Science has shown that caffeine-loaded drinks can raise kids’ blood pressure and drop their heart rate. Now, a study suggests the effects differ between boys and girls once they hit puberty. Researchers gave caffeine in doses roughly equal to zero, one, or two 12-ounce sodas to 50 kids ages 8 and 9 and 46 teens ages 15 to 17. Among the teens—but not the younger kids—caffeine had a greater effect on boys’ heart rate and blood pressure than on girls’. Caffeine influenced girls’ heart rates more before their monthly period, while its effect on blood pressure was greater during ovulation.
