Many people believe the stereotype that getting chilled or spending time in frosty air causes the common cold—but that’s actually a myth. According to medical experts, viruses—not cold temperature—are the true culprits behind respiratory illnesses like colds and the flu. Studies highlight that most colds are caused by over 200 different viruses, such as rhinovirus….
The human gastrointestinal system is often seen as a simple food processor—but recent science reveals it has its own complex nervous system, earning it the nickname the “second brain.” Research shows that your gut contains around 100 million neurons embedded in the walls of the digestive tract, capable of functioning independently of the central nervous…
Intermittent fasting (IF) has gained serious popularity as a go-to health strategy—but with that rise comes confusion. One persistent myth claims that fasting for 16–20 hours daily automatically leads to massive fat loss and superior metabolism. However, research from reviewed sources indicates the reality is more nuanced. For instance, medical experts emphasise that IF’s effectiveness…
Each time you take a breath, your lungs engage in much more than exchanging oxygen and carbon dioxide. Deep inside the alveoli (those tiny sacs where gas exchange happens), a sophisticated immune defense quietly works. Specialized cells called alveolar macrophages patrol the lung surface, capturing dust, microbes, and harmful particles before they can trigger inflammation….
The human body is home to a vast and diverse community of microorganisms, collectively known as the microbiome. This ecosystem comprises trillions of bacteria, fungi, viruses, and other microbes that inhabit various parts of the body, including the gut, skin, mouth, and respiratory tract. Remarkably, the number of microbial cells in the human body may…
In today’s world, health information is abundant, but not all of it is accurate. Many widely believed health myths have been debunked by scientific research, yet they persist in public consciousness. Understanding the facts is crucial for making informed health decisions. Myth 1: Cracking Knuckles Causes Arthritis A common belief is that cracking your knuckles…
Recent research indicates microplastics—tiny plastic particles found in food, water and even the air—may disrupt the gut microbiome in ways that could affect human health. Though still emerging, several controlled studies in model organisms show that ingestion of microplastic particles can alter gut microbial composition, reduce beneficial bacteria, and increase inflammation markers. These experiments demonstrate…
For decades, the belief that cracking your knuckles leads to arthritis has echoed through households and doctor’s offices. The popping sound may annoy others, but does it really pose a health risk? According to orthopedic specialists and several peer-reviewed studies, this common habit is not linked to arthritis. The sound produced comes from the rapid…
The idea that everyone must drink exactly eight glasses of water a day is one of the most persistent health myths. While hydration is crucial, the “8×8 rule” (eight 8-ounce glasses) isn’t based on scientific evidence. The truth is, water needs vary from person to person depending on factors like climate, activity level, diet, and…
Many people grow up hearing that cracking knuckles will eventually lead to arthritis. This belief has been passed down for generations, often used as a warning to stop the habit. While the sound may be unpleasant to some, the truth behind this claim is quite different from the myth. Medical studies have explored this connection,…
