Scientists find bone pressure boosts mouse lifespan in China
Researchers in China discovered that gently squeezing mouse bones can extend their lives significantly.
Scientists at Southern Medical University tested elderly mice by applying rhythmic pressure to their shinbones regularly over time. This simple mechanical stimulus helped the animals live longer while improving their overall physical coordination and mental memory skills.
The study identified that a specific channel called PIEZO1 inside bone cells detects these physical forces and sends vital signals to the body. When researchers blocked this channel chemically, the mice aged much faster and suffered damage to their brains and muscles.
Applying pressure boosted levels of a protective protein known as PEDF which circulates in the blood to repair tissues throughout the body. This treatment reversed aging signs in organs and helped restore the immune system to a much younger and healthier functional state.
Although the study used mice, it suggests that regular exercise might help humans by triggering similar protective chemical signals from their bones. The findings highlight how movement maintains health beyond just building muscle strength or improving cardiovascular endurance levels directly.
“The findings contribute solid evidence in support of staying active as your birthdays pile up.”
