FDA and Sunscreen, Movies, Time Zone Circadian Rhythm

FDA and Sunscreen Guest: Kerry Hanson, Research Chemist, University of California, Riverside Memorial Day weekend is when outdoor pools open in places around the country where pools close during the winter. That makes it the official start of summer for a lot of us. This year it also coincides with the end of a public comment period on new sunscreen regulations being considered by the US Food and Drug Administration.

Suddenly theaters were flooded with movies based on young adult novels about dark futures where teenagers band together to fight the forces of evil (usually adults).

That means on many days, people in Amarillo are waking up while it’s still dark outside, but further east over in Nashville, the sun’s already up when the alarm goes off. Now that might just seem like a quirk of the time zone system. But more and more studies are finding that situations like that can have serious health consequences.
