35 Love Facts That Will Amaze You

1. Love Makes Your Live Longer

Love and marriage may give you a longer life. According to a study published in the Journal of Marriage and Family, married people are 58% less likely to die over an 8-year period than people who never got married (1).

2. Love And Lust Affect Different Areas Of The Brain

One-night stands do not always result in a fairytale romance. Studies show that being in love activates the regions in the brain that are connected to empathy (2). However, lust is connected to the areas of the brain that are mainly associated with motivation and reward.

3. Red Rose Is The Official Flower Of Love

Red roses were linked to Adonis, the Greek god of beauty and desire. Legend has it that Adonis was killed by a wild boar in Aphrodite’s arms. His blood turned the white roses around him red. This is why red roses are seen as a symbol of love & sacrifice.

Have you ever wondered why roses are the symbol of love? This is because the rose is considered to be the favorite flower of Venus, the Roman goddess of love.

4. Love Makes You Do Crazy Things…

…like making a scene, escaping from jail to see the person you love, or just acting plain silly. Do you know what happened to Joseph Andrew Dekenipp, a prisoner in Arizona? He broke out of jail just so he could meet his girlfriend for Valentine’s Day.

5. The World’s Longest Marriage Lasted 86 Years

If you often complain that true love does not exist, just look up Herbert and Zelmyra Fisher. This couple holds the record for the longest marriage in history. They were married for a staggering 86 years and 290 days.

6. Love Makes You More In Tune With Your Emotions

When you find the one who makes you strive to be the best version of yourself, your brain also responds accordingly. According to a study published in Cognitive, Affective & Behavioral Neuroscience, the social connection that comes with being in a happy relationship activates the parts of the brain that are responsible for emotional processing and selflessness (3).

7. Love Develops In Phases

Anyone who has ever experienced love knows that it develops in phases. It increases in intensity gradually. It starts out strong and passionate but gradually mellows down into a more mature and understanding love.

protip_icon Trivia
The word “honeymoon” traces its roots to the Nordic and Germanic traditions, involving the consumption of a honey-based alcoholic beverage called mead. This practice symbolized fertility, love, and sweetness, and over the years, it evolved into the term “honeymoon phase” representing the initial, blissful stage of a romantic relationship.

8. Love Lowers Your Blood Pressure

We all know that high blood pressure is associated with a higher risk of stroke and heart disease. Fortunately, according to a study published in Annals of Behavioral Medicine, being happily married can result in lowered blood pressure (4). So, go and kiss your partner for keeping you healthy!

9. Love Helps You Heal Faster

Having your partner by your side when you are injured or sick does not just get you emotional support. When partners share a close bond, their injuries are claimed to heal faster compared to people who are in unhappy relationships.

The Netherlands Study of Depression and Anxiety (NESDA) included 1816 Dutch adults in a study focusing on the relationship between happiness and depression. A total of 2981 persons aged 18 to 65 years were included in the study over the course of three years. It concluded that happiness was inversely associated with psychiatric disorders and their severity.

10. Men Fall In Love Faster Than Women

A study published in The Journal of Social Psychology found that men take the first step when they fall in love (5). They are usually the ones who say “I love you” first in a relationship. This may be because women are more scared of getting their heart broken.

11. Being In Love Reduces Headache Frequency

If you have chronic headaches, love might be what you are looking for. A study conducted at the Stanford University School of Medicine found that 50% of the participants who were having a headache reported their pain reduced by half after around four hours when they were administered a nasal spray with a dose of oxytocin, a love hormone. An additional 27% stated that they did not feel any pain at all after the same duration (6).

12. Love And Laughter Go Together

If you want to be closer to your partner, watch a comedy TV show together. A study published in Personal Relationships found that couples who laugh together are more satisfied in their relationship and more supportive of each other when compared to those who were more serious with each other (7).

13. Distance Can Strengthen A Relationship

People often say that long-distance relationships don’t work, but research says otherwise. According to a study published in the Journal of Communication, long-distance relationships are not only as successful as regular relationships, but they are also better at building trust between partners (8).

Strengthen your long-distance relationships by being more intentional. You can do surprise online deliveries, organize video dates, have a virtual game night, and watch movies to keep the relationship exciting and dynamic.

14. Being In A Relationship Can Improve Your Personality

Pessimistic people are known to change for the better when they fall in love. A study published in the Journal of Personality observed 245 young couples for nine months (9). The scientists found that neurotic partners in a relationship became more self-confident and optimistic because of all the positive experiences and emotions that come with being in a relationship.

15. Love Can Ease Chronic Pain

Love is not going to replace modern medicine any time soon. However, it can come in handy if you ever experience serious pain. In a study conducted by the Stanford University School of Medicine, researchers found that the warm and fuzzy feeling that love creates has the same response in the brain as strong painkillers do (10).

16. Cuddling Is Good For You

There’s a good reason why couples love cuddling so much. Cuddling triggers the release of oxytocin, the happiness hormone that improves your mood and increases your feeling of well-being. That is why oxytocin is referred to as the “love hormone” or the “cuddling hormone.”

17. Love Is Chemically Addictive

Romantic love can be a very powerful addiction. This is because the hormones that your brain releases when you are in love are euphoric. In fact, you may get so high that it can make you feel addicted to love as well as to the person you are in love with.

18. Love Is The Number One Reason Why People Get Married

More than 60% of the world’s population are claimed to cite love as the reason they got married. The rest stated that financial stability was their determining factor.

Ronald Hoang, a Relationship and Family Counselor, shares an interesting fact, “The idea of romantic love leading to marriage is a contemporary concept. Marrying the “love of your life” is a modern idea. People used to marry for economic reasons – marriage used to be pre-arranged and families would marry their children to improve the financial status of the family.”

