Medical Notes: How To Lower Your Dementia Risk, Fighting Dehydration With Fitness, And Is Your Environment Killing You?

Good news! Your genes don’t have the final say when it comes to your brain health.

New research shows that controlling risk factors like high blood pressure can significantly lower dementia risk even for those carrying the high-risk gene variant. So while you can’t change your DNA, managing your blood pressure and cardiovascular health provides a powerful, modifiable way to avoid the worst outcomes. The research published in Annals Of Neurology.

Too much of a popular supplement could be setting the stage for unexpected birth defects.

A study published in Frontiers In Cell And Developmental Biology warns that high doses of common antioxidants, like NAC, can negatively alter sperm DNA. In mouse models, this change led to differences in the offspring’s skull and face shape. Even when the father appeared perfectly healthy, his high intake of antioxidants resulted in female offspring with smaller skulls and closer-set eyes. NAC is a key ingredient in many multivitamins, so it’s important to pay attention to how much you’re ingesting past the recommended daily amount.

According to a study published in Jama Health Forum, researchers found large disparities in life expectancy across the world.

The researchers cite japan as the place to be for longevity.

The secret to overcoming dehydration might be your fitness level.

New research published in Physiology And Behavior, suggests that physically fit people may have a buffer that helps the brain and body maintain performance when water is scarce. While staying hydrated remains essential, these findings imply that being in peak shape could be a huge advantage for outdoor workers and athletes facing an increasingly warming world.
