Kerala is on high alert as chickenpox cases are rising quickly in Kollam district. Over the past week alone, health authorities have confirmed more than 100 new cases, with numbers continuing to climb. This sudden spike has prompted officials to take swift action to prevent further spread. But why is chickenpox, often considered a seasonal illness, circulating now? And what early signs should you watch for to know if you or someone around you might have it?
While chickenpox usually appears more often during the summer months, health officials say unpredictable weather during the rainy season is also playing a role in this surge. Authorities warn that the disease can lead to serious complications in children, teens, older adults, pregnant women, and people with weakened immune systems. Residents are being urged to follow preventive measures and seek medical attention promptly to contain the outbreak.
Chickenpox, caused by the varicella-zoster virus, is extremely contagious and spreads through respiratory droplets or direct contact with someone who is infected. In children, it often starts as a mild rash accompanied by fever, but it can spread quickly in crowded areas.
The virus can also be transmitted through coughing or sneezing, and it is most infectious a day or two before the rash appears and in the early days of the rash. In individuals with weak immunity, the dormant virus may reactivate later in life, causing shingles (herpes zoster).
The varicella-zoster virus spreads very easily through coughs, sneezes, or close contact with an infected person. Kollam’s warm, humid post-monsoon climate creates ideal conditions for the virus to multiply. While the first wave of cases was mostly among children, doctors now warn that adults are also increasingly vulnerable, according to The New Indian Express.
Spotting chickenpox early means looking for general warning signs like fever, fatigue, headache, and loss of appetite, which usually appear one to two days before the rash. The rash itself starts as tiny red spots that later form fluid-filled blisters and eventually scab over. Paying attention to these early symptoms—especially after known exposure—can help identify the infection sooner.
The first rash usually shows up as small red bumps on the face, chest, or back. These bumps quickly turn into blisters filled with fluid, which are contagious. Over a few days, the blisters break and crust over, forming scabs. It’s common to see spots, blisters, and scabs all at the same time, according to the CDC.
The Mayo Clinic explains that chickenpox progresses in three main stages:
According to the Cleveland Clinic, complications are uncommon but can include pneumonia, brain inflammation (encephalitis), and bacterial skin infections. Vulnerable groups, such as infants, pregnant women, older adults, and people with weakened immunity are at higher risk of severe illness.

What's worse than running nose, continuous sneezing, and a fever? It is the dreams you get when you have finally managed to put yourself to sleep, and those dreams are bad, scary, intense, and negative. Why does this happen?
A dream is basically a series of thoughts, images, sensations that you feel while you are sleeping, and scientists tell us that we have our strongest dreams during the rapid eye movement or the REM of the sleep stage.
Certain factors, including you health could influence your sleep visions and your dreams. A change in body temperature, especially when it is higher than usual could lead to a fever dream, which mostly could be intense, like a nightmare.
As per a 2016 study published in the International Journal of Dream Research, 94 per cent of participants described their fever dreams as negative. Another 2013 study noted that one of the participants had dreams that would move "back and forth between a very difficult circumstance and a very comfortable circumstance." A recent online study in 2020, published in the journal Frontiers Psychology noted that of the 164 participants, 100 of them reported fever dreams. Most of them said that fever dreams were more bizarre, and negatively toned.
While fever dream is known in the medical literature, the scientific studies on the same are limited. Many often describe this as an emotionally intense, troubling, strange, out of character, or a scary dream. The dreams could be the result of less social interactions due to someone being sick.
A fever dream happens when the normal body temperature rises 2 degrees above. The normal body temperature is between 97 and 99 degree F. Anyone can develop a fever, due to the following conditions:
While there is no exact reasoning for it, the 2020 online study notes that the concept behind this is the 'over-heated' brain. High temperature of the body could disrupt the brain's normal cognitive functions. The authors of the 2020 study note, "The basic idea is that the ‘over-heated’ brain is not functioning properly and, therefore, dreams are more bizarre.”
During the REM stage of sleep, the phase where your most vivid dreams unfold, the body already struggles to regulate its internal temperature. When a fever strikes, it disrupts this delicate balance even further, often resulting in intense or disturbing dreams. Fevers can also stir the mind in other unsettling ways, sometimes causing waking hallucinations, irritability, or even brief episodes of confusion.
Dr Mark Rosenblum, who is a sleep psychologist with Hennepin Healthcare, tells CBS News that the reason behind intense dream during sickness is due to REM. He says, "If someone's not getting enough sleep, they get what's called REM rebound on the following nights. And when we have REM rebound, what we'll find is all our dreams tend to be very intense."
As per a 2016 study published in the International Journal of Dream, fever dreams contain some sort of spatial distortion, that include:

