Children's Health: Study finds inadequate hydration among US children ♦ Most heart muscle cells formed during childhood ♦ Active video gaming compared to unstructured outdoor play

Study finds inadequate hydration among US children More than half of all children and adolescents in the US are not getting enough hydration -- probably because they're not drinking enough water -- a situation that could have significant repercussions for their physical health and their cognitive and emotional functioning.
Most heart muscle cells formed during childhood New human heart muscle cells can be formed, but this mainly happens during the first 10 years of life. Other cell types, however, are replaced more quickly. The study demonstrates that the heart muscle is regenerated throughout a person's life, supporting the idea that it is possible to stimulate the rebuilding of lost heart tissue.

Weekend screen time linked to poorer bone health in teen boys Weekend screen time is linked to poorer teen bone health -- but only in boys. The apparent lack of impact of leisure screen time on teen girls' bone health may be explained by their different body fat distribution.
