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.

In a country where diseases have become a daily topic of discussion, hypertension is gradually increasing behind closed doors. Also referred to as “the silent killer”, this ailment is notorious for making its presence known without symptoms, unlike many health conditions. By the time it is discovered, it may have already begun to affect vital organs.

Diabetes: A Comorbidity Giving Rise to This Vicious Cycle

One of the most prevalent comorbidities of hypertension is diabetes; together, the two create a difficult combination of chronic conditions affecting a patient's overall health. Diabetes causes high blood glucose (sugar) levels that, over time, damage blood vessels by reducing their ability to stretch or expand. When combined with the pressure caused by hypertension, these already compromised blood vessels can deteriorate rapidly, resulting in further damage.

The combined effects of diabetes and hypertension significantly increase the risk of heart-related complications, such as enlargement of the heart muscle, a reduced ability of the heart to pump blood effectively, and heart failure. Thus, the two conditions create a vicious cycle and emphasise the need for prompt diagnosis and treatment.

According to Dr Ameet Soni, AVP Medical Affairs, CORONA Remedies, “Hypertension and diabetes mellitus (DM) are two of the most common cardiometabolic disorders, often occurring together, and each exacerbates the impact of the other. When combined, these conditions significantly increase the risk of complications such as cardiovascular, cerebrovascular, and renal damage, particularly when symptoms are not identified early or when treatment adherence is inadequate. Minimising the risk of these complications depends on early identification, proactive risk assessment before diagnosis, and long-term adherence to treatment regimens for controlling blood glucose levels and blood pressure.”

According to Dr Manoj Chawla, Diabetologist, P.D. Hinduja Hospital and MRC, Khar, Mumbai, “These diseases are also termed ‘silent partners’, indicative of both their association and the silent damage they cause to bodily functions. The connection between these diseases in India is quite common owing to several factors, including a sedentary lifestyle, poor nutrition, obesity, excessive stress, and a lack of proper diagnosis. Individuals suffering from diabetes have twice the risk of developing hypertension compared with healthy individuals. Since both diseases are asymptomatic in many cases, patients may only discover them when complications arise. Early diagnosis of hypertension and diabetes is therefore vital. Tests such as blood pressure and blood glucose monitoring, weight management, proper nutrition, exercise, adequate sleep, and stress management all help to prevent these risks.”

Here are five alarming signs that your hypertension might be linked to diabetes.

1. Frequent Urination and Thirst: One of the earliest signs that hypertension may be associated with diabetes is frequent urination, accompanied by an abnormal increase in thirst. When blood sugar levels are high, the kidneys work overtime to filter and absorb excess sugar, leading to increased urine production. This, in turn, causes dehydration, prompting an increased thirst response.
2. Fatigue and Weakness: If you are experiencing unexplained fatigue or weakness, this could be a sign that your hypertension is coupled with diabetes. High blood sugar levels prevent glucose from entering the cells efficiently, leaving the body depleted of energy. Hypertension, in turn, places additional strain on the heart and circulatory system, leading to a further decline in overall energy levels.
3. Blurred Vision: The eyes are particularly vulnerable to the effects of both high blood pressure and diabetes. High blood sugar levels can damage the blood vessels in the retina, leading to diabetic retinopathy, which can cause blurred vision. Additionally, hypertension can further exacerbate this damage by increasing pressure within the blood vessels, resulting in worsening vision problems.
4. Numbness or Tingling in the Extremities: Diabetic neuropathy, a common complication of diabetes, causes nerve damage, particularly in the hands, feet, and legs. This nerve damage can lead to symptoms such as numbness, tingling or even a burning sensation in the extremities. When hypertension is present alongside diabetes, the blood vessels supplying the nerves may become compromised, exacerbating the symptoms of neuropathy.
5. Elevated Blood Sugar with Uncontrolled Hypertension: If your blood pressure is consistently high despite treatment or lifestyle changes, it could indicate an underlying issue, such as uncontrolled diabetes. Insulin resistance, which is common in type 2 diabetes, can worsen hypertension by increasing blood pressure due to factors such as weight gain and metabolic imbalances. When blood sugar levels are poorly managed, they can interfere with blood pressure regulation.

Early detection and intervention are key to managing both conditions and reducing the risk of complications. If you are experiencing any of the symptoms mentioned above or have a family history of either condition, it is vital to consult your healthcare provider. Regular screenings, lifestyle modifications and adherence to prescribed treatments can help control both hypertension and diabetes, improving your quality of life and preventing long-term complications.

Parkinson’s disease is characterized by slowness of daily activities, rigidity, and tremors with gait issues, commonly seen after the age of 45-50 years.

It is two times more common in men than women, though clinical features, response to the treatment, and prognosis are different in women as compared to men. From subtle early signs to how the condition develops over time, gender can shape the Parkinson’s journey in important ways.

