Strengthening your bones is not something that can happen overnight, it takes years for your body to build strong bones and even then, it is natural for them to lose their dexterity. All you can do is keep your body healthy to make sure it is prepared for any unexpected situations. For years, many older adults have been told to take vitamin D and calcium supplements to keep their bones strong and prevent falls. However, a new report from U.S. Preventive Services Task Force (USPSTF) is changing that advice. This report suggests that for most older people, these supplements don't actually prevent falls or broken bones. This might be surprising news, we must understand why falls happen more often as we age, what vitamin D and calcium do in the body, and most importantly, what you can do to stay safe and prevent fractures.

What the Report Says

According to the report, vitamin D supplements don't seem to help prevent falls or broken bones for most people over 60. They also found that these supplements, especially with calcium, might increase the risk of kidney stones. This report doesn't mean people with weak bones (osteoporosis), low vitamin D, or who take vitamin D for other health reasons shouldn't take it. It just means that for most healthy older people, these supplements don't prevent falls and fractures.

Why Older People Fall and Break Bones More Easily

There are many reasons why older people are more prone to breaking their bones. Our bones are strongest when we're in our 20s and 30s, and they get weaker as we age so naturally, they can break easily. It can also be harder to move around as we get older, sometimes because of problems like arthritis this can affect how we walk and make us less steady.

There are also different issues like neuropathy, which is a nerve problem that can also make it harder to feel your feet and keep your balance. Eyesight is also a culprit as it can cause you to feel dizzy and fall. Some medicines can also make people feel unsteady, and older people often take more medicines than younger people. Low vitamin D itself can also increase the risk of falls, so keeping vitamin D levels up is still important.

Better Ways To Protect Your Bone Health

USPSTF recommends a few better ways to protect your bone health and prevent broken bones and falls.

Walk Regularly

Regular walks strengthen your muscles and bones, which helps you stay steady on your feet. It is as simple as practice makes perfect so the more you walk, the better it is. Walking also improves your balance, making you less likely to fall.

Do Strength Training

Strength training, like lifting weights or using resistance bands, makes your bones stronger and helps prevent fractures if you do fall. It is like a safety cushion, but you must be careful while doing so because it can lead to injuries if done too much.

Practice Balance

Activities like tai chi, Pilates, and yoga can improve your balance and coordination, making you more stable and less prone to falls. These can also help you improve your muscle flexibility and strength that in turn helps your body be stronger.

Check Your Medicines

If you have osteoporosis, talk to your doctor about medications that can help strengthen your bones and lower your risk of fractures. Many medications can also have unsavory side effects like weakened joints, losing muscle strength, etc.

Eat Enough Protein

A proper diet goes a long way when it comes to your entire body health. So to keep up with your body’s nutrition and muscle health, eat more protein along with a balanced meal that includes loads of fiber, healthy fats and carbs.

Get Your Eyes Checked

Having poor eyesight can be difficult, not only does it make life difficult without glasses, but it also increases the possibilities of getting into minor accidents like bumping into people and missing objects placed in front of us.

Get Enough Sleep

Getting enough sleep is also important because when you are not sleeping, you get disoriented and can ignore even obvious things like the last stair in the staircase. Make sure you get enough sleep to keep you fresh and focused.

Make Your Home Safe

There are many things that can cause you to have accidents, even in your home. To avoid such falls, make sure there are no lose ends like crooked floor panels, rugs that are sticking out or protruding furniture that can hurt your knees

Bird flu viruses pose a particular danger to people because they can continue multiplying even at temperatures that would normally stop most infections. Fever is one of the body’s natural ways to slow viruses, yet new research from the universities of Cambridge and Glasgow shows that avian strains can survive what should be a hostile environment.

The study, published in Science, identifies a key gene that influences how well a virus copes with heat. This same gene moved into human flu strains during the 1957 and 1968 pandemics, allowing those viruses to spread more easily.

How Flu Viruses Thrive In The Body

Human influenza viruses infect millions each year. The seasonal strains we see most often fall under influenza A and tend to do well in the cooler temperatures of the upper respiratory tract, which is close to 33°C. They are less suited to the warmer, deeper parts of the lungs, where temperatures reach about 37°C.

As per Science Daily, when the body cannot slow an infection, the virus continues to multiply and spread, which can lead to more serious illness. Fever acts as a protective response, pushing body temperature as high as 41°C. Until now, the exact reason why fever slows some viruses but not others has been unclear.

