When e-cigarettes first appeared on the market, they were heavily promoted as a safer option for adult smokers trying to quit traditional tobacco. It soon became clear, however, that the nicotine-laden e-liquid used in vaping devices is highly addictive. The full mid- and long-term health effects of vaping are only now beginning to come into focus.
Beyond heart benefits, intense exercise packs an even greater benefit. A recent study shows that just 10–12 minutes of high-intensity activity can slow the growth of colorectal cancer cells. Scientists explored the effects of exercise on colorectal cancer cells. While previous studies have demonstrated that exercise offers protective benefits against cancer, this research sought to deepen our understanding of the underlying molecular processes.
Air pollution can harm the immune system by impairing key defenses against infections. It damages immune cells like macrophages, triggers persistent chronic inflammation, disrupts balanced immune responses, and allows particulates to build up in lung-associated lymph nodes. This ultimately heightens vulnerability to pathogens and related diseases.
Recent research reveals that constipation is linked to a greater risk of heart attacks and strokes, with the danger escalating significantly in individuals who also suffer from high blood pressure. These findings underscore the importance of viewing constipation not merely as a digestive problem, but as a potential cardiovascular risk factor requiring serious attention.
Microplastics have become inescapable. We're ingesting them through food and water, and even inhaling them daily. These tiny fossil-fuel-based particles, smaller than 5 mm, have now been detected deep inside human bones, cartilage, and spinal discs. A recent study reveals that microplastics can penetrate bone tissue, including the marrow, where they may disrupt metabolic processes and harm skeletal health.
New research highlights that Vitamin B3, specifically nicotinamide, may reduce skin cancer risk by up to 54% in individuals with a history of the disease. Dermatologists and skin cancer surgeons frequently recommend nicotinamide to patients, as it helps shield cells from damage associated with UV radiation.
While melanoma and squamous cell carcinoma are generally slow-growing and rare, a new study finds that people with tattoos face a greater risk of developing melanoma. While tattoos raised melanoma risk, they did not increase the odds of squamous cell carcinoma, another sun-driven skin cancer that, unlike the much more lethal melanoma, arises from different skin cells.
New research shows that keeping your heart healthy might depend on what’s happening in your gut. Inside your digestive system live trillions of bacteria, viruses, and fungi, known as the gut microbiome, that influence far more than just digestion. These microscopic inhabitants play a surprisingly powerful role in protecting your heart and reducing the risk of cardiovascular disease.
New research reveals that longer, continuous walks may unlock better heart health and a longer life. Participants who regularly walked for more than 10 minutes at a time showed markedly lower risks of cardiovascular disease and early death compared to those whose walks were short and fragmented.
Healthy aging is defined as the ability to preserve physical, social, mental, and spiritual well-being throughout the aging process. A significant new study now indicates that environmental factors, such as living conditions and lifestyle choices, have a ten times stronger impact and are more influential than genetics in determining healthy aging and longevity.
Regular exercise keeps your body and brain sharp as you age. It preserves mobility, supports independence, and may slow cognitive decline. New research shows exercise reprograms the body at the molecular level, fundamentally transforming biological systems from the inside out.
Do you sleep in total darkness, or is there a glow in your bedroom? New, groundbreaking research shows that eliminating light during sleep may help guard you from heart disease. Researchers gathered the data by following UK Biobank participants’ heart health records for over 9 years by monitoring them with a wrist light sensor.