Women usually experience Parkinson’s disease at a later age, but with faster progression of symptoms as compared to men. There is a need for more research in this space; however, we will try to shed light on these differences in Parkinson's trajectories in men and women based on available evidence.

Why Is Parkinson’s Less Common In Women?

Estrogen, a group of primary female sex hormones, is neuroprotective and protects dopaminergic neurons in women; women also have a higher baseline reserve of dopaminergic neurons. Hence, Parkinsonism is less common in women.

In the post-menopausal period, once this estrogen-related neuroprotective effect disappears, Parkinson’s symptoms progress rapidly. Motor symptoms emerge later in women with tremors, rigidity, and gait disturbances being more common and severe. Freezing of gait and postural instability with falls are more common in women.

Differences In Motor vs Non-Motor Symptoms

Non-motor symptoms like pain, fatigue, autonomic disturbances, sleep disorders, constipation, and mood disorders, including depression and anxiety, are more common and severe in women. Men with Parkinson’s disease have worse general cognitive abilities; however, women have worse visuospatial abilities.

Women with Parkinson’s receive less social support, lower quality care, attend medical appointments alone, and report more psychological stress. Women have a lower body mass index and higher bioavailability of levodopa, which makes them more susceptible to the side effects of levodopa, such as motor fluctuations and dyskinesia, which entail involuntary movements like fidgeting and writhing.

Why Personalized Treatment Matters

There is a clear need for personalized and tailored treatment. The different and distinctive clinical features in women, like later onset, higher tremors and rigidity, higher dyskinesia and motor fluctuations from drugs, and worse non-motor symptoms, require tailored, sex-specific treatment strategies rather than a “one-size-fits-all” approach.

Clinicians must give importance to the screening and management of non-motor symptoms in women, which are the main factors of their decreased quality of life. Women with this ailment go through longer delays in diagnosis and less access to specialists, highlighting a need for better healthcare access for women.

While HPV vaccines are most known for preventing cervical cancer, a top US doctor says they can also help curb the rising incidence of head and neck cancers.

According to Mikkael A. Sekeres, Chief of the Division of Hematology and Professor of Medicine at the Sylvester Comprehensive Cancer Center at the University of Miami, Human papillomavirus (HPV) — the same sexually transmitted virus that can infect the genital area and lead to cervical cancer — is now the greatest risk factor for head and neck cancer.

Writing in The Washington Post, Sekeres noted that HPV accounts for about 30 per cent of oropharyngeal cancer worldwide.

HPV is believed to be responsible for the recent rise in head and neck cancers, which include malignancies affecting the mouth and throat (oral cavity and pharynx), voice box (larynx), sinuses and nasal cavities, and salivary glands.

Sekeres said the US records about 60,000 new cases of head and neck cancers each year, while the global incidence is expected to rise by 30 per cent by 2030.

What Are The Risk Factors?

The expert noted that men develop oral cavity and pharynx cancers at approximately 2.5 times the rate of women.

Major risk factors include:

• Tobacco use, including smoking, secondhand smoke and smokeless tobacco
• Chewing areca nut, also known as betel quid
• Heavy alcohol consumption
• HPV infection

The Centers for Disease Control and Prevention (CDC) estimates that the high-risk HPV subtypes most associated with head and neck cancers are detectable in the mouths of 4 per cent of adults aged 18 to 69.

While a pap test detects early-stage cervical cancer in women, no such test exists for penile, anal, or head and neck cancers in men, which can worsen their survival rate.

HPV Vaccination Best Prevention Strategy

Thus, Sekeres said: “The best way to prevent the most common types of HPV is through vaccination, with two doses of the vaccine recommended for children at age 11 or 12, or starting as early as 9 years and up to age 26 for those who missed it as a child".

He noted that although the vaccine is approved for use up to age 45, it is generally less beneficial after age 26 because many individuals may have already been exposed to HPV. However, doctors can help determine whether vaccination may still be beneficial for adults.

Earlier this year, the European Cancer Organization also urged broader HPV vaccination regardless of gender.

“HPV affects everyone, regardless of gender. It can lead to cancers of the cervix, mouth and throat, anus and penis. This is why universal protection is so important,” the organization said in a social media post.

HPV Vaccine Can Boost Cancer Risk

A 2026 study published in JAMA Oncology found that boys and men who received the HPV vaccine between the ages of 9 and 26 were nearly 50 per cent less likely to develop cancers of the head and neck, esophagus, anus, or penis.

The findings, based on data of more than 510,000 boys and men, highlight the importance of vaccinating all children and adolescents against HPV, said Taito Kitano, first author of the study and a researcher at Nara Prefecture General Medical Center in Japan.

“Children, adolescents, parents and health care workers should be more informed about the expected benefits of the HPV vaccine, not just cervical cancer,” Kitano said.
