I’m a longevity expert – here are 11 ways you can reverse your biological age
Can we really turn back our body’s clock? Dr Raghav Sehgal, a researcher in ageing at Yale University, says that some studies have shown it’s possible to reduce certain aspects of biological age by one to three years through better sleep, diet and exercise. However, he’s sceptical about the more outlandish claims of age reversal, as the testing methods may not take in the full complexity of the damage caused by decades of unhealthy living.

How to future-proof your knees
Our knees are arguably one of our most important joints, but also one of the most poorly looked after. Science tells us putting in some work now pays dividends later.
You might start to notice it as early as your thirties: the dull knee aches when the weather changes, the morning stiffness when you get out of bed. You might think twice about crouching down. They're all unwelcome signs that your knees are not quite the well-oiled joints they once were.
This will be especially true if you hav...
Trump’s Tylenol Directive Could Actually Increase Autism Rates, Researchers Warn

How to spot the symptoms of sepsis and the warning signs in children to know
SUDDEN confusion, racing heart rate, drowsiness, shortness of breath, mottled skin, and fever could be symptoms of sepsis, a life-threatening form of blood poisoning.
Sepsis can arise from acute bacterial infections (such as meningitis), viruses (like covid and seasonal flu), and sometimes infections subtly contracted through a minor cut, graze, or picked spot.

The new weight-loss drugs that shed pounds fast without side effects
Over the last four years, weight-loss drugs that dampen down appetite and promote satiety have revolutionised obesity medicine. They are currently being taken by 1.5 million people in the UK and have already generated billions of dollars in revenue around the world.
But obesity expert Prof Carel Le Roux is particularly excited about the next big drug to hit the skinny-jab market: CagriSema.
Not only did a major new clinical study of the drug show that weight loss would be faster, with overweight and obese participants in the study shedding 23 per cent of their body weight over 68 weeks, but
Snug with your bugs? How microbes control your sleep
Scientists want to use the bacteria living in your gut and mouth to help you sleep better at night.
As you lie in bed tonight, your body will be a teeming mass of activity. Across almost every inch of you – and inside you too – billions of tiny organisms are writhing and jostling for space.

Emerging research suggests that the communities of bacteria, viruses ...

The benefits of early detection when it comes to different cancers

As Professor Patrick Redmond, a GP, associate professor at RCSI, and leading cancer care researcher notes, cancer is now the leading cause of mortality in Ireland, causing 28% of deaths each year: “It’s a big public health issue.
