Want your child to remain stress free? If yes, try relocating to a better neighbourhood as a new study has found less stress hormone in children with access to green spaces, clean air, and quality grocery stores.

The findings, published in the journal Psychosomatic Medicine, showed that the average cortisol level -- a biological marker of the body's stress response -- among 113 of low-income children who lived in poor neighbourhoods reached the 75th percentile.
