Light pollution is not only bad for plant and animal life – and waste an estimated 30% of electricity in sky glow – this paper explains how it stops you getting to sleep – and makes you feel sleepier during the day. – Artificial Outdoor Nighttime Lights Associate with Altered Sleep Behavior in the American General Population
