Participating in sports is good for physical health. But take a look at other specific ways it can benefit a girl’s health as she is participating.
Fewer chronic illnesses
Girls who play sports have stronger immune systems and a reduced risk of chronic illnesses. 
Higher body esteem
There is a positive relationship between athletics and body esteem among girls. Girls who play sports are also 16% less likely to want to change their image. 
Girls who play sports have lighter and more regular periods. They also tend to experience less cramping and discomfort. 
Girls who participate in sports have stronger bones and a reduced risk of osteoporosis.  As written in the Guardian, studies “have found that bones retain a ‘memory’ of early-life exercise before the onset of puberty that lasts long after the exercise has ceased and provides health benefits even in a relatively sedentary adulthood.”
