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

The NHS has released an alert for people taking a widely prescribed medication used by millions across the UK. Diabetes rates are at an all-time high, with the latest data showing more than 5.8 million people currently living with the condition.

Diabetes UK estimates that around 4.6 million people have already been diagnosed. At the same time, close to 1.3 million people are believed to have Type 2 diabetes without knowing it. The number of cases continues to climb, with figures from 2023–24 showing an increase of 185,034 compared to the previous year.

What Is Metformin Used For?

Metformin is most commonly prescribed for people with Type 2 diabetes. It helps lower and stabilise blood sugar levels and is often the first medicine recommended, alongside changes to diet and physical activity. According to Healthline, it is not used to treat Type 1 diabetes.

What Is Diabetes?

Diabetes is a condition where blood sugar levels become too high. There are three main types. Type 1 diabetes cannot be prevented and is usually diagnosed in childhood. Type 2 diabetes can sometimes be prevented or managed through lifestyle changes such as healthier eating, regular exercise, and weight loss. Gestational diabetes develops during pregnancy. People with Type 1 diabetes need insulin for life, while many with Type 2 or gestational diabetes may manage their condition through lifestyle changes and, in some cases, medication.

Metformin Warning: NHS Issues Alert

The NHS says that people taking metformin should be aware of certain symptoms. Information published on the NHS website lists six common side effects of the medicine. These include:

• feeling sick
• being sick
• diarrhoea
• stomach pain
• loss of appetite
• a metallic taste in the mouth

The NHS also notes that metformin can increase the risk of vitamin B12 deficiency. Some people may experience low blood sugar, but this usually happens only when metformin is taken alongside other diabetes medicines such as insulin or gliclazide.

However, the NHS warns that there are other, more serious side effects. In two situations, patients are advised to contact their GP “straight away,” while one requires calling 999 “now.”

Metformin Serious Side Effects

According to the NHS, serious side effects are uncommon and affect fewer than 1 in 10,000 people. However, medical help should be sought immediately by calling a doctor or dialling 111 if:

you feel generally unwell with extreme tiredness, fast or shallow breathing, feeling cold, and a slow heartbeat

the whites of your eyes turn yellow, or your skin becomes yellow, which may be harder to notice on brown or black skin, as this can indicate liver problems

Metformin Serious Allergic Reaction

In rare cases, metformin can cause a severe allergic reaction known as anaphylaxis. The NHS advises calling 999 immediately if:

• your lips, mouth, throat, or tongue suddenly swell
• you are breathing very quickly or struggling to breathe, including wheezing or feeling as though you are choking
• your throat feels tight or you have difficulty swallowing
• your skin, tongue, or lips turn blue, grey, or pale, which may be easier to spot on the palms or soles in people with darker skin
• you suddenly feel confused, very drowsy, or dizzy
• someone collapses and cannot be woken
• a child becomes limp, floppy, or unusually unresponsive, with difficulty holding up their head or focusing

The NHS adds that you or the affected person may also develop a rash that is swollen, raised, itchy, blistered, or peeling. These signs point to a serious allergic reaction and may require urgent hospital treatment.

The public is being advised to limit close contact with others if they experience flu or Covid symptoms, as the NHS braces for a challenging winter ahead. A mutated, or “drifted”, version of the H3N2 flu strain is fuelling a faster and earlier rise in infections and hospital admissions in 2025. Dr Conall Watson, Consultant Epidemiologist at the UK Health Security Agency, has urged those who are eligible to get vaccinated at the earliest.

He said there are also everyday precautions that can help protect others, especially during the festive season. “If you have symptoms of flu or Covid-19, such as a high temperature, cough, or feeling tired or achy, you should try to reduce contact with other people, particularly those who are more vulnerable. Regular handwashing and good ventilation indoors both make a difference. If you need to go out while unwell, wearing a face covering is worth considering,” he added.

This guidance becomes even more important in the run-up to Christmas, when families tend to gather and older relatives, who face a higher risk of serious illness, are often present.

Flu Symptoms 2025: Less Obvious Symptoms People Often Miss

While many flu symptoms are widely recognised, some are less commonly associated with the illness. The NHS lists ten typical flu symptoms, which often appear suddenly.

Among these, three signs that people may overlook are trouble sleeping, a reduced appetite, and feeling unusually tired or drained. During the busy weeks leading up to Christmas, these symptoms can easily be dismissed as stress or exhaustion rather than flu.

The remaining seven symptoms listed by the NHS include a sudden high temperature, body aches, a dry cough, sore throat, headache, diarrhoea or stomach pain, and feeling sick or being sick.

At the same time, the NHS is dealing with added pressure from a surge in winter viruses alongside a five-day strike by resident doctors, previously known as junior doctors. Health leaders and the Government have called on doctors to withdraw the strike, which ministers have described as reckless and irresponsible given the strain on services.

