Researchers find connection between sunshine and ADHD

A recent study found a correlation between the amount of sunshine in a particular location and the prevalence of attention-deficit/hyperactivity disorder. While there are exceptions, such as Florida, places with a lot of sun tended to have fewer cases of ADHD, data show. Scientists are still looking for explanations, but they said changes in our biological clocks and sleep quality may be behind the apparent connection.