Avian influenza behaves differently. These viruses usually grow in the lower respiratory tract, and in their natural hosts, such as ducks or seagulls, they often infect the gut. Temperatures in these areas can reach 40°C to 42°C, which helps explain their greater tolerance to heat.

How Fever Limits Infection and Why Bird Flu Can Resist It

If left unchecked, a virus can move through the body and cause significant harm. Fever is one of the body’s most familiar defence responses and can raise the core temperature to levels that inhibit many pathogens. Scientists have long known that some viruses withstand these temperatures, but the reason behind this resistance has remained uncertain.

Avian flu strains show a clear advantage in hotter environments. They thrive in the lower airways and, in birds, survive in the high heat of the gut. These features distinguish them from human influenza strains, which prefer cooler tissue.

Earlier studies in cell cultures hinted that avian flu copes better with fever-range temperatures than human strains. The new research offers direct evidence from animal experiments, helping explain why fever is effective against some types of influenza but far less useful against others.

Experiments Show Why Fever Slows Human Flu but Not Avian Flu

Researchers from Cambridge and Glasgow recreated fever-like conditions in mice to examine how different viruses responded. They worked with a lab-adapted human influenza strain known as PR8, which does not pose a threat to people.

Mice do not typically develop a fever from influenza A, so the scientists raised the temperature of the environment to lift the animals’ body temperature.

The findings were striking. When body temperature rose to fever levels, the human-origin virus struggled to replicate, and the infection weakened. Avian influenza behaved very differently. Raising the temperature did not stop the virus from multiplying, and a small increase of only 2°C was enough to turn a normally severe human-origin infection into a mild one.

The PB1 Gene Helps Bird Flu Withstand Fever

The study also identified the PB1 gene as a major reason why bird flu can tolerate heat. PB1 helps the virus copy its genetic material inside infected cells. When viruses carried an avian-type PB1 gene, they were able to endure high temperatures and still cause severe disease in mice. This matters because avian and human flu viruses can exchange genes when they infect the same host, such as pigs.

Dr. Matt Turnbull, the study’s first author from the Medical Research Council Centre for Virus Research at the University of Glasgow, explained that this gene swapping remains a major concern for emerging influenza strains. He noted that similar exchanges occurred in 1957 and 1968, when human flu viruses replaced their PB1 gene with one from an avian strain. According to the researchers, this may help explain why those pandemics were so severe.

In moments where life seems to slip away, many people describe seeing a bright tunnel with a strong light shining at the end. The image feels almost otherworldly. Whether it happens during major surgeries, car crashes, or sudden accidents, people from different places and backgrounds share accounts that sound strikingly alike. Films, novels, and personal stories often mention this same vision during a near-death experience. While some link it to a glimpse of the afterlife, there may be a scientific explanation for why the mind creates this scene.

Is it a sign of something beyond the physical world, a reaction of the mind in distress, or part of how the brain behaves as it shuts down? Here is what researchers have learnt.

Do You Really See A Tunnel Of Light When You Die?

Yes. Scientists agree that many people do report seeing a tunnel of light when death is close. Even though death is certain, much about it still feels unclear. For generations, people have tried to understand what takes place in those last moments. Only in recent years, as medical care has advanced, have researchers been able to look more closely at near-death experiences, also known as NDEs, which occur when someone comes dangerously close to dying.

One of the most repeated features of NDEs is the bright tunnel, a sight described by millions. It is not a quick trick of the mind. People often speak of it as deeply emotional and unforgettable. This leads to difficult questions. Does this vision suggest something beyond physical life, or is the brain responding to extreme stress in its final effort to survive?

Why Do You See A Tunnel Of Light During Near-Death Experiences?

When someone nears death, the body begins to change very quickly. Vital functions start to drop. The heart may slow, reducing the amount of oxygen that reaches the brain. Body temperature can fall, and breathing may become weak or uneven. Along with these physical changes, the brain also reacts in its own way.

Tunnel Of Light During Death Experiences: What Scientists Found

A team at the University of Michigan studied what happens in the brain as a person dies. They examined four people who were removed from life support and found that two of them showed a strong surge of brain activity right before death.

The pattern of activity was similar to what occurs when a person is awake and using higher thought. These bursts were produced by gamma waves, which are linked to conscious processing. In one patient, the rise in gamma activity was nearly three hundred times higher than normal.