19. The Heartbeats Of A Couple Are Synchronized

When you and your partner gaze into each other’s eyes, your heart rates sync up. This has been stated by scientists at the University of California. The researchers found that a couple’s heart rates can be almost identical. This may be because of the strong link between couples on both a physical and an emotional level (11).

20. Animals Can Be Monogamous As Well

Humans are not the only species on the planet that have monogamous relationships. Wolves, seahorses, beavers, otters, and barn owls are a few of the other species that mate for life.

21. Hugging Your Partner Can Relieve Stress Instantly

Feeling stressed? Hug it out with your partner. According to a study conducted by the University of North Carolina, when couples hug, it increases the level of oxytocin in their bodies (12). As mentioned earlier, oxytocin reduces stress and boosts your mood. So if you are having a rough day, ask your partner to give you a tight hug!

22. Falling In Love Feels Like Being On Drugs

That feeling of euphoria you experience when you fall in love is essentially the same feeling that drug users experience (13). Both of these events trigger the release of hormones like adrenaline, dopamine, and oxytocin that give you a real high.

23. It Can Take Just 4 Minutes To Feel Attracted To Someone

If you wish to make a good impression on someone, you only have about 4 minutes to do so. It is believed that it has more to do with the tone of your voice and your body language than what you actually say.

24. Both Men And Women Must Have A Certain Level Of Testosterone For Sexual Attraction

Yes, even girls have small amounts of testosterone in their bodies. Testosterone is responsible for arousing desire as well as aggressive behavior – which actually pushes the person to pursue the object of their desire.

25. Being In Love Has A Similar Neurological Effect As That Of Cocaine

Being in love is almost like snorting cocaine. Both experiences trigger a similar sensation. Researchers have found that being in love can result in the production of several euphoria-inducing chemicals, which stimulate 12 areas of the human brain at the same time (14).

26. Couples Who Are Very Similar To Each Other Are Not Likely To Last

Everyone knows that opposites attract. Research proves that this is at least partially true. Partners who are too similar or too different don’t last very long. There must be some similarities, but there also have to be some differences so that the two people can learn from one another.

27. Heartbreak Is Real

There is evidence that severely traumatizing events – such as a divorce, death of a loved one, a break-up, physical separation, cheating, or betrayal – can cause real physical pain around the heart. This condition is known as Broken Heart Syndrome (15).

Intense emotional distress triggers the brain to release certain chemicals that weaken one’s heart, leading to shortness of breath and chest pain. This condition is so intense that it is often misdiagnosed as a heart attack. It affects women more often than men.

28. People In Love Have Hormonal Levels Similar To People With OCD

People in the early stages of love are said to have lower levels of serotonin, a hormone that is directly associated with feelings of well-being and happiness. They also have higher levels of cortisol, which is associated with stress. This is very similar to the people who have OCD or Obsessive Compulsive Disorder.

This explains why we don’t behave like ourselves when we fall for someone. It works the other way as well – people who have lower levels of serotonin tend to fall in love and get involved in sexual relationships quicker than others.

29. The Feeling Of Butterflies In The Stomach Is Real

When you fall in love with someone, you can feel the butterflies in your tummy every time you see that special someone. This sensation is caused by adrenaline, which is released in your body as a flight-or-fight response.

30. Dilated Pupils Show That You Are Attracted To Someone

Your pupils expand during heightened focus and attention. This is true – it usually occurs when people gaze at the object of their desire, even if it is only a video or a picture. Moreover, people who have dilated pupils look more attractive to others.

31. You Are Attracted To People With A Different Immune System

If this isn’t weird, we don’t know what is. This was observed during a study at the University of Switzerland where the female test subjects smelled worn men’s T-shirts (16). They consistently preferred the smell of those men’s shirts whose immune systems were different from their own.

32. Some People Can’t Feel Love

Some people who claim never to have fallen in love or felt romantic love may be affected by a condition called hypopituitarism that does not allow people to feel the high of love. Of course, it is also possible that said people are aromantic.

33. Your Body Has A “Vein Of Love”

Why are engagement rings worn on the fourth finger of the left hand? That is because the ancient Greeks believed that this finger has the vena amoris, or the”vein of love,” that connects straight to the heart. So romantic!

Apart from the above mentioned facts, there are some truly interesting psychology-based ones you should know about.

Psychological Facts About Love

34. Love Is Based On Chemical Bonding

Love triggers the release of neurotransmitters, namely dopamine, oxytocin, and serotonin. Dopamine, associated with pleasure, reinforces the desire for connection, while oxytocin fosters bonding and a sense of security (17). Serotonin, linked to mood regulation, enhances feelings of happiness. This chemical interplay strengthens the emotional bond between a couple and explains the addictive nature of love, linking it with pleasure and reward.

35. Partners Follow Certain Attachment Styles

Love is influenced by attachment styles developed in one’s childhood (18). Attachment theory suggests that people exhibit secure, anxious, or avoidant attachment patterns. Those with secure attachments grow up to form healthy, trusting relationships, while anxious kids may deal with abandonment issues, seeking constant reassurance. Avoidant children may struggle with intimacy and distance themselves emotionally.

It is a well-known fact that love is one of the strongest emotions you can feel. It makes you feel the highest of highs and the lowest of lows, but true love can be wonderful to experience in your life. For instance, it makes you feel more connected to your emotions, lowers blood pressure, and even reduces the frequency of headaches! Not just that, being with someone you love and who loves you can positively impact your personality by making you more confident and optimistic. Isn’t that wonderful?
