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.

Scromiting is taking up the space in headlines now. Before 2025 comes to an end, this single symptom caused by a deadly cannabis condition has got everyone talking about it.

The deadly cannabis hyperemesis syndrome (CHS), is now formally designated by the World Health Organization (WHO), and the unique and unusual symptom is scromiting: a mix of screaming and vomiting. Thanks to social media, this word is making a buzz and have distorted what people should actually know about the condition.

The WHO has formally named CHS in October, which was after a decision adopted by the Centers for Disease Control and Prevention (CDC) that will help doctors track the prevalence of the condition and get a better picture of adverse events.

Scromiting and CHS: How Did It Make A Big News?

The conversation reignited after a study published in the Journal of the American Medical Association in late November reported that CHS cases remain elevated. The study noted that cyclic vomiting is a related symptom and confirmed that emergency department visits tied to CHS saw a notable rise between 2016 and 2022, particularly in 2020 and 2021. During those two years, researchers identified 188 million emergency department visits among adults aged 18 to 35, with CHS appearing more frequently among heavy cannabis users.

The Origin Of CHS

CHS was first identified in Australia in 2004, yet nearly two decades later it remains poorly understood. It typically affects people who use marijuana daily or near daily for more than a year, leading to episodes of severe nausea, repeated vomiting, abdominal pain and a compulsive desire to take extremely hot showers or baths. Many patients report that heat temporarily eases their symptoms, although doctors say the relief is often short-lived.

What Are The Doctors Saying?

Dr Sam Wang, a pediatric emergency medicine specialist and toxicologist at Children’s Hospital Colorado, described treating patients who arrive exhausted and doubled over in pain after hours of vomiting, as reported by CNN. Many tell doctors they tried taking a scalding hot shower before coming to the hospital but found it offered little relief. The National Institutes of Health has said this hot water reliance appears to be a learned behavior that can become a compulsion.

Despite the surge in awareness, the term “scromiting,” a blend of screaming and vomiting, has sparked its own controversy. Some social media users argue the sudden buzz is exaggerated or anti-cannabis fearmongering. Others say the phenomenon has been known for years. Natashia Swalve, a neuroscience professor at Grand Valley State University, told Axios that “scromiting” is not a clinical term, just a catchy label that gains traction every few years. She warned that sensational language fuels confusion at a time when misinformation about CHS is already widespread.

Health experts say CHS episodes can last for days and recovery may take weeks or even months, depending on overall health, eating habits and whether the person stops using marijuana. Continuing to use cannabis can quickly trigger symptoms again. A study from George Washington University found that nearly half of surveyed patients had been hospitalized at least once because of CHS, and many reported using marijuana more than five times a day before symptoms began. Starting cannabis at an early age was linked to a higher likelihood of developing the condition.

The renewed scrutiny of CHS comes as the United States faces rising infections from norovirus, sometimes called “winter vomiting disease,” another illness known for causing sudden, intense vomiting. While unrelated, the overlapping symptoms have added to public confusion around what exactly is driving widespread reports of stomach distress.

Researchers emphasize that CHS is real, although many questions remain unanswered, including why hot showers feel soothing and how much cannabis use puts someone at risk. They say more clinical awareness is urgently needed. Better screening for cannabis use and recognizing symptom patterns could help reduce misdiagnosis and guide patients toward the only proven treatment: stopping marijuana use.

For years, people have joked about how women seem to enjoy showers that could probably cook noodles. If you are someone who loves cranking up the water temperature until the bathroom looks like a steam room, you may have wondered whether there is an actual reason behind it. According to UK surgeon and content creator Dr Karan Rajan, the answer lies in biology. Women are not simply choosing scalding showers for fun. Their bodies are wired differently, and that affects how they experience temperature.

Higher Core Body Temperature

Dr Rajan explains that, on average, women have a slightly higher core body temperature than men. It might sound like this would keep them warmer, but in reality, it does the opposite. When the core is warm but the surrounding environment is cool, that contrast makes cold air feel even colder. So a mildly chilly room may feel more uncomfortable for women, leading them to turn to hotter showers to compensate.

This idea has gone viral online. In a popular TikTok clip, creator couple Micah and Sarah joked about preparing for a shared shower. Micah pretended to train for the extreme heat by dipping his hand in boiling water. The internet quickly chimed in with comments like “My husband says I am training for hell” and “He calls it lobster time”. The jokes were relatable because many couples experience this temperature divide, but not many knew the science behind it until now.