Jimo Borjigin of the University of Michigan suggested that this might show a form of hidden awareness that becomes active just before death.

Professor Borjigin explained that some people near death may recall seeing or hearing things or may feel as though they are watching their body from above, or even moving through space. She said her team may have identified the basic brain steps connected to this type of hidden consciousness.

She added that future research needs to involve people who survive such events, so their brain activity can be compared with their own descriptions of what they experienced.

Another study in the Journal of the Missouri State Medical Association also explores how consciousness may shape near-death experiences. The researchers note that there is still much to learn about how the brain creates awareness and how that awareness influences what people see or feel as they approach death.

2025 was the year of viral health claims. These claims had shock-value, but often were half-baked theories, which spread faster than facts. At Health and Me, we made it a mission to burst health myths, and help our readers make better and healthier life choices. Here is a recap of the myths we debunked this year.

Myth 1: The Pink Salt Trick - Is It A Shortcut To Weight Loss?

The pink salt, lemon and water drink went viral on TikTok as a “metabolic reset.” Its simplicity made it tempting, but there is no scientific evidence that it burns fat or suppresses appetite.

What expert explained

Nutritionists warn that excess sodium can raise blood pressure and cause bloating. Pink salt also lacks iodine, making daily consumption risky for thyroid health. Investigations and dietitians have repeatedly confirmed that this drink does not boost metabolism or detox the body. The trend particularly targeted women seeking quick fixes, but experts remind that weight loss still relies on balanced eating and consistent movement.

Myth 2: Painkillers Are Neurotoxins That Can Cause Infertility

A June 2 viral reel claimed that common painkillers raise heart risks by 20 percent, cause fertility problems, harm mental health, and act as “neurotoxins that kill the nervous system.” The influencer added that taking ibuprofen during periods “cuts off communication between the uterus and brain.”

What the science actually says

Experts clarified that painkillers are not neurotoxins and do not interfere with the nervous system. They work by inhibiting enzymes responsible for producing pain-related chemicals. No part of this process kills nerves or blocks communication between organs and the brain.

On fertility, reproductive specialists at Instituto Bernabeu and findings from a 2016 prospective cohort study confirmed that standard painkillers like paracetamol, ibuprofen, aspirin, and acetaminophen do not reduce fertility or affect the ability to conceive. In fact, ibuprofen is often used to ease severe menstrual cramps caused by underlying conditions such as endometriosis, which itself may influence fertility.

Myth 3: Producing Semen Automatically Means High Fertility In Men

We also tackled a long-standing myth many couples quietly worry about. A large number of men believe that producing semen automatically means they have healthy sperm.

What expert explained

Senior IVF specialist Dr Beena Muktesh reminded us that fertility is not about semen production but sperm quality. Sperm count, movement, and shape determine whether conception is possible. Even semen that appears normal in volume or texture can contain poor-quality sperm or show signs of infection or inflammation.

A simple semen analysis can reveal key issues. Low count, weak motility, abnormal shape, and pH imbalance can all affect fertility despite regular ejaculation. The takeaway is clear: semen production alone is never a measure of reproductive health.

Myth 4: Aluminum In Vaccines Cause Food Allergies

Health Secretary Robert F Kennedy Jr. claimed that aluminum in vaccines triggers food allergies, echoing a belief that resurfaced across social media.

What global health bodies say

Aluminum is an adjuvant that strengthens immune response and has been safely used for decades. It is found in vaccines that protect against diphtheria, tetanus, HPV, hepatitis, pertussis, and more.

While a 2022 study explored a possible link between aluminum exposure and asthma, it also stressed the need for more research. A large study from Denmark in 2023 found no such link, and the American Academy of Pediatrics clearly stated that aluminum in vaccines does not cause food allergies. Genetics and delayed.

Myth 5: ADHD Ca Be Cured Through Diet Alone

One popular reel claimed that the “actual treatment” for ADHD lies entirely in food and nutrition. While diet does influence brain health, experts highlight that ADHD cannot be cured solely through food.

What expert says

Neurologists acknowledge the role of nutrition in managing symptoms, especially through gut health and nutrients such as fibers, inulin and antioxidants. Some studies show that zinc, iron or certain dietary changes may reduce symptom severity. However, all research agrees that diet cannot cure the condition. ADHD requires a combination of therapy, behavioral strategies and, when needed, medication.
