Older fishermen who dive for their work show a mix of health traits that scientists want to understand. Researchers first looked at how the blood vessels, body shape, and everyday habits of these men differ from younger people. They also measured how strong the fishermen’s arms and legs were d
Recent science shows that a simple gas—hydrogen—is more than just a building block of water. Because it is so small, the molecule can slip through cell walls and even the blood‑brain barrier, reaching places that many medicines cannot. Researchers have tested hydrogen in a variety of ways: breathing
The way the weather feels can change how our hearts work. When it is too hot or too cold, people are more likely to have heart attacks, strokes, sudden death and other serious problems. Scientists say the problem is getting worse because global temperatures are rising and extreme weather events ar
Research suggests that adding just a few extra minutes of walking and sleep each day might lower heart disease risk, even if the evidence isn’t rock solid. Experts looked at population data and estimated that 4. 5 more minutes of moderate walking and 11 extra minutes of sleep daily could improve hea
The study explores how a closure tool, used after artery procedures, changes the blood’s movement. These devices seal holes in the femoral artery quickly, cutting down on manual pressure and speeding up healing. Even though many doctors use them routinely, scientists have not fully mapped how the
A new study followed 217 people who had never taken pain pills before and were getting spine surgery between August 2023 and December 2024. The researchers divided the patients into groups based on how the surgery was done: a big open cut, a small tubular approach, or a very tiny endoscopic method.
The link between flu infections and heart problems is clearer now. Doctors once saw more heart attacks during cold seasons but didn’t know why. Recent studies explain the connection. Flu can trigger serious heart events, especially in people with existing heart disease. About half of adults hospita
After menopause, many women notice changes in their body that go beyond hot flashes. Research on mice shows these changes could link to a hormone-like substance called asprosin. After removing ovaries to mimic menopause in mice, scientists found that asprosin levels jumped higher in blood and fat ti
Early drops in kidney filtration and tiny amounts of protein in urine are now seen as red flags for future health problems. Scientists find that even small shifts in how well the kidneys clean blood can predict long‑term kidney damage and heart disease. These changes, called a mild decline in
In the United States, heart disease is the number one killer. Yet some jobs put people at extra danger because they make it hard to see a doctor and encourage habits that harm the heart. Researchers looked at men who cut down trees in Maine and catch fish off the coasts of Maine, Massachusetts, Ore
