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.
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.
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.

During the COVID-19 pandemic, the SARS-CoV-2 virus had a significant impact on the eyes, causing conjunctivitis (pink eye), with red, itchy, watery, or painful eyes.
A new study now shows that eye symptoms may also be key in understanding the severity of long COVID, a collection of symptoms that last three months or longer after your first COVID symptoms.
The new study, published in the journal Clinical Ophthalmology, showed that the new onset of eye symptoms in people with long COVID may be an indicator of more severe disease.

Researchers from the Yale School of Medicine analyzed survey data from 595 adults who self-reported having long COVID in surveys conducted from May 2022 to October 2023. They found that nearly 60 percent of people reported new-onset of ocular symptoms.
The findings suggest that ocular symptoms in long COVID may be interpreted as vision-related manifestations that cluster with systemic post-COVID conditions. The symptoms include a new onset of :
Notably, individuals with ocular symptoms reported:

Long COVID includes a wide range of symptoms or conditions that may improve, worsen, or be ongoing. While anyone who gets COVID-19 can develop Long COVID, studies have shown that some groups of people are more likely to develop Long COVID than others, including:
While many of the Long COVID conditions remain to be fully recognized, some people have more than one symptom that can be moderate to severe, and also impact the quality of life. According to the US CDC, they include:

A Parliamentary Standing Committee on Health and Family Welfare has raised serious concerns about growing doctor burnout, especially among junior and senior resident doctors, and warned that it is now affecting both doctor well-being and patient safety. Noting that overworked doctors are a risk for patient safety, the panel said that fatigue-driven errors and burnout could compromise care.
To tackle this, the committee recommended that the government introduce and strictly enforce a formal “Clinical Duty Hours Regulation” policy. This should mandate fixed rest periods and monitored duty rosters, with oversight mechanisms to prevent violations, stated the panel in its 172nd report presented before the Parliament.
The recommendation comes amid growing concern over long, unregulated shifts in teaching hospitals, where residents often work extended hours with limited rest.
The panel warned that such conditions not only increase the likelihood of clinical mistakes but also contribute to burnout and mental health stress among young doctors.
The Panel noted that due to persistent human resource shortages, the working hours of junior and senior residents doctors often stretch from 24 to 36 hours. This increases risk of clinical errors and burnout, thereby compromising patient safety. Thus it recommended a mandatory working-hour regulatory framework:
However, it noted the contractual engagement must not substitute regular appointments, as excessive reliance on contractual staff may dilute institutional accountability and continuity.
Instead, the panel has recommended adopting a "Total Support model for medical professionals" to attract and retain qualified doctors and specialists in the public health system.

Burnout is distinct from depression, which influences every aspect of life and often involves persistent thoughts of hopelessness or worthlessness. Burnout typically involves limited manifestations to the work environment, although its impact can resonate into other areas.
Symptoms of Burnout
1. Exhaustion: Prolonged mental and physical depletion of your energy levels.
2. Depersonalization: Cynicism and lack of concern creep into relationships and communication.
3 Reduced Personal Achievement: Your work loses worth, and you may feel you are not up to standards, giving in to frustration and reduced originality.
These signs frequently coincide with physical signs (headaches, muscle pain, sleeplessness), emotional signs (self-doubt, loneliness, unhappiness), and behavioral signs (social withdrawal, outbursts of anger, abandonment of obligations).

Continuing the legacy of football legend Joe Thompson, his wife Chantelle revealed she is pregnant with his baby after IVF treatment using frozen embryos.
Joe Thompson died in 2025 after developing cancer for a third time - beating the illness twice.
But after the former Manchester United star was diagnosed with Hodgkin Lymphoma for a third time, which had spread to his lungs, he died aged 36.
"It just means absolutely everything. I know it's never going to replace Joe obviously. Joe's Joe. But to be able to bring his baby into the world again is beautiful," Chantelle said.
She said Joe had two visions of their family with a baby boy before he died, and he even gave her the name for the baby boy he predicted, and she got pregnant on her first attempt of IVF after he had died.
Egg freezing, also known as oocyte cryopreservation, is an option that has gained significant traction in recent years. It offers women the ability to pause their biological clock and preserve the possibility of having children in the future.
Egg freezing takes a woman's unfertilized eggs from her ovaries and stores them at sub-zero temperatures to be utilized later. It is made to enable women to keep their fertility intact, especially if they are not yet ready to have a baby.
Dr. Pavithra M, Obstetrician, Gynecologist, and Infertility Specialist, told HealthandMe that the workup begins with hormone workup and evaluation of various parameters, such as age, body mass index (BMI), and ovarian reserve.
"On the second day of the menstrual cycle, baseline ultrasound scanning is performed to assess the number of follicles; thereafter, various tests of blood are conducted to assess hormone levels. If a woman's parameters are all normal, then she is administered hormonal injections for about 10-12 days."

It causes ovarian hyperstimulation and multiple mature eggs, monitored through ultrasound scans. A trigger shot is administered once the follicles have reached optimal size to help with final egg maturation. It takes 34-35 hours from the trigger shot, wherein eggs are retrieved by minimally invasive procedures under general anesthesia.
"Using a transvaginal ultrasound probe with a needle, each follicle is punctured, and the follicular fluid is aspirated. The retrieved eggs are then screened for quality before undergoing vitrification—a rapid freezing technique that minimizes ice crystal formation and cellular damage," Dr. Pavithra added. The eggs are then stored in liquid nitrogen tanks for long-term preservation.
While egg freezing is possible at various stages of life, experts recommend doing it at an optimal age -- in the late 20s or early 30s when the eggs are of higher quality-- for better outcomes.
