Weight loss is usually considered a good thing, unexpected and extreme weight loss can be a sign of something in your body going very wrong. There could be some underlying issues that are causing your body to pull weight and nutrition from your muscles and body fat to keep you going. As you grow old, your limbs grow weaker, and same for your muscles, so you do lose some weight as you age, but losing a lot of it too quickly could be a sign of something much worse, Dementia. A recent study published in JAMA Network Open 2025 Cardiometabolic Trajectories Preceding Dementia in Community-Dwelling Older Individuals, has identified potential early indicators of dementia, including significant weight loss and specific digestive changes, appearing years before noticeable cognitive decline.

The study showed that people who later got dementia had their Body Mass Index, or BMI, go down faster than those who stayed healthy. BMI is a way to see if someone's weight is healthy for their height. This drop in BMI started happening many years before they were told they had dementia, sometimes as early as 11 years ago. Also, these people often started with a lower BMI to begin with. So, even though everyone's weight might change a little as they get older, the people who developed dementia had a much bigger and faster weight loss.

What Are Some Other Indicators Of Dementia?

Along with their BMI, the size of their waist also changed. People who ended up with dementia had smaller waist sizes, and this difference was noticeable about 10 years before they were diagnosed. This means that their bodies were changing in ways that showed up long before they or their doctors noticed any problems. So, not only was there weight loss, but also a loss of abdominal fat. This measurement is important because fat around the waist can be related to other health issues.

The study also found changes in their blood. Specifically, the "good" cholesterol, called HDL, went up in people who developed dementia. This increase happened about five years before they were diagnosed. It's tricky because HDL is usually seen as a good thing for your heart. But in this case, it seems like it might be a sign of changes happening in the brain. Scientists are still trying to understand why this happens.

Weight Loss Doesn’t Cause Dementia, Dementia Causes Weight Loss

When we see that people with dementia lose weight, it's easy to think that the weight loss is what caused dementia. But experts think it's the other way around. They call this "reverse causation." This means that the brain changes that cause dementia also cause people to lose weight. The brain changes can affect things like appetite, how the body uses food, and how people go about their daily lives. For example, people might forget to eat, have trouble making meals, or move around less.

While the study revealed a lot about different indicators of dementia and bodily changes, there are many limitations to the study. Everyone loses some weight as they get older. So, it's hard to know when weight loss is just a normal part of aging and when it's a sign of dementia. The study found that people with dementia lost weight faster, but it's still tricky to tell the difference in everyday life. Doctors need to look at other things, like memory tests, to figure out if someone's weight loss is a cause for concern.

If someone is losing weight without trying, and they're also having problems with their memory or thinking, it's important to talk to a doctor. It's not just about the weight loss; it's about the whole picture.

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.