Hormones Add to the Chill

Hormones play a major role too. Estrogen affects blood flow to the extremities, which includes hands, feet and even earlobes. Research shows that women’s extremities can be up to three degrees colder than men’s. Dr Rajan points out that this becomes more noticeable during ovulation when estrogen levels peak. Women on hormonal birth control may also experience increased sensitivity because estrogen stays higher for longer periods.

So even when the core stays warm, the toes and fingers may feel unusually cold. A very warm shower becomes a quick and comforting fix for this temperature imbalance.

Lower Metabolic Rates

Another biological factor is metabolic rate. Women generally have a lower resting metabolic rate than men, meaning they produce less body heat throughout the day. This naturally makes them feel colder and more drawn to hotter water while bathing. Women also tend to have more body fat and less muscle mass, which influences how the body responds to temperature changes.

What Doctors Say

Australian GP Dr Jasmina Dedic Hagan supports these findings, as reported in Body and Soul. She explains that women typically have warmer cores, cooler skin, and a higher layer of insulating fat around the body. On top of that, they have reduced circulation in the extremities because the body prioritises keeping reproductive organs warm. With less muscle mass, the body’s heat-producing brown fat does not function in quite the same way as it does in men.

So Is It Just Preference?

Not entirely. While some women truly enjoy the sensation of a very hot shower, much of it is tied to biology. From hormones to metabolism to circulation, several factors work together to make warmer showers feel soothing and sometimes even necessary. So the next time someone teases you about loving lava-level water, you can tell them it is simply science at work.

When you are burning up, even a simple shower can feel confusing. Should you cool your body quickly with cold water or soothe your aches with something warm? Fever is a natural defense mechanism, but the symptoms it brings can make you feel miserable. The right water temperature can help ease discomfort and support your recovery.

Below is a simple breakdown of how fever affects your body, followed by practical shower tips and additional ways to safely bring your temperature down.

How Fever Resets Your Body’s Thermostat

During an infection, your immune system releases chemicals called pyrogens. These signals tell the hypothalamus, which is your internal thermostat, to raise your core temperature. The added heat slows the growth of certain viruses and bacteria and helps immune cells work more efficiently.

This temperature rise is why you feel:

• Chills as your body works to reach the new set point
• Sweating when the fever begins to settle
• Faster heart rate and quicker breathing, which increase fluid loss

Knowing this matters because water that is too cold can trigger intense shivering, which drives your temperature higher. Water that is too hot can widen your blood vessels and increase sweating, which may worsen dehydration.

Cold, Lukewarm, or Hot: Which Shower Helps Most?

Each water temperature works differently with a fever. Understanding these differences helps you choose what your body needs at that moment.

Cold showers cool your skin quickly. They may feel refreshing if you are overheated, but they often trigger shivering. That shivering can raise your core temperature and is especially risky in children.

Lukewarm or tepid showers are the safest choice for most people with fever. This temperature allows gentle heat loss through the skin without causing shivering. It helps you cool down gradually while keeping your body comfortable.

Warm or hot showers can help relieve muscle aches or sinus congestion, especially for adults. However, they can increase sweating and may slightly raise your temperature. Avoid them if you are already overheated or dehydrated.

Simple Shower Tips When You Have a Fever

• Start with lukewarm water to safely reduce temperature and ease discomfort.
• If you feel flushed and sweaty, splash cold water only on pulse points such as the wrists and neck.
• Use warm showers only for congestion relief and follow up with hydration and light clothing.
• If you feel dizzy, sit on a chair outside the shower and let steam fill the bathroom while you take a gentle sponge bath.

Other Safe Ways to Bring Down a Fever

Rest

Your body is already working hard to fight the infection. Light activity can raise your temperature further, so give yourself time to rest and recover.

Stay Hydrated

Fever increases the risk of dehydration, especially if you have vomiting or a poor appetite. Sip water, oral rehydration solutions, or electrolyte drinks. Chilled fluids can also help lower your temperature.

Stay Cool

Keep your room slightly cool and wear loose, breathable clothing. If you have chills, use a light blanket but avoid overheating. You can place a cool cloth on your forehead or under the arms for short intervals.

Medication

Over the counter fever reducers like acetaminophen and ibuprofen can safely lower fever. Always follow dosage guidelines. Avoid aspirin in children because it can lead to Reye's syndrome.

What Not to Do

• Do not take cold showers or ice baths because they trigger shivering and can raise your temperature.
• Avoid alcohol rubs since the alcohol can be absorbed through the skin.
• Do not take extra doses of fever medicine thinking it will work faster.
• Always read medication labels carefully to avoid accidental overdosing.
