Pink, when you turn out the light.

Well, tonight anyway — April’s full moon, often referred to as a “Pink Moon,” will be shining at its brightest 12:34 a.m. EST on Thursday, April 6.

But don’t be fooled by the name — despite its colorful moniker, this moon won’t look all that different from normal.

The name is said to have come from the timing of the celestial cycle, during early spring when the rosy-hued perennial known as phlox sublata, or “moss pink,” blooms in the eastern and central US.

According to the Royal Museums Greenwich, there have been long-held beliefs that the moon can affect human behavior, mental states, sleep and even menstrual cycles.

These ideas date back to ancient times, but have continued in folklore and popular culture.

Scientific evidence to back up such claims is scant, but some recent studies, including a 2021 one from scientists at Yale and the University of Washington, have linked the cycles of the moon to the way we sleep.

Researchers found that people went to bed later on nights before a full moon appears, due to greater light intensity after dusk.

 “In this context, it is primarily moonlight available during the first hours of the night that is more likely to drive changes in the onset of sleep,” the study explained.

‘”In contrast, moonlight late in the night, when most individuals are typically asleep, should have little influence on sleep onset or duration.” 

Stargazers will be able to see the moon for a few days, so long as there are clear skies.
