Sleep Apnoea: Signs You Should Not Ignore, Even If You Sleep All Night

By LeadNG -
  By LEADNG | Health Education Writer Last updated: 14 October 2026 You went to bed early, slept for several hours and woke up expecting to feel refreshed. Instead, you have a headache, your body feels heavy, and you struggle to stay alert during the day. You might blame your workload, the weather, stress or simply not getting enough rest. But what if you are spending enough time in bed and still not getting good-quality sleep? One possible explanation is sleep apnoea , a condition in which breathing repeatedly stops and starts during sleep. Some people with sleep apnoea snore loudly or gasp for air at night. Others mainly notice daytime tiredness, difficulty concentrating or waking up feeling unrefreshed. These symptoms do not automatically mean you have sleep apnoea. However, recognising the pattern can help you know when to seek medical advice. What exactly is sleep apnoea? Sleep apnoea is a sleep-related breathing disorder. The most common type is obstructive sleep aponia, whic...

Students develop cancer technology

By LeadNG -

 A group of OU researchers tucked away inside the Stephenson Research and Technology Center is developing new technologies to detect certain cancers at earlier stages.


“We build toys,” team leader Hong Liu said.

These toys are the equipment that Liu, chair of Biomedical Engineering and his team have developed to make cancer detection a more streamlined and efficient process.

The researcher is focusing on phase-contrast imaging and how it can be used for earlier and less invasive treatment of breast cancer.

Normal X-ray imaging relies on how much radiation objects absorb, according to the OU Biotechnology website. These differences create contrasting images. However, in phase contrast X-ray imaging, the X-ray beams collect information as they pass through the body.

This creates a better picture because it picks up weakly absorbing areas as well and exposes patients to less radiation, according to the website.

The current process to detect breast cancer is slow and painful, research associate Molly Wong said. With this technology, the team hopes to make it a more bearable process.

“Our goal is to be able to provide [patients] a new technology that has a lower dose and allows [doctors] to actually detect the cancer right on the X-ray so [patients] don’t have to go through the not-so fun-process of having a biopsy and waiting,” Wong said.

The team also studies ways to detect leukemia and cervical cancer earlier and easier.

They created a machine called the Automatic Cytogenetic Image Scanning System that helps diagnose diseases such as leukemia much more efficiently, graduate research assistant Yuchen Qiu said.

The typical process of identifying leukemia is a strenuous, manual process, he said. Physicians identify a cell using a low-magnification lens, and then switch to a higher magnification to look for any abnormalities in the cell’s chromosomes.

The process is even harder because the cells clinicians are looking for only account for four percent of all cells, Qiu said.

However, this new machine does all of this work automatically.

This research could one day “help people live longer,” Liu said.

The Science of Satiety: How a High-Protein Diet Accelerates Weight Loss

By LeadNG -
While conducting my own research into health journeys, most people immediately think about restriction—eating less, cutting out favorites, and enduring constant hunger. However, shifting the focus from deprivation to nourishment is often the real secret to long-term success. If there is one dietary change that stands out in nutritional science for managing body composition effectively, it is increasing your daily protein intake. Here is a breakdown of how prioritizing protein transforms your appetite, protects your metabolism, and naturally supports weight loss. 1. The Power of Fullness (Satiety) Hunger is the ultimate enemy of consistency when trying to lose weight. Protein is uniquely powerful because it is the most satiating macronutrient, meaning it keeps you feeling full for longer periods compared to fats or carbohydrates. When you consume protein, it actively suppresses ghrelin (the hunger hormone) while stimulating the release of satiety hormones like peptide YY (PYY) and...

Food as Medicine: How What You Eat Today Can Shape Your Health Tomorrow

By LeadNG -
 Imagine visiting your doctor for a routine check-up. Instead of immediately talking about medication, the conversation begins with a simple question: "What does a typical day of eating look like for you?" A few years ago, that question might have seemed surprising. Today, it's becoming one of the most important questions in healthcare. Researchers are discovering that the food we eat doesn't just satisfy hunger. It influences our heart, brain, immune system, digestive tract, and even our mood. That's why you've probably heard the phrase "Food is medicine." But what does it really mean? Does it mean healthy food can replace medical treatment? Not exactly. It means that the foods we eat every day can either support our long-term health or gradually increase our risk of chronic diseases such as heart disease, type 2 diabetes, obesity, and certain cancers. What Does "Food as Medicine" Really Mean? Think of your body like a house. Ever...

Gut Microbiome 101: Why It Matters More Than You Think

By LeadNG -
  What Is the Gut Microbiome? The gut microbiome is a diverse ecosystem of trillions of microorganisms that primarily live in your large intestine. Think of it as a busy community where beneficial microbes work together to keep your digestive system functioning properly. These microorganisms help: Break down certain foods your body cannot digest on its own. Produce essential vitamins, including vitamin K and some B vitamins. Support the body's natural immune defenses. Help maintain the protective lining of the intestines. Produce compounds that contribute to overall health. A healthy gut microbiome is typically diverse, meaning it contains many different types of beneficial microorganisms that work together in balance. Signs Your Gut May Need More Attention Digestive symptoms don't always mean you have an unhealthy microbiome, but they can be a sign that it's worth discussing with a healthcare professional. Common symptoms include: Frequent bloating Constipation or diarrhea...
