When we experience stress, panic, or anxiety, the sympathetic nervous system—responsible for the “fight or flight” response—is activated. This increases heart rate, raises blood pressure, and accelerates breathing, preparing the body to respond to danger. While this reaction is useful in real emergencies, chronic or frequent activation can lead to feelings of tension, overwhelm, or mental

In a historic medical achievement, surgeons at the National Institute of Cardiovascular Diseases (NICVD) successfully performed Pakistan’s first-ever total arch replacement using the frozen elephant trunk (Tarfet) technique on a 16-year-old boy from Khairpur. The 16-hour-long surgery, recognized as one of the most technically complex procedures in cardiovascular medicine, marks a major milestone

When it comes to choosing a healthy snack, pistachios and peanuts both shine, but in slightly different ways. Nuts are universally recognized for their health benefits, providing heart-healthy fats, plant protein, fiber, and antioxidants. A daily handful—about 30 grams or a quarter cup—has been linked to improved weight management, lower risk of type 2 diabetes and heart disease, and even brain

In a historic medical breakthrough, scientists have successfully restored hearing in individuals born deaf by repairing a single faulty gene through viral gene therapy. This revolutionary treatment marks the first time that patients who had never experienced sound are now able to perceive speech, music, and everyday noises, offering hope to millions affected by hereditary hearing loss worldwide.

Experts emphasize that one of the earliest and often overlooked signs of vitamin D deficiency is persistent lower back pain or stiffness. This symptom arises because vitamin D is essential for maintaining strong bones and healthy muscles. When levels of the vitamin drop, the body may begin to experience subtle aches and discomfort that can gradually intensify over time. Many people may not

Researchers at North Carolina State University have discovered that cockroach infestations can significantly degrade indoor air quality by releasing high levels of allergens and bacterial endotoxins. The study, conducted in multiple apartment complexes across Raleigh, found that female cockroaches produce nearly twice as many endotoxins as males due to higher food consumption. These endotoxins,

Scientists at the University of Nottingham have developed a groundbreaking gel capable of repairing and regrowing tooth enamel, offering the possibility for teeth to heal themselves for the first time. This innovative bioinspired gel represents a major advance in dental science, moving beyond traditional treatments that only slow down tooth decay.

A paralyzed man in Japan has regained the ability to stand and is now relearning how to walk after receiving a pioneering stem cell treatment for spinal cord injuries. The procedure, developed by researchers at Keio University in Tokyo, marks a major breakthrough in regenerative medicine. It involved the use of neural stem cells derived from induced pluripotent stem cells (iPS cells), which can

A recent scientific study has revealed a promising connection between vitamin D and the biological aging process, suggesting that this essential nutrient may help slow down how quickly the body ages at the cellular level.

Recent neuroscience research indicates that excessive use of short-form video apps such as TikTok may negatively affect attention span and cognitive performance. The brain adapts to constant scrolling and rapid content exposure by seeking instant gratification, which can weaken its ability to stay focused on complex or time-consuming tasks.
