Why do we blow out candles on our birthdays?
Thanks for asking.
It's a scene that plays out in millions of homes across the world every day.
There's a sense of anticipation as the lights go out.
Only for the room to be lit up by candles as a friend or family member brings in a yummy looking birthday cake.
Guests start singing more or less in unison, more or less in tune, depending on how much alcohol has been consumed.
And the birthday girl or boy politely waits until they finish before blowing all the candles out.
The custom of getting a cake for someone on their birthday and putting candles on it is more or less universal.
But did you ever stop to ask yourself why we do it?
When did the tradition start out?
It goes back to ancient Greece, actually.
The custom was to celebrate birthdays by preparing a round pastry called amylos.
It symbolised the moon and was made up of batter, honey and sesame.
The cake would be taken to the temple of Artemis, goddess of wild nature, childbirth and hunting.
Finally, altar candles were lit around the cake and celebrants would drop to their knees to worship the goddess and then blow out the candles.
That pagan tradition had disappeared by the middle ages, as had any kind of birthday celebration, in fact.
The Catholic Church saw celebrating birthdays as sinful due to the connection between birth and original sin.
It was seen as more acceptable to honour a person's saint day according to their given name.
Birthday celebrations resurfaced in Germany in the 13th century.
Peasants created the tradition of Kinderfest for their children.
Cake was prepared and decorated with a number of candles equal to the child's age and one additional candle representing life.
The candles were lit over and over throughout the day until dinner, when the birthday child blew them all out in one go.
The tradition spread and became common in all western countries by the 19th century.
It was no longer limited to children either, meaning adults could also celebrate their birthdays.
Why do we make a wish when we blow out the Back?
In ancient Greek times it was said that the smoke created when blowing out candles helped prayers to reach the gods in the skies.
Later, when Kinderfest had started, popular belief suggested that a child who made a silent wish and then managed to blow out all their candles in one go would see their wish come true.
On the other hand, failing to do so would bring them bad luck.
In 2017, an American study found that blowing out candles over a cake increased the number of bacteria on its surface by 1400.
That might sound scary, especially having lived through the COVID-19 pandemic, but the study's director, Paul Dawson, told The Atlantic there was no need to worry.
He said that even if you blew candles out 100000 times over a cake, there would still be almost no risk of anyone getting sick.
That's because our mouths contain millions of bacteria, most of which are completely harmless.
So rest assured, you can continue to enjoy your birthday cake year in, year out without getting paranoid about germs.
