The oldest references to a love letter date back more than 5,000 years to Indian mythology. It is mentioned in the Bhagavatha Purana and is addressed by Princess Rukmini to King Krishna, and carried to him by her messenger Sunanda.

Over the next few thousand years, love letters were used by people to express their love for another human being. Historically, it has been known as the most romantic way for one person to convey their emotions to another person, so it’s no wonder that a holiday was created around it. This holiday is called Love Note Day, and it is celebrated on the 26th of September.

Facts About Love

If you’re interested in Love Notes and Love Note Day, we figured you’d be interested in some fun facts about love. Love is one of the core emotions of humanity, and great works of art have been inspired by it, so why not find out a little bit more by exploring some of the factoids below?

Falling In Love Produces Feelings Of Euphoria

Although most people who have been in love don’t need a scientific study to confirm their feelings, it is interesting to note that falling in love does produce a sense of euphoria in the human mind. This euphoria is triggered by the release of hormones such as dopamine, adrenaline, and oxytocin.

Love Is Good For The Heart

Several studies have shown that married people 49 years old and younger are less likely to have vascular diseases compared to single people of the same age. In fact, they can have up to 12% less of a chance of having a healthier heart.

Love Eases Chronic Pain

Some studies have shown that the brains of couples produce the same response as their brains do to painkillers—just on a lessened level. While this effect isn’t going to replace traditional painkillers anytime soon, it is nice to know that being in love takes the edge off chronic pain at least a little bit.

Being In Love Cuts Headache Frequency By Up To 50%

Yes, you read that headline right. Being in love reduces your chances of getting a headache by half. This is probably due to the production of oxytocin in the brain. Oxytocin is known as the love chemical, and it shows up in people who just so happen to be in love.

Studies Show Men Fall In Love Faster Than Women

Although women have traditionally been seen as more emotional than men and therefore more likely to fall in love, science shows that the opposite is true. Men are actually the ones who have been shown to say “I Love You” quicker than women in a relationship.

Observing Love Note Day

To celebrate this holiday, all a person has to do is give someone they love a love note. It can be a significant other, or you can pen a note of affection for friends and family members. They can also leave a small love note on their social media posts and tag it with the hashtag #LoveNoteDay.
