The Dark Side of Light

There is research out of the US that suggests exposure to light at night may be a contributing factor towards obesity.  Trials conducted on mice (which have a similar genetic structure to humans) show that those exposed to higher lighting levels at night will gain more weight (up to 50%) than those with darkness at night.  The timing of food intake also is a factor – the later, the more likely this is to cause weight gain.  It’s a really interesting article which may be read in full by clicking to link to the Economist’s website.
