The world is transfixed by the rise of any supermoon. But did you know that these events influence life on Earth?

It’s no secret that the Moon’s gravitational pull changes the ocean’s tides, but during super moons the impact is even more pronounced.

Supermoons are also known as perigee moons, at these times the orbit of our rocky companion brings the satellite to its closest point to Earth. Bulges in the ocean form as the gravitational pull of the moon passes by, creating tides.

Research shows that oceans produce bigger tides, reach higher water levels, and cause more severe erosion at times of a supermoon.

Meaning those living in coastal areas could be at a higher risk of flooding during these events. With global sea levels rising, the impact of each supermoon will only become more pronounced.

There is also an impact on people, in fact the word ‘lunatic’ has its roots in the Latin for moon - luna - and the belief that changes in the moon cycle could cause insanity.

Looking at sleep, a research study released last year by Sweden’s Uppsala University suggests men are more affected by the moon than women. During its waxing phase, men slept 20 minutes less on average with greater restlessness and lower sleep efficiency as the full moon approaches. Meanwhile, women saw 12 minutes less sleep.

The lunar cycle has also been linked to changes in our cardiovascular health. One study shows that our blood pressure can drop by 5 millimetres Hg during times of a full or new moon. Even our heart rates are slower when the full moon arrives.

Although the moon can make small changes to our behaviour, it is unlikely to be a cause of lunacy. You may have simply had a little less sleep last week... although that could also have been thanks to the heatwave too!
