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.

High blood pressure (BP) has become a public health problem that is driving cardiovascular diseases like heart attacks and strokes globally. While medications are important to keep hypertension under control, lifestyle changes and healthy practices are also crucial.

Several global health guidelines recommend regular physical activity, but adhering to exercise programs daily becomes a challenge for many people. But in the overtly busy schedules, sparing 10 minutes for an exercise regimen can be easier than travelling to the gym.

A large randomized clinical trial, published in the Journal of the American College of Cardiology (JACC), has proved that a traditional Chinese mind-body practice — baduanjin — may help lower blood pressure, that too, without any equipment.

Baduanjin is a slow, structured movement, focused on deep breathing and meditation.

Importantly, the clinical trial proved that the ancient Chinese technique could lower BP as effectively as brisk walking.

In people practicing baduanjin, BP reductions were seen after three months and were sustained for one year.

"Given its simplicity, safety, and ease with which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible, and scalable lifestyle intervention for individuals trying to reduce their blood pressure," said Jing Li, Director, National Center for Cardiovascular Diseases in Beijing, China.

Baduanjin: The 10 Minute Routine

Baduanjin is a standardized eight-movement sequence that integrates aerobic, isometric, flexibility, and mind-body components.

It has been in practice for centuries and commonly performed in community settings across China. The routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction.

Because it is low- to moderate-intensity, it is considered safe and accessible for many adults.

The Clinical Trial

A team of Chinese researchers led the first large, multicenter randomized trial to look at the impact of baduanjin on blood pressure.

They followed 216 participants, aged 40 years or older, across seven communities to determine changes in 24-hour systolic BP from baseline to 12 and 52 weeks.

Compared to people indulging in self-directed exercise, practicing baduanjin five days a week reduced

• systolic blood pressure by approximately 3 mg Hg
• systolic blood pressure by 5 mg Hg.

Notably, the benefits were sustained even without ongoing monitoring, a key challenge for many lifestyle interventions that struggle to maintain long-term adherence outside structured programs.

"Baduanjin has been practiced in China for over 800 years, and this study demonstrates how ancient, accessible, low-cost

approaches can be validated through high-quality randomized research," said Harlan M. Krumholz, Editor-in-Chief of JACC and the Harold H. Hines, Jr Professor at the Yale School of Medicine.

"The blood pressure effect size is similar to that seen in landmark drug trials, but achieved without medication, cost, or side effects. This makes it highly scalable for community-based prevention, including in resource-limited settings," they added.

How To Practice Baduanjin

• Stand upright with your feet shoulder-width apart and keep your movements slow and controlled.
• Coordinate each motion with steady, deep breathing, inhaling and exhaling smoothly as you move.
• Move through the traditional eight postures in sequence, focusing on posture, balance, and relaxation rather than speed or force.
• Practice for about 10 to 15 minutes a day in a quiet space, maintaining calm attention throughout.

Are you a working professional? Have you been diagnosed with endometriosis? Worried about how this condition can impact your career? Well, don’t panic! We give you vital tips to manage the symptoms of endometriosis without compromising your professional aspirations. Dr. Kanika Gera Thakral, Consultant – Obstetrics & Gynaecology, Motherhood Hospitals, Greater Noida, spoke about the effects of endometriosis on working women and what women can do to not let the pain take a toll on their work life.

What is endometriosis?

Endometriosis happens when tissue similar to the lining of the uterus grows outside the uterus. These tissues commonly develop on the ovaries, fallopian tubes, or the pelvic lining. Endometriosis affects many women and can impact their daily lives, including their ability to work comfortably. Many women continue their professional responsibilities despite experiencing severe discomfort, fatigue, and pain.

Raising awareness about the condition and encouraging supportive workplaces can help women manage both their health and career more effectively. Since it is a progressive disorder, timely intervention remains key to managing it. In many cases, women live with symptoms for several years before receiving the correct diagnosis, which can delay treatment and affect their quality of life.

The workplace challenge

Many working women who are diagnosed with endometriosis tend to experience symptoms such as pelvic pain, cramps, fatigue, nausea, and heavy menstrual cycles. These symptoms can make it difficult to maintain productivity at work, especially during flare-ups. Hence, women will be unable to concentrate on work or finish the tasks. Some may miss deadlines and meetings due to the painful symptoms. Women will have to skip going to work when the symptoms are intense and will have to rest at home. So, women living with endometriosis may face interruptions in their career growth and reduced working hours. But don’t worry, it is possible to manage this condition and give your best at work.