Bengaluru based neurosurgeon Dr Arun L Naik dropped a video on his Instagram account @doclogues, which has shocked the world, because he says that 'Dementia Starts in Your Legs'.
As of now, most of us knew that it is a general term for a loss of thinking, and is part of normal aging and related to brain diseases that damage the nerve cell. However, Dr Naik notes that as per a 2020 study, it was found that those who walk in a slow speed, especially older adults, were more likely to face the risk of cognitive decline. "Why?" To this, Dr Naik writes that walking is not just a physical task, "it is a full brain workout".
Dr Naik writes that there exists a brain-leg connection. "Every step involves coordination between the frontal lobe, cerebellum, spinal cord, and proprioceptive feedback loops."
The second point he notes is of the circulation boost. He writes that leg movement improves blood flow to the brain, and it delivers oxygen, glucose, and clears out toxins.
Then comes gait changes, which the doctor says must be considered as brain warning. It is brain's way to tell that changes in walking style, balance, or pace could proceed to memory symptoms by years.
Lastly, he notes is the neuroplasticity in motion. He says that walking stimulates the brain-derived neurotrophic factor, which strengthens neuron connections. This is why, "weak legs can speed up cognitive decline," he says in his video.
The study is a 2020 review, which was published in the Journal of Aging Research. This is where it was seen that older adults, who stay physically active are less likely to develop cognitive decline or dementia. The study analyzed over 1,60,000 people and found that regular exercise reduced the risk of dementia by 28 per cent and Alzheimer's disease by 45 per cent.
With aging, especially from mid-50s, most adults begin to lose 1 to 2 per cent of muscle mass every year, this process is further accelerated by inactivity. This loss then not only affects mobility, but also metabolism and blood circulation, which results in less oxygen reaching to your brain, as the doctor also explained.
This is why the doctor says, "if your legs slow down, your brain may follow".
The answer is yes. Dr Naik also says, "studies have shown that it is never too late to start. Starting even in your 60s can reduce dementia risk by a mile". So, what is he asking people to start? He is urging people to start some activity, to help their bodies move, and enable the brain to leg coordination.
The doctor also notes some "strategies" to prevent dementia in the caption of his post through movements, which are as followed:

If you are someone who cracks your knuckles every day just for that oddly satisfying pop, you are not alone. For many, the sharp sound brings a fleeting sense of relief or relaxation. Yet, there has long been a debate about whether this seemingly harmless habit could actually damage your joints or raise the risk of arthritis.
For those unversed, the pop you hear when cracking your knuckles comes from gas bubbles in the joint fluid collapsing. For most people, it’s harmless, though it can occasionally cause slight swelling or a temporary drop in grip strength. The long-standing belief that it leads to arthritis is not backed by science, but using too much force could result in minor injuries, like ligament sprains or dislocations
Addressing this common worry, orthopedic surgeon Dr. Manan Vora answered the question in a viral reel that has now surpassed 2.5 million views. A viewer asked him, “Can cracking knuckles every day lead to arthritis?”
Dr. Vora said, “The pop you hear when cracking a knuckle is the sound of these bubbles bursting within the synovial fluid inside the joint,” he clarified.
Knuckle cracking is a habit many pick up early in life, often because they enjoy the sound or the temporary feeling of looseness in the fingers. According to the Johns Hopkins Arthritis Center, the sound comes from changes inside the joint capsule, which is filled with synovial fluid. This fluid not only lubricates the joints but also nourishes the surrounding bones.
“A variety of gases are dissolved in this fluid. When a knuckle is cracked, stretching the capsule lowers the pressure inside, creating a vacuum. The dissolved gases form a bubble, which bursts, producing the familiar popping sound. It takes time for the gases to re-dissolve, which is why you can’t immediately crack the same knuckle again,” Johns Hopkins adds.
Many worry that frequent knuckle cracking could trigger arthritis. However, research shows there is no evidence linking the habit to arthritis or long-term joint damage. A few reports have noted that excessive cracking may occasionally cause minor ligament strains or tendon dislocations, but these injuries typically heal on their own.
Some studies also suggest that habitual knuckle crackers might have slightly reduced grip strength over time, but this does not equate to arthritis. Rarely, “knuckle pads” can develop in young people who crack their knuckles often, but these are mostly cosmetic.
Several studies back up the conclusion that knuckle cracking does not cause arthritis. For example, a study by the Uniformed Services University of the Health Sciences followed 215 participants, 20% of whom regularly cracked their knuckles. They found arthritis in 18.1% of knuckle crackers and 21.5% of non-crackers, essentially the same rate, showing no link between the habit and the disease.
A famous anecdote comes from Dr. Donald Unger, who cracked the knuckles on his left hand twice daily for 50 years while leaving his right hand untouched. Published in Arthritis and Rheumatism in 1998, the informal experiment revealed that neither hand showed signs of arthritis. More recent studies in 2017 reached similar results, finding no difference in hand function between people who cracked their knuckles and those who didn’t.
Arthritis is a condition that causes inflammation and pain in one or more joints, often leading to stiffness and limiting the joint’s range of motion. Genetics play a major role, with environmental triggers contributing to inflammatory types, and age or mechanical stress driving degenerative arthritis.
Other risk factors include obesity, previous joint injuries, family history, older age, and being female. But as research confirms, knuckle cracking is not one of them.
