Teenage boys more sensitive to caffeine

Caffeine is hard to avoid these days. No longer just in coffee, tea and colas, it’s now added to many new products – from energy drinks to snacks and candy.

While it has been known for some time that caffeine raises blood pressure and lowers heart rate, a new study in The Journal of Pediatrics reveals how it affects boys and girls differently after puberty.

The report, from the University of Buffalo, studied the impact of small amounts of caffeine on children ages eight to nine and on teenagers ages 15 to 17. The younger children received the amount of caffeine equivalent to a half can of soda, while the teenagers received the equivalent of one to two cans’ worth.

Results indicated that the teenage boys experienced slightly higher blood pressure levels than the girls. While researchers are not sure why teenage boys are more sensitive to caffeine, they suspect it has to do with hormones.