1. Long working hours, prolonged sitting, workplace stress, irregular meals, and lack of adequate rest can sometimes worsen symptoms of endometriosis.
2. Apart from physical discomfort, the condition can also affect emotional well-being. Living with chronic pain may lead to stress, anxiety, or frustration, which can indirectly impact workplace confidence and productivity.

Strategies for managing work and endometriosis

It is necessary for women with endometriosis to go for regular check-ups and follow-ups with the doctor. Women can continue to pursue their professional goals by adopting practical strategies to manage the condition. Open communication with employers when it comes to flexible schedules can help overcome stress and anxiety. Women should have access to remote working to avoid unnecessary travel due to pain.

The work-from-home option can be given to the women when needed by them. Planning demanding tasks during times of higher energy and maintaining a balanced daily routine can also improve productivity at work. Women should make sure to keep essential medications, a heating pad, or comfort aids at their desk to be able to relieve sudden discomfort. Likewise, using ergonomic seating or maintaining good posture while working may reduce pelvic and even back discomfort. Women should also connect to support groups that help to provide emotional reassurance and useful coping strategies that include yoga and meditation.

Lifestyle habits also play an important role. Regular physical activity, adequate sleep, stress-management techniques such as yoga or meditation, and following an anti-inflammatory diet rich in fruits, vegetables, whole grains, and healthy fats may help reduce flare-ups.

Treating endometriosis

Treatment is particularly based on the severity of symptoms. Women will be advised lifestyle modifications such as regular exercise, stress management, and an anti-inflammatory diet. Non-steroidal anti-inflammatory drugs may help reduce discomfort. Hormonal therapies may also be used to control symptoms. Some women will be advised to undergo laparoscopy to remove endometriotic cysts. Minimally invasive surgery can help remove lesions and restore pelvic anatomy, which may also improve fertility in some cases. In advanced cases, surgery can be recommended to women.

With timely care and supportive workplaces, women can pursue their ambitions without letting endometriosis interfere with their careers.

Four years after suffering from a rare neurological condition known as Stiff-Person Syndrome, Céline Dion, known for power ballads like My Heart Will Go On and Because You Loved Me, has announced her return to the stage.

The incurable condition had affected her singing voice and even her ability to walk.

In a message on her Instagram page, the singer announced plans to play a 10-night residency at the 40,000-capacity Paris La Défense Arena in September and October.

Calling her comeback "the best gift of my life", 58-year-old Dion said: "I'm doing great, managing my health, feeling good. I'm singing again, even doing a little bit of dancing.

"I'm so ready to do this. I'm feeling good, I'm strong, I'm feeling excited, obviously, [and] of course, a little nervous," she said, while thanking her fans for the “prayers and support, kindness and love”.

What Is Stiff Person Syndrome

Stiff-Person Syndrome is a neurological disease caused by the signals from the nerves to the muscles not working properly. It affects an estimated 8,000 people worldwide.

It is also an autoimmune is a neurological disease caused by the signals from the nerves to the muscles not working properly. It affects an estimated 8,000 people worldwide.

It is also an autoimmune condition, that is linked to diseases such as type 1 diabetes, thyroiditis, vitiligo, and pernicious anemia.

For some, it can be debilitating. SPS is progressive, meaning it gets worse over time. There is no known cure.

Common symptoms may include:

• Stiff muscles in the torso, arms, and legs
• Greater sensitivity to noise, touch, and emotional distress, which can set off muscle spasms

The condition is also more common among women than men, and affects people between the ages of 20 and 60.

While there is no known cure for SPS, current treatments such as intravenous immunoglobulin (IVIg) can help manage the symptoms.

Stiff-Person Syndrome: Celine Dion’s Diagnosis

Dion announced her diagnosed with Stiff Person Syndrome (SPS) in December 2022 in an emotional Instagram video. The condition had affected "every aspect of my daily life", she told her fans.

The best-selling artists of all time began noticing her symptoms, such as feeling "a little spasm" while performing on stage. She found her “voice was struggling", BBC reported.

Even though she experimented with her singing to ease the stress on her vocal cords, her condition worsened. She also began facing difficulties while walking.

"It's like somebody is strangling you. It's like somebody is pushing your larynx [or] pharynx," she told NBC News.

Determined to get back on her feet and sing, worked "all my body and soul, from head to toe, with a medical team", French Vogue magazine reported.

"Five days a week, I undergo athletic, physical, and vocal therapy. I work on my toes, my knees, my calves, my fingers, my singing, my voice."

The intense workouts enabled her to make a comeback at the 2024 Paris Olympics, singing Edith Piaf's classic Hymne à l'Amour from the Eiffel Tower.
