Running is widely praised for its powerful health benefits. Regular exercise can improve cardiovascular health, build muscle, strengthen bones, and reduce stress. But when it comes to extreme endurance events, such as ultramarathons, the story may be more complicated.
Researchers with the American Society of Hematology report that ultramarathon runners may experience accelerated aging at the cellular level. The strain of extra-long running sessions can damage red blood cells, potentially triggering inflammation throughout the body. While moderate running supports overall health, experts suggest that pushing the body to extremes may come with unintended consequences.
In another area of research, scientists are uncovering why certain substances create a cooling sensation. A study presented by the Biophysical Society identified a sensory receptor in the body that acts like a microscopic thermometer. This receptor signals the brain when temperatures drop — and it also explains why menthol, eucalyptus, and mint feel cool on the skin, even when they don’t actually lower temperature.
Meanwhile, recovery from injury remains a challenge for many Americans. A new survey from Ohio State University reveals that 76 percent of patients admit they don’t complete their prescribed physical therapy exercises at home. Physical therapists warn that skipping these exercises can slow healing, worsen injuries, and even lead to additional medical treatment.
Together, these findings highlight a common theme: whether pushing physical limits or recovering from injury, balance and consistency are key to protecting long-term health.
