I was just wondering how can i improve my environmental health?

Two quick tips: In your outside environment one of the biggest risks is sun damage to your skin. As the Aussies say - Slip, Slap, Slop! Slip into protective clothing, slap on a brimmed hat, and slop on the sunscreen. Keep that healthy pallor of winter throughout the year! Work spaces inside can be made healthier with good back and arm positioning at the desk [ergonomic review], and avoiding abrupt twisting.
