7. Women Have a Better Sense of Smell than Men

This was one that I wasn’t surprised to hear. I can recall many women in my family who have mentioned the presence of odors that none of the men could detect.

I found this fact surprising, since I thought a person would be able to smell things much better as soon as he/she woke up. It’s a new day, you haven’t been inhaling random smells throughout the house and town, and so wouldn’t that give you a fresh slate to work with? I guess not.

2. The Nose Can Absorb up to 10,000 Smells at One Time

This intake of smells can come from an area no larger than a postage stamp too. I didn’t know that many scents could even fit in that small of an area, let alone be picked up by the human nose. I think that’s pretty amazing stuff!

1. Smells Are Linked to Memories

Have you ever picked up an aroma that made you remember a specific event from your childhood? If you have, then you’ve experienced this fact in action. There was even a study performed in Germany where people were put in a room scented with roses to play a game which involved matching cards. As the group slept, some individuals were given a whiff of roses and others weren’t. The next day when the same game was played and the cards were placed in the exact location as the day before, the test subjects who received the whiff of the roses in the night could remember where more of the matching cards were than the other test subjects could.

There are so many cool things about a person’s sense of smell, as well as all the other senses. Have you heard any interesting facts about a human’s sense of smell?
