use. “Use your phone only for calls, messages, and important emails,” she advises. To keep track, set a timer whenever you scroll.

Turn off notifications

Disable push alerts and pop-ups that tempt you to pick up your phone unnecessarily.

Keep your phone away while working.

Place your smartphone at least ten feet from your desk so you can focus on tasks. “Do the same at home, especially when you’re spending time with family,” says Dr. Nerurkar.

Don’t sleep next to your phone

Avoid placing your device on your bedside table. This prevents you from checking it right before bed or first thing in the morning. Let loved ones know to call if there’s an emergency, and keep the ringer on instead.

Dr. Nerurkar acknowledges that cutting down on screen time won’t be easy at first. To make it easier, replace the habit with small, grounding activities, like grabbing a notepad, fidget toy, or book, or simply walk around for a minute or two when you feel the urge to reach for your phone.

Recalled Pasta Meals Listeria: A Listeria outbreak has taken six lives across 18 U.S. states in the past week, according to the Centers for Disease Control and Prevention (CDC). Two additional deaths have been reported in connection with a nationwide Listeria outbreak linked to recalled pasta salads and prepared meals, as noted by Emegypt.

From symptoms and affected products to safety measures, here is everything you need to know about the ongoing Listeria outbreak in the U.S. As the Listeria pasta outbreak spreads further, here’s a look at what it involves and how to prevent this potentially fatal infection.

What Is Listeria Pasta Outbreak?

The illness stems from a foodborne bacterial infection. When the bacterium Listeria monocytogenes contaminates food and causes poisoning, it is known as a Listeria outbreak, according to the Cleveland Clinic. The CDC has confirmed 27 Listeria cases across 18 states, with 25 hospitalizations so far. The source has been traced to Listeria monocytogenes found in precooked pasta meals produced by Nate’s Fine Foods Inc.

Listeria Recalled Pasta Meals: What Is Listeria Monocytogenes?

Listeriosis is a type of food poisoning caused by the bacterium Listeria monocytogenes, often referred to simply as “Listeria.” The Cleveland Clinic notes that most people experience mild symptoms such as fever, headache, nausea, or diarrhea. However, for individuals with weakened immune systems or those over the age of 65, the infection can lead to serious or even life-threatening complications.

Pregnant women are also at high risk since the infection can pass to the baby during pregnancy or delivery, leading to miscarriage, premature birth, or severe health problems for the newborn.

Listeria Outbreak: What Foods Have Been Recalled For Listeria?

According to USA Today, the following items have been recalled due to possible Listeria contamination:

• Marketside Grilled Chicken Alfredo (32.8 oz)
• Sprouts Farmers Market Smoked Mozzarella Pasta Salad
• Giant Eagle Smoked Mozzarella Pasta Salad
• Kroger Deli Bowtie and Penne Pasta Salads
• Scott & Jon’s Shrimp Scampi with Linguini Bowls (9.6 oz)
• Trader Joe’s Cajun Style Blackened Chicken Breast Fettuccine Alfredo (16 oz)
• Albertsons Store-Made Deli Pasta Salads
• Marketside Linguine with Beef Meatballs & Marinara Sauce (12 oz)

Listeria Outbreak: How To Prevent The Deadly Infection?

The U.S. Food and Drug Administration (FDA) recommends three key steps to reduce the risk of Listeria infection:

Maintain Proper Cooling Temperatures

Keeping food cold slows the growth of Listeria. If your refrigerator doesn’t have a digital temperature display, use a thermometer to check and adjust the settings. Place another thermometer in the freezer for accuracy.

• Your refrigerator should be at 40°F (4°C) or below.

• Your freezer should be at 0°F (-18°C) or below.

Consume Ready-to-Eat Foods Promptly

The longer leftovers or ready-to-eat meals stay in the refrigerator, the greater the chance that Listeria may grow. If a food item starts to smell, taste, or look unusual, it’s best to discard it.

Keep Your Refrigerator Clean

Regular cleaning helps prevent bacteria from spreading. Wipe spills as soon as they occur, this prevents Listeria from multiplying and contaminating other items. Wash shelves and walls with hot water mixed with mild dish soap, rinse thoroughly, and dry with a clean cloth or paper towel.
