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.

Even as injectable aesthetic procedures are gaining popularity as "cosmetic" treatments in beauty clinics and wellness centers across the country, the Central Drugs Standard Control Organisation (CDSCO) has tightened rules around cosmetic use.

In a new public notice issued this week, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.

"Cosmetic means any article intended to be rubbed, poured, sprinkled or sprayed on, or introduced into, or otherwise applied to, the human body," the notice said.

It added that cosmetics are for "cleansing, beautifying, promoting attractiveness, or altering the appearance."

Thus, "products supplied in the form of injectable preparation do not fall under the definition of cosmetics. No cosmetic is permitted to be used as injection by consumer/professionals/aesthetic clinics," the notice added.

What Can No Longer Be Done

The new rules bar professionals and stakeholders from using or manufacturing any cosmetic product intended for injection or medical purposes.

The move also seeks to curb misleading advertising and unauthorised cosmetic practices by clinics and individuals.

The regulator also warned against misleading claims and the use of prohibited ingredients in cosmetic products, saying such violations attract action under the Drugs and Cosmetics Act and Cosmetics Rules, 2020.

"Use of prohibited ingredients in cosmetic products, misleading claims on label, use of cosmetics for treatment, and application of cosmetics through injection attracts violations of the said Act & Rules," the notice said.

The regulator stated that no person shall alter, obliterate, or deface any inscription made by the manufacturer on the container or label of the product intended for use as a cosmetic.

The notice added that the list of generally not recognised as safe (GNRAS) and restricted ingredients is published by the Bureau of Indian Standards (BIS).

It has also encouraged the public and users to report any instance of misleading claims or violations through email and state licensing authorities.

Why Injectable Beauty Clinic Therapies Are Under Scanner

The move follows several incidents of sub-standard cosmetic products found to be sold in the market, ranging from Botox parties in upscale salons to glutathione “skin whitening” drips offered in local aesthetic clinics.

Social media trends, celebrity endorsements, and growing demand for “preventive anti-ageing” treatments among younger consumers have driven the market for injectable beauty products, especially Glutathione drips, as well as detoxifying therapies, in the country.

Medical experts have also been raising concerns over their long-term safety and efficacy. As per experts, unregulated injectable procedures carry risks ranging from allergic reactions and infections to liver and kidney complications in extreme cases.

The new norms, thus, are part of the government's plans to strengthen the regulatory mechanism for cosmetics.

The government is also reportedly planning to designate a Central Cosmetics Laboratory to test cosmetic samples and may also designate any laboratory under its control for testing, according to Mint.

In addition, manufacturers will have to keep details and records of each batch and raw materials. Records are to be maintained for three years after the expiry of each batch. Imported cosmetic products shall bear a code number as approved by the State Licensing Authority.

Amid continuing heatwave conditions in northern India, prolonged exposure to extreme temperatures can trigger serious and potentially fatal medical emergencies, particularly among elderly individuals and cardiac patients, according to an expert.

The India Meteorological Department (IMD) has warned of severe temperatures across several states.

"Heat wave to severe heat wave conditions likely to continue to prevail over northwest & central India during the week and over East India during the next 5 days," the IMD said, in its latest update on May 20.

It added that severe heat conditions will persist for at least the next 72 hours across Delhi-NCR, Rajasthan, Uttar Pradesh, Punjab, and Haryana. Temperatures in several cities are expected to touch 47°C to 48°C, with Banda currently emerging as the hottest place in the country.

Dr. Vaibhav Mishra, Senior Director & Head, CTVS, Max Super Speciality Hospital, told HealthandMe that heat-related illnesses are not limited to discomfort or dehydration alone, and can rapidly worsen if early warning signs are ignored.

There are two major heat-related illnesses that people must understand so that timely precautions can be taken — heat exhaustion and heat stroke.

"Heat exhaustion is a milder and more common condition and typically occurs after prolonged exposure to high temperatures or intense physical activity in the outdoors," Dr. Vaibhav said.

Excessive sweating leads to significant loss of water and salts from the body, resulting in:

• dehydration,
• fatigue,
• dizziness,
• muscle cramps,
• weakness,
• headache,
• nausea.

"However, if heat exposure continues and the body’s cooling mechanisms begin to fail, the condition can progress to heat stroke, which is a medical emergency. In heat stroke, body temperature often rises above 104°F," Dr Vaibhav told HealthandMe.

What may initially appear as confusion, disorientation, or irrelevant talking can rapidly worsen into:

• altered consciousness,
• seizures,
• coma,
• death.

Dr Vaibhav said that to cool the body during extreme heat, the heart has to work harder and beat faster so that more blood can be directed towards the skin for heat dissipation.

"This places additional stress on an already weakened heart. Many cardiac patients are also on medications such as diuretics, which increase fluid loss and dehydration. Certain blood pressure medicines may blunt the body’s normal response to heat and delay warning symptoms," the expert told HealthandMe.

Dehydration further thickens the blood and, combined with increased cardiac workload, can significantly raise the risk of heart attacks, strokes, and dangerous rhythm disturbances.

How To Prevent Heat Stroke

Dr. Vaibhav stressed the critical need for early recognition of symptoms, especially in vulnerable individuals such as elderly people and cardiac patients, who are much more susceptible to heat-related complications.

Simple preventive measures can save lives. These include

• avoiding direct sun exposure during peak afternoon hours,
• maintaining adequate hydration,
• wearing loose cotton clothing,
• avoiding strenuous outdoor activity,
• never ignoring early symptoms such as excessive fatigue, dizziness, or confusion.

What Is Breast Cancer?

Breast Cancer occurs when abnormal cells in the breast grow uncontrollably, often beginning in the milk ducts or lobules. It remains the most commonly diagnosed cancer among women worldwide.

A recent study published in The Lancet Oncology projected that global breast cancer cases could rise to more than 3.5 million annually by 2050.

Major Lifestyle Risk Factors

In 2023, 28 percent of the global breast cancer burden (6.8 million years of healthy life lost to disability, illness, and early death) was linked to six potentially modifiable risk factors. These include:

• High red meat consumption
• Tobacco use and second-hand smoke exposure
• High blood sugar levels
• High body mass index (BMI)
• Excessive alcohol use
• Low physical activity
