Wondering why you can never get a good night's sleep at a certain time of the month?
Don't worry, there's a completely legitimate reason why - the full moon.
And things may exacerbate even more so on Sunday night, when we get to experience an incredibly rare lunar event.
The blue moon refers to a rare lunar event when a full moon appears for a second time in the same month, hence the saying, "Once in a Blue Moon". Don't you just love the English language?
Interestingly, Sunday's full moon is referred to as a blue moon because it's the third full moon out of four during the Northern Hemisphere's summer season before the equinox.
So, the blue moon, although it'll look more orange or red than blue, is one of the rarest lunar sightings us humans can witness as it nestles between Jupiter and Saturn.
According to Space.com, the last time we got to witness a blue moon was in October and in fact, we won't get to experience such a sighting of three full moons during the solstice again until 2024.
Knowing this, it begs to question why we experience a very restless slumber around this lunar events? Well, the link between poor sleep and the moon has been debated for centuries.
In one study, researchers from the University of Basel in Switzerland found that on the nights around the full moon, people took longer to fall asleep; spent less time in a deep sleep; slept for less time and spoke about having had a poor night's sleep.
The study was a small group of just 33 people - but none of them had any idea the study was related to the impact of the moon.
Interestingly, one sleep expert told us that our sleep pattern and the full moon have been intrinsically linked since the Paleolithic period when we had to worry about predators.
The Sleep Geek, James Wilson told Tyla: "My theory as to why we sleep worse at this time is that when we had predators, a full moon would make us more vulnerable to being attacked and eaten.
"Therefore our bodies are designed to sleep more fitfully and therefore the quality and quantity of our sleep to be worse."
So, is it our instincts kicking in?
However, another lunar expert suggested that the energy of the full moon could have a direct impact on our psyche and emotions, leading us to become more unsettled both in the day and at night.
Astrologer Lisa Stardust told Tyla: "A full moon occurs when there's a polarity between the sun and the moon. This tug of war takes a toll on emotions and illuminates' truths to be exposed.
"Being that it's close to earth, the moon (who in astrology represents emotions) has a greater effect on our inner sentiments - most of which we cannot express."
So next time a full moon hits, give yourself a little credit because it's not your fault for tossing and turning.
