Happy National Fragrance Day, everyone!

According to NationalDayCalendar.com, perfume manufacturers created this holiday in the 1980s to celebrate all the things scents can do for you. To celebrate, we hope you're smelling something good or picking up a new scent. We could go on forever about all the different ways you can celebrate. For us, we wanted to share with you some fun facts about fragrances you might not know. 

1. The first form of perfume was incense

According to McGill University, perfume was first created by the Mesopotamians over 4,000 years ago. Perfume -- well, incense -- was first used exclusively in religious ceremonies. By 3000 B.C., perfumes had made their way to Egypt for religious use. Eventually, the priests gave up their exclusive rights to perfume, allowing citizens use them. Citizens often used scented oils in their baths for fun. 

2. Smelling coffee between scents does not help reset your nose

According to Huda Beauty, although smelling coffee is supposed to cleanse your palette, it doesn't. In fact, it can make your nose even more confused. If you want to reset your nose, you should smell something neutral. Some outlets report that smelling something like your own skin can help reset your nose. 

3. The first perfume "nose" was a woman 

According to Perfume Society, a Mesopotamian chemist named Tapputi was the first "nose," or perfumer. A written document of her from 2000 B.C. showed that she had access to Mesopotamian ingredients such as fir, myrtle, woods, and resin to create incense. The most coveted scent was cedar. 

4. The most famous perfume of all time is from Chanel

Various outlets report that the best-selling and most iconic scent of all time is the classic Chanel No. 5. According to Harper's Bazaar U.K., Ernest Beaux created the famous scent in 1921. Chanel said that Gabrielle "Coco" Chanel asked the famous perfumer to create "a woman's perfume, with a woman's scent." She asked for something a bit different then the one-note scents that were popular at the time, so this was a big challenge. In 1986, Jacques Polge updated the scent to provide a fuller version, and it has not changed since. 

5. Greeks created the first liquid perfume

Ancient Greeks took their perfume and scent very seriously. It was part of worship and sometimes their funeral ceremonies. The Greeks were not super happy with burning the scents, so they tried something else. Perfume Society said the Greeks ground plants and resin and put them in oil, which was how we got the first perfume that you could wear on your skin.  

6. You can detect a trillion odors

Although you have your favorites, you can smell at least a trillion different scents, according to a 2014 study. It has yet to be determined exactly how many scents humans can identify. Prior to this study, it was estimated that humans can distinguish 10,000 different odors.