Flu Symptoms 2025: NHS Under Pressure as Winter Challenges Mount

Home Secretary Shabana Mahmood, as per The Independent, said that strikes within the NHS “undoubtedly” put lives at risk. Speaking to Sky News’ Sunday Morning With Trevor Phillips, she said, “We want to ensure the NHS is supported through a difficult winter and this flu outbreak we are currently seeing. It is important that everyone understands what is at stake.”

She also pointed to a difference between the position taken by resident doctors’ leadership and the views of individual doctors, noting that the situation remains sensitive as the NHS navigates one of its most demanding winter periods.

Flu Symptoms 2025: Who Can Still Get Vaccinated?

The NHS provides the flu vaccine free of charge to groups considered most at risk of serious illness. This includes people aged 65 and above, those with certain long-term health conditions, and pregnant women, as per the official NHS website.

The offer also extends to care home residents, carers who look after older or disabled individuals or receive a carer’s allowance, and people living with someone who has a weakened immune system. Frontline health and social care workers are also eligible and can usually receive the vaccine through their employer.

Children are included too. A nasal spray version of the flu vaccine is offered to children aged two and three, as well as school-going children from reception through to year 11.

This is because children tend to catch and spread flu more easily. Vaccinating them not only protects their own health but also helps reduce the risk for vulnerable people around them who could become seriously ill.

Delhi residents continue to struggle with deteriorating air quality, which is taking a visible toll on overall health. The Air Quality Index (AQI) across Delhi NCR crossed 400 on December 15, 2025, placing it firmly in the ‘hazardous’ category. With breathing outdoor air becoming increasingly difficult, many people are turning to air purifiers for relief, both at home and in offices. Yet a common concern persists. Are air purifiers truly safe, or do they come with hidden drawbacks? And can excessive use cause problems of its own? We got in touch with Dr Aditya Nag, Assistant Professor, Department of Respiratory Medicine, NIIMS Medical College and Hospital, to know more about the same.

What Is An Air Purifier?

An air purifier, often referred to as an air filtration system, is designed to clean indoor air by filtering out harmful particles and pollutants. It works by pulling in air from the room, passing it through layers of filters, and releasing cleaner air back into the space. These devices are widely used in homes and offices to create a healthier and more breathable environment.

Dr Aditya Nag said, “Air purifiers are particularly helpful in removing dust, pollen, pet hair, mould spores, and other microscopic particles that can trigger allergies or worsen respiratory conditions. Their internal filters trap these pollutants, helping improve indoor air quality. In simple terms, they aim to make the air inside cleaner, safer, and easier to breathe.”

Are Air Purifiers Safe To Use?

Air purifiers rely on fans to draw air through one or more filters that capture pollutants before circulating cleaner air back into the room. They come in many forms, from portable units that can be shifted between rooms to wall-mounted models. There are also compact desktop versions and even wearable purifiers available today.

According to our health expert, air purifiers are generally safe and effective at improving indoor air quality, provided the right type is chosen and maintained properly. Models that use True HEPA filters and do not produce ozone are considered the safest. However, ozone-generating purifiers, certain UV-C devices without adequate shielding, and units with poorly maintained filters can release harmful by-products. These secondary pollutants may irritate the lungs and airways. This is why it is important to check safety certifications, replace filters on time, and avoid technologies known to emit ozone.

Overusing Air Purifiers Is Bad For Lungs?

Our expert points out that running an air purifier nonstop on high settings in tightly sealed rooms can reduce indoor humidity levels significantly. This drop in moisture can be uncomfortable for the respiratory system. “While clean air is important, the lungs function best when the air also has enough moisture,” he explains.

Very dry indoor air can irritate the nose, throat, and airways, leading to symptoms such as dryness, scratchy throat, persistent dry cough, burning eyes, and even frequent nosebleeds, especially in the morning.

Dr Nag stresses that air purifiers remain extremely useful, particularly for children, older adults, and people with asthma or allergies. The key is balanced use. He advises switching to auto mode instead of running turbo mode all the time, avoiding completely sealed rooms, and maintaining indoor humidity between 40 and 60 percent. This can be done with a humidifier or simple home measures.

Is It Safe to Sleep Near an Air Purifier?

Many people place air purifiers in their bedrooms, often close to the bed, which raises questions about safety during sleep. According to our expert, sleeping near an air purifier is generally safe and can even be beneficial, as long as basic precautions are followed.

Most modern air purifiers, especially those equipped with HEPA filters, are built for continuous use and operate quietly enough for bedrooms. By reducing allergens and airborne particles overnight, they may help improve sleep quality, particularly for people with allergies or breathing issues.

What To Look For In An Air Purifier?

When choosing an air purifier, it is important to look for models with True HEPA (H13 or H14) filters and activated carbon layers for effective removal of particles and odours. Check whether the purifier is suitable for your room size by reviewing its CADR, or Clean Air Delivery Rate. Noise levels are another key factor, especially if the device will be used in a bedroom.

It is also wise to consider the cost and frequency of filter replacement. Be cautious of purifiers that rely on ozone-producing ionisers or certain UV features. A reliable air purifier should offer multi-stage filtration, cover the intended space efficiently, and operate quietly without compromising safety.
