Can A Week Under Canvas Reset Our Body Clocks?

I found this interesting article on the BBC News website:

Researchers say that camping for a week can reset the biological clock that governs our sleeping patterns

The scientists argue that modern life disrupts our sleep through exposure to electric light and reduced access to sunlight.  But after spending time in the great outdoors, the researchers say the body clocks of eight volunteers synchronised with sunrise and sunset.  The research has been published in the journal, Current Biology.

All life forms on earth have evolved biological rhythms that anticipate sunrise and sunset.  Researchers have found that the widespread availability of electric lighting from the 1930s onwards has affected our internal circadian clocks, allowing us to stay up much later than evolution intended.
