It sounds impossible, but the very bright light emanating from a lighthouse at night attracts  birds. This happens on the most remote of lighthouses, some far out at sea.

What interest would birds have in a lighthouse?

Well sometimes it is because the light beacon attracts numerous insects which the birds feed upon. In other cases birds fly to the lighthouse lamp because it is the only attraction in their universe, just like a boat will navigate towards the safety of a lighthouse. Continue reading

I wrote an article entitled I Love Nightshift awhile ago. It is true, and now I know why I felt so healthy working on the lighthouse – lack of electric lights!

Electric Lights Alter Daily Rhythms

Humans’ circadian clocks become skewed when they are exposed to electric lights but revert to a schedule more in tune with the sun when they go camping.

Long-term exposure to electric lighting has fundamentally altered humans’ circadian rhythms, according to a study published in Current Biology last week (August 1). But a week camping away from electric lights swiftly reset eight study participants’ circadian clocks.

“What’s remarkable is how, when we’re exposed to natural sunlight, our clocks perfectly become in sync in less than a week to the solar day,” coauthor Kenneth Wright, a University of Colorado Boulder integrative physiologist, said in a press release. Read more . . .
