(HealthDay)—Children with lower levels of daytime physical activity (PA) have higher hypothalamic-pituitary-adrenocortical axis (HPAA) activity in response to psychosocial stress, suggesting that PA may help children cope with stressful situations, according to research published online March 7 in the Journal of Clinical Endocrinology & Metabolism.

Silja Martikainen, of the University of Helsinki, and colleagues conducted a cross-sectional study of 258 8-year-old children to evaluate whether PA levels affected HPAA activity and HPAA response to psychosocial stress. PA was measured using a wrist accelerometer. Stressors included doing arithmetic and being assigned to tell a story.

The researchers found that, after exposure to everyday stressors, children with the highest levels of PA or vigorous PA showed very little, if any, increase in salivary cortisol levels when compared to more sedentary children in the lowest and intermediate PA groups.

"Our study shows that increased levels of PA are associated with decreased HPAA reactivity to stress in a community sample of 8-year-old children," the authors write. "Although children with different levels of PA show similar diurnal patterns of salivary cortisol, the children with the lowest activity levels are more responsive to psychosocial stress. Consequently, PA may contribute to the psychological well-being of by regulating their neuroendocrine reactivity to ."

It works well with adults, too.
Keep our minds off the BS going on in the world by keeping us busy chasing money, toys, pleasure, etc. As long as we're concentrating on keeping our heads above water and pursuing the pleasures that make our lives worth living; we won't have time to think about all the nasty crap governments and big corporations are heaping upon us.
