New Covid Strain: If you have recently been feeling unwell with a sore throat and fever, chances are you may have caught one of the new COVID strains spreading this autumn. The variants XFG, also being called Stratus, and NB.1.8.1, nicknamed Nimbus, are currently the most common types of coronavirus circulating across the UK and the US.

A recent study now suggests that one particular symptom caused by these new strains might last for life. While a hoarse or rough voice has emerged as a new and widely seen sign of infection, most other symptoms remain the same as those reported in earlier waves.

COVID Symptoms 2025: What Makes the New Strain Different?

As winter draws closer, many people are experiencing cold-like symptoms such as a runny nose, cough, and mild fever. In many cases, these are now being linked to COVID-19, as infection rates have risen to some of the highest levels seen this year.

The XFG strain, a sub-variant of the Omicron family, was first detected in January and has now become the dominant strain in the UK. Data from the UKHSA show that XFG accounts for around 38.3% of all COVID cases, while its subtype, XFG.3, makes up roughly 32.8%. Combined, the Stratus variant is now connected to more than 60% of global COVID cases, according to the WHO.

The Symptom That Could Last For Life

Loss of smell was one of the hallmark symptoms of earlier COVID infections. However, new research has found that for many people, this problem never completely goes away. A study led by the U.S. National Institutes of Health (NIH) discovered that two years after infection, nearly 80% of participants who had reported a change in their sense of smell still performed poorly in scent-recognition tests. Around one in four had severe smell loss or had lost the ability entirely.

Dr. Leora Horwitz, one of the study’s lead authors, explained that the loss of smell can deeply affect daily life and emotional health. She added that it can even become dangerous, since people may not detect smoke, gas leaks, or spoiled food. The problem occurs due to inflammation in the olfactory system triggered by the virus, she said.

The research compared thousands of individuals who had previously tested positive for COVID with those who had not. Participants were asked to identify 40 different scents in a multiple-choice test to measure the level of impairment.

Unique Symptoms of New COVID Strain in UK

The Stratus variant shows a slightly different pattern of illness compared to earlier versions. While symptoms like fever, cough, and fatigue remain common, doctors have noticed new signs such as a hoarse or raspy voice.

This strain follows Nimbus, which has been linked to extremely painful sore throats described as feeling like “razor blades.” Other possible symptoms of Stratus include shortness of breath, chest tightness, body aches, headaches, nausea, stomach upset, loss of appetite, brain fog, and sometimes a change in taste or smell, though the latter is now less frequent.

Health experts advise seeking medical help if any of these symptoms persist or worsen. Treatment options may include antiviral medicines, rest, and over-the-counter remedies for symptom relief.

Although global tracking of COVID cases has slowed since free testing ended, available data show infections have again surged to high levels. UKHSA reports that nearly 9% of all COVID tests conducted in early September were positive, the highest rate recorded since last November. Among samples taken at general practices, 10.8% tested positive, while hospital testing showed 8.9% positivity.

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.

Turns out, kidney disease is not just a ‘kidney’ problem anymore, it can, in fact, affect other organs, and could even be linked to other chronic conditions, revealed a recent study.

In the US, more than 1 in 7 adults are affected by chronic kidney disease or (CKD). This means that 35.5 million Americans are affected by it, and what makes it worse is that 9 out of 10 people do not even know they have CKD, says the Centers for Disease Control and Prevention (CDC). Amid all these numbers thrown on to, something more concerning lies. A recent Lancet study shows a link between the rise in CKD and other chronic diseases. We are talking about chronic conditions like diabetes, high blood pressure, and obesity.

So, What Does The Study Say?

The researcher saw that 14 percent of adults who are over the age 20 or older, which makes 788 million Americans who had CKD in 2022. The biggest problem is not the disease itself, but the unawareness. Doctors, experts, and researchers from time and again have pointed out how kidney disease is often asymptomatic, this is why it is ignored until it becomes advanced. However, at that point the patients could already need dialysis or even an organ transplant. This gap in early diagnosis and treatment is what has made CKD the ninth leading reason of death, worldwide.

When you kidney functions naturally, it works as the powerhouse of filtration. A pair of healthy kidneys are able to filter and process more than 150 liters of fluid from the blood. These organs are also responsible for filtering out the waste and toxins through your urine. Not just that, but your kidneys also help in red blood cells production that keeps you healthy. When all of that does not happen, it can eventually impact every other organ in your body.

Like they say, everything is connected, and it surely is. For instance, somewhere around 20% of the blood that your heart pumps goes to your kidneys. If someone has diabetes and high blood pressure, it could damage the blood vessels and lead to protein in the urine and a slower filtration rate. It can then lead to other chronic infections, autoimmune disorders, and even genetic variants.

Kidney-Body Relation

If you leave your kidney disease untreated, it could lead to kidney failure. This is when you would be more in need of dialysis or a transplant. Doctors have pointed out that most people do not die of chronic kidney disease, rather it impacts their quality of life, worsening their cardiovascular conditions. It can lead to complications like a heart attack, a stroke, or a heart failure.

How Does This Happen?

People who have kidney diseases are at an increased risk for high blood pressure. Due to hurdles in the process of filtration, plaque build ups and hardens the arteries. This in return increases stress on the heart. In fact, the American Heart Association also defined the link between kidney and heart as 'cardiovascular-kidney metabolic syndrome'. This defines a health disorder that is a condition of the overlap of obesity, chronic kidney disease and cardiovascular diseases.

The bleed out of CKD is not just limited to your heart. The National Institute of Health, US points out that along with heart complications and high blood pressure, CKD could also lead to anemia, mineral and bone disorder, metabolic acidosis, malnutrition, and electrolyte imbalances in the blood.

So, What Is The Best Way To Keep Yourself Safe?

The first way is to note any symptoms and get yourself diagnosed. Look for signs like loss of appetite, unexplained nausea or vomiting. Do you feel tired often? Are you having trouble concentrating? Is there any change in how often you go pee?

Other symptoms like a change in your urine color or texture, or feeling itchy or dry, muscle cramps, unexplained weight loss or skin conditions could also signal towards kidney diseases.

However, not always does CKD show symptoms, experts suggest that to be one step ahead, it is important to undergo regular health checkups, including blood culture. General guidelines usually point towards getting a blood test done every 3 to 6 months. For someone with high blood pressure, diabetes or any other disease, the current guidelines say that those people should get regular blood and urine tests to screen for kidney disease. But what really happens is that though these tests exist, they are still used far too little. Doctors point out that many patients skip them because collecting a urine sample feels inconvenient, and overall awareness about kidney disease remains low. As a result, research shows that only about 35 percent of people with diabetes, and just 4 percent of those with high blood pressure, actually end up getting the recommended urine screening.

A ray of hope is that there are now several effective tools to slow the progression of kidney disease. Along with traditional options like ACE inhibitors, newer classes of medications including certain heart failure drugs and GLP-1 drugs. These medicines have shown to help protect kidney function. Although these newer treatments are not widely used yet, their adoption is steadily increasing.

What is important to remember is to also always consult your GP to ensure all preventative measures are followed carefully.
