So my theory is, someone was watch cattle or pigs cover themselves in mud and said to themselves, “Hey, this looks like a great way to care for your skin because you hardly ever see a cow or pig with a pimple!” It is true that mud has some healing properties and if can keep you cool until it starts to dry but you really need to make sure you are using clean mud (If there is such a thing) since bugs like to climb in mud too. And if you want clean mud, you have to pay a lot for it! Just make sure you don;t get mud in your eye.
How to celebrate – Find some mud and dive in! Make your own clean mud. Do some mud wrestling!
