Safe open-water swimming this winter could delay dementia, says a ground-breaking new study
According to recent research from Cambridge University, the benefits of swimming outdoors this winter could last a lifetime, with evidence that regular cold-water swimming may be an effective defence against dementia. The blood profiles of winter swimmers were monitored over several years and shown to feature significant levels of a protein called RBM3 that’s been shown to slow the onset of dementia in mice.
In 2015, the same Cambridge team discovered this protein after placing degenerative mice into a hypothermic state. RBM3 seemed to decelerate neural breakdown, providing a sort of dementia shield. Professor Giovanna Mallucci, who led the test, said the discovery could point researchers toward new drug treatments but also warned about the dangers of cold-water swimming. We highlighted those last issue, though also revealed the strategies and gear to safely swim outdoors this winter. And it’s worth it, both for your triathlon performance and potentially your long-term mental health.
